Embodiment Construction

[0020] The structure and working process of the present invention will be further described below.

[0021] An intelligent automatic adjustment system for an LED display, comprising a controller, a light sensor, a current regulation module, a current detection device, and an LED display module. The brightness information of the screen is sent to the controller. The current detection device is used to obtain the current value of the constant current pin of the drive chip. The current adjustment module, the current detection device and the constant current pin of the LED display drive chip are connected in series in sequence. The current regulation module, light sensor, and current detection device are all connected to the controller. The controller adjusts the adjustable resistance value according to the brightness information of the LED display and the current value of the constant current pin of the driver chip, and adjusts the white balance of the LED display in real time. p...

Abstract

The invention discloses an intelligent and automatic adjustment system for an LED display screen. The system comprises a controller, a light sensor, a current adjusting module, a current detection device and an LED display screen module. The light sensor is arranged to the front end of the LED display screen module and is used for obtaining brightness information of the LED display screen and sending the information to the controller; the current detection device is used for obtaining the current value of a constant current pin of a driver chip; and the controller adjusts the value of an adjustable resistor according to the brightness information of the LED display screen and the current value of the constant current pin of the driver chip, and thus white balance parameters of the LED display screen are adjusted in real time. The brightness information of the LED display screen is obtained through the light sensor in real time, and the current value of the constant current pin of the driver chip is obtained, and white balance of the display screen is adjusted automatically according to the brightness information, the current value of the constant current pin and the preset brightness value, thereby effectively improving work efficiency and accuracy of the white balance.

Description

technical field [0001] The invention belongs to the application field of electronic products, and in particular relates to an intelligent automatic adjustment system of an LED display screen. Background technique [0002] The white balance effect is one of the most important indicators of the display. In terms of color science, when the ratio of the three primary colors of red, green and blue is 1:4.6:0.16, pure white will be displayed. If there is a slight deviation in the actual ratio, there will be a deviation in white balance. Generally, it is necessary to pay attention to whether the white is blue or yellowish. green phenomenon. The quality of the white balance is mainly determined by the control system of the display screen, and the die also affects the reproduction of the color. [0003] In the brightness adjustment of the LED display, if the ratio of the three primary colors of red, green and blue is 1:4.6:0.16, the forward current deviation will be too large, resu...
