Abstract

The application discloses a GOA circuit over-current protection detection circuit, the over-current protection detection method thereof and an electronic device; the GOA circuit over-current protection detection circuit comprises a logic control module and a level shift module; a special picture is used as a preset signal in advance, current data and pixel data of the special picture are stored into a logic control module; whether the input signal is consistent with the preset signal or not is judged through comparison, and different overcurrent protection parameters are adopted according to the judgment result, so that the phenomenon of false triggering of GOA circuit overcurrent protection under a special picture can be prevented, and the effect of overcurrent protection of a liquid crystal display panel is achieved on the basis of preventing false triggering.

Description

technical field [0001] The present application relates to the display field, in particular to a GOA circuit overcurrent protection detection circuit, its overcurrent protection detection method and an electronic device. Background technique [0002] At present, with the maturity of the gate on array (GOA) circuit on the array substrate and its advantages in cost and structure, most of the liquid crystal display panels have been transformed into the GOA structure. However, in the actual mass production application, in the production process, some GOA line defects and abnormal internal impedance of the line will appear, which will cause the liquid crystal display panel to generate high current and heat during operation, so as to melt the glass and cause fire safety accidents. happened. [0003] Therefore, in order to avoid the above-mentioned problems, currently used GOA-based liquid crystal display panels generally use an over-current protection (Over Current Protection, OCP...
