Method and device for adjusting conformity of spliced wall

Abstract

The embodiment of the invention discloses a method and device for adjusting the conformity of a spliced wall, which are used for automatically adjusting the conformity of brightness and chromaticity of the entire wall after a light source of the spliced wall is changed. The spliced wall is formed by splicing a plurality of display units. The method comprises the following steps of: detecting the light source characteristic parameters of one display unit; and adjusting the light source characteristic parameters of the display unit when the difference between the light source characteristic parameters and the preset light source characteristic parameters of the display unit meets preset conditions.

Description

technical field [0001] The invention relates to the technical field of splicing wall display, in particular to a method and device for adjusting the consistency of a splicing wall. Background technique [0002] With the development of computer technology, splicing wall, as a branch of professional display technology, is more and more widely used; the splicing wall is more flexible to build, and can choose different video processing systems according to the user's requirements for input signals, so as to meet different use occasions , different signal input requirements; also through the control software, various signal switching, splicing into full-screen display, arbitrary combination display, etc. can be realized. [0003] However, after a long time of use, the light source of the video wall will experience brightness attenuation. When the brightness attenuation reaches the factory-defined ratio of the light source itself, it can be considered that the light source has rea...

Problems solved by technology

[0003] However, after a long time of use, the light source of the splicing wall will experience brightness attenuation. When the brightness attenuation reaches the factory-defined ratio of the light source itself, it can be considered that the light source has reached the maximum life. At this time, the light source of the display unit of the splicing wall needs to be replaced

In the prior art, after replacing the light source of the display unit, due to the individual differences in the brightness and chromaticity of the light source of the display unit, the consistency of brightness and chromaticity of the entire wall of the splicing wall will change. At this time, it is necessary to manually adjust the consistency of the splicing wall However, the consistency adjustment of the splicing wall requires professional technicians to operate, and the requirements for personnel are high, and the workload of consistency adjustment is relatively large, which also increases the difficulty of light source replacement.
