According to the invention a first conductor pattern (8) for driving said display area (2) and a second conductor pattern (9) for tansmitting signals from said electrically controlled input 5 device (3) are arranged on said first substrate. The invention also relates to a method for manufacturing such a display device.
摘要:
A gray level compensation mechanism is proposed for flexible displays. Flexible displays exhibit cell gap variations upon bending. The cell gap is measured during operation of the display (capacitive, poezoelectric). The pixel voltage is adjusted according to the measured cell gap. This results in a gray level that is independent of the local bending radius.

The present invention provides for improved image quality in bendable liquid crystal displays (400). In such displays the liquid crystal layer (401) is contained in a cell gap having a thickness which decreases when the display is bent. For displays based on swithcable retardation, such as TN (Twisted Nematic) or STN (Super Twisted Nematic) displays, this has as a consequence that the cell retardation value decreases, such that optical properties as colour, contrast and viewing angle become less good. The inventions therefore proposes to compensate for this effect with a compensating film (407) or coating of having a retardation which changes as a function of stress induces in the layer when the display is bent and thereby compensates the retardation changes of the liquid crystal (401) such that the total retardation (cell+compensator) stays constant
摘要:
A system comprises a display (1) with a substrate (16) and a carrier (2). The display (1) comprises pixels (11) and display conductors (12) which supply display signals (DS) to the pixels (11). The carrier (2) comprises carrier conductors (20) for carrying input signals (IS). The display conductors (12) and the carrier conductors (20) are positioned with respect to each other to obtain capacitors (C) between corresponding ones of the display conductors (12) and the carrier conductors (20) to capacitively transfer the input signals (IS) on the carrier conductors (20) to the display conductors (12).
摘要:
An apparatus comprising a first cell (10b), said first cell comprising a plurality of first elements (34b), said first elements being controllable between a non-reflective state, in which electromagnetic radiation having a first polarization is reflected to a first extent, and a reflective state, in which said electromagnetic radiation having a first polarization is reflected to a second extent, said second extent being greater than said first extent. Said apparatus further comprises a second cell (10a), superimposed on the first cell, said second cell comprising a plurality of second elements (34a), said second elements being controllable between a non-reflective state, in which electromagnetic radiation having a second polarization is reflected to a third extent, and a reflective state, in which said electromagnetic radiation having a second polarization is reflected to a fourth extent, said fourth extent being greater than said third extent. Said first and second elements are arranged so that said first polarization is different from said second polarization.
摘要:
A display device comprising at least one substrate, a first and a second electrode, a display medium and an optically active layer, wherein said optically active layer comprises a polarizer and is arranged between said substrate and said display medium, and wherein said substrate is made of a birefringent material.
摘要:
Using lithographic spacers (6) and seals (12) in e.g. LCD a first adhesion of the substrates (2,3) is obtained by incomplete solidifying (both physical or chemical) of the resin used for the spacers and/or the polyimide used for the seal. Final solidifying of the spacers may take place during solidifying of the seal afterwards or simultaneously.
摘要:
This invention relates to a method of manufacturing a curved flat panel display device, comprising the step of adhering, at least a first film (1, 11) to the surface of a second film (2, 12), in such a way that the films (1, 11; 2, 12) are held in a curved shape by means of the adhesion between the films (1, 11; 2, 12). The invention also relates to a curved flat panel display device, comprising at least a first and a second film, characterised in that the first and second films are adhered to each other, whereby the adhesion between said films is arranged to hold the display device in a curved shape.
