Abstract

The invention provides a detection circuit of a display panel and a use method thereof. The detection circuit is characterized in that a first scanning detection line is connected with a main scanning line of a (2k+1)st line of pixel units, a second scanning detection line is connected with a main scanning line of a (2k)th line of pixel units, and the connecting state of a secondary scanning line of a (k+2m)th line of pixel units and a main scanning line of a (k)th line of pixel units is controlled according to a public signal of a public electrode line of the (k+2m)th line of pixel units; when a subpixel part is converted into a first time period under a first display state, the secondary scanning line of the (k+2m)th line of pixel units is connected with the main scanning line of the (k)th line of pixel units; when the subpixel part is converted into a second time period under the first display state, the secondary scanning line of the (k+2m)th line of pixel units is disconnected from the main scanning line of the (k)th line of pixel units. The detection circuit has the advantages that the technical problem of abnormality of unable detection of the display panel in the prior art is solved, and the display effect is improved.

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...
