Flexible substrate attaching process and its frame glue pattern

Abstract

The invention discloses a bonding process of flexible substrates and a frame rubber pattern thereof. The bonding process mainly for manufacturing flexible liquid crystal displays comprises steps: between a first substrate and a second substrate, firstly bonding the frame rubber pattern to a first substrate by utilizing patterns of frame rubber gaps, filling liquid crystal into the frame rubber, compressing the first and second substrates, then automatically exhausting air bubbles from the frame rubber gaps, and finally leading the compressed frame rubber to generate expansion deformation, thereby automatically sealing the frame rubber gaps. The bonding process utilizes the designed frame rubber gap patterns to exhaust air bubbles easily by the flexible liquid crystal display during bonding process in atmosphere, and enable the frame rubber gap patterns to be automatically sealed directly in the bonding process.

Description

technical field [0001] The present invention relates to a laminating process of flexible substrates and a frame glue pattern used therefor, in particular to a laminating process of flexible substrates suitable for atmospheric lamination and capable of eliminating air bubbles and automatic sealing and its The frame glue graphics used. Background technique [0002] Liquid crystal flat panel displays need liquid crystal filling and sealing during the manufacturing process. At present, there are two methods generally used in the industry, one is the vacuum capillary suction method, and the other is the vacuum drop liquid injection method (ODF, One Drop Filling). The way of vacuum capillary suction is to put the pasted panel into a cabin, after vacuuming, put the panel with a notch in the liquid crystal tank, and break the vacuum in the cabin, because there is a vacuum volume in the panel, so it can Inhale the liquid crystal into the panel to achieve the purpose of filling the ...

AI Technical Summary

Problems solved by technology

Both of the above two liquid crystal injection methods require vacuuming, so the process time is longer and the equipment cost is high, and the liquid crystal is wasted in the process of vacuum capillary suction, and process actions such as cleaning and sealing are required, the process time is longer and the cost is higher. High, these two liquid crystal filling methods are not suitable for filling and sealing of flexible liquid crystal displays

Relatively, flexible liquid crystal displays are more suitable for low-cost atmospheric operation, but the most troublesome air bubbles and additional sealing processing problems have not yet obtained a better solution when filling and sealing in the atmosphere
