[0027] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0029] See also Figures 1 to 3 , a method for manufacturing a display hole screen polarizer and OCA, comprising:

[0030] Step 1: According to the display drilling screen 10 provided by the customer, obtain relevant information of the display drilling screen 10;

[0031] Step 2: Design a corresponding punching die 20 according to the acquired information about the display drilling screen 10;

[0032] Step 3: Place the punching die 20 on the punching equipment, position and fix the punching die 20, and then place the polarizer and OCA to be punched on the punching die 20 for positioning and fixing;

[0033] Step 4: Debug the punching equipment, preset the path and pressure index, and start the punching equipment to punch the polarizer and OCA respectively.

[0034] It should be noted that, compared with the method of cutting the polarizer and OCA by laser, the present invention adopts the punching method, which can form the appearance of the polarizer and OCA in one step, thereby improving the production efficiency and reducing the production time and cost. The edges of the polarizer and OCA made by the punching method are neat, thereby improving the product quality of the polarizer and OCA, so as to better meet the assembly requirements of the display drilling screen 10. The punching method is a physical cutting method, which will not produce harmful gases and avoid the production process causing harm to the operator's body. Punching operations are performed on the polarizer and OCA separately, which can ensure that the polarizer and OCA remain in the best state during the cutting process, thereby improving the quality of the product.

[0035] See also Figure 2 In one embodiment, the relevant information of the display drilling screen 10 includes the size of the display drilling screen 10, the shape of the display drilling screen 10 and the drilling position in the display drilling screen 10. Only after obtaining the above relevant information of the display drilling screen 10, the punching die 20 produced subsequently can better meet the production requirements and improve the production accuracy.

[0036] See also Figure 3 In one embodiment, the punching die 20 includes a blade 21 and a base 22. The blade 21 has a height of 0.3 mm. The blade 21 includes an outer contour blade 211 and a drilling blade 212. The base 22 is provided with small holes corresponding to the holes of the display drilling screen 10. By setting the outer contour blade 211 and the drilling blade 212, the polarizer and the OCA are punched to form an outer contour and holes matching the display drilling screen 10. The small holes corresponding to the holes of the display drilling screen 10 are provided on the base 22 to facilitate the recovery of waste formed by drilling and cutting.

[0037] In one embodiment, the pressure index set by the punching device for the polarizer is greater than the pressure index set for the OCA. Since the hardness of the polarizer and the OCA are different, the pressure indexes for cutting the polarizer and the OCA are different. Therefore, the corresponding pressure index needs to be adjusted before cutting the polarizer and the OCA.

[0038] In one embodiment, a blade 21 is used to punch holes in the polarizer and the OCA respectively, and the waste materials formed will be discharged from the small holes. The operator will then recycle the waste materials discharged from the small holes. The waste materials formed by punching can be recycled, avoiding waste of resources and saving production costs.

[0039] In one embodiment, after the punching equipment punches the polarizer and the OCA respectively, the step of: cleaning the polarizer. During the punching process of the polarizer and the OCA, a certain amount of impurities and residues will be generated. In order to avoid affecting the display effect of the display perforated screen 10, the polarizer needs to be cleaned to remove impurities and residues on the surface of the polarizer.

[0040] In one embodiment, after the polarizer is cleaned, the step of drying the polarizer is further included. In this way, the water remaining in the polarizer due to cleaning can be removed to improve the performance of subsequent bonding with the OCA.

[0041] In one embodiment, after the polarizer is dried, the method further includes the step of bonding the polarizer to the OCA. During the bonding process, the outer contours and drill holes of the polarizer and the OCA need to be aligned, so as to ensure the bonding accuracy between the polarizer and the OCA.

[0042] In one embodiment, after laminating the polarizer and the OCA, the method further includes curing the polarizer and the OCA. The purpose of such arrangement is to form a stable bond between the polarizer and the OCA.

[0043] In one embodiment, after the polarizer and the OCA are cured, the step of: testing the product quality, and then assembling the product with the display drilling screen 10. In order to deliver better quality products to customers, it is necessary to test the quality of the product to detect whether the outer contour position and the drilling position of the polarizer and the OCA are aligned. After the outer contour position and the drilling position of the polarizer and the OCA are ensured to be aligned, the product is assembled with the display drilling screen 10.

[0044] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
