ABSTRACT:
A gray scale display method includes converting the binary code of conventional picture data into an optimal code, based on display system characteristics. Gray levels of an image to be displayed are error-diffused and displayed using frame rate modulation. In order to reduce the likelihood of saturation of the gray levels, the maximum value of data displayed according to the optimal code is greater than or equal to the maximum value of the picture data displayed according to a conventional binary code. In addition, the number of adjacent gray levels is minimized. As a result, the driving voltage for driving electrodes in a display device and picture cross talk are reduced.
