Abstract

The invention provides a driving chip anomaly detection method and device, electronic equipment and a readable storage medium. The method comprises the steps: inputting a link training signal into a first driving chip in N driving chips connected in series through a first pin of a time sequence controller; when it is detected that the first pin is at a first level and the duration exceeds first preset time, determining that a detection mode is started; sequentially inputting a link training signal to each target driving chip in the N driving chips in the detection mode, and obtaining the levelof the first pin again when a link control signal is input to the target driving chip; and when the level of the first pin is the first level, determining that the target driving chip is abnormal. According to the invention, each driving chip is detected through the time sequence controller, the abnormal information of the driving chip is obtained, and the abnormal information is displayed in thedisplay screen at the corresponding position of the normal driving chip, so that the abnormal reason is quickly and correctly determined.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a driving chip abnormality detection method, device, electronic equipment and readable storage medium. Background technique [0002] In the existing large-size liquid crystal display panel (Liquid Crystal Display, LCD), there are unit modules such as timing controllers, driver chips, and power chips that are independent of each other. When the electronic equipment is in the lighting process, individual driver chips will burn out. , but it is impossible to know the faulty driver chip, and it is necessary to return the defective product to the factory for analysis before confirming the faulty driver chip. Contents of the invention [0003] The invention provides a drive chip abnormality detection method, device, electronic equipment and readable storage medium to solve the problem that the faulty drive chip cannot be known when the electronic equipment fails. [0004] A...
