Problems solved by technology

from figure 1 and figure 2 It can be seen from the coating path of the sealant shown in the figure that in the above two coating methods of the sealant, there is a common problem: there is a corner in the coating path of the nozzle, and the nozzle is coated at the corner When sealing the frame, it is easy to have the problem of uneven coating of the sealant
[0004] Therefore, how to avoid the problem of uneven coating of the sealant is a technical problem urgently needed by those skilled in the art.

Embodiment Construction

[0040] The specific implementation of the coating method of the frame sealant provided by the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] The shape and size of each display area on the substrate in the drawings do not reflect the actual scale, and the purpose is only to schematically illustrate the content of the present invention.

[0042] A method for coating a frame sealant provided in an embodiment of the present invention includes:

[0043] Use a plurality of nozzles to coat the sealant on each area to be coated on the substrate along the longitudinal coating line and the transverse coating line; wherein,

[0044] like image 3As shown, the substrate 101 has a plurality of rectangular display areas 102 arranged in a matrix, and the area to be coated (such as image 3 Shown by the dotted line) surrounds the display area 102; the parts on the same vertical line in each area to be coated form a...

Abstract

The invention discloses a coating method for frame sealing glue. According to the method, the frame sealing glue is coated on the areas to be coated on a substrate along longitudinal coating lines and the horizontal coating lines by means of a plurality of nozzles. Due to the way of coating the frame sealing glue in a cross way of longitudinally coating and horizontally coating by means of the nozzles, the nozzles cannot be cornered in the coating paths, and the problem that the frame sealing glue is unevenly coated due to the cornering is solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for coating a frame sealant. Background technique [0002] Coating a frame sealant on a substrate is an important step in the process of display panel assembly. The sealant can bond the two substrates together, and adding glass fiber or silicon balls to the sealant can maintain the thickness of the box between the two substrates. The uniform coating of the sealant can ensure the uniformity of the thickness of the box between the two substrates, thereby ensuring the display quality of the display panel. [0003] At present, there are two common methods of coating frame sealant. One method of coating frame sealant is as follows: figure 1 As shown, the nozzle spraying out the sealant is independently coated around each display area 102 on the substrate 101; another method of coating the sealant is: the nozzle first follows the figure 2 The coating is carried out in the...
