Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0037] like figure 1 As shown, the memory of the display system is used to store the white balance debugging program. When each screen is output, the CPU will read the data from the memory, convert it into adjusted screen data, and display it on the display module. Since different display screens store different data, each display screen can only be matched with the memory on the display device after adjustment, and cannot be stored in the display screen in a portable ma...

Abstract

The invention relates to the technical field of display screens, in particular to a display screen white balance adjusting method and system. The system comprises a display system and a to-be-debuggeddisplay screen module, an optical probe used for acquiring brightness and color coordinate data of the display system; a debugging board used for outputting gray-scale picture information of which the gray-scale values are increased progressively to the display system according to an instruction of the test computer; and the test computer used for controlling the optical probe to obtain the optical parameter value, completing the operation of the chromaticity coordinate and outputting an instruction to the debugging board according to the operation result. By adopting the technical scheme provided by the invention, the technical problems that an existing display screen white balance adjusting method cannot adapt to various display screens, the adjusting precision is poor and the gamma value of the display screen can be changed are solved.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to a method and system for adjusting the white balance of a display screen. Background technique [0002] With the gradual development of technology, more and more scenes need white balance. For example, the color coordinates of car instrument and central control navigation need to be similar and more beautiful. For example, when displaying a white screen, some LCD displays are warmer (yellowish) and some are cooler (bluer). In order to restore color authenticity and reflect the color of the object itself, white balance adjustment is required. [0003] like figure 1 As shown, the main method at present is: use the memory of the display system to store the white balance debugging program. When each screen is output, the CPU will read the data from the memory, convert it into the adjusted screen data, and send it to the display module for display. . [0004] Since different...
