The present application discloses a detection method of a display panel and a display panel. The detection method is used to detect abnormal points on a data line or a scan line of the display panel. The detection method includes the steps of: recording the start time , and open the scan lines and data lines in the display panel in a preset order; detect whether a preset abnormality occurs, and if a preset abnormality occurs, record the intersection of the current scan line and the current data line as the abnormal point, and record the current The time is the abnormal time; the position of the abnormal point is calculated according to the start time, the preset sequence and the abnormal time; wherein, the abnormal point includes a short circuit point and a break point. Open the scan line and data line according to the preset sequence, and calculate the position of the abnormal point according to the start time, preset sequence and abnormal time, which is very convenient, simple and fast.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a detection method of a display panel and the display panel. Background technique [0002] With the wide application of display panels, people have higher and higher requirements for the display of display panels. In order to improve the yield of display panels, inspections are often carried out before shipment or during the preparation process to eliminate existing problems and ensure the quality of the products sold. The quality of the display panel improves the customer experience effect. [0003] At present, some abnormalities on the panel, such as foreign objects or broken wires, will be checked with a microscope, but it needs to be checked one by one, which takes a lot of time, and the verification affects production efficiency. Some abnormal points inside the chip cannot be checked out through a microscope. Contents of the invention [0004] The purpose of t...
