Problems solved by technology

When using the second method, due to the flatness of the display backlight itself, that is, the problem of its own unevenness, when it is glued to the LCD display, the LCD display will be stressed; at the same time, the display backlight itself also has weight. , this gravitational force is also applied directly to the LCD
Due to its own characteristics, the liquid crystal display will suffer from MURA failure, that is, the uneven brightness of the display will cause various traces.
At the same time, due to the characteristics of plastic injection molding cost, the cover plate will have injection stress problems, so that the cover plate will have rainbow patterns in the display window, which directly affects the display effect of the display screen

Embodiment 1

[0023] A backlight assembly structure of a vehicle-mounted display of the present invention, such as figure 1 As shown: it includes a cover structure 1, a display screen 2 and a display backlight 3. A groove 31 matching the display screen 2 is arranged in the display screen backlight 3, and the display screen 2 is installed in the groove 31 and connected with the groove 31 is provided with a gap, the upper surface of the display screen 2 is closely and fully bonded to the lower surface of the cover structure 1 through the first adhesive layer 4, and the upper surface of the groove frame 32 of the groove 31 of the display screen backlight 3 passes through the first adhesive layer 4. The second adhesive layer 5 is in close contact with the lower surface of the cover plate structure 1 .

[0024] Wherein, the first adhesive layer 4 is an OCA optical adhesive layer, and the thickness range of the OCA optical adhesive layer is 0.5-0.1 mm; the second adhesive layer 5 is an OCA optica...

Embodiment 2

[0028] The difference between this embodiment and Embodiment 1 lies in the cover plate structure 1 .

[0029] In this embodiment, the cover plate structure 1 is as figure 2 Shown:

[0030] The cover plate structure 1 includes a cover plate 11 and a transparent panel 12, the transparent panel 12 is set in the cover plate 11, the transparent panel 12 corresponds to the window of the display screen 2; a diaphragm is pasted on the upper surface of the cover plate 11 13; the diaphragm 13 is a FILM diaphragm. Wherein, the thickness of the transparent panel 12 is the same as that of the cover plate 11, and the transparent panel 12 includes a PC plate and a PMMA plate; the cover plate 11 is an IML cover plate, and the transparent panel 12 is set in the cover plate 11, that is, the transparent panel 12 is injected into the IML. in the cover.

[0031] In this embodiment, a transparent panel 12 corresponding to the window of the display screen 2 is placed in the cover plate 11. Since...

Abstract

The invention relates to a backlight assembling structure of a vehicle-mounted display screen. The backlight assembling structure comprises a cover plate structure, a display screen and a display screen backlight; a groove which is matched with the display screen is arranged in the display screen backlight; the display screen is mounted in the groove and a gap is formed between the display screenand the groove; the upper surface of the display screen tightly and completely fits with the lower surface of the cover plate structure through a first glue layer; and the upper surface of a groove frame of the groove of the display screen backlight tightly fits with the lower surface of the cover plate structure through a second glue layer. Through arranging the display screen in the display screen backlight, completely fitting the display screen with the cover plate and fitting the display screen backlight with the cover plate, the display screen backlight and the display screen are divorcedfrom an assembling relationship, so that the weight and flatness problems of the display screen backlight are avoided, the display screen is prevented from stress and the MURA problem of the displayscreen is solved; and through arranging a transparent panel corresponding to a display screen window in the cover plate, the newton stripe problem in the display screen window is solved.

Description

technical field [0001] The invention relates to the field of vehicle display technology, in particular to a backlight assembly structure of a vehicle display. Background technique [0002] A general car display screen consists of a display screen and a backlight. When the full lamination method is used, two methods will be used. The first is the full lamination of the display module and the COVER LENS, that is, the LCD display and backlight assembly are fully bonded to the glass cover or composite sheet cover , the second is the LCD screen and COVER LENS, the backlight of the screen is bonded to the LCD screen through double-sided adhesive. When using the second method, due to the flatness of the display backlight itself, that is, the problem of its own unevenness, when it is glued to the LCD display, the LCD display will be stressed; at the same time, the display backlight itself also has weight. , this gravitational force is also applied directly to the LCD screen. Due ...
