Abstract

The embodiment of the present invention provides a display panel and a display device, and relates to the technical field of display. The invention can improve the accuracy of test signals acquired ina VT test. The display panel includes a substrate; a non-display area, wherein the substrate in the non-display area is provided with test leads, and the test leads include a circuit board lead and atest point lead, and a test pad and a test circuit board pin are disposed in the non-display area. The circuit board lead is electrically connected to the test circuit board pin, and the test point lead is electrically connected to the test pad, wherein the test pad is used for the alignment marking of the circuit board.

Description

Technical field [0001] The present invention relates to the field of display technology, and in particular to a display panel and a display device. Background technique [0002] During the manufacturing process of the display panel, defects may occur. If the display panel is discovered after the IC is bound, the IC cannot be used again. Therefore, a Visible Test (Visible Test, VT) test, i.e. imitating the IC to light up the display panel for testing. [0003] At present, it is necessary to perform VT test on the display panel through the test circuit board. The test circuit board pins are set on the display panel to be VT tested. First, the test circuit board and the test circuit board pins on the display panel are pressed together to achieve Test the electrical connection between the circuit board and the display panel, and then provide the input signal to the display panel through the test circuit board, and at the same time, obtain the output signal from the display panel throu...
