BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a display apparatus and a method for driving a display panel thereof. More particularly, the present invention relates to an LCD display apparatus and a method for driving a display panel thereof.

2. Description of Related Art

In order to satisfy the demands for display quality of LCD TV market, liquid crystal display panels are developed gradually towards specifications of high resolution, impulse systems, and high frame rates. However, the above specifications will influence charging time which is already at the margin, and the details are described as follows.

FIG. 1 is a schematic view of the architecture of a conventional display system of double frame-rate. A display panel 101 of the system is divided into an upper half part and a lower half part, and gate drivers 102 and 103 at left and right sides of the display panel 101 are used to drive scan lines (not shown) of the display panel 101, so as to further turn on pixels coupled to the scan lines. Meanwhile, source drivers 104 and 105 on upper and lower sides of the display panel 101 are also used to provide display data required by pixels that have been turned on in the upper half and the lower half parts, respectively.

The above system also adopts the impulse system technology, and the signal timing in the system is as shown in FIG. 2. FIG. 2 is a timing diagram of signals of the system of FIG. 1. STV1-STV4 are gate start driving signals, VCLK is a clock signal, OE is an output enable signal, /OE is an inverted signal of OE, and VG1-VGn are gate pulse signals. As shown in FIG. 2, the impulse system technology adopts a time-division driving method of each scan line to separate the writing time of image data and reset signal (for inserting black frames). In addition, it would be known from FIG. 2 that if the writing time of the image data and the reset signal is averaged, the effective charging time of the two is H/2-Trc. Here, H is scan time of the scan lines, and Trc is delay time of RC. If the writing time of the image data and the reset signal is not averaged, for example, the image data is written for the time of 2H/3 and the reset signal is written for the time of H/3, the effective charging time of the image data and the reset signal is 2H/3-Trc and H/3-Trc, respectively.

The reset signal for inserting black frames is originally used to solve the problem of motion blur generated by hold-type display. However, under the condition of improving the frame rate, the charging time will be at the margin. Even if the charging time of the image data is extended, the charging time of the reset signal will be insufficient, which results in ineffective charging, and the target value of the reset signal cannot be obtained. Therefore, the performance of the analog impulse type display will be degraded, and the problem of motion blur cannot be solved effectively.

DESCRIPTION OF EMBODIMENTS

FIG. 3 shows a display apparatus according to an embodiment of the present invention. The display apparatus includes an arithmetic unit 301, a data reorganization unit 302, a timing controller 303, and a display panel 304. The operations of the above components will be briefly described as follows. The arithmetic unit 301 generates a reset data RD according to an input image signal DATA1 and a counting relation that is related to a plurality of image segments (which will be described later). The reset data RD may be a black or a white image data, or an image data of any single grayscale. The data reorganization unit 302 receives the input image signal DATA1 and the reset data RD, and reorganizes the input signal DATA1 and the reset data RD, so as to generate an image signal DATA2. The timing controller 303 receives the image signal DATA2, so as to generate a plurality of control signals CS according to the image signal DATA2. Moreover, the timing controller 303 sends the plurality of control signals CS and the image signal DATA2 to the display panel 304, so as to control the display of the image signal DATA2 on the display panel 304.

FIG. 4 is an embodiment of the display panel of FIG. 3, and shows the coupling relationship between the internal components of the display panel 304 and the timing controller 303, and the image signal DATA2 and the plurality of control signals CS sent to the display panel 304 by the timing controller 303. The plurality of control signals CS includes a gate clock signal CPV, a gate start driving signal STV, and output enable signals OE1-OE4. The display panel 304 includes a gate driver 401, source drivers 402 and 403, 16 rows of scan lines, N columns of data lines, and 16×N pixels. The 16 rows of scan lines are denoted by G53₁-G53₄, G54₁-G54₄, G55₁-G55₄, and G56₁-G56₄ respectively. Each column of the data line includes a first sub-data line and a second sub-data line. The first sub-data lines are denoted by D₁-D_N respectively, and the second sub-data lines are denoted by D₁-D_N, respectively. The 16×N pixels are arranged in a matrix, and the coupling relationship of a column of pixels in the pixel matrix is shown in this figure. For example, the pixel 404 is coupled to the scan line G53₁ and the sub-data line D₁, and the pixel 405 is coupled to the scan line G53₂ and the sub-data line D_1′.

