Reducing the distance between the hinge points (12) to zero would result in a single hinge ‘book’ type of the display system. However the calculation of the unfixed display length would still hold.
In the other extreme situation one could (theoretically) align the hinge points with the fixation points—in other words reduce the distance to the hinge points (11) to zero.
Due to the linear relationship between these extremes situations the upshot of these considerations is that the hinge points need to lie on the dotted lines a, b indicated in
13=(2*11+12)/2
In accordance with the invention, by allowing one of the fixed parts of the display to slide, the position of the hinge points can be shifted.
In a first embodiment of the invention schematically shown in

It is observed that this embodiment with the two slider elements 10 can also be configured without the fixation 9a of the segment 2a so that the display is only connected with the slider elements 10. Such a configuration has the advantage of an easy mounting of the display in the housing, whereas in the display itself a smooth transition exists between the parts supported by the slider elements and the non-supported parts of the segment 2a.

The display system in accordance with the invention provides a way to assemble a flexible display in a housing, leaving one degree of freedom for movement of the display in the housing. Basically the invention allows one (or more) of the ‘fixation’ point(s) of the display to move relative to the hinge while closing the housing. Essentially this reduces during closing the excess display length that needs to be compensated for.
An advantage of the invention is that the design freedom for the display system is much larger and not limited by the prior limited position of the hinge axis (or axes in case of double hinges).
A second advantage is that the display in open situation of the system can be pre-stretched by the spring (or spring means) 12 or 32, located in the connection between the slider element and the housing, thus preventing the sagging of the display segment 2a, 2b, 2c respectively in the hinge area in the open situation. Because of this pre-stretching, the display will also be more able to withstand touching with less deformation.
In accordance with the invention the spring force biased mechanism—i.e. the slider or sliders 10 cooperating with the spring or springs 12 of
Finally due to the increased space available in the hinge area more space is available for a “touch support” mechanism such as described in U.S. application No. 61/506,177, filed Jul. 11, 2011. Such a “touch support” for the display segment 2a in combination with the pre-stretching of the display by the spring 12 may be advantageous for the life time of the display, especially in the gaps between the different display supports of the display system, where no support is available.
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.
