Embodiment Construction

[0030] An embodiment of the present invention provides a display panel, which includes a first thin film layer and a second thin film layer; the first thin film layer and / or the second thin film layer are covered with insulating glue; and the first thin film layer is There is at least one concave structure at the hole, and the second film layer has at least one convex structure at the via hole; and at least one concave structure of the first film layer is in surface contact with at least one convex structure of the second film layer , and the contact surface contains a non-horizontal surface; because of the design of a convex structure and a concave structure at the via hole, and there is surface contact in the two structures, and the contact surface contains a non-horizontal surface, when the insulating glue shrinks, although it will Drive the film layer covered by the insulating glue, but the two layers of film layers have a convex structure and a concave structure in contact...

Abstract

The invention discloses a display panel. The display panel comprises a first thin film layer and a second thin film layer. The first thin film layer and / or the second thin film layer and / is covered with insulation glue. At least one concave structure is arranged at a via hole part of the first thin film layer, and at least one convex structure is arranged at a via hole part of the second thin film layer. The concave structures of the first thin film layer and the convex structures of the second thin film layer are in surface contact, and the contact surfaces include non-horizontal surfaces. The convex structures and the concave structures are arranged at the via hole parts and are in surface contact, and the contact surfaces include non-horizontal surfaces, so that when the insulation glue shrinks, although the part, covered by the insulation glue, of the thin film layers is driven to move, the two thin film layers are in contact all the time when the insulation glue shrinks due to the fact that the convex structures and the concave structures in contact are arranged at the via hole parts of the two thin film layers, and thus the undesirable phenomenon of grids is avoided.

Description

technical field [0001] The invention relates to the field of flat panel display, in particular to a display panel. Background technique [0002] Now, compared with the method of disposing the touch panel on the liquid crystal panel, the integration of the touch panel function and the liquid crystal panel can effectively reduce the thickness of the whole panel. Among them, the "In-cell" method is commonly used to integrate the touch panel and the liquid crystal panel, which is to embed a touch sensor in a pixel on a TFT array substrate. In the in-cell method, the TFT (Thin Film Transistor, thin film transistor)-PAD area, such as the integrated circuit board and the flexible circuit board area, is coated with insulating glue such as UV (Ultraviolet Rays, ultraviolet) glue to protect the panel. film structure. [0003] There are some via areas in the TFT-PAD area, for example, there are via areas between ITO (Indium tin oxide, indium tin oxide) and TPM (Touch Panel Metal, tou...