The gate driver 401 further includes four scan units, which are denoted by 53-56 respectively. Each of the scan units drives four rows of scan lines. For example, the scan unit 53 drives the scan lines G53₁-G53₄ according to the gate clock signal CPV, the gate start driving signal STV, and the output enable signal OE1. After the gate driver 401 receives the gate start driving signal STV, the gate start driving signal STV is transferred inside the scan unit 53 first, and is gradually transferred to the scan unit 56. When a scan unit receives the gate start driving signal STV, the scan unit drives the scan lines coupled thereto according to the position where the gate start driving signal STV is transferred to, and the source drivers 402 and 403 send the image data corresponding to the image signal DATA2 at the same time.

The data reorganization method of the input image signal DATA1 and the reset data RD is illustrated, and then the operation of the circuit in FIG. 4 will be described in detail. FIG. 5 is a schematic view of a data reorganization method according to the embodiment of FIGS. 3 and 4. Referring to FIG. 5, DE1 is a data enable signal corresponding to the input image signal DATA1, DE2 is a data enable signal corresponding to the image signal DATA2, CPV is the above gate clock signal, and OED and OEB are two signal forms of each of the output enable signals (OE1-OE4). The input image signal DATA1 has a plurality of image segments. Each of the image segments has the display data of the pixels coupled to two adjacent scan lines. For example, the image segment 501 has the display data of the pixels coupled to the scan lines G53₁ and G53₂, and the image segment 502 has the display data of the pixels coupled to the scan lines G53₃ and G53₄.

In this embodiment, every two image segments are defined as one group, and a reset data RST is inserted into each group of image segments. Thus, a time segment Tcycle originally having two batches of data have three batches of data, and the reset data RST is arranged after the image segments of each group. Therefore, the arithmetic unit 301 must generate the positions to arrange the reset data RST according to such a counting relation. In addition, as the image signal DATA2 is obtained through data reorganization, the image signal DATA2 is naturally delayed for a time of Tdelay compared with the input image signal DATA1. After the image signal DATA2 is obtained, the signal form of the output enable signal received by each of the scan units must be controlled properly, so as to control the corresponding scan lines properly according to the data timing of the image signal DATA2, so as to allow the pixels to receive correct loading data. That is to say, when the output enable signals assume the OED form, and are at a low level (represented by T1), the display data are loaded into the corresponding pixels. When the output enable signals assume the OEB form, and are at a low level (represented by T2), the reset data are loaded into the corresponding pixels.

FIG. 6 is a timing diagram of a part of signals of the circuit in FIG. 4, and shows the timing of the gate clock signal CPV, the two forms of output enable signals (OED and OEB), the gate start driving signal STV, and gate pulse signals between the scan lines. The gate start driving signals STV has two start waves, which are denoted by STVD and STVB, respectively. Referring to FIGS. 4 and 6 together, the operation of the circuit of FIG. 4 is described in more detail. When the timing controller 303 sends the start wave STVD to the scan unit 53, and provides the output enable signal OE1 in the OED form to the scan unit 53 and provides the output enable signal OE3 in the OEB form to the scan unit 55, the scan unit 53 will operate according to the start wave STVD, the gate clock signal CPV, and the output enable signal OE1 in the OED form.

With the transfer of the start wave STVD in the scan unit 53, the scan unit 53 drives the scan lines corresponding to the first group of the image signal DATA2 in two batches, and drives two adjacent scan lines each time. That is to say, when the output enable signal OE1 in the OED form is at a logic low level, the scan unit 53 will drive two scan lines at the same time. For example, the scan unit 53 first drives the scan lines G53₁ and G53₂ at the same time, and then drives the scan lines G53₃ and G53₄ at the same time. At the same time when the scan unit 53 drives the scan lines G53₁ and G53₂, the source driver 402 outputs the display data of the pixel coupled to the scan line G53₁, and the source driver 403 outputs the display data of the pixel coupled to the scan line G53₂. At the same time when the scan unit 53 drives the scan lines G53₃ and G53₄, the source driver 402 outputs the display data of the pixel coupled to the scan line G53₃, and the source driver 403 outputs the display data of the pixel coupled to the scan line G53₄.

