Description

Technical Field

[0001] This utility model relates to the field of light-shielding technology for photosensitive holes, and more specifically, to a Mylar structure for light-shielding photosensitive holes of a display screen. Background Technology

[0002] With the rapid development of display technology, the manufacturing precision and performance requirements of displays are increasing day by day. As a key component of the display, the design and manufacturing quality of the photosensitive hole directly affects the overall performance and user experience of the display. However, in the actual production process, a common problem is backlight leakage. This problem will seriously affect the accuracy and sensitivity of the photosensitive hole, and thus have an adverse effect on the overall display effect of the display.

[0003] To ensure the proper functioning of the display screen's photosensitive aperture and reduce the impact of backlight leakage on it, light-shielding material is typically applied to the side and part of the back of the backlight corresponding to the photosensitive aperture on the cover plate. However, traditional light-shielding materials are prone to air bubbles during application and lack sufficient flexibility, resulting in poor application and impacting the overall competitiveness of the product. Therefore, we have proposed an improvement: a Mylar structure for light-shielding the display screen's photosensitive aperture. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is that the light-blocking material is prone to air bubbles during the application process and has insufficient softness, resulting in poor application effect.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A Mylar structure for shielding the photosensitive hole of a display screen includes: a Mylar sheet with a plurality of through holes; the positions of the through holes correspond to the positions of the photosensitive holes of the cover plate, and the Mylar sheet does not cover the photosensitive area of ​​the cover plate when it is attached.

[0007] Through holes are designed at the bending and attaching positions of the Mylar sheet to reduce the resistance when bending the Mylar sheet. In the past, Mylar sheets were of uniform material, which required a large amount of external force when bending and was prone to wrinkles. The presence of through holes makes the bending area more flexible, allowing operators to attach the Mylar sheet to the target position more easily, reducing the skill requirements of the operators and improving the operability of the bonding work.

[0008] The through-hole plays a crucial role in promoting air venting. During the bonding process, if there is air between the Mylar film and the bonding surface, air bubbles will form. These air bubbles not only affect the aesthetics of the display screen but may also cause light to refract or scatter at the air bubbles, interfering with the normal operation of the photosensitive element. The through-hole can effectively guide air out, reduce the formation of air bubbles, and ensure that the Mylar film and the bonding surface are tightly bonded, thereby improving the bonding quality and ensuring the display screen's display effect and light-sensing performance.

[0009] Because the through holes increase the flexibility of the bending parts and promote air venting, rework caused by wrinkles and air bubbles during the bonding process is reduced. Operators do not need to repeatedly adjust the position of the Mylar or re-bond it, which shortens the bonding time, improves the overall production efficiency, and reduces the production cost.

[0010] As an improvement of this utility model, the through hole is located at the bend when the Mylar sheet is bonded.

[0011] As an improvement of this utility model, the Mylar sheet is used to adhere to the backlight side and back of the cover plate corresponding to the light-sensing hole.

[0012] As an improvement of this utility model, the Mylar sheet forms an L-shaped structure at the bend when it is bonded.

[0013] As an improvement of this utility model, the Mylar sheet is made of black polyester film material with a thickness of 0.05-0.15mm.

[0014] As an improvement of this utility model, the size of the through hole is smaller than the size of the photosensitive hole in the cover plate.

[0015] As an improvement of this utility model, one side of the Mylar sheet is provided with a double-sided adhesive layer, which is used for bonding the Mylar sheet.

[0016] As an improvement of this utility model, release paper is attached to the side of the double-sided adhesive layer away from the Mylar film.

[0017] As an improvement of this utility model, the Mylar sheet is coated with a scratch-resistant and wear-resistant coating on the side away from the double-sided adhesive layer. The scratch-resistant and wear-resistant coating is a polyurethane coating with a thickness of 0.005-0.01mm, which improves the durability of the Mylar sheet.

[0018] As an improvement of this utility model, the shape of the through hole is any one of circular, elliptical, rectangular or polygonal.

