Embodiment Construction

[0028] Please refer to Figure 4 . Figure 4 It is a schematic diagram of the first embodiment of the method for improving the liquid crystal display by the black insertion technology of the present invention. Figure 4 In Figure A with image 3 The picture in A is the same: the brightness of the pixel is 2 in the picture 1-3. Figure 4 Picture B in middle is for comparison Figure 4 The pixel data in Figure A and the brightness diagram of the pixel when using the black insertion technology of the present invention: the brightness of this pixel is 2 in the first half period of picture 1, and 1 in the second half period; the brightness of this pixel is 2 in the first half period of picture 2, and the brightness in the second half period is 2 The period is 1; the brightness of this pixel is 2 in the first half period of picture 3, and is 1 in the second half period. It can be seen that the black insertion technology of the present invention inserts the original picture in the ...

Abstract

A display method improves a liquid crystal display by means of black frame insertion technology; the display method includes receiving an image gray-scale data stream; generating a first image brightness data stream according to the gray-scale data stream of the image and a first Gamma curve; generating a second image brightness data stream according to the gray-scale data stream and a second Gamma curve of the image; sequentially inserting data in the second image brightness data stream to the first image brightness data stream to generate a third image brightness data stream; providing the third image brightness data stream for a liquid crystal display to display the image.

Description

technical field [0001] The present invention relates to a method for improving the display of a liquid crystal display by black insertion technology, more precisely, the present invention relates to a method for improving display of a liquid crystal display by black insertion technology based on a Gamma curve. Background technique [0002] Please refer to figure 1 . figure 1 It is a schematic diagram showing the difference between a cathode ray tube display (Cathode Ray Tube, CRT) and a liquid crystal display (Liquid Crystal Display, LCD). figure 1 Figure A is a schematic diagram of cathode ray tube display imaging; figure 1 Figure B is a schematic diagram of liquid crystal display imaging. Assuming that a pixel in the cathode ray tube display is selected, the gray scale value of this pixel is 30 and the corresponding brightness is 3 in screen 1, and the gray scale value of this pixel is 20 and the corresponding brightness is 2 in screen 2. In screen 3, the grayscale val...
