Embodiment 2

[0046] Embodiment 2 of the present invention provides a substrate mother board, refer to Figure 10 , the substrate motherboard includes: several first substrates, the coating equipment adopts a one-stroke continuous coating method to coat the frame glue on the multiple first substrates, and the coating equipment moves from a corner of the first substrate to the adjacent first substrate The coating line at one corner of is a broken line.

[0047] When the coating equipment moves from a corner of the first substrate to a corner of the adjacent first substrate, the coating line of the coating equipment is a broken line, and therefore, the shape of the sealant in the corresponding area is a broken line. And at this time, the position of the intersection point of the sealant on the main board of the substrate is at the corner of the first substrate, thereby effectively reducing the mura problem caused by the uneven thickness of the box.

[0048] In this embodiment, optionally, th...

Abstract

The invention discloses a frame glue coating method and a substrate mother board, which belong to the field of display technology. The coating method comprises: coating equipment adopts a one-stroke continuous coating method to apply frame glue to a plurality of first substrates; When the equipment moves from one corner of the first substrate to one corner of the adjacent first substrate, the coating line is a broken line. The technical solution of the present invention can set the position of the intersection point of the sealant at the corner of the first substrate, so that Effectively reduces the mura problem caused by the non-uniform thickness of the box. At the same time, the coating method provided by the invention is also suitable for coating the first substrate with special typesetting on the substrate motherboard, so it can effectively reduce the coating on the substrate motherboard. The time it takes for the cloth to seal the frame.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a coating method of a frame glue and a base plate. Background technique [0002] A liquid crystal display is a commonly used flat panel display at present, and a thin film transistor liquid crystal display (Thin Film Transistor Liquid Crystal Display, TFT-LCD for short) is a mainstream product in the liquid crystal display. [0003] TFT-LCD generally includes a first substrate, a second substrate, and a frame glue that bonds the first substrate and the second substrate to seal the liquid crystal between the first substrate and the second substrate. The coating of the frame glue is currently mostly done by dripping (OneDropFilling, referred to as ODF) process for production. Specifically, a substrate mother board is provided, and several first substrates are formed on the substrate mother board, and then coating equipment is used to coat each side of the first substrate. The co...