After a short period of time, the start wave STVD is transmitted to the scan unit 54. At this time, the timing controller 303 provides the output enable signal OE2 in the OED form to the scan unit 54, and provides the output enable signal OE4 in the OEB form to the scan unit 56. After the scan unit 54 receives the start wave STVD, the scan unit 54 also drives the scan lines corresponding to the second group in the image signal in two batches, i.e., drives the scan lines G54₁ and G54₂ at the same time first, and then drives the scan lines G54₃ and G54₄ at the same time. At the same time when the scan lines G54₁ and G54₂ are driven, the source driver 402 outputs the display data of the pixel coupled to the scan line G54₁ correspondingly, and the source driver 403 outputs the display data of the pixel coupled to the scan line G54₂ correspondingly. At the same time when the scan lines G54₃ and G54₄ are driven, the source driver 402 outputs the display data of the pixel coupled to the scan line G54₃ correspondingly, and the source driver 403 outputs the display data of the pixel coupled to the scan line G54₄ correspondingly. More generally, at the same time when two adjacent scan lines are driven, the source driver 402 outputs the display data of the pixels coupled to the (i)th scan line among the scan lines that have been driven correspondingly, and the source driver 403 outputs the display data of the pixels coupled to the (i+1)th scan line among the scan lines that have been driven correspondingly.

Then, the timing controller 303 sends the start wave STVB to the scan unit 53. That is, after a predetermined time since the start wave STVD is output, the timing controller 303 outputs the start wave STVB. Meanwhile, the timing controller 303 provides the output enable signal OE3 in the OED form to the scan unit 55, and provides the output enable signal OE1 in the OEB form to the scan unit 53. Then, the start wave STVD is also transmitted to the scan unit 55. Therefore, the scan unit 53 starts to operate according to the start wave STVB, the gate clock signal CPV, and the output enable signal OE1 in the OEB form. The scan unit 55 also starts to operate according to the start wave STVD, the gate clock signal CPV, and the output enable signal OE3 in the OED form. Definitely, the above predetermined time may be set according to actual requirements, and is not limited to this embodiment.

The output enable signals in either the OED form or the OEB form must be at the logic low level to enable the scan lines. Therefore, when the scan unit 55 drives the scan lines (G55₁-G55₄) corresponding to the third group in the image signal according to the start wave STVD, the gate clock signal CPV, and the output enable signal OE3 in the OED form, as the output enable signal OE1 in the OEB form is at a logic high level, the scan unit 53 will not drive the scan lines coupled thereto. Moreover, since no start wave is transmitted in the scan units 54 and 56 at this time, the scan units 54 and 56 will not drive the scan lines coupled thereto as well.

At the same time when the scan unit 55 drives the scan lines coupled thereto, the source driver 402 will output the display data of the pixels coupled to the (i)th scan line among the scan lines that have been driven correspondingly, and the source driver 403 will output the display data of the pixels coupled to the (i+1)th scan line among the scan lines that have been driven correspondingly. Then, the output enable signal OE3 in the OED form assumes the logic high level, and the output enable signal OE1 in the OEB form assumes the logic low level. Therefore, during this period of time, the scan unit 53 drives the scan lines G53₁-G53₄ at the same time, and meanwhile the source drivers 402 and 403 output the reset data as well, so as to reset the display data of the pixels coupled to the scan lines G53₁-G53₄. Thus, the problem of motion blur of these pixels is avoided, and the effect of an impulse system is realized.

Then, the start waves STVD and STVB will be transmitted to the scan units 56 and 54 respectively, and the timing controller 303 provides the output enable signal OE4 in the OED form to the scan unit 56, and provides the output enable signal OE2 in the OEB form to the scan unit 54. Therefore, the scan unit 54 starts to operate according to the start wave STVB, the gate clock signal CPV, and the output enable signal OE2 in the OEB form. The scan unit 56 also starts to operate according to the start wave STVD, the gate clock signal CPV, and the output enable signal OE4 in the OED form.

