Auxiliary frame sealing glue structure, box-aligning substrate and display device

Abstract

The invention provides an auxiliary frame sealing glue structure, a box-aligning substrate and a display device. The auxiliary frame sealing glue structure is arranged between an upper substrate and a lower substrate and comprises an opening structure, a first frame and a second frame connected with one end of the first frame, wherein the connecting position of the first frame and the second frame is in a sealed state. According to the auxiliary frame sealing glue structure, the junction position of the two frames on a windward surface in the rotation process is set to be in the sealed state, the opening structure is arranged in another position, the substrate is prevented from being affected by air resistance caused by rotation, the problem of deviation of a glass substrate in the rotation process is resolved, and further aligning deviation problem is effectively resolved. In addition, the uneven thickness of a box at the peripheral edge of a signal liquid crystal panel caused by uneven external atmospheric pressure acting on the inside and the outside of the substrate is avoided, and therefore the quality and yield of products are largely improved.

Description

technical field [0001] The invention relates to the field of display, in particular to an auxiliary frame sealing glue structure, a box matching substrate and a display device. Background technique [0002] Alignment shift is a very important quality problem of current LCD panel products. Alignment shift will lead to poor display panel contrast, color shift, etc., and the ET detection rate is low, resulting in serious material waste and quality problems at the back end. At present, the main reason for the misalignment of liquid crystal pre-dropping (ODF, one drop filling) process is that after the box is aligned and before the frame sealant is cured, due to the transfer equipment such as manipulators in the process of handling (only one side of the glass substrate can be fixed during handling), Make the two glass substrates offset relative to each other. [0003] Auxiliary sealant mainly refers to the sealant coated on the edge of the glass substrate. At present, the struct...

Problems solved by technology

[0003] Auxiliary sealant mainly refers to the sealant coated on the edge of the glass substrate. At present, the structure of auxiliary sealant is mainly divided into two types, closed state and non-closed state, because the structure of the closed state sealant has some disadvantages, such as When the TFT (Thin Film Transistor, thin film field effect transistor) substrate and the CF (color filter, color filter film) substrate are vacuum boxed, due to the uneven external atmospheric pressure on the inside and outside of the glass substrate, a single liquid crystal on the glass substrate The panel is subjected to different pressure on the cell, which will cause uneven cell thickness around a single LCD panel, affect the picture quality, and cause defects such as liquid crystal puncture; the non-closed state has the advantages of uniform cell thickness and no liquid crystal puncture, and is currently used more of

However, the non-sealed glass substrate will have the problem of alignment deviation during the transmission process before the sealant is cured

Because only one of the substrates is fixed when the manipulator is driving the glass, and both of them are rotating. In the non-closed state, during the rotation process, the position of the glass substrate (Glass) moving against the wind will generate considerable resistance, resulting in alignment. offset problem, see figure 1 , figure 1 The shown auxiliary frame sealing glue structure is in a non-closed state, including the opening structure 1e' located in the frame and the opening structure 1f' at the junction of any two frames. When the robot 2' moves the substrate from figure 1 Rotate to the position shown figure 2 In the process shown in the position, the frames 1a' and 1b' are on the windward side, and the opening structure 1f' located at the junction of the frames 1a' and 1b' will generate considerable resistance, so that the upper and lower substrates and the opening structure 1f' Offset occurs at the corresponding position 3', resulting in misalignment
