Abstract

The invention provides a display screen and a crack detection method thereof. A detection signal wire is arranged between a GIP signal wire and the edge of a base plate; one end of the detection signal wire is connected with the GIP signal wire, and the other end of the detection signal wire is connected with a terminal part; and signals are provided for the GIP signal wire and the detection signal wire through the terminal part. Therefore whether cracks destroying the detection signal wire exist or not is judged; the detection can be performed by only adding the signal wire and a probe connected with the detection signal wire on a cell test tool; and crack detection and a cell test work procedure are simultaneously performed, so that the detection time and the detection cost are reduced.

Description

technical field [0001] The invention relates to the field of flat panel displays, in particular to a display screen and a crack detection method thereof. Background technique [0002] With the thinning trend of consumer product screens, the substrate glass of OLED (Organic Light Emitting Display) or LCD (Liquid Crystal Display) also tends to be thinner, and the strength of the thinned glass will be weakened accordingly, and the edge of the glass is more likely to appear after cutting crack. Although there is an edging process that can remove small cracks on the edge to a certain extent, it still cannot remove deep cracks. The process after edging will also increase the cracks that have not been removed. At the same time, because of the thinning of the glass thickness, the process after edging will also easily add new cracks. [0003] If these cracks have destroyed the signal lines around the display (panel), the panel will display poorly. As a staff member, it is impossib...
