Patent ID: 8054277

Claim:
A display device, comprising: a display panel comprising a plurality of pixels arranged in a matrix; a brightness identification unit configured for identifying a brightness of an image element to be displayed by at least one pixel from the plurality of pixels, wherein the brightness of the image element is determined by a corresponding primary display signal; a polarity analyzing unit configured for analyzing a result of the identification, and for generating a composed binary signal, the composed binary signal having a first binary portion the same as the primary display signal and an additive second binary portion; and a data circuit configured to provide a data voltage to drive the at least one pixel according to the composed binary signal; wherein a value of the data voltage is determined by the first binary portion of the composed binary signal, and a polarity of the at least one pixel is determined by the second binary portion of the composed binary signal, the second binary portion is determined by a combination of the result of the identification and a location of a corresponding pixel where the primary display signal is to be applied.
