Technical Field

[0001] The utility model relates to the field of display screens, in particular to a display module capable of self-curing glue dispensing. Background Art

[0002] With the development of the automobile industry, the driving experience is constantly improving, and the use of large-size LCD screens for vehicle-mounted instruments is very popular. In the prior art, an instrument display screen is assembled from a cover plate, optical glue, FOG, sheet metal backlight, connecting glue, instrument middle frame, etc. Due to the large size of this structure, the vehicle-mounted module strength requirements are high, and the connection between the cover plate and the backlight is relatively narrow, so the connecting glue between the cover plate and the sheet metal backlight cannot use VHB, and can only be connected with RTV glue or hot melt glue. However, these two types of glue require a certain curing time after being applied. Therefore, the glue application and curing between the cover plate and the sheet metal backlight require matching a large number of curing fixtures, and the production efficiency is low.

[0020] Backlight housing 10 , panel 20 , display screen 30 , rigid sheet 40 , instrument middle frame 50 . DETAILED DESCRIPTION

[0021] 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.

[0022] This application proposes a display module that can self-curing glue dispensing, please refer to Figure 1, including: a backlight assembly, a panel 20 and a display screen 30. The panel 20 is a touch screen or a cover plate. If the panel 20 is a cover plate, the display module is a display device that displays a picture. If the panel 20 is a touch screen, the display module is a touch-sensitive display module. The backlight assembly includes a backlight shell 10 and a backlight source. The backlight shell 10 is recessed with a groove, and the backlight source is arranged on the side of the groove. The backlight shell 10 covers the panel 20 to form a receiving cavity. The receiving cavity is used to accommodate components such as the display screen 30 and the optical film group. The optical module can make the light of the backlight source more uniform. The display screen 30 is arranged in the receiving cavity, and the backlight shell 10 is provided with a plurality of rigid sheets 40 with double-sided adhesiveness on the covering surface with the panel 20. One side of the rigid sheet 40 is bonded to the backlight shell 10 , and the other side is bonded to the panel 20 , so that the rigid sheet 40 bonds and positions the backlight shell 10 and the panel 20 , so that the glue between the backlight shell 10 and the panel 20 is cured without using a curing fixture, which greatly improves production efficiency.

[0023] The rigid sheet 40 is a PET sheet.

[0024] Furthermore, the number of PET sheets is 6 to 12 sheets, and the more the number of PET sheets is, the better the positioning effect is.

[0025] Furthermore, the number of the PET sheets is 10 sheets.

[0026] As one of the preferred embodiments, the PET sheet is evenly arranged on the covering surface of the backlight shell 10 and the panel 20, so that the fixing effect between the backlight shell 10 and the panel 20 is similar, avoiding the fixed positioning effect from being concentrated in one place, and preventing the backlight shell 10 and the panel 20 from shifting.

[0027] Furthermore, the size of the PET sheet is 2.0*20 mm, and is attached to the edge of the backlight cover 10 .

[0028] As one of the preferred embodiments, the PET sheet is black to prevent light emitted from the backlight assembly from leaking and avoid insufficient brightness of the display screen 30.

[0029] Furthermore, the height of the PET sheet is 0.3 mm to 1.2 mm, so that the glue point height between the backlight housing 10 and the panel 20 is high enough, and the adhesion between the two is strong enough, thereby improving the reliability of the connection between the two.

[0030] Please refer again Figure 1 The display module with self-curing dispensing glue also includes a meter middle frame 50. The meter middle frame 50 is sleeved on the backlight shell 10. The meter middle frame 50 is used to protect the components in the backlight shell 10, such as the display screen, the backlight assembly and the optical film group, and the meter middle frame 50 is bonded to the panel 20 to fix the meter middle frame 50. In addition, the display screen 30 is a FOG liquid crystal screen.

[0031] 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.
