Abstract

The embodiment of the invention discloses a method and a display device for adjusting the color and brightness of a display device. The method in the embodiment of the present invention includes: obtaining the adjustment value input by the user through a touch screen, wherein the adjustment value includes at least a rough adjustment value, and the adjustment value at least includes: decimal adjustment value, tenth place adjustment value, and percentile adjustment value Any one or any combination of the numerical value, and the adjusted numerical value of the thousandth place, or the adjusted numerical value of the Nth digit after the decimal point; wherein, N is an integer greater than 3; and the display image is adjusted according to the obtained adjusted numerical value. By triggering the screen, the adjustment value input by the user is obtained. The value includes not only the coarse adjustment value, but also the fine adjustment value. The display device adjusts the displayed image according to the coarse adjustment value and the fine adjustment value. Since multiple decimal places can be adjusted Make adjustments to make the adjustment of the display device more accurate, and make the brightness of the video wall look consistent more quickly and conveniently.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a method and a display device for adjusting the color and brightness of a display device. Background technique [0002] Display devices can be seen everywhere in the urban environment, and usually a large display device is spliced ​​by multiple small display devices, such as: a display splicing wall. In order to make the picture displayed on the display splicing wall natural and harmonious, it is necessary for the display brightness of each display on the display splicing wall to be consistent. In order to achieve consistent brightness and color of each display on the splicing wall, the prior art adopts an on-screen menu (OSD, On-Screen display) adjustment method to adjust the brightness and color of each display. [0003] Due to the OSD modulation method, generally through the button on the display or the menu key on the infrared remote control, and then display ...
