Compared with the prior art, the computer display brightness controller can automatically control the brightness of a display according to light changes, can adjust the required brightness by means of the potentiometers as needed, is convenient to use and has the value of popularization and application.

Description

technical field [0001] The invention relates to a computer hardware technology, in particular to a computer display brightness controller. Background technique [0002] A computer, commonly known as a computer, is a modern electronic computing machine used for high-speed computing. It can perform numerical calculations, logical calculations, and has storage and memory functions. It is a modern intelligent electronic device that can run according to the program and process massive data automatically and at high speed. In the prior art, the display of a computer cannot be seen clearly due to light changes during use, and it is cumbersome to adjust the brightness of the display according to light changes. Therefore, there is room for improvement. Contents of the invention [0003] The object of the present invention is to provide a computer display brightness controller in order to solve the above problems. [0004] The present invention achieves the above object through th...
