Abstract

The present invention relates to the technical field of display control. The invention, in order to solve the problem that the conventional TV screen brightness and contrast debugging lacks a unifiedstandard, provides a TV screen brightness and contrast automatic debugging system and method. The method comprises introducing a self-made debugging signal into a signal generator; enabling a controlmodule to switch debugging signals; and enabling the control module to complete the reading-writing control of a register parameter corresponding to the TV brightness and contrast according to a brightness value collected by a brightness meter, thereby completing the debugging of the TV brightness and contrast, realizing the quantification of the TV brightness and contrast debugging, and improvingthe picture quality of the whole TV. In addition, the control module automatically debugs the brightness and contrast to improve debugging efficiency. The system and method are suitable for out-of-factory TV brightness and contrast debugging.

Description

technical field [0001] The invention relates to the technical field of display control, in particular to a debugging system and method for brightness and contrast of a TV picture. Background technique [0002] In the product development stage, digital TVs need brightness and contrast debugging, that is, to determine the parameter values ​​of the corresponding registers when the brightness and contrast in the user menu are in the maximum, standard and minimum states, and write the parameter values ​​into the registers. At present, most of them use the naked eye to observe the brightness and contrast of the screen, and manually adjust the register to debug the brightness and contrast of the TV screen. Due to the subjective factors of the debugger, different debuggers have different judgments on the brightness and contrast. As a result, there are large differences in the brightness and contrast of multiple TVs, lack of uniform standards, and the efficiency of manual debugging i...
