Problems solved by technology

[0003] However, during the VT test of the display panel to be cut, the electrostatic protection device will cause the VT test signal to pass through the electrostatic protection device to achieve signal crosstalk due to process fluctuations, resulting in mura phenomenon of uneven brightness on the display panel. Affect the detection and judgment of VT test

Abstract

The invention provides a display panel to be cut, a manufacturing method of the display panel and a display device, wherein the display panel to be cut comprises a display area and a non-display areasurrounding the display area, the non-display area comprises a fan-out area and a binding area which are arranged on one side of the display area in the first direction, and the binding area comprisessignal pin terminals which are connected with fan-out wires in the fan-out area in a one-to-one correspondence mode; a variable resistance part is arranged in a first to-be-cut area of the display panel to be cut, and the variable resistance part is electrically connected with the signal pin terminals so that electrostatic discharge channels are formed among the signal pin terminals in a first state, and an electrostatic protection effect is achieved; in the second state, test signals between the signal pin terminals are blocked, the crosstalk of visual test signals between the signal pin terminals is avoided, and therefore, the mura phenomenon of uneven brightness generated in the visual test of the display panel is improved, and the detection and judgment of the visual test are more accurate.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel to be cut, a manufacturing method of the display panel and a display device. Background technique [0002] In the production process of display panels, usually a large substrate is cut for the first time to form multiple small display panels to be cut. The first cutting method generally adopts cutting processes such as laser cutting or knife edge. During the process of production or in the production process such as transportation, external static electricity is usually brought into the display panel, which will affect the subsequent preparation of the display panel; Before the display panel formed by the second cutting can be bound to the driver chip IC, it is necessary to perform a visual test (VisualTest, VT test) on the display panel to be cut to detect whether the display panel bound to the driver chip is defective, so as to prevent the defective display pan...
