Display panel, display device and test system thereof

Abstract

The invention discloses a display panel, a display device and a test system thereof, and belongs to the technical field of display. The display panel comprises a first bonding pad set and a second bonding pad set which are located in a non-display area, the first bonding pad set is used for being connected with a driving chip in a binding mode, and the second bonding pad set is used for being connected with a flexible circuit board in a binding mode; the control signal lines are located in the non-display area, the test signal lines are in one-to-one correspondence with the control signal lines, the control signal lines are used for being electrically connected with the driving chip through the first bonding pad set, and the test signal lines are used for being connected with the flexible circuit board through the second bonding pad set; the control circuit is located in the non-display area, the control circuit is electrically connected with the multiple control signal lines and the multiple test signal lines, and the control circuit is configured to control the control signal lines to be connected with the corresponding test signal lines in a time-sharing mode in the test stage. The plurality of test signal lines are connected with the same test point, so that the volume of the test point can be increased.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display panel, a display device and a testing system thereof. Background technique [0002] At present, display devices have become indispensable electronic products in people's lives. Display devices such as smart bracelets, mobile phones, and tablet computers have greatly increased the convenience of people's lives. [0003] The display device may include: a display panel and a flexible circuit board electrically connected to the display panel, and the flexible circuit board is provided with test points for analysis and testing. For example, during the testing phase of the display device, an external test device can be connected to this test point to obtain the display data of the display panel during the display process. After analyzing the display data, the display device can be completed. 's test. [0004] However, at present, the display device needs to...

Problems solved by technology

[0004] However, more and more functions need to be integrated in the current display device, resulting in more and more traces on the flexible circuit board in the display device, which will lead to less space for distributing test points in the flexible circuit board, which will Affects the volume of test points within the flexible circuit board

In this way, it is difficult for the external test equipment to make an effective electrical connection with this test point, resulting in a poor test effect and low efficiency for the display device.
