Embodiment Construction
[0017] see figure 1 , is a schematic block diagram of the detection system of the GOA circuit of the present invention. Such as figure 1 As shown, the detection system 1 of the GOA circuit of the present invention includes a configuration unit 11, which is used to read the standard timing of the clock signal of the GOA circuit and the phase relationship between each clock signal from the microcontroller and store it;
[0018] The detection unit 12 is connected to the configuration unit 11, and is used to detect the timing of the clock signal actually output by the GOA circuit and compare the timing of each clock signal with the standard timing in the configuration unit 11 and judge whether it is consistent;
[0019] The processing unit 13 is connected to the detection unit 12. When the detection unit 12 detects that the timing of the clock signal actually output by the GOA circuit is inconsistent with the standard timing in the configuration unit 11, the processing unit 13 ob...

The invention discloses a detection method and system for a GOA circuit and electronic equipment. The method comprises the steps: reading a standard time sequence of clock signals of the GOA circuit and the phase relation between the clock signals, and storing the standard time sequence and the phase relation; detecting the time sequences, which are actually outputted by the GOA circuit, of the clock signals, comparing the time sequence of each clock signal with the standard time sequence, and determining whether the time sequence of each clock signal is consistent with the standard time sequence or not; and outputting the standard time sequence when the time sequences, which are actually outputted by the GOA circuit, of the clock signals are not consistent with the standard time sequence.The method solves a problem that the disorder time sequence of a display panel causes a black screen in a static environment or when a signal is not stable, and improves the stability of the displaypanel.
Description
technical field [0001] The invention relates to the field of GOA circuit detection, in particular to a GOA circuit detection method, system and electronic equipment. Background technique [0002] When the GOA (Gate Drive On Array) circuit in the existing display panel is in a static environment or the signal source is unstable, it is easy to cause a short-term GOA circuit timing disorder, which makes the GOA circuit disorder, resulting in the overcurrent protection of the level converter, and the occurrence of The display panel goes black for a short time. Contents of the invention [0003] The invention mainly provides a detection method, system and electronic equipment of a GOA circuit, aiming at solving the current problem of a black screen of a display panel caused by a timing disorder of a GOA circuit. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is to provide a detection method of a GOA ci...
