Abstract

The present invention provides a detection drive circuit for display detection of a liquid crystal display panel, which includes a first GOA circuit, a second GOA circuit and a detection signal input circuit. The detection signal input circuit generates the driving signals of the first scanning line in the first order, and the detection signal input circuit generates the driving signals of the second scanning line in the second order; the order of the first order and the second order are opposite. The invention also provides a detection driving device and a detection method. The present invention improves the accuracy of display performance detection of the liquid crystal display panel by driving the first scanning line and the second scanning line in reverse order.

Description

technical field [0001] The invention relates to the detection field, in particular to a detection driving circuit, a detection driving device and a detection method of a liquid crystal display panel. Background technique [0002] figure 1 It is a structural schematic diagram of a detection driving circuit of an existing liquid crystal display panel. The drive circuit includes a first GOA circuit 11 (Gate On Array), a second GOA circuit 12, and a detection signal input circuit 13 arranged on both sides of the liquid crystal display panel. The detection signal input circuit 13 passes through the first GOA circuit 11 and the second GOA circuit. The circuit 12 inputs the detection scan signal to the scan line 14 of the liquid crystal display panel and inputs the detection data signal to the data line 15 of the liquid crystal display panel; wherein the first GOA circuit 11 is used to input the detection scan signal to the pixel units of odd rows of the liquid crystal display pan...
