Patent ID: 7893919

Claim:
A pixel having a bit depth, the pixel comprising: a plurality of substantially equally sized display elements each having an “on” position and an “off” position, wherein the display elements each emit visible light when in the “on” position, the plurality of substantially equally sized display elements includes a first group of display elements and a second group of display elements, the display elements of the first group each controlled by n 1 bits of a driver signal and having an intensity of a predetermined value when in the “on” position and the display elements of the second group each controlled by n 2 bits of the driver signal and having an intensity of a fraction of the predetermined value when in the “on” position, an intensity of the pixel being equal to an intensity of each of the plurality of display elements in the “on” position; wherein the pixel is configured such that the first group of display elements provide a brighter output level than that of the second group of display elements, the quantity n 1 being less than the quantity n 2 such that the bit depth of the pixel comprises a coarse gradation of shade provided by the first group of display elements and a finer gradation of shade provided by the second group of display elements.
