Problems solved by technology

However, this method of only relying on the personal experience of the tester to make adjustments is easy to cause errors
Moreover, this adjustment method cannot obtain accurate adjustment standards, and it is very likely that different results will be adjusted due to different testers or in different environments.

Embodiment Construction

[0023] In order to enable the examiner to better understand the technical content of the present invention, preferred specific embodiments are described as follows.

[0024] Please refer first figure 1 The structure diagram of the color signal processing device of the present invention.

[0025] The color signal processing device 10 of the present invention is used to measure and adjust the color signal emitted by the display 41 so that the display 41 can display the best color signal. The display 41 is a screen with a three primary color signal generating module 42 which in this embodiment includes a red signal generating module 42R, a green signal generating module 42G, and a blue signal generating module 42B. The display values ​​stored by the various color signal generation modules in the three primary color signal generation module 42 can be used to directly control the color display of the display 41.

[0026] The color signal processing device 10 includes a main control mo...

Abstract

The invention provides a method and a device for processing color signals. The method for processing color signals is used for the device for processing color signals so as to regulate a tricolor signal generating module of a display. The method comprises the following steps: inputting test signals into the display; retrieving an original color signal of the display; judging whether the original color signal is in an ideal color signal predetermined range or not; if the original color signal is not in an ideal color signal predetermined range, fixing one color signal generating module in the tricolor signal generating module and regulating another two color signal generating modules of the tricolor signal generating module.

Description

Technical field [0001] The invention relates to a color signal adjustment method, in particular to an automatic color signal adjustment method. Background technique [0002] With the development of science and technology and the improvement of living standards, modern people have higher and higher requirements for displays, especially paying more attention to the performance of the display in the color signal. However, in the current display manufacturing process, even if the same manufacturing process is used and the same type of substrate is used, the display produced by the same input signal may have different color performance. The reason may be that the characteristics of each electronic component material used to manufacture the display are different. Therefore, the adjustment of the display color is an important link in the current display manufacturing process. [0003] In the prior art manufacturing process, a tester usually observes the color performance of the display ...
