Description

Technical Field

[0001] This utility model relates to the field of GIP circuit protection technology, and in particular to a protection structure for GIP circuits in display modules. Background Technology

[0002] like Figure 7 Due to high reliability requirements, the backlight of the vehicle shown has foam 1-3 (used for buffering to avoid uneven display) and a plastic frame 1-4 (used to improve the reliability of the backlight) between the TFT glass 1-1 and the backlight emitting area 1-2. The distance between the TFT glass 1-1 and the backlight emitting area 1-2 is relatively large, generally about 1.5mm. To avoid viewing the TFT display viewing area 1-6 at an angle, we generally require the backlight emitting area 1-2 to be 0.8~1.2mm larger on each side than the TFT display viewing area 1-6. However, the GIP circuit 1-7 is only about 0.2mm away from the edge of the TFT display viewing area 1-6. This will cause a large area of ​​the GIP circuit 1-7 to be illuminated by the backlight. The larger the area of ​​the GIP circuit 1-7 that is illuminated, the higher the probability of quality problems. Therefore, a protection structure for the GIP circuit in the display module is proposed. Utility Model Content

[0003] Therefore, it is necessary to provide a protective structure for the GIP circuit in the display module to address the above-mentioned technical problems. The structure involves designing a light-shielding element on one side of the buffer element, so that the end of the light-shielding element extends to the edge of the display area, thus providing effective light protection for the GIP circuit.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A protective structure for a GIP circuit within a display module includes: a frame on which a TFT glass and a backlight module are respectively mounted on opposite sides; a CF glass is also attached to the outer side of the TFT glass; and a GIP circuit is provided at the edges of the CF glass and the TFT glass on opposite sides. The structure is characterized by further including a buffer element disposed between the TFT glass and the backlight module, and a light-shielding element on the surface of the buffer element.

[0006] The end of the light-shielding element extends toward the display area of ​​the TFT glass to partially block the backlight emitting area, thereby forming a light-shielding protection for the GIP circuit.

[0007] Furthermore, the inner end of the light-shielding element extends to the outer edge of the display area.

[0008] Furthermore, the inner end of the light-shielding element is 0.2 millimeters away from the display area;

[0009] The inner end of the GIP circuit is also 0.2 millimeters away from the display area.

[0010] Furthermore, the light-shielding element is a black light-shielding film.

[0011] Furthermore, the buffer element has a receiving groove on the side facing the TFT glass, the black light-shielding film is pasted in the receiving groove, and the black light-shielding film is flush with the surface of the buffer element.

[0012] Furthermore, the portion of the light-shielding element located outside the receiving groove is provided with a thickened light-shielding part, and the thickened light-shielding part and the light-shielding element are designed as an integral structure.

[0013] Furthermore, a right-angle step is formed between the top of the thickened light-shielding part and the light-shielding element, and the right-angle step is fitted to the bottom of the buffer element.

[0014] Furthermore, a support portion is also connected to one side of the thickened light-shielding portion;

[0015] The bottom end of the support portion is fitted to the bottom end of the buffer element.

[0016] Furthermore, the support portion is triangular.

[0017] Furthermore, the buffer element is double-sided adhesive foam, with one side of the double-sided adhesive foam adhered to the adhesive frame and the other side adhered to the surface of the TFT glass.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The protective structure for the GIP circuit in the display module provided by this utility model is designed with a light-shielding element on one side of the buffer element, so that the end of the light-shielding element extends to the edge of the display area. In this way, the light emitted from the backlight emitting area toward the GIP can be blocked by the light-shielding element first, thereby forming a light-shielding protection for the GIP circuit. At the same time, since the light-shielding element does not extend into the display area, it will not affect the normal display effect of the TFT glass.

[0020] The design of the receiving groove allows for the pre-embedded installation of the buffer element, thus avoiding further increasing the distance between the TFT glass and the backlight emitting area. At the same time, the design of the thickened light-shielding part further increases the light-shielding area, achieving a better light-shielding effect.