[0019] Compared with the prior art, the embodiments of this utility model have the following advantages:

[0020] To address the issues of air bubbles and insufficient flexibility in existing light-shielding materials during application, resulting in poor adhesion, this application designs through holes at the bending points in the Mylar sheet. This increases the flexibility of the bent portion of the Mylar sheet, facilitating adhesion. Furthermore, the through holes promote air release during the Mylar sheet application process, reducing the occurrence of air bubbles and improving the efficiency and accuracy of the application.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The reference herein to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] As described in the background art, in order to ensure the normal operation of the display screen's photosensitive hole and reduce the impact of backlight leakage on the photosensitive hole, it is usually necessary to attach a light-shielding material to the side of the backlight corresponding to the photosensitive hole on the cover plate and part of the back. However, traditional light-shielding materials are prone to air bubbles during the attachment process and lack flexibility, resulting in poor attachment effect and thus affecting the overall competitiveness of the product.

[0029] To solve this technical problem, this utility model provides a Mylar structure for blocking the light-sensitive hole of a display screen.

[0030] For details, please refer to Figures 1-4 The Mylar structure for shielding the light-sensitive hole of the display screen specifically includes:

[0031] Mylar film 1 has several through holes 101; the position of the through holes 101 corresponds to the position of the photosensitive hole of the cover plate, and does not cover the photosensitive area of ​​the cover plate when the Mylar film 1 is attached.

[0032] The Mylar structure for shielding the photosensitive hole of the display screen provided by this utility model increases the flexibility of the bent part of the Mylar sheet 1 by designing a through hole 101 at the position where the Mylar sheet 1 needs to be bent and attached, making it easier to attach. In addition, the through hole 101 can also promote the air release during the attachment process of the Mylar sheet 1, reduce the problem of air bubbles after the Mylar sheet 1 is attached, and improve the efficiency and accuracy of attachment.

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0036] Embodiment 1 of the Mylar structure for blocking the light-sensitive hole of the display screen of this utility model

[0037] For details, please refer to Figures 1-4 The Mylar structure for shielding the photosensitive hole of the display screen of this utility model includes: Mylar sheet 1, on which a plurality of through holes 101 are formed; the position of the through holes 101 corresponds to the position of the photosensitive hole of the cover plate, and does not cover the photosensitive hole of the cover plate when the Mylar sheet 1 is attached.

[0038] A through hole 101 is designed at the bending and attaching position of Mylar sheet 1, which reduces the resistance when Mylar sheet 1 is bent. In the past, Mylar sheet was of uniform material, and it required a large external force when bent and was prone to wrinkles. The presence of through hole 101 makes the bending part more flexible, and the operator can attach Mylar sheet 1 to the target position more easily, reducing the skill requirements of the operator and improving the operability of the bonding work.

[0039] The through-hole 101 plays a crucial role in promoting air venting. During the bonding process, if there is air between the Mylar sheet 1 and the bonding surface, air bubbles will form. These air bubbles not only affect the aesthetics of the display screen but may also cause light to refract or scatter at the air bubbles, interfering with the normal operation of the photosensitive element. The through-hole 101 can effectively guide air out, reduce the generation of air bubbles, and ensure that the Mylar sheet 1 is tightly bonded to the bonding surface, thereby improving the bonding quality and ensuring the display effect and light-sensing performance of the display screen.

[0040] Because the through-hole 101 increases the flexibility of the bending parts and promotes air venting, it reduces rework caused by wrinkles and air bubbles during the bonding process. Operators do not need to repeatedly adjust the position of Mylar 1 or re-bond it, which shortens the bonding time, improves the overall production efficiency, and reduces the production cost.

[0041] Furthermore, the through hole 101 is located at the bend when the Mylar sheet 1 is bonded. When the Mylar sheet 1 is bent, the bend bears the greatest stress. The presence of the through hole 101 can effectively disperse the stress, reduce the stress concentration phenomenon generated during the bending process, and reduce the breakage or damage of the Mylar sheet 1 at the bend, thereby ensuring that the Mylar sheet 1 can be bent and bonded smoothly.

[0042] Furthermore, Mylar sheet 1 is used to adhere to the backlight side and back of the cover plate corresponding to the photosensitive hole; Mylar sheet 1 adheres to the backlight side and back of the cover plate corresponding to the photosensitive hole, which can form a relatively closed light-blocking environment. Light coming from different directions will be blocked by Mylar sheet 1, effectively reducing the impact of light on the photosensitive hole.

