[0002] Screen is a kind of device or electrical appliance for displaying image and color. It is divided into screen and phosphor screen, also called display screen. It is widely used in mobile phone, computer, display, television and the device with image or text display function. After the full pasting of the current blind hole project product, hot melt point glue 1-2 is first pointed on the periphery of the hole 1-4 of the lower polarizing plate 1-1 to prevent the lower polarizing plate 1-1 from leaking light at the edge of the hole, which affects the use of the camera. After pointing the hot melt point glue, a protective film 1-3 is attached to the hole of the lower polarizing plate 1-1, as shown in the structure of Figure 11 and Figure 12 If the surface of the traditional protective film 1-3 is pressed, the glue may be transferred to the lower polarizing plate 1-1, resulting in the residual glue paste on the surface of the polarizing plate. The residual glue paste contaminates the use of the product. Therefore, a hole protection film for display module is proposed. SUMMARY

[0003] Therefore, it is necessary to provide a hole protection film for display module. The protective film is designed as a non-adhesive film body, and is used in combination with strong and weak glue double-sided adhesive. The side with strong adhesion is attached to the protective film, and the side with weak adhesion is attached to the polarizing plate. When the protective film is torn, the glue will not be left on the polarizing plate.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A hole protection film for display module, comprising:

[0006] A cover plate is installed with an LCD module on one side of the cover plate.

[0007] A blind hole is provided on the LCD module, and a hot melt point glue is provided on the periphery of the blind hole.

[0008] A double-sided adhesive has a strong adhesive side and a weak adhesive side. The double-sided adhesive is attached to the edge of the blind hole on the LCD module through the weak adhesive side.

[0009] A protective film is attached to the double-sided adhesive through the strong adhesive side.

[0010] Further, the double-sided adhesive has a hole and is arranged corresponding to the blind hole.

[0011] Further, the protective film has a break line at the position corresponding to the hole.

[0012] Further, the thrust line is a cross thrust line.

[0013] Further, the thrust line is a parallel thrust line.

[0014] Further, the protective film has a fitting end and a tearing end.

[0015] The fitting end is an arc surface and coincides with the edge of the double-sided adhesive.

[0016] Further, the two sides of the tearing end have arc chamfers.

[0017] Further, a triangular gap is cut between the two arc chamfers.

[0018] Further, a separation slit is cut near the triangular gap of the tearing end, and the separation slit and the tearing end are in communication with each other.

[0019] Further, the LCD module comprises an upper polarizing sheet, an upper glass sheet, a lower glass sheet and a lower polarizing sheet.

[0020] The upper polarizing sheet, the upper glass sheet, the lower glass sheet and the lower polarizing sheet are sequentially attached to form the LCD module, and the blind hole is formed in the lower polarizing sheet.

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] The protective film for the display module is designed as a non-adhesive film body, and is used in cooperation with strong and weak double-sided adhesive, so that the side with strong adhesion is attached to the protective film, and the side with weak adhesion is attached to the polarizing sheet. When the protective film is torn, the protective film and the double-sided adhesive are separated from the surface of the polarizing sheet due to the strong adhesion of the protective film and the double-sided adhesive, so the double-sided adhesive does not separate from the protective film, and the side with weak adhesion does not remain on the polarizing sheet.

[0023] Through the design of the arc chamfer, the edge of the protective film can be chamfered, so that the situation of being easily scratched due to the sharp edge is avoided. Since the design is arc-shaped, the force of the contact surface during contact with external objects can be dispersed when the contact force is dispersed. The situation that the protective film is easily warped and falls due to excessive force is reduced, and the firmness of the protective film is improved.

[0024] Through the design of the separation slit and the triangular gap, the tearing end can be separated, and the separated tearing end is divided into two parts. When the protective film is subsequently torn, one of the arc chamfers can be pressed, so that the two arc chamfers are staggered in angle. The protective film is easily torn through the staggering.

[0025] Through the design of the broken line, the external air can interact with the air in the blind hole, so that the air can enter the camera hole, meeting the needs of hot melting point glue curing. BRIEF DESCRIPTION OF DRAWINGS

[0045] As described in the background, the traditional protective film surface has glue, and if the protective film surface at the opening is pressed, the glue may be transferred to the lower glass surface, resulting in contamination and affecting the use of the product.

