Abstract:
1. An electro-optical device, comprising: a matrix of pixel elements; a matrix of pixel drivers, each of which corresponds to one of the pixel elements; and a matrix of element processors, each of which corresponds to one of the pixel drivers executing grayscale calculation for transforming the grayscale resolution of the pixel data into another grayscale resolution, which is intrinsic in the couple of the pixel element and the driver, with reference to error distributed from the adjacent element processors in order to supply the result of the calculation to the corresponding pixel driver, and also to distribute the error of the grayscale calculation to the adjacent pixel element processors, superior layers of a matrix of element processors providing the element processors with pixel data, which is fed to each of the element processors of the matrix, and element processors on an edge of the matrix using constant values in substitute for error distributed from the adjacent processors.
