Abstract:
Instant invention is related to a method to display gray shades in RMS responding display matrix, comprising acts of: selecting each row of the display matrix with a set of 's' discrete select voltages in a sequence or random and applying a set of discrete data voltages to a column of the display matrix wherein the data voltages are of both polarities and energy of the select and data waveforms that are applied to rows and columns are constants during the 's' time intervals for all the rows and columns to display gray shades in RMS responding display matrix.
Abstract:
A driver (106) for driving pixels (104) of a display (102), wherein the pixels are divided into a first group and a second group and the driver is constructed for supplying a first drive signal to a first pixel and a second drive signal to a second pixel, the first and second pixels being neighboring pixels. The driver (106) comprises means for generating a first upper value and a first lower value; and means for generating a second upper value and a second lower value. It comprises means for driving, in a first operating mode, the first pixel withthe first lower value and driving the second pixel with the second upper value. In a second operating mode, driving the first pixel with the first upper value and driving the second pixel with the second lower value. Means (108) for controlling the operating mode alternates between the first operating mode and the second operating mode.

Abstract:
A method, device and computer program are detailed for modulating write light. For a plurality of pixel locations of an electro-optic layer of an optical write valve and across each of a plurality of consecutive frames, a set of pixel data bits is modulated across a first (102) and a second pulse width period (103) of the frame. The first and second pulse width periods, and adjacent pulse periods of sequential frames, are separated from one another by a pulse-off (104)that is at least equal to a response time of the electro-optic layer during which no bits are modulated. Separately in each frame, write light is output from each of the plurality of pixel locations according to the modulated pixel data bits in the frame. In an embodiment, the set of pixel data bits are modulated by applying a volatage at a pixel location of the electro-optic layer in synchronism with illuminating a light source that illuminates that pixel location.

Abstract:
Waveforms for driving electro-optic displays, especially bistable electro-optic displays, are modified by one or more of insertion of at least one balanced pulse pair into a base waveform; excision of at least one balanced pulse pair from the base waveform; and insertion of at least one period of zero voltage into the base waveform. Such modifications permit fine control of gray levels.
Abstract:
In one embodiment, a display system includes a subpixelated display panel and a backlight array of individually controllable multi-color light emitters. When the display panel comprises a multi-primary subpixel arrangement having a white (clear) subpixel, the backlight control techniques allows the white subpixel to function as a saturated primary display color. In another embodiment, the display system may calculate a set of virtual primaries for a given image and process the image using a novel field sequential control employing the virtual primaries. In another embodiment, a display system comprises a segmented backlight comprising: a plurality of N + M light guides, said light guides forming a N x M intersections; a plurality of N + M individually addressable light emitter units, each of said N + M light emitter unit being associated with and optically connected to one of said N + M light guide respectively.