[0046] In order to solve this technical problem, the present application provides an opening protective film for a display module, which is applied to an LCD module.

[0047] Specifically, please refer to Figures 1-12 , the opening protective film for a display module specifically comprises:

[0048] Cover plate 1, an LCD module 2 is installed on one side of the cover plate 1;

[0049] Blind hole 21, which is opened on the LCD module 2, and a hot melt point glue 22 is arranged on the periphery of the blind hole 21;

[0050] Double-sided adhesive 3, which has a strong adhesive surface 31 and a weak adhesive surface 32, the double-sided adhesive 3 is pasted on the edge of the blind hole 21 on the LCD module 2 through the weak adhesive surface 32;

[0051] Protective film 4, which is pasted with the double-sided adhesive 3 through the strong adhesive surface 31.

[0052] The opening protection film for the display module is characterized in that the protection film 4 is designed as a non-adhesive film body, and is used in cooperation with a strong-weak glue double-sided adhesive, so that the side with strong adhesion is attached to the protection film 4, and the side with weak adhesion is attached to the polarizing sheet.

[0053] In order to make the person skilled in the art better understand the utility model scheme, the technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings.

[0054] It should be noted that the embodiments in the utility model and the features and technical solutions in the embodiments can be combined with each other without conflict.

[0055] It should be noted that: similar labels and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0056] Please refer to Figures 1-5 The opening protection film for the display module comprises a cover plate 1, an LCD module 2 is installed on one side of the cover plate 1, a blind hole 21 is arranged on the LCD module 2, a hot melting point glue 22 is arranged on the periphery of the blind hole 21, the LCD module 2 comprises an upper polarizing sheet 23, an upper glass sheet 24, a lower glass sheet 25 and a lower polarizing sheet 26, wherein the upper polarizing sheet 23, the upper glass sheet 24, the lower glass sheet 25 and the lower polarizing sheet 26 are sequentially attached to form the LCD module 2, and the blind hole 21 is arranged on the lower polarizing sheet 26.

[0057] The opening protection film for the display module comprises a cover plate 1, an LCD module 2 is installed on one side of the cover plate 1, a blind hole 21 is arranged on the LCD module 2, a hot melting point glue 22 is arranged on the periphery of the blind hole 21, the LCD module 2 comprises an upper polarizing sheet 23, an upper glass sheet 24, a lower glass sheet 25 and a lower polarizing sheet 26, wherein the upper polarizing sheet 23, the upper glass sheet 24, the lower glass sheet 25 and the lower polarizing sheet 26 are sequentially attached to form the LCD module 2, and the blind hole 21 is arranged on the lower polarizing sheet 26.

[0058] The double-sided adhesive 3 has a strong adhesive side 31 and a weak adhesive side 32, and the double-sided adhesive 3 is attached to the edge of the blind hole 21 on the LCD module 2 through the weak adhesive side 32.

[0059] The protection film 4 is attached to the double-sided adhesive 3 through the strong adhesive side 31.

[0060] In the embodiment, the two sides of the double-sided adhesive 3 are designed as adhesive surfaces with different adhesion, and the weak adhesive side 32 is attached to the blind hole 21, so that in the subsequent tearing process, the protection film 4 will separate from the surface of the polarizing sheet together with the double-sided adhesive 3 due to the attachment of the strong adhesive side 31 of the double-sided adhesive 3 to the protection film 4, so the double-sided adhesive 3 will not separate from the protection film 4 in the tearing process, and the weak adhesive side 31 will not be left on the polarizing sheet.

[0061] Please refer to Figure 3The double-sided adhesive 3 has an opening 33 and is arranged corresponding to the blind hole 21. Through the design of the opening 22, the blind hole in the lower polarizer 26 is exposed, and the curing of the hot-melt point glue 22 in the blind hole 21 is not affected.

