Problems solved by technology

This kind of scheme is an automatic correction method to a certain extent. It is a relatively effective method for the LED display screen set up on site, but it must rely on imaging equipment. Due to the unavoidable measurement errors and calculation accuracy, This solution has some limitations; moreover, if the uniformity of the LED display itself is good, especially

Embodiment Construction

[0023] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] See figure 1 A splicing bright and dark line compensation method suitable for LED display screens provided by an embodiment of the present invention includes steps S101, S103, S105, S107 and S109, specifically as follows:

[0025] Step S101: Obtain position information and resolution information of multiple physical splicing units of the target display screen. Specifically, take the LED box as an example of a physical splicing unit; usually, the LED box is connected to the display control card at the front end (such as the sending card in the synchronous control system) and is equipped with one or more LED light boards and receiving cards. Reading the parameters on the front-end display control card and receiving card can obtai...

Abstract

The invention relates to a splicing bright and dark line compensation method and a related compensation device applicable to LED displays, comprising the following steps: (a) acquiring location information and resolution information of multiple physical splicing units of a target display; (b) drawing a distribution map of multiple virtual splicing units according to the location information and resolution information, wherein the multiple virtual splicing units and the multiple physical splicing units are in one-to-one correspondence relationship; (c) marking the boundary region of each virtual splicing unit in the distribution map; (d) selecting a target boundary region in the distribution map; and (e) adjusting the brightness of the edge pixels of the physical splicing unit corresponding to the target boundary region to a target brightness in order to compensate the splicing bright and dark lines of the target display. Therefore, the problem that splicing bright and dark line adjustment takes a long time and the problem that on-site splicing bright and dark line positioning is difficult can be solved.

Description

technical field [0001] The invention relates to the technical field of display control, in particular to a splicing bright and dark line compensation method and a splicing bright and dark line compensation device. Background technique [0002] LED display is a flat panel display device composed of LED dot matrix. With the rapid development of this industry, LED display is widely used in various occasions of daily life. The reason why LED display is widely used and developed rapidly is inseparable from its own advantages. These advantages include: high brightness, low working voltage, low power consumption, free assembly, large screen, long life , low failure rate, impact resistance, stable performance, high visibility, and easy matching with integrated circuits. Based on semiconductor technology that has been booming for decades, LED display has a series of advantages such as adjustable brightness range, safety and environmental protection, energy saving, bright color, larg...
