Embodiment 1
[0031] This embodiment provides a thinning method for a display panel, the display panel includes a first substrate and a second substrate for a box, and the thinning method includes the following steps:
[0032] S1 coating a transition layer on the surface of the first substrate away from the second substrate;
[0033] S2 attaching protective glue on the transition layer;
[0034] S3 performs single-side chemical thinning on the second substrate.
[0035] In the thinning method of the display panel in this embodiment, a transition layer is first coated on the surface of the first substrate away from the second substrate, and then a protective glue is attached on the transition layer, and then the second substrate is subjected to one-sided chemical thinning. Thin, to protect the first substrate from chemical thinning during this period, so as to achieve the purpose of asymmetric thinning. The first substrate of the display panel prepared by the method is thicker than the sec...
Embodiment 2
[0037] This embodiment provides a method for thinning a display panel, such as figure 2 As shown, the display panel includes a first substrate and a second substrate of the box, and the thinning method includes the following steps:
[0038] S1 Coat the transition layer 3 on the surface of the first substrate away from the second substrate.
[0039] Preferably, the first substrate is a color filter substrate 2 , and the second substrate is an array substrate 1 .
[0040] That is to say, the color filter substrate 2 is usually made thicker, so that the display panel has high strength and good support ability, and can quickly recover when subjected to external force such as pressing, so as to avoid defects such as abnormal display of the screen.
[0041] Preferably, the transition layer 3 is made of paraffin.
[0042] That is to say, the first substrate is protected with paraffin wax, which is beneficial to the subsequent application of the protective glue 4. More importantly,...
Embodiment 3
[0066] This embodiment provides a method for thinning a display panel with a thickness of 1.200 mm and a size of 1100×1300 mm, the display panel includes a color filter substrate and an array substrate in a box. The flow of the thinning method of the display panel in this embodiment is as follows: image 3 As shown, the specific steps are as follows:
[0067] Heat the paraffin to liquid state (50-80°C), then apply it on the back of the color filter substrate, and cool to room temperature;
[0068] Paste a layer of protective glue 4 on the above-mentioned paraffin;
[0069] Add the etching solution into the container, and then add the above-mentioned display panel into the etching solution for soaking, and the soaking time is 15-40 minutes;
[0070] Heating the paraffin to 50-80°C, tearing off the protective glue 4, cooling to room temperature, cleaning the paraffin with a solvent, and then further cleaning with ozone;
[0071] The etching solution is added into the containe...
