Abstract

The present invention provides a detection circuit of a display panel and a detection method of the circuit. The detection circuit includes: two detection lines, respectively used to provide scanning signals to each row of pixel units; one of the detection lines is only connected to the one scanning line of the pixel unit, and the other detection line is connected to another scanning line of the pixel unit. In the detection circuit of the display panel and the detection method for the display panel using the circuit of the present invention, the abnormality of the display panel is detected by connecting two scanning lines of the pixel unit to different detection lines and applying different voltages respectively, The technical problem that the prior art cannot detect the abnormality of the display panel is solved, so as to improve the display effect.

Description

technical field [0001] The invention relates to the field of displays, in particular to a detection circuit of a display panel and a method for using the detection circuit to detect the display panel. Background technique [0002] Existing display panels include a plurality of pixel units, and each pixel unit includes a main pixel unit and a sub-pixel unit. In order to solve the problem of large viewing angle deviation, the brightness of the main pixel unit is usually set to be greater than the brightness of the sub-pixel unit, thereby improving display effect. The main pixel portion has a first thin film transistor, and the sub-pixel portion has a second thin film transistor and a third thin film transistor. The main scanning line is connected to the control terminals of the first thin film transistor and the second thin film transistor. When the input of the main scanning line is at a high level, the first thin film transistor and the second thin film transistor are close...
