DISPLAY

摘要

A display comprises independently addressable pixels, a pixel comprising first and second electrodes (12a,12b) disposed on a first substrate and spaced apart from one another. A counter electrode (22) is provided on a second substrate, with an electro-optical material provided between the first substrate and the second substrate. A controller, in use, applies a first voltage to the first electrode of the pixel, a second voltage different to the first voltage to the second electrode of the pixel, and a third voltage to the counter electrode of the pixel to define in the pixel at least one of a first region (18a), a second region (18c) and a third region (18b). The first, second and third voltages are selected such that the area of the or each of the first, second region and third region defined in the pixel produces a desired greyscale level for the pixel.

1. A display comprising:
a first substrate; a second substrate spaced from the first substrate; an image display layer disposed between the first substrate and the second substrate and comprising an electro-optical material, the electro-optical material not being a ferro-electric electro-optical material; and a controller; wherein the display comprises a plurality of independently addressable pixels, a pixel of the plurality of pixels comprising:
a first electrode and a second electrode disposed on the first substrate, the first electrode being spaced from the second electrode in a direction parallel to the plane of the first substrate;a resistive layer disposed on the first substrate and electrically connected to the first electrode and to the second electrode; andanother electrode disposed on the second substrate; the controller, in a first mode, being adapted to, for a pixel of the display, apply a first voltage to the first electrode of the pixel, apply a second voltage different to the first voltage to the second electrode of the pixel and apply a third voltage to the another electrode of the pixel to define in the pixel at least one of a first region in which the electro-optical material is in an unswitched state, a second region in which the electro-optical material is in a fully switched state and a third region in which the electro-optical material is in a partially switched state, the first, second and third voltages being selected such that the area of the or each of the first region, second region and third region defined in the pixel produces a desired greyscale level for the pixel.
