Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted modules, in particular to a display module capable of protecting a GIP circuit. Background Art

[0002] The existing vehicle-mounted module is roughly composed of accessories such as backlight module, TFT, OCA and cover plate. The display module is composed of CF glass and TFT glass. Usually, the vehicle-mounted module has a gate IC on the side. In order to narrow the edge and reduce costs, the gate IC is usually removed. After the gate IC is removed, it must be replaced with GIP circuits on both sides, such as Figure 6 As shown, the conventional GIP circuit 1-5 is designed on the TFT glass 1-2 and is located on both sides of the viewing area of ​​the TFT glass 1-2. However, the GIP circuit 1-5 will exhibit horizontal jitter and abnormality after being exposed to strong light from the bottom backlight 1-3. In order to ensure that the backlight 1-3 can fully illuminate the viewing area of ​​the CF glass 1-1 to avoid errors and other factors, the luminous area of ​​the backlight 1-3 is usually larger than the viewing area within the TFT glass 1-2. Therefore, the GIP circuit 1-5 will enter the luminous area of ​​the backlight 1-3. At the same time, the vehicle-mounted backlight 1-3 has a high brightness requirement. Therefore, the GIP circuit 1-5 is easily exposed to high brightness and malfunctions. Therefore, a display module that can protect the GIP circuit is proposed. Utility Model Content

[0003] Based on this, it is necessary to provide a display module that can protect the GIP circuit to address the above technical problems. The CF glass and TFT glass are swapped so that the GIP circuit is located above the BM ink, so that the BM ink can block the light of the GIP circuit.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A display module capable of protecting a GIP circuit, comprising:

[0006] Backlight module;

[0007] CF glass, which is attached to the backlight module;

[0008] TFT glass, which is attached to the surface of the CF glass, and GIP circuits are provided on both sides of the bottom of the TFT glass;

[0009] Wherein, BM ink areas are silk-screened on both sides of the top of the CF glass corresponding to the position of the GIP circuit, and the BM ink areas can form light-shielding protection for the GIP circuit.

[0010] Furthermore, a first visible area is formed between the GIP circuits on both sides of the TFT glass.

[0011] Furthermore, a second visible area is formed between the BM ink areas on both sides of the CF glass;

[0012] Wherein, the width of the second visible area is smaller than the width of the first visible area.

[0013] Furthermore, a cover plate is attached to the top of the TFT glass.

[0014] Furthermore, both sides of the bottom of the cover plate have ink areas;

[0015] A third visible area is formed between the ink areas on both sides.

[0016] Furthermore, the width of the third visible area is smaller than that of the first visible area, so as to provide shielding protection for the GIP circuit.

[0017] Furthermore, the width of the third visible area is smaller than that of the second visible area, and is used to shield the BM ink area.

[0018] Furthermore, an FPC is commonly connected between the backlight module and the TFT glass.

[0019] Furthermore, a protective film is attached to the top of the FPC, and one end of the protective film is attached to the surface of the TFT glass.

[0020] Furthermore, a pasting gap is reserved at the bottom of the cover plate for embedding and pasting one end of the protective film.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The display module provided by the present invention can protect the GIP circuit. The CF glass and the TFT glass are transposed so that the GIP circuit is located above the BM ink area. The BM ink area forms a light shield for the GIP circuit. In this way, when the backlight module is used for lighting, light cannot directly illuminate the bottom of the GIP circuit, thereby avoiding malfunction of the GIP circuit due to high-brightness illumination.

[0023] The design of the ink area on the cover can shield the top of the GIP circuit, effectively isolating it from external light, further protecting the GIP circuit.

