LED screen dead pixel monitoring and early warning method and system

Abstract

The invention discloses an LED screen dead pixel monitoring and early warning method and system. The method comprises the following steps: a. setting the standard characteristic value of the dead pixel amount of a target LED display screen; b. detecting the display data of each pixel point of the target LED display screen; c. according to the display data, calculating the practical characteristic value of the dead pixel amount; d. comparing the practical characteristic value with the standard characteristic value; when the practical characteristic value is more than the standard characteristic value, outputting a comparison result; and e. according to the comparison result, generating early warning signal data, and giving out early warning. The system is correspondingly provided with a detection unit, a control unit, an early warning unit and a regulation unit. When the practical characteristic value of the dead pixel amount of the target LED display screen exceeds the preset standard characteristic value, the invention gives out early warning so as to ensure lower replacement difficulty and lower replacement and maintenance cost.

Description

technical field [0001] The invention relates to a lighting device, in particular to a method and system for monitoring and early warning of dead pixels of an LED screen. Background technique [0002] With the development of LED display technology, LED display applications and LED lighting applications have become more and more widely used in various lighting applications due to their low energy consumption, strong color reproduction, long life, huge size, and unique shapes. Occasions, especially large-scale LED displays, are more important in major occasions or worldwide activities. [0003] In the prior art, there are a variety of fault detection schemes, which can detect and display minor faults that occur on LED displays, including LED dead pixels. However, generally in large-scale LED displays, due to the relatively large area of ​​the LED display, Occasionally, one or two bad pixels have no obvious impact on the visual effect of the entire LED display screen, so they c...

Problems solved by technology

[0003] In the prior art, there are a variety of fault detection schemes, which can detect and display minor faults that occur on LED displays, including LED dead pixels. However, generally in large-scale LED displays, due to the relatively large area of ​​the LED display, Occasionally, one or two bad pixels have no obvious impact on the visual effect of the entire LED display screen, so they can be ignored. Only when the number of dead pixels exceeds a certain value, will it affect the overall visual effect of the LED display , so it is necessary to replace the module where each bad pixel pixel is located. If all the modules where all LED dead pixels are located are replaced, the difficulty of replacement will be increased, and the cost of replacement and maintenance will be higher.
