Abstract

The embodiment of the invention provides a brightness adjusting device and a method thereof and a display, which belong to the technical field of liquid crystal display, and by which the automatic adjustment of the brightness of a display screen can be realized simultaneously according to the brightness of the surrounding environment of the display screen and the distance between an eyeball of a user and the center of the display screen, thereby improving the accuracy of brightness adjustment of the screen of a display device, and increasing the display efficiency of the display. The brightness adjusting device comprises a distance acquisition device, a brightness measuring device and a brightness adjusting device, wherein the distance acquisition device is connected with the first end of the brightness adjusting device; the brightness measuring device is connected with the second end of the brightness adjusting device; the distance acquisition device is used for acquiring the distance between an eyeball of a user and the center of a display screen of a display device; the brightness measuring device is used for acquiring the brightness value of the external environment of the display screen of the display device; and the brightness adjusting device is used for adjusting the brightness of the display screen of the display device according to the distance between the eyeball of the user and the center of the display screen of the display device and the brightness value of the external environment of the display screen of the display device.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a brightness adjustment device, a method thereof and a display. Background technique [0002] Displays currently on the market have a fixed brightness when displaying pictures. When the human body is close to the display and needs to be dimmed or is far away from the display and needs to be brightened, it usually needs to be adjusted and set manually, which brings inconvenience to the user. Great inconvenience. [0003] In order to realize the automatic adjustment of the brightness of the display, the prior art discloses a technology capable of automatically adjusting the brightness of the display according to the brightness of the environment. However, when the surrounding environment is dark, the brightness of the display is relatively dark, but when the user is far away from the display, the brightness of the display will be too dark, and even the screen cannot...