[0062] The opening protection film for the display module provided in Embodiment 1 is further optimized. Specifically, as shown in Figure 6 and Figure 7 The protection film 4 has a broken line 41 at the position corresponding to the opening 33. Since the hot-melt point glue 22 is moisture-cured, it needs to be in contact with the moisture in the air to be fully cured. Therefore, the broken line 41 is designed in this embodiment.

[0063] Through the design of the broken line 41, when the protection film 4 is pasted on the strong adhesive surface 31 to form protection for the blind hole 21, a channel for the external air to interact with the blind hole 21 is left, which ensures the flow of air and meets the curing requirement of the hot-melt point glue 22.

[0064] As a further optimization of this embodiment, the broken line 41 is a cross-shaped broken line. The broken line 41 in this embodiment is a cross-shaped broken line as shown in Figure 6 .

[0065] As a further optimization of this embodiment, the broken line 41 is a parallel broken line. The broken line 41 in this embodiment is a parallel broken line as shown in Figure 7 .

[0066] As mentioned above, the cross-shaped broken line and the parallel broken line are both to realize the air exchange inside the protection film 4 to meet the curing requirement of the hot-melt point glue 22.

[0067] The opening protection film for the display module provided in Embodiment 2 is further optimized. As shown in Figure 8 , the protection film 4 has a fitting end 42 and a tearable end 43

[0068] The fitting end 42 is an arc surface and coincides with the edge of the double-sided adhesive 3.

[0069] The end of the fitting end 42 is an arc surface to coincide with the edge of the double-sided adhesive 3. Through the structural design of the arc surface, the use of the protection film 4 is reduced, the production cost is reduced, and the fitting end 42 can be contrasted with the tearable end 43. Thus, in the subsequent tearing of the protection film 4, the operator can quickly understand the tearing position through the contrast between the fitting end 42 and the tearable end 43, which is convenient for actual use.

[0070] The opening protection film for the display module provided in Embodiment 3 is further optimized. As shown in Figure 8 , the two sides of the tearable end 43 both have an arc chamfer 430.

[0071] Through the design of the arc chamfer 430, the edge of the protective film 4 can be arc transitioned, so compared with the protective film without chamfering, the situation of too sharp corner causing scratching is avoided, and since the arc design, the force of the contact surface during contact with external objects can be dispersed, by dispersing the contact force, the situation of the protective film 4 being easily lifted and falling due to excessive force is reduced, and the firmness of the protective film 4 is improved.

[0072] The opening protective film for display module provided in Embodiment 4 is further optimized, as shown in Figure 9 and Figure 10 A triangular gap 431 is cut between the two arc chamfers 430;

[0073] The easy-to-tear end 43 is further cut with a separation slit 432 at a position close to the triangular gap 431, and the separation slit 432 and the easy-to-tear end 43 are in communication with each other;

[0074] Through the design of the separation slit 432, the easy-to-tear end 43 can be separated into two parts, so that during subsequent tearing of the protective film 4, one of the arc chamfers 430 can be pressed, so that the two arc chamfers 430 will be staggered in angle, and the tearing of the protective film 4 is facilitated by the staggering.

[0075] The use process of the opening protective film for display module provided by the utility model is as follows: after full pasting of the blind hole project product, hot melt point glue 22 is set on the periphery of the lower polarizing plate 26, to prevent light leakage at the edge of the lower polarizing plate 26 from affecting the use of the camera, after the hot melt point glue 22 is set, double-sided adhesive 3 is pasted on the blind hole 21, so that the weak adhesive surface 32 of the double-sided adhesive 3 is pasted on the lower polarizing plate 23, and the opening 33 on the double-sided adhesive 3 corresponds to the blind hole 21, then the protective film 4 is pasted on the strong adhesive surface 31 of the double-sided adhesive 31, so that the protective film 4 can protect the opening, and since the double-sided adhesive 3 is pasted on the lower polarizing plate 26 through the weak adhesive surface 32, compared with the traditional pasting method of the protective film with a pasting layer, the situation of glue remaining on the surface of the lower polarizing plate 26 is effectively avoided, and before pasting, the protective film 4 is designed with a breaking line 41, so that the air flow on both sides of the protective film 4 is ensured, to meet the actual curing needs of the hot melt point glue 22.
