Embodiment 1

[0049] figure 2 It is a schematic flowchart of a white balance adjustment method for a display system provided in Embodiment 1 of the present invention, see figure 2 , the white balance adjustment method of this display system in the embodiment of the present invention includes:

[0050] Step S210, running the white balance test unit integrated in the display system;

[0051] Step S220, using the white balance test unit to read the test-specific atlas stored in the display system to perform a white balance test, so as to adjust the white balance parameters of the display system to meet the preset range;

[0052] Step S230, updating the adjusted white balance parameters to all signal input channels of the display system.

[0053] go through figure 2In the steps shown, run the white balance test unit integrated in the display system, use the white balance test unit to read the test pattern play test in the display system, and adjust the white balance parameters under a sig...

Embodiment 2

[0073] The invention also provides a display system. Figure 4 It is a structural block diagram of a display system provided in Embodiment 2 of the present invention, see Figure 4 , the display system 400 includes:

[0074] a storage unit 410, configured to store the atlas for white balance testing;

[0075] The white balance test unit 420 is used to read the test spectrum stored in the storage unit 410 to perform a white balance test, so as to adjust the white balance parameters of the display system to meet the preset range;

Abstract

The invention discloses a white balance adjustment method of a display system and a display system. The white balance adjustment method comprises steps of operating a white balance test module integrated in the display system; reading a test special map stored in the display system using a white balance test unit for performing a white balance test, so as to adjust white balance parameters of the display system to be within a preset range; and updating and sending the adjusted white balance parameters to all signal input channels of the display system. The technical scheme of the invention is characterized in that testing is achieved through the white balance test unit integrated in the display system during white balance adjustment, so as to replace a test computer system; and the white balance test unit is used to directly control the map required in play for adjusting white balance, and a test special signal generator is replaced in map generation, so that the cost of white balance adjustment is reduced, and the stability of white balance adjustment is improved.

Description

technical field [0001] The invention relates to the technical field of display systems, in particular to a white balance adjustment method of a display system and a display system. Background technique [0002] With the continuous development of display technology, people have higher and higher requirements for the picture quality displayed by the display system. White balance is an important part of the image quality adjustment of the display system. The display effect played a crucial role. As an important parameter of display technology, white balance can solve a series of display problems such as color reproduction and tone processing by adjusting white balance. The emergence of automatic white balance adjustment method makes white balance adjustment easier and easier. figure 1 It is a schematic diagram of a white balance test system in the prior art; see figure 1 At present, during the white balance test, it is necessary to generate a test-specific map through a sign...
