LED Display Panel Grayscale Modulation Based on Computer Calculation

Abstract:

In order to improve the method of the LED display panel grayscale modulation, a method based on computer calculation is proposed. First, the development history and trends of the LED display panel are introduced. Second, present the structure of the LED display panel and the existed modulation method. Simultaneously, point out the ground for shortcomings of the existed method. Third, describe the principle modulation method based on computer calculation detail from two steps, which are the data signal transformation and the grayscale modulation. Forth, describe the realization steps of this method in accordance with the third step. Finally, this method is supplied in a LED display panel, whose resolution is 320×240. Experimental results show that this method is able to increase the grayscale from 14-bit to 16-bit, and can enhance the display result of the LED display panel significantly.
