Embodiment 1

[0046] The display panel used in this embodiment is as Figure 6 As shown, the display screen includes an upper substrate 10 and a lower substrate 20 arranged in parallel. The surface of the lower substrate 20 near the upper substrate 10 has a region to be coated protruding from the upper substrate 10, and the upper substrate 10 has a region to be coated that is close to the region to be coated. 210 of the first edge, and the above-mentioned display screen also includes a sealing member 30 arranged between the upper substrate 10 and the lower substrate 20, the upper substrate 10 has one end of the first edge, and an accommodation space is formed between the sealing member 30 and the lower substrate 20 , the sealing method provided in this embodiment includes the following steps:

[0047] Use TUFFY glue to carry out six coating processes on the region 210 to be coated along the direction parallel to the first edge, so that each coating process forms a plurality of glue-coated r...

Embodiment 2

[0049] The difference between this embodiment and embodiment 1 is:

[0050] Odd-numbered coating processes have opposite coating directions to even-numbered coating processes.

Embodiment 3

[0052] The difference between this embodiment and embodiment 1 is:

[0053] A group of adjacent glue-coated regions 40 near the first edge of the glue-coated regions 40 are adjacent, the width of the glue-coated regions 40 is 0.5 mm, and the interval between the start times of each coating process is 1 s.

Abstract

The invention provides a sealing method of a display screen frame. The sealing method of the display screen frame comprises the following step: coating a to-be-coated region in the direction of a first edge which is parallel to an upper substrate by using glue so that a plurality of gluing regions are formed on a lower substrate by various coating processes in a one-to-one correspondence manner, wherein the various gluing regions are successively formed along the direction which is away from the first edge. Therefore, the inner side of the first edge which is close to the to-be-coated region is coated with glue, then step-by-step outward coating is carried out, multiple gluing regions can be formed on the to-be-coated region, penetration time of the gluing region on the inner side is prolonged relatively, a seam can be filled with glue which is close to the gluing region of the first edge as much as possible, the amount of glue which permeates into the seam is increased, uniformity ofsolidified glue of the inside and the outside of the seam after the glue is solidified is improved effectively, and the sealing effect of the display screen frame is improved. In addition, the efficiency of the sealing process is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for sealing a frame of a display screen. Background technique [0002] In the switchable 3D display module manufacturing process, after sealing the liquid crystal material between the upper substrate 10' and the lower substrate 20' with the sealing member 30', a liquid crystal material is formed between the sealing member 30' and the ends of the two substrates. The terminal part 40', in order to improve the reliability of the product, it is usually necessary to protect the ITO circuit by sealing the above-mentioned terminal part 40', so as to protect the terminal part from being corroded after the display screen is bonded with the circuit board such as FPC. In the prior art, the display frame of the terminal part 40' without sealing treatment is as follows: figure 1 shown. [0003] In the prior art, after the production equipment seals the glue, it will immediately en...
