Embodiment Construction

[0044] In order to enable those skilled in the art to better understand the technical solution of the present invention, a display panel of the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0045] In public technology, such as figure 2 As shown, the flexible AMOLED display panel is laser cut from the mother board, and the organic film layer at the cutting line S position in the display panel (such as polyimide substrate PI / flat layer PLN / pixel definition layer PDL, etc.) When carbonized, this will cause the organic film layer of the AMOLED display panel along the cutting line S to form a circle of carbonized area P. The width of the carbonized area P is related to the laser process. Usually, the width of the carbonized area P is 100-200 μm; The carbonized organic film layer has a certain conductivity, and the static electricity accumulated by the friction of the copper rod on the surface of the glass cov...

Abstract

The invention provides a display panel, and the display panel comprises a display substrate and a cover plate, wherein the cover plate covers the display side of the display substrate; a carbonization layer is formed in the edge area of the display substrate; the display panel further comprises a static electricity dredging structure which is arranged on the edge area of the display substrate, and the static electricity dredging structure is connected with the carbonization layer and used for dredging static electricity accumulated on the cover plate. According to the display panel, by arranging the electrostatic dredging structure, static electricity on the carbonization layer can be dredged, and the static electricity is prevented from forming an electric field in the carbonization layer; meanwhile, the static electricity is prevented from entering the display area of the display substrate and forming the electric field, and the static electricity accumulated on the cover plate can be prevented from inducing charges with opposite polarities on the heat dissipation film layer on the side of the display substrate; therefore, an electric field is prevented from being formed between the cover plate and the heat dissipation film layer, characteristic offset of a thin film transistor in a pixel circuit in a display area of the display substrate caused by static electricity is avoided, leakage current of the thin film transistor is prevented from being increased, and the phenomenon that the display panel emits light is avoided.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display panel. Background technique [0002] At present, with the development of OLED (Organic Light-Emitting Diode, organic light-emitting diode) display technology, consumers have put forward more stringent requirements for AMOLED display products, and more and more customers have begun to pay attention to the display effect of the screen under the copper rod test . [0003] At present, the AMOLED (Active-matrix organic light-emitting diode, active-matrix organic light-emitting diode or active-matrix organic light-emitting diode) display panel has the problem of copper rods shining. The reasons are: if figure 1 As shown, the glass cover plate 2 of the display panel will accumulate a large amount of static electricity after being rubbed by copper rods for many times, and the static electricity will enter the electret material such as the base film layer 14 in the...
