Embodiment Construction

[0035] A LED display system and its method for correcting bright and dark lines provided in this specific embodiment are as follows: figure 2 shown. The LED display system also includes four parts: LED display, bright and dark line display data acquisition equipment, bright and dark line correction coefficient calculation unit, and LED display control unit.

[0036] When the LED display system works:

[0037] First of all, turn on the white screen, which is to light up the LED display and make the LED display completely white;

[0038] Then carry out the bright and dark line data acquisition, namely obtain the imaging information at the splicing gap between each LED display module on the LED display screen through the bright and dark line display data acquisition device;

[0039] Then perform the calculation of the bright and dark line correction coefficient, that is, the bright and dark line correction coefficient calculation unit calculates the bright and dark line correc...

Abstract

The invention discloses an LED display screen system and a rectifying method for bright and dark lines thereof. The system comprises an LED display screen, an LED display control unit, a bright and dark line display data collecting device used for collecting bright and dark line display data from the LED display screen and generating bright and dark line imaging information, and a bright and dark line rectifying coefficient calculating unit used for calculating bright and dark line rectifying coefficient according to the bright and dark line imaging information. The method comprises the steps of hitting a white screen, collecting the bright and dark line data, calculating the bright and dark line rectifying coefficients and rectifying the bright and dark lines. The LED display system adopting the bright and dark line rectifying method of the LED display screen system is accurate in rectification due to the fact that optical imaging information is used as a basis, and can avoid bright and dark line adjusting mistakes caused by visual errors. Bright and dark line rectifying coefficient software is used for automatically calculating the bright and dark line rectifying coefficient, and a bright and dark line rectifying algorithm is utilized, so that calculation precision is high. Bright and dark line rectifying documents are generated according to modules, so that management is convenient. The technology has special timeliness and flexibility when used for rented LED display screens and arc-shaped LED display screens.

Description

technical field [0001] The invention relates to the technical field of LED display, in particular to an LED display screen system and a method for adjusting bright and dark lines thereof. Background technique [0002] In the current LED display system, the system structure for realizing full-screen point-by-point correction is as follows: figure 1 As shown, the system includes four parts: LED display screen, display data acquisition, correction coefficient calculation, and LED display control. When the system is working, the imaging information of the LED display is obtained through the display data acquisition device, the correction coefficient is calculated from the imaging information and a correction file is generated, and then the correction file is output to each light point of the LED display through the LED display control system, thereby Realize point-by-point correction of LED display. [0003] Since LED display screens are usually spliced ​​by several LED displa...
