Automatic adjusting system and correcting method for color and brightness consistency of spliced large screen

Abstract

The invention provides an automatic adjusting system and a correcting method for the color and brightness consistency of a spliced large screen. The automatic adjusting system for the color and brightness consistency of a spliced large screen comprises a special camera which is erected in front of the spliced large screen; a color brightness correction module which is used for receiving an image collected by the special camera, of each large screen unit, calculating the brightness difference and the color difference of each splicing unit, and calculating the correction parameters; an RS232 interface which is used for sending the correction parameters to each large screen unit; a color brightness adjustment module which is arranged in each large screen unit, and used for adjusting the colorand the brightness of each large screen unit according to the correction parameters. According to the spliced large screen color and brightness consistency automatic adjustment system and the correction method, the brightness difference and the color difference of the spliced screen can be corrected at the same time, so that the color consistency effect of the spliced wall is well improved.

Description

technical field [0001] The invention relates to a system and a correction method for automatically adjusting the color brightness consistency of spliced ​​large screens, belonging to the field of display. Background technique [0002] The application of splicing large screens is becoming more and more extensive, and the application fields include military applications and command systems, police and public security systems, government management and public service systems, traffic management and radio and television communications, exhibition and planning application systems, energy applications and resources systems, commercial and enterprise application systems, etc., and have developed into a wide range of commercial fields. Therefore, its market share is very large, and most users require 7*24 hours, 365 days of uninterrupted operation. Therefore, the requirements for its display effect are very high.

AI Technical Summary

Problems solved by technology

[0003] In the selection of various types of splicing large screens, due to the difference in the manufacturing process of each splicing display unit, the brightness and color effects of the screens will vary.

When displaying the splicing screen, the screen at the junction of the splicing screen has a large visual difference in color and brightness

[0004] In addition to the differences in the factory, after a certain period of operation of the splicing large screen that has been installed, debugged and delivered to the user, due to the difference in attenuation of the equipment, differences in brightness and color will inevitably occur between the screens, and professional engineers are required to adjust the differences in the screens. To complete, so the splicing screen manufacturers generally need to send people to door-to-door service, which greatly increases the service operation cost of the enterprise

Not only that, after the warranty period, users need to pay extra to ask the splicing screen manufacturer to provide door-to-door service, which greatly increases the maintenance cost of users
