Embodiment Construction

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some preferred embodiments of the present invention, not all of them. . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0028] In addition, when the present invention only describes the structure and composition scheme related to the solution of the technical problem, although there is no description below for the known necessary structure, parts and connection relationship, it does not mean that the technical scheme does not exist, let alone should be insufficient grounds for disclosure.

[0029] refer to figure 1 , the basic hardware architecture of the system o...

Abstract

The invention discloses an LED display screen module correction data automatic loading method which is characterized in that the method comprises the steps that a hot-plugging detection circuit detects whether there is a module be replaced, if yes, a receiving card reads the ID of the module and carries out checking; and when the ID of the module is inconsistent with the ID stored in the receiving card, the receiving card reads chroma correction data stored on the module and carries out verification, the chroma correction data passing the verification is stored in the receiving card and/or is loaded, and otherwise the receiving card generates brightness compensation data corresponding to the module and loads the brightness compensation data. In the working process of a display screen, re-powering is not needed for the replacement of the module, an automatic identification module loads the chroma correction data, and a plug-and-play function is realized; in addition, the modules incorrect in correction data are automatically identified, the correction data thereof are abandoned, the bad influences of the absence of chroma correction are reduced by the brightness compensation, and a significant effect is obtained.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to a method and system for automatically loading calibration data of LED display screen modules. Background technique [0002] With the advancement of science and technology, LED display applications are becoming more and more popular. For high-end applications (such as concerts, TV stations, etc.), there are very high requirements for display effects and on-site fault processing speed. In order to ensure the display effect of the display screen, improve the display consistency and color reproduction of the screen, make the screen more delicate, lifelike, and the color closer to the original color of the display content, it is necessary to perform chromaticity correction on the display screen. If the module fails and needs to be replaced with a new module, if the calibration of the new module does not match other modules, it will seriously affect the display effect. In a...
