Abstract

The present invention provides a detection circuit and its usage method for display panels.The main scanning line, according to the public signal control of the public electrode line of the K+2M row pixel unit of the K+2M row pixels of the K+2M pixel, the connection status of the main scanning line of the king pixel unit;During the first period of the pixels to the first display state, the secondary scanning line of the K+2M pixel unit is connected to the main scanning line of the K pixel unit of the K row pixel.During the second period of the state, the secondary scanning line of the K+2M pixel unit was disconnected from the main scanning line of the pixel unit of the K.The present invention solves the technical problems that the existing technology cannot detect the abnormal display panel, and improves the display effect.

Description

technical field [0001] The invention relates to the field of displays, in particular to a detection circuit and a use method of a 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. [0003] Existing detection circuit 1 such as figure 1 As shown, it includes a first scanning detection line 11 and a second scanning detection line 12, a common detection line 13, and pixel units 101-105, and each row of pixel units is correspondingly provided with a common electrode line 14, a main scanning line 15 and a sub-scanning line 16, where the main scanning lines of pixel units 101, 103, 105 in odd rows are connected to the first scanning detection line 11, an...
