Description

Technical Field

[0001] The present invention relates to the field of display technology, and particularly to a low-cost mask plate structure and manufacturing method. Background Art

[0002] With the development of science and technology, intelligent handheld electronic devices such as mobile phones and tablet computers are everywhere in life. Most of these devices use touch display screens for collection and identification for interaction. As an important tool for the yellow light process of touch display, for different models designed by different customers, more than 95% of them require dedicated mask plates to meet customer needs.

[0003] Due to the process characteristics of the yellow light process, the price of the mask plate is relatively high, and usually 3 - 5 mask plates are needed for one model, which poses a relatively large pressure on the confirmation of tooling drawings, the production of samples, and the storage of tooling; at the same time, the delivery of such mask plates is also relatively long. In view of this situation, it is very necessary to design a low-cost mask plate to reduce the sample proofing cost, speed up the sample delivery time, improve the sample processing efficiency, and enhance the overall competitiveness at the customer side. Therefore, a low-cost mask plate structure and manufacturing method are proposed to solve the above problems. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a low-cost mask plate structure and manufacturing method, which have the advantages of improving processing efficiency and reducing processing costs, and solve the problem of poor processing efficiency.

[0005] To achieve the above object, the present invention provides the following technical solution: A low-cost mask plate structure includes a base layer. On one side of the base layer, an anti-reflection and anti-glare layer is fixedly connected, and on the other side of the base layer, an anti-glare layer is fixedly connected. On the sides of the anti-reflection and anti-glare layer and the anti-glare layer away from the base layer, an anti-fingerprint layer is fixedly connected. On the side of the right anti-fingerprint layer away from the base layer, a PET film layer is fixedly connected.

[0006] Further, the base layer is a glass substrate layer, and the anti-reflection and anti-glare layer is an AR light-transmitting layer.

[0007] Further, the anti-fingerprint layer is composed of a mixture of SiO2 and AF materials, and the anti-glare layer is a SiO2 colloidal solution layer.

[0008] Further, the PET film layer is a PET film material with a pattern already made.

[0009] A manufacturing method for a low-cost mask plate structure includes the following steps:

[0010] S1. Take a glass substrate with a thickness of 3.2 - 3.5 mm and an outer dimension of 620 * 720 mm;

[0011] S2. After chamfering, rounding the corners and double-sided polishing the glass substrate, and ensuring the relative parallelism of the upper and lower surfaces of the glass substrate, then check that there are no scratches, vacuum, air bubbles, etc. in the 550*650 mm area at the center of the glass substrate.

[0012] S3. First, coat the entire surface of side A of the glass substrate with an anti-reflection and anti-glare layer as the anti-reflection and anti-glare layer of the AR light-transmitting layer for anti-reflection effect. Then, coat an anti-fingerprint layer on the anti-reflection and anti-glare layer for easy cleaning.

[0013] S4. Sequentially coat an anti-glare layer and an anti-fingerprint layer on side B of the glass substrate for easy cleaning.

[0014] S5. Attach the PET film layer with the required pattern made on it to the anti-fingerprint layer on side B of the glass substrate to obtain a mask plate structure.

[0015] Further, in step S1, when the equipment operates, a large glass substrate with a specification of 550*650 mm is taken as an example. In the process of inspecting the glass substrate in step S2, slight defects are acceptable in other areas of the glass substrate.

[0016] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0017] For this low-cost mask plate structure and manufacturing method, since the base layer is a glass substrate and anti-fingerprint layers made of AF material are coated on both its A / B sides, it is convenient to clean. And on side A, an anti-reflection and anti-glare layer made of AR material is also coated to increase the light transmittance, reduce the light energy loss during the exposure process, improve the utilization rate of the light source, extend the light source life. And on side B of the base layer, an anti-glare layer is coated, which can effectively improve the viewing angle, reduce the interference of ambient light, and reduce screen reflection. Moreover, patterns can be made on the PET film layer, and it has a large price advantage. The PET with the pattern made can be directly attached to the glass substrate with an anti-glare layer, and the operation is simple, thus reducing the production cost.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figure 1-2 , a low-cost mask plate structure in this embodiment, includes a base layer 1. The base layer 1 is a glass substrate layer, enabling the substrate to have the special effects of low reflectivity and low thermal expansion.

