Abstract
A method for improving the display effect of colors of a liquid crystal display (LCD) by mapping of a color range belongs to the field of information technology and comprises the following steps: firstly, the LCD and a cathode ray tube display are connected with a computer, and the computer is turned on; secondly, the two displays are regulated by a colorimeter, and meanwhile, rectangular color lumps in different colors are inputted into the displays and simultaneously displayed on the two displays; thirdly, the scopes of the color ranges of the displays are measured by the colorimeter, and a coordinate figure of a peak of the color range is obtained; and fourthly, the coordinate of the peak of the color range of the LCD is mapped to the coordinate of the peak of the color range of the cathode ray tube display by the mapping method of the color range; if picture effects are same, the improved display effect of the color of the picture of the LCD is obtained, and a matrix circuit is added in the LCD; and if the picture effects are different, the operation returns to the third step, and the scopes of the color ranges of the displays are measured again until the picture effects of the LCD and the cathode ray tube display are same.
Description
Technical field
The present invention relates to a kind ofly improve the method for display effect of colors of liquid crystal display (LCD), belong to areas of information technology by Color Gamut Mapping.
Background technology
Compare with traditional cathode-ray picture tube display,, still lagging behind the cathode-ray picture tube display aspect color representation and the saturation degree though LCD has advantages such as high-resolution, small size.The cathode-ray picture tube display can more perfect display image under any resolution, and theoretically, can show unlimited color.As everyone knows, the figure place of display is high more, and the shown color of display is just many more, and color is abundant more, and the quality of picture is good more.LCD is easy to generate the distortion of pixel when being in high-resolution, display effect is caused certain influence, and the number of colours that shows relatively is limited with cathode-ray picture tube, though some LCD declares to reach 32 colors, but all realize also having gap with 32 real looks by dither algorithm.Improve the color restoration capability of LCD, reproduce perfect color and show to have stronger realistic meaning.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides a kind of method of improving display effect of colors of liquid crystal display (LCD) by Color Gamut Mapping.
A kind of device that improves display effect of colors of liquid crystal display (LCD) by Color Gamut Mapping, comprise chromascope, computing machine, LCD, cathode-ray picture tube display, LCD is connected with computing machine with chromascope respectively with the cathode-ray picture tube display.
Described LCD is the BENQ7T4 LCD.
Described cathode-ray picture tube display is ViewSonic's 747 cathode-ray picture tube displays.
A kind ofly improve the method for display effect of colors of liquid crystal display (LCD) by Color Gamut Mapping, method is as follows:
1) LCD is connected on computers start with the cathode-ray picture tube display;
2) with chromascope two kinds of displays are proofreaied and correct, imported the rectangular color lumps of different colours simultaneously to display, and on two kinds of displays, show simultaneously;
3), obtain the coordinate figure on colour gamut summit with the gamut range of chromascope mensuration display;
4) the colour gamut apex coordinate of LCD is mapped to the colour gamut apex coordinate of cathode-ray picture tube display by the method for Color Gamut Mapping, if image effect unanimity, the color display effect of the LCD image after improving increases a matrix circuit in LCD; If image effect is inconsistent, return step 3), redeterminate the gamut range of display, consistent until LCD with cathode-ray picture tube display image effect.
The described matrix circuit of step 4) is integrated circuit 89C51, is connected on the display circuit of LCD.
