Embodiment Construction

[0019] The present invention is described in detail below in conjunction with accompanying drawing:

[0020] The LED display screen state detection method comprises the following steps:

[0021] 1] Form a detection loop

[0022] 1.1] Connect the light boards of each sub-unit of the LED display in groups, and set detection sensors in each sub-unit; the group connection specifically refers to the selected LED point light source on each light board and the selected LED point light source on the adjacent light board. The LED point light source connection, the connection can choose to connect any horizontal row on the light board and the LED point light source on the adjacent light board in series, or choose to connect the LED point light source on the adjacent light board in series, or choose a point connection at random, and at the same time, between the LED point light sources The connection between them can be connected by cable or in other ways. The core purpose of this step ...

Abstract

The invention provides a method for detecting a state of a light emitting diode (LED) display screen, and mainly solves the problems of low detection precision and incomprehensive detection of the conventional detection method and the problem that the conventional detection method cannot be used for detecting a flat cable and a single point. By the method for detecting the state of the LED display screen, flat cable connection and the working state of the single point of the LED display screen can be effectively and quickly detected, and the LED display screen can be quickly positioned. All the steps of the LED display screen can be monitored; and the maintenance time is greatly saved.

Description

technical field [0001] The invention belongs to an LED display screen detection method, in particular to a LED display screen state detection method. Background technique [0002] The structure of the LED display is complex, the working environment is harsh, and the probability of failure is high. In order to make the LED display screen play normally, it is necessary to monitor the working status of the LED display screen. The existing detection method is to adopt various troubleshooting methods to determine the cause of the problem after the display screen has a problem. However, due to the complex structure of the LED display screen, there are many reasons why the display screen cannot work normally. A lot of time will be wasted, and if it is due to insufficient technical capabilities or troubleshooting errors, the problem will become more and more serious. Contents of the invention [0003] The invention provides a method for detecting the state of an LED display scre...