[0024] Since the CF glass and TFT glass are designed to be transposed, the FPC needs to be bent during actual application. The design of the protective film can improve the stability of the connection at the FPC bending point. At the same time, the design of the pasting gap and the cover plate further ensure the stability of the protective film pasting. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0038] As described in the background technology, Figure 6 As shown, the GIP circuit 1-5 is designed on the TFT glass 1-2, on both sides of the viewing area of ​​the TFT glass 1-2. When the GIP circuit 1-5 is exposed to strong light from the bottom backlight 1-3, horizontal stripes and jitter will occur. In order to ensure that the backlight 1-3 can completely illuminate the viewing area of ​​the CF glass 1-1 to avoid errors and other factors, the luminous area of ​​the backlight 1-3 is usually larger than the viewing area in the TFT glass 1-2. Therefore, the GIP circuit 1-5 will enter the luminous area of ​​the backlight 1-3. At the same time, the vehicle-mounted backlight 1-3 has a high brightness requirement, so the GIP circuit 1-5 is easily exposed to high brightness and malfunctions.

[0039] In order to solve this technical problem, the present invention provides a display module that can protect the GIP circuit, which is applied to a vehicle-mounted display module.

[0040] Specifically, please refer to Figures 1-6 , the display module capable of protecting the GIP circuit specifically includes:

[0041] Backlight module 1;

[0042] CF glass 2, which is attached to the backlight module 1;

[0043] TFT glass 3, which is attached to the surface of the CF glass 2, and GIP circuits 31 are provided on both sides of the bottom of the TFT glass 3;

[0044] Wherein, BM ink areas 21 are screen-printed on both sides of the top of the CF glass 2 at positions corresponding to the GIP circuit 31 , and the GIP circuit 31 can be shielded by the BM ink areas 21 to form light shielding protection.

[0045] The display module provided by the present invention can protect the GIP circuit. The CF glass 2 and the TFT glass 3 are transposed so that the GIP circuit 31 is located above the BM ink area 21. The BM ink area 21 blocks light from the GIP circuit 31. In this way, when the backlight module 1 is used for lighting, light cannot directly illuminate the bottom of the GIP circuit, thereby preventing the GIP circuit from malfunctioning due to high-brightness exposure.

[0046] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0047] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0048] 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.

[0049] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown, a display module capable of protecting a GIP circuit comprises: a backlight module 1; a CF glass 2, which is attached to the backlight module 1; and a TFT glass 3, which is attached to the surface of the CF glass 2. GIP circuits 31 are provided on both sides of the bottom of the TFT glass 3. BM ink areas 21 are silk-screened on both sides of the top of the CF glass 2 at positions corresponding to the GIP circuits 31. The BM ink areas 21 shield the GIP circuits 31, thereby providing light shielding protection.

[0050] like Figure 3 As shown, a first visible area 32 is formed between the GIP circuits 31 on both sides of the TFT glass 3, and a second visible area 22 is formed between the BM ink areas 21 on both sides of the CF glass 2;

[0051] Through the cooperation of the first visible area 32 and the second visible area 22, when the backlight module 1 at the bottom emits light, the light can sequentially pass through the second visible area 22 and the first visible area 32, and finally act on the cover plate 4 to form a light-emitting display;

[0052] The width of the second visible area 22 is smaller than the width of the first visible area 32. Figure 3 As shown, the inner sides of the BM ink areas 21 on both sides extend outside the GIP circuit 31. Therefore, when the backlight module 1 emits light, the light will first be blocked by the BM ink area 21. Since the BM ink area 21 is not transparent, the GIP circuit 31 located above it will not be exposed to the light, thereby forming a light-shielding protection for the GIP circuit 31. Compared with the traditional module structure, it effectively avoids the malfunction of the GIP circuit 31 due to high-brightness exposure.

[0053] Based on Example 1, the GIP circuit 31 is further optimized. Specifically, in Example 1, a BM ink area 21 is added below the GIP circuit 31 to block the light emitted by the backlight module 1. However, in actual application, external light may directly illuminate the upper part of the GIP circuit 31, which is not conducive to the stable use of the GIP circuit 31. This embodiment solves this problem. The specific structure is as follows:

[0054] The display module capable of protecting the GIP circuit provided in Example 1 is further optimized. Specifically, Figure 3 and Figure 4 As shown, a cover plate 4 is attached to the top of the TFT glass 3, and ink areas 41 are provided on both sides of the bottom of the cover plate 4;

[0055] A third visible area 43 is formed between the ink areas 41 on both sides;

[0056] The ink area 41 is designed to shield and protect the area above the GIP circuit 31, thereby preventing external light from directly irradiating the surface of the GIP circuit 31 and affecting its stable use.