[0023] One side of the base layer 1 is fixedly connected with an anti-reflection and anti-glare layer 2. The anti-reflection and anti-glare layer 2 is an AR light-transmitting layer. By increasing the glass light transmittance and reducing the glass reflectivity to achieve the purpose of anti-glare, it is generally coated with high and low refractive index materials stacked crosswise, and can be deposited by vacuum evaporation or magnetron sputtering.

[0024] The other side of the base layer 1 is fixedly connected with an anti-glare layer 4. The anti-glare layer 4 is a SiO2 colloidal solution layer, which is obtained by performing single-sided or double-sided special treatment on the glass surface to achieve the effect of multi-angle diffuse reflection, thereby increasing the viewing angle of the picture, reducing the interference of ambient light, reducing screen reflection, and can be formed into a film by the method of spraying + baking.

[0025] Both sides of the anti-reflection and anti-glare layer 2 and the anti-glare layer 4 away from the base layer 1 are fixedly connected with an anti-fingerprint layer 3. The anti-fingerprint layer 3 is composed of a mixture of SiO2 and AF materials. According to the lotus leaf principle, a layer of nano-chemical material is coated on the outer surface of the glass, reducing the surface tension of the glass to the lowest level, reducing the contact area between dust and the glass surface by 90%, making it have strong hydrophobic, anti-oil and anti-fingerprint capabilities; keeping the video glass panel bright and clean for a long time.

[0026] One side of the right anti-fingerprint layer 3 away from the base layer 1 is fixedly connected with a PET film layer 5. The PET film layer 5 is a PET film material with a pattern already made, increasing the convenience of attaching the PET film layer 5.

[0027] In this embodiment, since the base layer 1 is a glass substrate and the anti-fingerprint layer 3 made of AF material is plated on both its A and B surfaces, it is convenient to clean. And the AR material anti-reflection and anti-glare layer 3 is plated on the A surface at the same time to increase the light transmittance, reduce the light energy loss during the exposure process, improve the utilization rate of the light source, and extend the light source life. The anti-glare layer 4 is also plated on the B surface of the base layer 1, which can effectively increase the viewing angle, reduce the interference of ambient light, and reduce screen reflection. Moreover, patterns can be made on the PET film layer 5, and it has a great price advantage. The PET with a pattern can be directly attached to the glass substrate with the anti-glare layer 4, and the operation is simple, thus reducing the production cost.

Then check that there are no scratches, vacuum, bubbles, etc. in the 550*650mm area at the center of the glass substrate. During the inspection of the glass substrate, slight defects in other areas of the glass substrate are acceptable;

[0032] S3. First, coat the entire surface of the A side of the glass substrate with an anti-reflection and light-transmitting layer 2 of the AR light-transmitting layer to play a role in increasing light transmission; then coat an anti-fingerprint layer 3, that is, AF coating, on the anti-reflection and light-transmitting layer 2, which is convenient for cleaning. After coating, the water contact angle is greater than 115°, and the film thickness uniformity is within 3%;

[0033] S4. Coat an anti-glare layer 4 and an anti-fingerprint layer 3, that is, AF coating, on the B side of the glass substrate, that is, the base layer 1 in turn, which is convenient for cleaning. After coating, the water contact angle is greater than 115°, and the film thickness uniformity is within 3%;

[0034] S5. Attach the PET film layer 5 with the required pattern made to the anti-fingerprint layer 3 on the B side of the glass substrate. The film material attachment requirements are flat without wrinkles and close to the glass substrate to obtain the mask plate structure.