As the start waves STVD and STVB will be transferred in the gate driver 401, the pixels indirectly coupled to each scan line will reset data after a predetermined time from starting to load the display data. Moreover, it can be known from the aforementioned new panel architecture and new driving method that each sub-data line is not required to change the polarity in a same frame, and only needs to write the reset data once in a period T (as shown in FIG. 6). Therefore, both the image data and the reset data can effectively utilize the limited charging time. In addition, as the output enable signals in the OED form and the OEB form assume the logic low level at different time points, the problem of loading wrong data into the pixels will not occur. In other words, the pixels that receive the display data will not receive the reset data RST, and the pixels that receive the reset data RST will not receive the display data.

Then, FIG. 7 will be described below to illustrate the method for controlling the scan lines of the present invention more clearly. FIG. 7 is a schematic view of the method for controlling the scan lines according to an embodiment of the present invention, showing the signal forms of the output enable signals received by the scan units 53-56 in a frame A. It is shown clearly in this figure that after the gate driver 401 receives the start wave STVD, the scan units 53-56 will receive the output enable signals in the OED form in a period of time, and each of the scan units will receive the start wave STVB after receiving the start wave STVD for a predetermined time Tbk.

The polarity control timing of FIG. 8 may be obtained according to the operation method of FIG. 6. FIG. 8 is a schematic view of a method for controlling polarities of data during the operation of the circuit of FIG. 4, in which POL1 and POL2 are polarity control signals of the source drivers 402 and 403, respectively. In this figure, the polarity is changed at two positions, namely, the time point when an (n−1)th frame is shifted to an (n)th frame, marked by 801, indicating that the polarity of the display data must be changed at this time point, and the time point when an (n−1)th reset frame is shifted to an (n)th reset frame, marked by 802, indicating that the polarity of the reset data must be changed at this time. As the output polarities of the sub-data lines have been designed and planned when the panel architecture is established, the impulse system can be realized as long as a column inversion operation is performed on the display data or the reset data in the time of a same frame, and the scan line control method shown in FIG. 7 is used as well. Thus, both the display data and the reset data can achieve the best image quality of dot inversion.

In view of the spirit of the embodiment described above, another display panel architecture can also be used to implement the driving method of the present invention, which is shown in FIG. 9. FIG. 9 shows another embodiment of the display panel of FIG. 3, and shows the coupling relationship between the internal components of another display panel 304 and the timing controller 303, and the image signal DATA2 and the plurality of control signals CS sent to the display panel 304 by the timing controller 303. Referring to FIGS. 4 and 9, the difference between the architecture of the two display panels is that the pixels are coupled in a 2-line inversion manner in FIG. 9. Taking the first four pixels in the column as shown in FIG. 9 for example, the pixel 904 is coupled to the sub-data line D₁ and the scan line G63₁, the pixel 905 is coupled to the sub-data line D_1′ and the scan line G63₂, the pixel 906 is coupled to the sub-data line D₁ and the scan line G63₃, and the pixel 907 is coupled to the sub-data line D₁ and the scan line G63₄. The coupling relationship of other pixels is similar to the above description. Moreover, in the gate driver 901, each scan unit is responsible for driving 8 rows of scan lines. For example, the scan unit 63 is responsible for driving the scan lines G63₁-G63₈.

FIG. 10 is a schematic view of the data reorganization method according to the embodiment of FIGS. 3 and 9. In FIG. 10, DE1 is a data enable signal corresponding to the input image signal DATA1, DE2 is a data enable signal corresponding to the image signal DATA2, CPV is the above gate clock signal, and OED and OEB are two signal forms of each of the output enable signals (OE1-OE4). The input image signal DATA1 has a plurality of image segments. Each of the image segments has the display data of the pixels coupled to two adjacent scan lines. For example, the image segment 1001 has the display data of the pixels coupled to the scan lines G63₁ and G63₂, and the image segment 1002 has the display data of the pixels coupled to the scan lines G63₃ and G63₄.

Referring to FIGS. 5 and 10 together, it is known from the comparison between the figures that the data reorganization method of FIG. 10 defines four image segments as one group, and inserts a reset data RST into each group of image segments. Thus, a time segment Tcycle originally having four batches of data is changed to have five batches of data, and the reset data RST is arranged after the image segments of each group. Therefore, the aforementioned arithmetic unit 301 must generate the positions to arrange the reset data RST according to such a counting relation.

