Problems solved by technology

However, in the current frame glue coating process, the sealant at the corner C around the panel is completed in the same panel, so that the corner arc around the corner is small, making it difficult to seal uniformly at the corner C, and common defects are more likely to occur

Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] refer to figure 2 , in the frame glue coating process of the embodiment of the present invention, a number of spaced display areas 10 are formed in an array on each motherboard 1, and each display area 10 is coated with a circle surrounding the corresponding display area 10. The frame glue 2, the four corners 2s of each frame glue 2 are rounded corners, and at least in the same row or column, two adjacent four corners 2s of every two adjacent frame glue 2 overlapping.

[0020] Compared with the prior art, since the ring-shaped frame glue 2 outside the single display area 10 has a large...

Abstract

The invention discloses a frame glue coating method. Each mother board is provided with a plurality of display areas at intervals in an arrayed mode. The outer side of each display area is coated with a circle of rectangular frame glue surrounding the corresponding display areas. The four corners of each piece of frame glue are circular beads. The adjacent four corners of the two adjacent pieces of frame glue are overlapped in pairs at least in the same row or column. The invention further discloses a frame glue structure and a liquid crystal box. Frame glue coating lines subjected to primary coating cross over the display areas of two adjacent panels, and a frame glue area on one panel is formed in the mode that the frame glue coating line on the panel intersects with the frame glue coating line of the adjacent panel, so that single coating of a single nozzle is large in size, the diameter of the circular beads at the corners can be larger, coating difficulty is reduced, the width of the corners of the frame glue can be consistent with that of other parts, and the occurrence rate of common defects is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a sealant coating method, a sealant structure and a liquid crystal box. Background technique [0002] The ODF (One Drop Filling, drop-type injection method)) box-making process mainly adopts the method of nozzle coating for glue application. This glue application method is to drop the liquid crystal according to the calculated amount on the substrate that already has a frame glue pattern. , and then bond it with another substrate in vacuum, and then cut after thermal curing to form multiple panel monomers. This method not only improves the utilization rate of the liquid crystal, but also reduces the processes such as sealing, not only reduces the cost, but also shortens the production cycle. [0003] Because the frame glue material used in ODF is sensitive to heat, and the temperature of the screen printing frame glue process is not easy to control, so the nozzle coating method...
