Process method for producing large-size LCD (Liquid Crystal Display) by adopting pouring mode

Abstract

The invention discloses a process method for producing a large-size LCD (Liquid Crystal Display) by adopting a pouring mode. The process method comprises the following steps of: designing an optimal sealing position, wherein the outermost sealing position is 2 / 3 of a pouring radius from the side edge; carrying out pre-pouring, specifically, putting 2 or 3 empty liquid crystal boxes and 2-3 g of liquid crystals into a pouring machine, and putting the liquid crystals and the empty box which is being poured into a drying oven at the temperature of 55-65 DEG C to expand the liquid crystals after the liquid crystals are expanded by 5-10 mm in the empty boxes; and recording a cavity position S after the liquid crystals are fully expanded; and carrying out formal batch pouring, specifically, putting 30-40 empty boxes in batch and 7-10 g of liquid crystals into the pouring machine, waiting until the liquid crystals are expanded for 5-10mm in the empty boxes, moving the empty boxes for expanding the liquid crystals and the liquid crystals into the drying oven at the room temperature of 23 DEG C to expand the liquid crystals, waiting until the liquid crystals are expanded to exceed 10-15 mmof the cavity position S of appearing in the pre-pouring process, and moving the liquid crystals and the empty boxes for expanding the liquid crystals into the drying oven at the temperature of 55-65DEG C until the liquid crystals are fully expanded. The process method can avoid sealing side cavities, the formal pouring process can be accurate and rapid by utilizing the cavity position obtained by pre-pouring, the pouring time is shortened, and the pouring efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of display manufacturing technology, in particular to a method for producing a large-size LCD by pouring. Background technique [0002] In recent years, bus stop signs have become electronic, and large-size LCDs have been applied in such fields. Because black and white large-size LCDs are cheaper than TFTLCDs, and the size can be customized, so in such applications, black and white large-size LCDs It has also been applied to a certain extent. However, since the size of black and white LCDs is generally relatively small, and the size of 5 inches is already the largest size of products produced before, so the manufacturing process of black and white LCDs is all infusion, but the size of such bus stop signs must be larger. Large, with 14 or 16 inches or more, the original perfusion method is no longer suitable for the production of such large-size LCDs. Contents of the invention [0003] In order to solve t...
