Problems solved by technology

[0012] First, in the manufacturing process, the time to adjust the white balance will occupy a considerable proportion, which will increase the time of the manufacturing process and lead to a decrease in production efficiency
[0013] Second, due to the use of fixed color coordinates that have nothing to do with the country or region, the quality of the product image is lowered for the product user. In order to supplement this, it is necessary to add a white balance adjustment operation, which brings inconvenience to the user.

Abstract

The display white balance adjustment device comprises: a counter to control R / G / B contrast according to external gain, a memory to store at least one color coordinate information, and a controller to adjust the white balance according to user selected reference. This invention reduces total process time, improves production efficiency, and is very convenient for application.

Description

technical field [0001] The present invention relates to the invention of the display, and more specifically relates to the invention of the white balance adjustment device and method of the display. Background technique [0002] On an image device such as a monitor that displays a color image, white balance adjustment is necessary in order to correctly display and adjust the color image in a timely manner. [0003] Therefore, in the display manufacturing process, there must be a white balance adjustment process. The configuration and operation of a conventional white balance adjustment device will be described with reference to FIG. 1 . [0004] A display white balance adjustment device according to the prior art is shown in FIG. 1 , which includes a display 10 , a color coordinate measuring device 13 and an operating device 15 . Wherein the display 10 compares the color coordinates provided by the outside with the standard color coordinates to adjust the white balance; th...