[0021] The right-angle step design provides support for the thickened light-shielding part. In addition, the support structure further increases the support strength of the thickened light-shielding part. Since the black light-shielding film is integrated with the thickened light-shielding part, it provides an effective support base for the black light-shielding film, further ensuring its stability in blocking the light source of the backlight area.

[0036] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0037] As described in the background section, automotive backlights require high reliability, so there is foam 1-3 (used for buffering to avoid uneven display) and a frame 1-4 (used to improve backlight reliability) between the TFT glass 1-1 and the backlight emitting area 1-2. The distance between the TFT glass 1-1 and the backlight emitting area 1-2 is relatively far, generally about 1.5mm. To avoid viewing the TFT display viewing area 1-6 at an angle, we generally require the backlight emitting area 1-2 to be 0.8~1.2mm larger on each side than the TFT display viewing area 1-6. However, the GIP circuit 1-7 is only about 0.2mm away from the edge of the TFT display viewing area 1-6. This will cause a large area of ​​the GIP circuit 1-7 to be illuminated by the backlight. The larger the area of ​​the GIP circuit 1-7 that is illuminated, the higher the probability of quality problems.

[0038] To solve this technical problem, this utility model provides a protection structure for GIP circuits within a display module, which is applied to GIP circuit protection.

[0039] For details, please refer to Figures 1-7 As shown, the protection structure used to display the GIP circuit within the display module specifically includes:

[0040] The device includes a frame 1, on which TFT glass 2 and a backlight module 3 are respectively mounted on both sides. CF glass 4 is also attached to the outer side of the TFT glass 2. GIP circuit 21 is provided at the edges of the CF glass 4 and the TFT glass 2 on opposite sides. The device is characterized by further including a buffer element 5, which is disposed between the TFT glass 2 and the backlight module 3. A light-shielding element 6 is also provided on the surface of the buffer element 5.

[0041] The end of the light-shielding element 6 extends toward the display area 22 of the TFT glass 2 to partially block the backlight emitting area 31, thereby forming a light-shielding protection for the GIP circuit 21.

[0042] The protective structure for the GIP circuit in the display module provided by this utility model is designed with a light-shielding element 6 on one side of the buffer element 5, so that the end of the light-shielding element 6 extends to the edge of the display area 22. In this way, the light emitted from the backlight emitting area 31 toward the GIP circuit 21 can be blocked by the light-shielding element 6, thereby forming a light-shielding protection for the GIP circuit 21. At the same time, since the light-shielding element 6 does not extend into the display area 22, it will not affect the normal display effect of the TFT glass 2.

[0043] 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.

[0044] 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.

[0045] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0046] Please refer to Figure 1 and Figure 2 As shown, a protective structure for GIP circuits within a display module includes a frame 1, on which TFT glass 2 and a backlight module 3 are respectively mounted. A CF glass 4 is also attached to the outer side of the TFT glass 2. A GIP circuit 21 is provided at the edge of the CF glass 4 and the TFT glass 2 on opposite sides. The structure is characterized by further including a buffer element 5, which is disposed between the TFT glass 2 and the backlight module 3. A light-shielding element 6 is also provided on the surface of the buffer element 5.

[0047] The end of the light-shielding element 6 extends toward the display area 22 of the TFT glass 2 to partially block the backlight emitting area 31, thereby forming a light-shielding protection for the GIP circuit 21.

[0048] The inner end of the light-shielding element 6 extends to the outer edge of the display area 22.

[0049] like Figure 2As shown, through the above structural design, the backlight module 3 emits light to the left through the backlight emitting area 31. Since the width of one side of the backlight emitting area 31 is greater than the width of the display area 22 in the TFT glass 2, some light will shine towards the GIP circuit 21. Since the light-shielding element 6 is designed on the right side of the GIP circuit in this embodiment, the light will be blocked by the light-shielding element 6 when it shines on the GIP circuit 21, thereby avoiding the GIP circuit 21 from being directly irradiated, which is beneficial to achieving light protection for the GIP circuit 21.

