Description

Technical Field

[0001] The utility model relates to the field of display screens, in particular to a vehicle-mounted display module capable of reducing small black edges. Background Art

[0002] In the prior art, one solution is that the connection between the backlight rubber frame, the vehicle housing and the cover plate is at the edges of the cover plate. The fitting width between the backlight rubber frame and the cover plate is more than 3mm, and the width of the cover plate fixed to the vehicle housing is more than 4mm, otherwise it will not be stable. Therefore, the connection width between the backlight rubber frame, the vehicle housing and the cover plate is more than 7mm, resulting in a large black edge on the display, affecting the visual effect. Another solution is that there is no need for a cover plate, and the vehicle housing directly presses on the edge of the TFT display screen. The TFT display screen frame of this solution is smaller, but this structure has no cover plate and cannot be used for touch control. In addition, the surface height of the vehicle housing and the TFT display screen is inconsistent, affecting the visual effect. Utility Model Content

[0021] The cover plate assembly 10 , the annular groove 11 , the first cover plate 12 , the second cover plate 13 , the backlight assembly 20 , the TFT display screen 30 , the adhesive layer 40 and the vehicle-mounted housing 50 . DETAILED DESCRIPTION

[0022] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0023] This application proposes a vehicle display module that can reduce the small black border. Figure 1, including: a cover assembly 10, a backlight assembly 20, a TFT display screen 30, an adhesive layer 40 and a vehicle-mounted housing 50, wherein the backlight assembly 20 is used to illuminate the TFT display screen 30 and the cover assembly 10. The TFT display screen 30 is arranged between the cover assembly 10 and the backlight assembly 20, and a ring is arranged on the edges of the cover assembly 10, and the width of the ring groove 11 is 1.0 mm. The vehicle-mounted housing 50 is bonded to the ring groove 11 through the adhesive layer 40, and the backlight assembly 20 is bonded to the side of the cover assembly 10 away from the ring groove 11 through the adhesive layer 40. Compared with the prior art, the black edge is greatly reduced from more than 7 mm to 1 mm, and the height of the cover is consistent with that of the vehicle-mounted housing 50, so the touch function is retained and the visual effect is optimized. Preferably, the adhesive layer 40 is double-sided adhesive foam.

[0024] It should be noted that the vehicle housing 50 is bonded in the annular groove 11, and on the upper surface of the cover assembly 10, the backlight assembly 20 is bonded below the annular groove 11 and bonded around the edges of the lower surface of the cover assembly 10. The cover assembly 10 is provided with an annular groove 11 on its edges by cutting, so that the cover assembly 10 is integrated to reduce the assembly process. In one embodiment, please refer to Figure 2 The cover plate assembly 10 includes a first cover plate 12, a second cover plate 13 and optical glue. The first cover plate 12 is attached to the second cover plate 13 by optical glue. In order to set the stepped annular groove 11, the length and width of the first cover plate 12 are correspondingly smaller than the length and width of the second cover plate 13. This design does not require expensive automated equipment to operate when the product is sampled or not mass-produced, saving costs. Furthermore, the length and width of the TFT display screen 30 are consistent with the length and width of the first cover plate 12. The display area in the first cover plate 12 can display a complete picture, and the picture displayed by the TFT display screen 30 will not be blocked by the vehicle-mounted housing 50, resulting in incomplete picture display, thereby affecting the visual experience. Preferably, the optical glue is OCA glue or OCR glue. OCA glue and OCR glue are transparent and have extremely high light transmittance to avoid affecting the display effect.

[0025] The vehicle-mounted display module of the present application also includes an upper polarizer and a lower polarizer, and the TFT display screen 30 is arranged between the upper polarizer and the lower polarizer. The upper polarizer and the lower polarizer are used to remove excess reflections and reflections in the vehicle-mounted display module to enhance the contrast and clarity of the image. In one embodiment, the backlight assembly 20 includes a light source assembly, a backlight frame, and a light source refractive film layer. The light source assembly provides a light source for illumination, the light source refractive film layer is used to filter light, and the backlight frame is used to protect the light source assembly and the light source refractive film layer. The light source assembly and the light source refractive film layer are arranged on the backlight frame, and the light emitted by the light source assembly is refracted through the light source refractive film layer to adjust a better visual effect. Furthermore, the light source assembly is a plurality of LED lamps, and the LED lamp uses a cold light source, has little glare, no radiation, can protect the user's eyes, and has a long life. In addition, the backlight frame is a plastic frame.

[0026] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model 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 utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