FIG. 11 is a timing diagram of a part of signals of the circuit in FIG. 9, and shows the timing of the gate clock signal CPV, the two forms of output enable signals (OED and OEB), the gate start driving signal STV, and gate pulse signals between the scan lines. The gate start driving signals STV also has two start waves, which are denoted by STVD and STVB, respectively. Referring to FIGS. 6 and 11 together, it is known from the comparison between the two figures that the timing of FIG. 11 is to drive the scan lines coupled to each of the scan units in four batches, and drives 8 rows of scan lines at the same time when the reset data is written.

The polarity control timing of FIG. 12 may be obtained according to the operation method of FIG. 11. FIG. 12 is a schematic view of the method for controlling of polarities of data during the operation of the circuit of FIG. 9, in which POL1 and POL2 are polarity control signals of the source drivers 402 and 403 respectively. In this figure, the polarity is also changed at two positions, namely the time point when an (n−1)th frame is shifted to an (n)th frame, marked by 1201, indicating that the polarity of the display data must be changed at this time, and the time point when an (n−1)th reset frame is shifted to an (n)th reset frame, marked by 1202, indicating that the polarity of the reset data must be changed at this time.

Persons skilled in the art should understand that a single source driver can also be used to drive the data lines as shown in FIG. 13, in addition to using two source drivers to drive the data lines with as described in the above embodiments. FIG. 13 shows yet another embodiment of the display panel of FIG. 3. The coupling manner of the pixels in a pixel matrix 1301 can be the same as the architecture of FIG. 4 or FIG. 9. Likewise, each scan unit of the gate driver 1302 is responsible for driving B scan lines, where B is a positive integer. However, the source driver 1303 is responsible for driving all of the sub-data lines, i.e., D₁-D_N and D_1′-D_N′. No matter the coupling manner of the pixels of FIG. 13 uses the architecture of FIG. 4 or FIG. 9 or not, the above driving method can be utilized, which will not be described herein again.

Though the display panel having 16×N, 32×N or B×N pixels is taken as an example in the above embodiments, users should understand that the present invention can also be implemented if the display panel includes M×N pixels. Here, M is also a positive integer, and B<M. In addition, it is not limited to define every two or every four image segments as one group, users can define every K image segments as a group freely, where K is a positive integer.

Basic processes of the operation can be concluded according to the teaching of the above embodiments, as shown in FIG. 14. FIG. 14 is a schematic view of the processes of the method for driving a display panel according to an embodiment of the present invention. First, an input image signal is provided (Step 1401). Next, the input image signal is divided into a plurality of image segments, and each of the image segments has display data of pixels coupled to two adjacent scan lines (Step 1402). Then, every K image segments are defined as a group (Step 1403). After that, a reset data is inserted into each group of the image segments (Step 1404). Then, the scan lines corresponding to a first group are driven in K batches according to the first start wave, and the two adjacent scan lines are driven each time. When the two adjacent scan lines are driven, display data of the pixels coupled to the (i)th scan line among the scan lines that have been driven is provided to the first sub-data lines, and display data of the pixels coupled to the (i+1)th scan line among the scan lines that have been driven is provided to the second sub-data lines (Step 1405). Afterwards, after a predetermined time from the first start wave, the scan lines corresponding to the first group are driven at the same time according to a second start wave, and the reset data is output to the first sub-data lines and the second sub-data lines (Step 1406).

To sum up, the present invention adopts a special display panel, in which each column of the data line includes two sub-data lines. Moreover, the present invention divides the input image signal into a plurality of image segments, and each of the image segments has display data of pixels coupled to two adjacent scan lines. Next, every K image segments are defined as a group, and a reset data is inserted into each group of the image segments, so as to form an image signal. After that, display data of a first group are written in K batches according to the first start wave. After a predetermined time from the first start wave, the scan lines corresponding to the first group are driven at the same time according to a second start wave, and the reset data is output to the first sub-data lines and the second sub-data lines. Thus, the present invention can provide double frame rate, and can effectively eliminate motion blur. In addition, as the polarities of the sub-data lines do not change in a frame, the present invention can reset the data of the pixels of several adjacent scan lines at the same time.

It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention.