[0050] In this embodiment, the inner end of the light-shielding element 6 is 0.2 mm away from the display area 22, and the inner end of the GIP circuit 21 is also 0.2 mm away from the display area 22.

[0051] Therefore, the inner end of the light-shielding element 6 is on the same horizontal line as the inner end of the GIP circuit 21, so it can effectively block most of the light shining towards the GIP circuit 21, further improving the protective effect of the protective structure.

[0052] The light-shielding element 6 is a black light-shielding film. The black light-shielding film itself has a certain rigidity and is not extremely soft. Therefore, when it is attached to the surface of the buffer element 5, the light-shielding element 6 can provide effective support and ensure its own light-shielding extension.

[0053] The protection structure for the GIP circuit within the display module provided in Embodiment 1 is further optimized, specifically, as follows: Figure 4 As shown, the buffer element 5 has a receiving groove 51 on the side facing the TFT glass 2, and the black light-shielding film is pasted in the receiving groove 51, and the black light-shielding film is flush with the surface of the buffer element 5.

[0054] The design of the receiving groove 51 allows for the pre-embedded installation of the buffer element 5, thus avoiding further increasing the distance between the TFT glass 2 and the backlight emitting area 31.

[0055] The portion of the light-shielding element 6 located outside the receiving groove 51 is provided with a thickened light-shielding part 61, and the thickened light-shielding part 61 and the light-shielding element 6 are designed as an integral structure.

[0056] A right-angle step 62 is formed between the top of the thickened light-shielding part 61 and the light-shielding element 6, and the right-angle step 62 is fitted to the bottom of the buffer element 5.

[0057] like Figure 5As shown, a right-angled step 62 is formed between the thickened light-shielding part 61 and the connection of the light-shielding element 6. When the light-shielding element 6 is embedded in the receiving groove 51, the right-angled step 62 can form a support state with the edge of the buffer element 5, thereby providing a certain support effect for the thickened light-shielding part 61. The thickened light-shielding part 61, which is supported, also provides effective support for the black light-shielding film, ensuring the stability of the light-shielding element 6 in the light-shielding state.

[0058] The surface of the light-shielding element 6 is provided with an adhesive layer, which can be used to bond the light-shielding element 6 to the TFT glass 2 or the buffer element 5.

[0059] The protection structure for the GIP circuit within the display module provided in Embodiment 1 or 2 is further optimized, such as... Figure 5 and Figure 6 As shown, a support part 63 is also connected to one side of the thickened light-shielding part 61, wherein the bottom end of the support part 63 is fitted to the bottom end of the buffer element 5.

[0060] The support part 63 is triangular. Through the design of the support part 63, the top of the support part 63 can form a support with the buffer element 5. The support part 63, which is supported, can provide support for the thickened light-blocking part 61 and the black light-blocking film, thereby ensuring the stability of the light-blocking element 6 when it blocks light and avoiding the light-blocking effect caused by bending due to the straight body.

[0061] The buffer element 5 is double-sided adhesive foam, with one side of the double-sided adhesive foam being attached to the adhesive frame 1 and the other side being attached to the surface of the TFT glass 2.

[0062] The process of using the protective structure for the GIP circuit in the display module provided by this utility model is as follows: A receiving groove 51 is designed on the surface of the buffer element 5, and then the light-shielding element 6 is embedded in the buffer element 5, so that the inner end of the light-shielding element 6 extends toward the display area 22 of the TFT glass 2, and the distance between the inner end of the light-shielding element 6 and the display area 22 is kept the same as the distance between the GIP circuit 21 and the display area 22. In this way, the light emitted by the backlight emitting area 31 will be blocked by the light-shielding element 6 and avoid contact with the GIP circuit 21.

[0063] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0064] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
