This application is a divisional of U.S. application Ser. No. 12/690,708, filed Jan. 20, 2010 and entitled “ELECTRONIC DEVICE WITH AT LEAST ONE EXTENDABLE DISPLAY SECTION,” the entire disclosure of which is hereby incorporated by reference.
The invention relates to an electronic device with at least one extendable display section.
The present invention relates to the field of electronic devices with a flexible display. Presently flexible displays can be made with a curvature radius in the range of 5 to 10 mm thus providing a rollable or wrappable display. This makes it possible to store a flexible display or part of it in a compact space, for instance for transportation or when otherwise not needed. A typical use of these displays is in mobile products. Any such display integrated into a device will need to be supported by an extension mechanism when rolled or folded out, to ensure flatness or even tautness and protection of the display.
The flexible displays in electronic devices of the kind disclosed in WO 2006-126158 A1 normally have two modes of use. The first is a compact mode, which can be used for transportation and summarized information viewing (for instance as a preview screen). The second mode is a maximum mode, which can be used for extensive reading/viewing of the large display. When using a wide screen or large (≧7-inch) flexible display a large stroke needs to be initiated to switch between the two positions. The mechanisms required for this quickly become either very large (in closed state) or have little rigidity (in open state).
In accordance with embodiments of the present invention a wide screen flexible display is used in an electronic device with a compact closed state and one or more open states in which an end position is fixed and at least part of the display is flat.
According to one aspect, the exemplary embodiments provide an electronic device comprising a display with at least one extendable display section and a further display section. The electronic device also includes a main body including a body area supporting part of the display, electronics of the device, and electrical and mechanical connections of the display. Moreover, a hold out mechanism is provided that supports the extendable display section. The display is movable with respect to the main body between a normal position, where the display is fully located in or adjacent to the body, and an extended position, where the extendable display section extends outwardly from the body area. In the extended position the extendable display section is supported by the hold out mechanism.
Furthermore, the display includes at least two extendable sections. Each of the extendable sections is movable to an extended position and supported by an associated hold out mechanism. The respective extendable sections extend outwardly from the main body from different sides of the body area and form one continuous display panel with the further display section.
According to another aspect, the described exemplary embodiments provide an electronic device comprising a flexible display with at least one extendable display section and a further display section. The electronic device also includes a main body including a body area supporting part of the display, electronics of the device, and electrical and mechanical connections of the display. Moreover, the devices in accordance with illustrative embodiments include a hold out mechanism for supporting the extended part of the extendable display section. Moreover, the display is movable with respect to the main body between a normal position, where the display is fully located in or adjacent to the body, and an extended position, where the extended part of the extendable display section extends outwardly from the body area, supported by the hold out mechanism. The extendable display section and the further display section are supported by two parts of the main body that are pivotally connected between an open and closed position of the display. In the open position the extendable display section, with its extended part, and the further display section together form one continuous display panel.
While the appended claims set forth the features of the present invention with particularity, the invention, together with its objects and advantages, may be best understood from the following detailed description taken in conjunction with the accompanying drawings of which:
As shown in
The main body 2 forms a housing for electronics of the device. It supports the display and is used for those parts of the display which have no or limited flexibility, such as the display drivers and display connections 13. The main body 2 has a rigid area with user interface buttons 10.
Since each mechanism 3, 4 needs to support only part of the display panel, it can be made compact and stiff. In the closed position (

A wrap mechanism of the kind of wrap mechanism 16 is described in more detail in publication WO 2006/085271, published Aug. 17, 2006 which is expressly incorporated in this application by reference in its entirety. It is noted that the two hold-out mechanisms may operate separate from each other, but it may be advantageous to have them operating synchronously.

In the different embodiments the display panel 9 at the area of the front cover 5 or parts of the display panel or the whole display itself can be used as a touch screen for user interface purposes. In all embodiments in every position and mode of use the display is operated by a visible touch-sensitive area. This allows multiple user interface scenarios depending on which mode of use the user has chosen. The display that is supported in the body area or when using embodiment 2 or 6 also in the slide area and embodiment 3 in the wrap area makes it possible to use touch sensitivity in several ways; either integrated in the display itself, by using a flexible or rigid front cover or by implementing a touch sensitive area beneath the display.
The advantages of the device 1 in accordance with the illustrative embodiments give users the opportunity to use the device in three or more different states. A large wide screen display can be implemented (display ≧7 inches) while still keeping the device portable like a mobile phone. Having the main body 2 in the middle of the device provides support for the display and other rigid parts (including user interface, touch screen, display drivers, display flexes and hold out mechanisms) can be implemented here, resulting in a more rigid device.
The detailed drawings, specific examples and particular formulations given, serve the purpose of illustration only. Furthermore, other substitutions, modifications, changes, and omissions may be made in the design, operating conditions, and arrangement of the exemplary embodiments without departing from the scope of the invention as expressed in the appended claims.
