Abstract

The invention provides a display substrate, a detection method thereof and a display device, and belongs to the technical field of display. The display substrate comprises at least two circles of conductive coils surrounding a preset area of the display substrate, a first detection terminal and a second detection terminal; the switch control unit is used for controlling the first end of the conductive coil to be disconnected or connected with the first detection terminal and controlling the second end of the conductive coil to be disconnected or connected with the second detection terminal; and the detection unit is used for judging whether the conductive coil is broken or not according to the resistance between the first detection terminal and the second detection terminal. According to the technical scheme, whether the display substrate has cracks or not can be effectively detected.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, a detection method thereof, and a display device. Background technique [0002] OLED (Organic Light-Emitting Diode, organic light-emitting diode, referred to as OLED) display device has thin, light, wide viewing angle, active light emission, continuously adjustable light color, low cost, fast response speed, low energy consumption, low driving voltage, With the advantages of wide operating temperature range, simple production process, high luminous efficiency and flexible display, it has been listed as a promising next-generation display technology. [0003] However, due to the process and raw materials, the edge of the OLED display substrate is prone to cracks, which eventually leads to defective black spots on the edge of the display product or at the position of the hole. Contents of the invention [0004] The technical problem to be solved by the pres...