[0057] As a further optimization of this embodiment: the width of the third visible area 43 is smaller than the first visible area 32, so as to provide shielding protection for the GIP circuit 31;

[0058] Specifically, such as Figure 3 As shown, the width of the ink region 41 is greater than the width of the GIP circuit 31. Therefore, the width of the third visible region 43 formed between the two ink regions 41 is smaller than the width of the first visible region 32 formed between the two GIP circuits 31. In this way, when an image is displayed on the outside of the cover plate 4, the GIP circuit 31 is not only shielded from light but also covered by the ink region 41, thereby improving the overall appearance of the module.

[0059] As a further optimization of this embodiment: the width of the third visible area 43 is smaller than the second visible area 22, and is used to shield the BM ink area 21;

[0060] Specifically, such as Figure 3As shown, the width of the ink area 41 is larger than the width of the GIP circuit 31 and also larger than the width of the BM ink area 21. Therefore, the width of the third visible area 43 formed between the two ink areas 41 will be smaller than the width formed between the two BM ink areas 21. In this way, when observing from the outside of the cover plate 4, the GIP circuit 31 can be blocked and the BM ink area 21 below it can be covered at the same time, further ensuring the overall beauty of the module and avoiding the generation of misalignment at the edges of the BM ink area 21 and the GIP circuit 31 and between the GIP circuit 31 and the ink area 41, which affects the overall beauty.

[0061] The display module that can protect the GIP circuit provided in Example 1 or 2 is further optimized, such as Figure 4 and Figure 5 As shown, the backlight module 1 and the TFT glass 3 are connected with an FPC 5;

[0062] The conventional display module is arranged in the order of CF glass 1-1, TFT glass 1-2 and backlight 1-3 from top to bottom. Therefore, the FPC is directly connected to the corresponding backlight 1-3 and TFT glass 1-2. However, in this embodiment, in order to protect the GIP circuit 31, the positions of the CF glass 1-1 and the TFT glass 1-2 are swapped. In this way, the following is formed during the connection of the FPC 5. Figure 4 The bending arc surface shown has a large stress at the bending point, so a protective film 51 is provided to ensure the connection stability.

[0063] A protective film 51 is attached to the top of the FPC 5 , one end of which is attached to the surface of the TFT glass 3 , and a gap 44 is left at the bottom of the cover plate 4 for embedding and attaching one end of the protective film 51 ;

[0064] Specifically, after connecting the two ends of the FPC 5 to the corresponding TFT glass 3 and the backlight module 1 respectively, a protective film 51 can be pasted on the surface of the FPC 5, and then one end of the protective film 51 is laid on the surface of the TFT glass 3 to form a bond. In this way, the traction effect of the protective film 51 can ensure the stability of the connection end of the FPC 5, avoiding the problem of loose connection affecting subsequent use.

[0065] During the process of attaching one end of the FPC 5 to the surface of the TFF glass 3, care must be taken to ensure that the end of the protective film 5 does not extend beyond the position of the GIP circuit 31 below. A gap 44 can then be designed at the corresponding position of the cover plate 4 above. This allows the cover plate 4 to remain parallel to the TFT glass 3 after it is fastened to the surface of the TFF glass 3. Furthermore, the pressure from the cover plate 4 further enhances the stability of the protective film 51 after it is attached to the surface of the TFT glass 3.

[0066] The display module provided by the present invention, which can protect the GIP circuit, is used as follows: the CF glass 2 and the TFT glass 3 are transposed so that the GIP circuit 31 is located above the BM ink area 21. The BM ink area 21 forms a light shield for the GIP circuit 31. In this way, when the backlight module 1 is used for lighting, light cannot directly illuminate the bottom of the GIP circuit 31, thereby avoiding the malfunction of the GIP circuit 31 due to high-brightness illumination. Then, in conjunction with the design of the ink area 41 on the cover plate 4, the upper part of the GIP circuit 31 can be shielded, effectively isolating it from external light.
