However, this method is only a compromise method, and it cannot achieve the best effect on the screen display; or, when the screen displays images with different brightness, the color temperature data used is the same, so that different brightness cannot be guaranteed. The brightness of the picture shows the best effect

Embodiment

[0045] see figure 1 , figure 1 It is a schematic flowchart of the visual display calibration method of the all-in-one screen GAMMA in the embodiment of the present invention.

[0046] like figure 1 Shown, a kind of all-in-one machine screen GAMMA visual display calibration method, described method comprises:

[0047] S11: Adjust the HDMI signal output by the computer received by the screen of the all-in-one machine to a white picture, and adjust the color temperature of the white picture to a preset color temperature;

[0048] In the specific implementation process of the present invention, the adjusting the color temperature of the white picture to the preset color temperature includes: setting the display screen of the all-in-one machine to the preset color temperature that needs to be achieved; and, based on the screen of the all-in-one machine The adjustment main board adjusts the color temperature parameter, and adjusts the color temperature of the white screen to a pr...

Abstract

The invention discloses a visual display calibration method, device and system for an all-in-one machine screen GAMMA. The method comprises the following steps: adjusting an HDMI signal outputted by acomputer and received by the all-in-one machine screen into a white image, and adjusting the color temperature of the white image to a preset color temperature; presetting HDMI signals output by thecomputer as different brightness mode signals, and reading color coordinate values of a current picture of the screen of the all-in-one machine based on a color analyzer; dividing the X axis of the all-in-one machine screen GAMMA into 16 equal parts, and obtaining corresponding optimal value points of the all-in-one machine screen GAMMA under different brightness mode signals; according to the X-axis data of the optimal value point, respectively adjusting the corresponding RGB values to enable the color temperature of the current picture to meet a preset color temperature requirement and formthree three-primary color curves; and carrying out smoothing processing on the three formed three-primary-color curves to obtain three smooth three-primary-color curves. According to the embodiment ofthe invention, pictures displayed by the screen of the all-in-one machine under different brightness can be guaranteed to display the optimal effect.

Description

technical field [0001] The technical field of screen display calibration related to the present invention, in particular, relates to a visual display calibration method, device and system of an all-in-one machine screen GAMMA. Background technique [0002] Due to some characteristics of LCD screens, even the screens of the same batch will have differences in picture performance, mainly reflected in the difference in color temperature when displaying different brightness; the current common practice is to adjust the color temperature as much as possible. Value, so that the color temperature difference of the screen with different brightness is not too big. However, this method is only a compromise method, and it cannot achieve the best effect on the screen display; or, when the screen displays images with different brightness, the color temperature data used is the same, so that different brightness cannot be guaranteed. Brightness screens are shown with the best results. ...
