Abstract

The invention discloses a display panel, a test method and a display device, relates to the technical field of display, and can solve the problems that a test pin of an existing display panel is arranged, a test probe is easy to wear in the test process, the consumption number of the test probe is large, and the test cost is high. The display panel comprises at least two to-be-tested circuits; a test pin is electrically connected with the at least two circuits to be tested; and a switching assembly is used for controlling connection and disconnection between the test pin and the circuit to be tested.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a testing method and a display device. Background technique [0002] With the continuous development of display technology, the application of display panels is becoming more and more extensive. Display panels are prone to many defects during the manufacturing process. These defects can usually be tested by setting a test process in the manufacturing process to test the relevant parameters of the devices in the display panel during the manufacturing process, so that defects can be found in advance and production costs can be reduced. In the testing procedure, the relevant parameters of the device connected to the test pins are usually tested by piercing the test pins with the test probes. [0003] However, with the existing arrangement of test pins, the test probes are easily worn during the test process, resulting in a high frequency of replacement o...
