Color temperature compensating method

Abstract

The invention relates to a color temperature compensating method which comprises the following steps: judging the component strength of three colors in an input three-dimensional color signal; when the three colors have the same component strength, executing a lookup mechanism to find out a first group of multi-primary color signals corresponding to the three colors with the same component strength, and carrying out digital gamma correction on the first group of multi-primary color signals so as to provide a first group of color temperature compensating signals; when the three colors are different in the component strength, executing the lookup mechanism to find out a second group of multi-primary color signals corresponding to the three colors with different components, and carrying out digital gamma correction on the second group of multi-primary color signals so as to provide a second group of color temperature compensating signals; and enabling the three colors with the same component and at least one same color with the same component among the three colors with different components to be different in the brightness displayed on a multi-primary color display.

Description

technical field [0001] The invention relates to a color temperature compensation technology, in particular to a color temperature compensation method of a multi-primary color display and its application. Background technique [0002] In recent years, with the vigorous development of semiconductor technology, portable electronic products and flat panel display products are also emerging. Among the types of flat panel displays, liquid crystal displays (LCDs) have become the mainstream of display products due to their advantages of low voltage operation, no radiation scattering, light weight and small size. [0003] Nowadays, in order to further increase the color gamut range of the liquid crystal display, a multi-primary color display has been developed. Unlike previous three-primary-color displays that use red (Red, R), green (Green, G), and blue (Blue, B) to achieve color mixing effects, multi-primary color displays use four or more colors to achieve color mixing. , so tha...

[0005] However, since the blue gamma curve (blue gamma curve) reflected by the reduced blue component will be too different from the standard gamma curve (standard gamma curve (such as gamma 2.2) to be displayed), so that the multi-primary color Most of the images displayed on the monitor after color temperature compensation will have insufficient blue (that is, the blue component will be distorted), so that the multi-primary color monitor after color temperature compensation will have "color shift (color shift)" question
