[0021] The technical structure scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the utility model examples, and the described embodiments are only some of the embodiments of the utility model structure, not all the embodiments. The additional technical features of the utility model and its advantages will be more obvious in the following description, or can be understood through the specific practice of the utility model.

[0022] Reference Figures 1-5 The utility model provides a kind of integral type extremely narrow frame display screen structure, front design has conventional explosion-proof membrane 1, glass cover plate 2, OCA 3, liquid crystal glass 4, die casting backlight 6, PCBA 7, installation fixed support 8, plastic plug 10, structural glue 5 and fixed screw 9.

[0023] After glass cover plate 2 and die casting backlight 6 are assembled integrally, the fixing of PCBA 7 and the installation of plastic plug 10 are carried out.Installation fixed support 8 and PCBA 7 make fixed screw 9 fixed at the back of die casting backlight 6, after PCBA 7 is assembled, the installation and fixing of plastic plug 10 are carried out again, and the fixed mode is snap hook and screw.The appearance piece is integral type die casting backlight and glass cover plate.

[0024] The die casting backlight 6 is an integral structure, adopts narrow frame design, reserves glue dispensing groove, is convenient for guaranteeing that glue thickness and width are uniform after glue dispensing, and overflow phenomenon will not be generated.

[0025] As Figure 1 And 2 As shown in the utility model, it mainly has 10 main components, the relative position, connection, action fixed relationship between each component are as follows:

[0026] Explosion-proof membrane 1 and glass cover plate 2 are pasted and fixed using direct affixing mode.Glass cover plate 2 and liquid crystal glass 4 are fixed using full pasting OCA 3 (optical transparent glue), glass cover plate 2 and die casting backlight 6 are fixed using structural glue 5, installation fixed support 8 and PCBA 7 are fixed using screw 9.Plastic clips are clamped on the installation angle of die casting backlight.After assembly, plastic plug 10 is fixed using screw 9.Integral type die casting backboard 6 and explosion-proof membrane 1 and glass cover plate 2 are directly used as appearance of instrument display equipment to display.

[0027] The integral type extremely narrow frame instrument display screen is designed with installation foot structure and plastic clip fixed with whole vehicle, and appearance piece glass cover plate of narrow frame.

[0028] The die casting of the integral extremely narrow frame instrument display screen is designed as an appearance piece of the instrument display screen assembly, so that a rear shell can be saved, and the overall thickness can be made thinner; the die casting back plate of the integral extremely narrow frame instrument display screen is designed with a vehicle-mounted mounting foot structure.

[0029] The front of the integral extremely narrow frame instrument display screen is designed with a conventional explosion-proof film and a glass cover plate, wherein the glass cover plate and the liquid crystal glass are fixed by full lamination with OCA (optical transparent adhesive), so that the display effect is better and clearer.

[0030] The black edge part around the glass cover plate is fixed with the die casting back light by structure adhesive, so that the structure is more firm and the thickness is thinner.

[0031] The glass cover plate of the integral extremely narrow frame instrument display screen is directly fixed on the die casting back light, the outer edge of the glass is flush with the outer edge of the back light, the glass cover plate edge structure is cancelled, and the frame looks narrower.

[0032] The structure of the integral extremely narrow frame instrument display screen is simpler and saves material quantity, and the main advantage is that the frame of the display screen is narrower, the thickness is thinner, and the quality is lighter.

[0033] The glass cover plate is used as a front appearance piece of a display area, the glass cover plate and the die casting back light are fixed by structure adhesive, and the glass cover plate and the liquid crystal glass are full-laminated by OCA (optical transparent adhesive).

[0034] The die casting back light is used as a back appearance piece of the instrument display screen, and the die casting back light is fixed by structure adhesive before the glass cover plate, so that the structure is made thinner.

[0035] The narrow frame structure is that the glass cover plate has the same outer dimension as the die casting back light, and the design without a rear shell edge saves the width of the edge material and the matching gap, the overall frame of the display screen assembly is narrowed, and the extremely narrow frame design is realized.

[0036] In summary, the narrow frame width of the instrument assembly can be designed to be the same size as the outer edge of the die casting rear shell, the edge design is removed, the frame width of the instrument assembly can be reduced, the retaining wall and the gap are removed, the cover glass is directly fixed on the bearing surface of the die casting back light, and the structure adhesive (fourth point adhesive) is used for pasting and fixing between the cover plate and the die casting.

[0037] The black frame size of the instrument assembly can be made narrower, and the visual effect is better. The Z direction can also save space, the thickness is thinned, and the thickness of the structural adhesive can be 0.15 mm, the thickness of the conventional VHB adhesive is 0.64 mm, and the overall thickness is thinned. The structure realizes that the black frame of the instrument display screen is narrower, the glue curing connection width can be designed to be extremely small, the width of the frame around the non-display area of the display device is minimized, the design requirements of the extremely narrow frame instrument display screen structure are met, the production process is simplified, and cost reduction is realized. The bracket, the PCBA and the plastic plug cover are fixed by screws, and are fixed on the back of the die-casting backlight.

[0038] The narrow frame of the utility model benefits from the narrow frame of the backlight, the narrow edge of the glass cover plate and the structural adhesive used for pasting and fixing between the two; the glue pasting width is narrower, and the pasting is more firm; the frame of the instrument display screen assembly is narrower, and the thickness is thinner. The integrated extremely narrow frame instrument display screen is designed as an observation piece of the automobile display device.

[0039] Reference Figure 3 and Figure 4 The main assembly steps are that the glass cover plate and the liquid crystal glass are directly pasted, and the glass cover plate and the die-casting backlight are directly glued and pasted and fixed, which is the key to guarantee the narrow frame.
