Problems solved by technology

[0004] The current frame glue coating method is generally to apply the frame glue multiple times in the cutting grooves between the display panels formed after cutting, each cutting groove needs to be coated once, the coating efficiency is not high, and it needs to be started and stopped Acceleration and deceleration lead to uneven coating, and arc bends are likely to occur at the corners of the display panel, especially when the coating is finished in the area of ​​the plastic frame, it is easy to produce bonding points, resulting in lower quality of the plastic frame

Embodiment Construction

[0016] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] Please refer to figure 1 with figure 2 , figure 1 It is a schematic flow chart of the sealant coating method of the first embodiment of the present invention, figure 2 It is a schematic diagram of the first path and the second path in the sealant coating method of the first embodiment of the present invention.

[0018] In this embodiment, the sealant coating method is used to form a sealant frame in the sealant frame area 12 at the edge of at least one display panel 11, and the sealant coating method may include the following steps:

[0019] Step S11: start coating from the first point outside the glue frame area to the second point inside the glue frame area along the first path.

[0020] In step S11, if figure 2 As sho...

Abstract

The invention discloses a frame glue coating method. The frame glue coating method includes the steps that coating is carried out from a first point outside a glue frame area to a second point in the glue frame area along a first path; coating is carried out from the second point in the glue frame area to a third point in the glue frame area so that a glue frame can be formed in the glue frame area in a coating mode at least; coating is carried out from the third point in the glue frame area to a fourth point outside the frame glue area along a second path. By means of the frame glue coating method in the mode, glue frame coating is more even, and the strength of the glue frame is higher.

Description

technical field [0001] The invention relates to the technical field of display panel manufacturing, in particular to a frame glue coating method. Background technique [0002] TFT liquid crystal displays are widely used in modern digital information equipment due to their small size, light weight, low energy consumption, and no radiation. [0003] A thin film transistor liquid crystal display generally includes a backlight module and a display panel. The display panel includes first and second substrates and a liquid crystal layer sandwiched between the first and second substrates. One of the first substrate and the second substrate is a thin film transistor array substrate, and the other is a color filter substrate. Usually, the panel is formed by using the overall pairing to form a relatively large display panel, and then cut the panel into multiple relatively small panels, and then in the plastic frame area at the edge of the relatively small panel Apply frame glue.
