Multi-gray level display apparatus and method of displaying an image at many gray levels |
摘要 |
A multi-gray level display designed to display multi-gray level images free of flicker or the like, by using a small number of voltages. The display comprises a first gray-level pattern generating circuit 311 for generating a first gray-level pattern which acquires a gray level during m frame periods, a second gray-level pattern generating circuit 321 for generating a second gray-level pattern which acquires another gray level during n frame periods (n is a positive integer greater than m), and a selection circuit 341 for selecting and outputting one of the preset voltages, in accordance with an output from the first gray-level pattern generating circuit 311 or the second gray-level pattern generating circuit 321 when the input multi-gray level display data corresponds to a gray level of either the first gray-level pattern or the second gray-level pattern.
