Problems solved by technology

According to the traditional method, if one gamma curve is used for all screen modules of the same model, there will also be large differences in color temperature on flat-panel TVs, which will not only affect the subjective effect of the TV, but also affect the sales of the TV.
If the color temperature consistency of the screen module is improved through the components used in the front-end control screen module, it means that the cost will increase significantly

Embodiment

[0018] Such as figure 1 , 2 As shown, the method for improving the color temperature consistency of flat-panel TVs by using multiple gamma curves includes the following steps:

[0019] a. Determine the color temperature range of the screen modules used in flat-panel TVs, and preferably use screen modules with large differences in color temperature between individuals to determine the color temperature range.

[0020] b. Classifying the color temperature ranges of the screen modules;

[0021] c. Perform gamma debugging on the screen module samples in each color temperature level, so that the color temperature after debugging is within the required color temperature range;

[0022] d. Merge the corresponding debugged gamma curve into the TV software;

[0023] e. Test to determine the color temperature level of each screen module on the production line, select the corresponding gamma curve in the TV software, and complete subsequent production.

[0024] Next, take a 50-inch s...

Abstract

The invention discloses a method for improving the color temperature consistency of flat-panel TVs by using a plurality of gamma curves, and relates to the field of flat-panel TV flat-screen modules. The method includes the following steps: determining the color temperature range of the screen module used by the flat-panel TV; classifying the color temperature range of the screen module; performing gamma debugging on the screen module samples in each color temperature class, so that The color temperature after debugging is within the required color temperature range; integrate the corresponding debugged gamma curve into the TV software; test to determine the color temperature level of each screen module on the production line, select the corresponding gamma curve in the TV software, and complete subsequent production. The present invention does not increase any cost on the existing flat-panel TV and screen module, so that after the flat-panel TV with the same type of screen module is produced, the displayed color temperature is controlled within the required range, which improves the consistency of color temperature. sex.

Description

technical field [0001] The invention relates to the field of flat-panel TV flat-screen modules, in particular to a method for improving the color temperature consistency of flat-panel TVs by using a plurality of gamma curves. Background technique [0002] As competition in the flat-panel TV market intensifies, in order to reduce costs, various manufacturers have caused large differences in color temperature among screen modules of the same type. According to the traditional method, if one gamma curve is used for all screen modules of the same model, there will be large color temperature differences on flat-panel TVs, which will not only affect the subjective effect of the TV, but also affect the sales of the TV. If the color temperature consistency of the screen module is improved through the components used in the front-end control screen module, it means that the cost will increase significantly. Contents of the invention [0003] The object of the present invention is ...
