An automatic point-by-point adjustment control system

Abstract

The invention discloses an automatic point-to-point adjustment and control system comprising an image acquisition unit, a transmitter, a brightness acquisition unit, a processing unit and an adjusting unit. The image acquisition unit is connected with the transmitter to automatically acquire the image data of an external LED (Light Emitting Diode) display screen, the brightness acquisition unit is fixed on the LED display screen to automatically collect the whole brightness data of the LED display screen, the processing unit is provided with a receiver matched with the transmitter, a processing module and a distributing module, the receiver is used for receiving the image data and transmitting the image data to the processing module, the processing module is used for generating adjusting data according to the image data and the brightness data and transmitting the adjusting data to the adjusting unit, and the adjusting unit comprises a plurality of adjusting modules for respectively adjusting the brightness of various LED pixel points in the LED display screen. The automatic point-to-point adjustment and control system can be used for adjusting automatically in real time so that the adjusted LED display screen is always in an active condition with uniform and good display effect.

Description

technical field [0001] The invention relates to the control technology of lighting devices, in particular to an automatic point-by-point adjustment control system. Background technique [0002] With the application of LED displays more and more widely, users have higher and higher requirements for the uniformity of the display brightness of LED displays. Optical characteristics, and the LED display is affected by various factors during the production and installation process, which cannot guarantee the uniform brightness of the LED display after the installation is completed, and the LED display needs to be replaced or rebuilt after aging. Lights, and even screen replacement, these processes require a lot of manpower and capital. [0003] In the prior art, various LED brightness point-by-point adjustment technologies are based on human-made operation methods, that is, each step requires human operation to complete.

[0002] With the application of LED displays more and more widely, users have higher and higher requirements for the uniformity of the display brightness of LED displays. Optical characteristics, and the LED display is affected by various factors during the production and installation process, which cannot guarantee the uniform brightness of the LED display after the installation is completed, and the LED display needs to be replaced or rebuilt after aging. Lights, and even screen replacement, these processes require a lot of manpower and capital

[0003] In the prior art, various LED brightness point-by-point adjustment technologies are based on human-made operation methods, that is, each step requires human operation to complete. In this way, each step requires people to operate and analyze, and requires professionals, which wastes manpower and material resources, and increases the cost. Moreover, due to the point-by-point adjustment technology in the prior art, uneven brightness appears on each LED display screen. Therefore, the LED display cannot be kept in a display state with uniform brightness, which will easily affect the display effect.