[0043] Furthermore, such as Figure 1 As shown, the Mylar sheet 1 forms an L-shaped structure at the bend when it is bonded; the L-shaped structure can fit the shape of the backlight side and back, and the backlight usually has two different planes, the side and the back, and the L-shaped Mylar sheet 1 can cover both planes at the same time.

[0044] Embodiment 2 of the Mylar structure for blocking the light-sensitive hole of the display screen of this utility model

[0045] Furthermore, the Mylar structure for shielding the photosensitive hole of this utility model is further improved by using a black polyester film 1 with a thickness of 0.05-0.15mm. The black polyester film has an extremely high light absorption rate, which can effectively block light of various wavelengths. In the application of shielding the photosensitive hole of the display screen, it can ensure that light does not pass through the Mylar film 1 into the photosensitive hole, ensuring that the photosensitive element can accurately sense the external light, reducing display abnormalities caused by light interference, and improving the display quality and stability of the display screen. The polyester film has a certain degree of flexibility, which allows the Mylar film 1 to better adapt to different bonding surface shapes during the bonding process, reducing bonding gaps and improving the shielding effect.

[0046] Furthermore, the size of the through hole 101 is smaller than the size of the photosensitive hole in the cover plate; designing the through hole 101 to be smaller than the size of the photosensitive hole in the cover plate can effectively reduce the amount of light entering the photosensitive hole through the through hole 101.

[0047] Furthermore, one side of the Mylar film 1 is provided with a double-sided adhesive layer, which is used for bonding the Mylar film 1. The double-sided adhesive layer provides a simple and quick bonding method. The operator only needs to put the side of the Mylar film 1 with the double-sided adhesive layer into contact with the target bonding surface and apply a certain pressure to complete the bonding, without the need for additional adhesives or complicated bonding equipment.

[0048] Furthermore, a release paper is attached to the side of the double-sided adhesive layer away from the Mylar film 1; the release paper can effectively protect the adhesiveness of the double-sided adhesive layer and ensure that the double-sided adhesive layer can play a good adhesive role when bonding is required.

[0049] Furthermore, the Mylar film 1 is coated with a scratch-resistant and wear-resistant coating on the side away from the double-sided adhesive layer. The scratch-resistant and wear-resistant coating is a polyurethane coating with a thickness of 0.005-0.01mm. Applying a scratch-resistant and wear-resistant coating to the surface of the Mylar film 1 can effectively resist scratches from external objects. During the installation, use and maintenance of the display screen, it may come into contact with other objects, such as tools and fingers. The scratch-resistant coating can reduce scratches on the surface of the Mylar film 1, keep its appearance clean, and at the same time reduce light leakage caused by scratches, ensuring light-shielding performance.

[0050] During bending, the polyurethane coating of Mylar sheet 1 can deform synchronously with it, avoiding cracking or peeling, while also meeting the requirements for scratch resistance.

[0051] Embodiment 3 of the Mylar structure for blocking the light-sensitive hole of the display screen of this utility model

[0052] Furthermore, in this utility model, the shape of the through hole 101 can be any one of a circle, an ellipse, a rectangle, or a polygon; the choice of multiple through hole 101 shapes provides greater flexibility in the design of the Mylar sheet 1.

[0053] For ease of understanding, in the diagram, point A is marked as backlight, point B as cover plate, and point C as photosensitive hole. When bonding, clean the bonding surfaces of the backlight's sides and back, removing dust and oil. Peel off the release paper from the double-sided adhesive layer of Mylar film 1. Align the folded part of Mylar film 1 with the edge of the backlight, ensuring the projection position of the through hole 101 is offset from the photosensitive hole. Gently press the back bonding portion of Mylar film 1 onto the back of the backlight, slowly pressing from the center to the edge to expel air through the through hole 101. Bend Mylar film 1 along the fold towards the backlight side, gradually pressing the side portion to ensure complete contact and bonding between the double-sided adhesive and the side. After bonding, it should look like... Figure 3 and Figure 4 As shown, the position of the through hole 101 is offset from the position of the photosensitive hole during bonding.
