Display panel

By designing an open flat layer at the corner of the display panel's frame glue area, the frame glue is allowed to directly contact the dielectric layer, which solves the problem of insufficient adhesion of the flat layer, significantly improves the strength and reliability of the panel, and reduces line oxidation and Corrosive effects.

Problems solved by technology

However, in small-sized panels, the position opposite to the sealant is usually still provided with peripheral circuits, and removing the flat layer there may cause defects such as oxidation and corrosion of the circuits, which will affect the reliability of the panel

Abstract

The invention discloses a display panel which includes a display area and a frame glue area. The display panel includes a first base board, a dielectric layer, a flat layer, a second base board, a display medium, and the glue frame. The dielectric layer is arranged on the first base board. The flat layer is arranged on the dielectric layer and is provided with at least one exposed opening. The opening is correspondingly arranged in a corner of the frame glue area, and the width of the opening is reduced gradually as the distance from the corner of the frame glue area increases. The second base board is opposite to the first base board. The display medium is arranged in the display area between the first base board and the second base board. The frame glue is arranged in the frame glue area between the first base board and the second base board, and the frame glue is embedded into a part of openings. The display panel is excellent in strength.

Description

technical field [0001] The invention relates to a display panel, and in particular to a display panel with better strength. Background technique [0002] In a display panel, in order to increase the aperture ratio, a flat layer is usually used to reduce the coupling effect between metal lines of different layers. In this way, the spacing distance between the metal circuits of different layers can be reduced, so that the metal circuits of different layers can even have a positional relationship of overlapping up and down. Generally speaking, the flat layer covers the entire substrate, so the sealant used to bond the two substrates is actually disposed on the flat layer and in contact with the flat layer. However, the adhesion strength between the flat layer and the metal layer or the insulating layer is not good, so when the strength test is performed on the panel, the flat layer is often easily peeled off from the metal layer or the insulating layer, thereby affecting the s...
