Problems solved by technology

Therefore, the sealing glue 13 does not completely isolate each sub-liquid crystal display panel 12 from the outside world, and the glue material is very easy to leak inward from the opening 130 to the sub-liquid crystal display panel 12 when the UV glue is applied in the thinning process. During immersion etching, due to the lack of UV glue at the opening 130, the corrosion solution will also infiltrate from here, causing the sub-LCD panel 12 at the opening 130 of the sealing glue 13 to be polluted by UV glue and corroded by the etching solution and scrapped.

Abstract

The invention discloses a liquid crystal displaying panel. The liquid crystal displaying panel comprises two substrates and frame sealing glue, wherein the two substrates are opposite to each other; the frame sealing glue is arranged between the two substrates, is positioned on the peripheries of the two substrates and comprises a plurality of frame sealing glue units; each frame sealing glue unit comprises a connecting section and end structures positioned at two ends of the connecting section; the end structures are hook-shaped; and the end structures of each two adjacent frame sealing glue units are coupled to each other so as to form a bent channel. By using the bent channel of the liquid crystal displaying panel, UV (ultraviolet) glue and corrosive liquid are stopped in a panel thinning process, a phenomenon that the UV glue and the corrosive liquid permeate in the liquid crystal displaying panel, and a secondary liquid crystal displaying panel is scrapped is avoided, the yield rate is improved, the lengths of the frame sealing glue units can be accurately controlled, poor coating of frame sealing glue is avoided, and owing to a coupling structure, the displaying panel cannot be affected even if wires are disconnected in a poor state.

Description

technical field [0001] The invention designs a flat panel display technology, and in particular relates to a liquid crystal display panel. Background technique [0002] Liquid crystal displays are widely used in various fields due to their small size, light weight, and low radiation. The working principle of the liquid crystal display is: by changing the voltage applied to the liquid crystal to change the deflection angle of the liquid crystal molecules, thereby controlling the rotation direction and polarization state of the polarized light, so as to realize the change of the display state of the liquid crystal display. [0003] In the production process of the liquid crystal display device, a plurality of sub-liquid crystal display panels are usually arranged on two large glass substrates, and each sub-liquid crystal display panel is aligned and bonded by a main sealing frame around the sub-liquid crystal display panel. The liquid crystal display panel is formed by the tw...
