Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments, but the present invention is not limited to this embodiment, and the protection scope of the present invention should be included in all similar structures and similar variations thereof. The utility model provides an upper and lower, preceding, back, left and right equidirectional use only for the description convenience, it is not right the technical scheme's of the utility model restriction.

As shown in fig. 2-6, the utility model discloses a modified vehicle-mounted display screen, including panel frame 1, be provided with the ascending cavity of opening in the panel frame 1, from last one-level step 19 that has set gradually under to on the lateral wall of cavity, second grade step 20 and tertiary step 21, be provided with glass apron 13 through glue on the one-level step 19, be provided with LCD screen 15 through frame 11 and cushion 12 on the second grade step 20, be provided with backlight unit on the tertiary step 21, be provided with recess 2 in the lateral wall of second grade step 20, be provided with lamp strip 4 in the recess 2, be provided with a plurality of LED lamp 5 along its length direction interval on lamp strip 4.

Furthermore, a notch 3 is formed in the third-stage step 21, a through hole is formed in the side wall of the cavity of the panel frame in the notch, and the circuit connecting assembly of the lamp strip 4 penetrates through the notch 3 and the through hole.

Further, the backlight module comprises a reflecting film 6, a light guide plate 7, a diffusion film 8, a brightness enhancement film 9 and a polarizer 10 which are arranged in sequence.

Furthermore, the glass cover plate 13 is bonded with the liquid crystal screen 15 through an optical adhesive 14.

Further, the cushion pad 12 is made of foam.

Further, the glue is double-sided glue or structural glue 16.

Specifically, the panel frame 1, the liquid crystal panel 15, the backlight module, the buffer pad 12, the frame 11, the light bar 4, the LED lamp 5, the reflective film 6, the light guide plate 7, the diffusion film 8, the brightness enhancement film 9, the polarizer 10, the optical adhesive 14, the structural adhesive 16, and the like in this embodiment all adopt known schemes in the prior art, and those skilled in the art know the schemes, and are not described herein again.

The working principle of the embodiment is as follows:

as shown in fig. 2, which is a cross-sectional view of the whole display screen at the narrow frame, the black frame of the display screen refers to the display edge 17 of the display screen to the outer edge 18 of the glass cover plate, and the width of the black edge includes the horizontal distance from the display edge 17 of the display screen to the cushion pad 12, the width of the double-sided adhesive or structural adhesive 16, and the tolerance of the two sides thereof. The utility model discloses a display screen's display limit 17 is the same with prior art to the horizontal distance of blotter 12, the width of double faced adhesive tape or structural adhesive 16 and both sides tolerance, the black limit of this part, the difference is the width of blotter 12. The utility model discloses a panel frame 1 is a display screen panel frame with support in a poor light and display screen shell collection in an organic whole, set up recess 2 in display screen panel frame 1, 4 subsides of lamp strip in the backlight unit of display screen now are adorned in recess 2, consequently, the backlight support among the backlight unit has been saved, the width of blotter 12 of the 15 downside of LCD screen has been reduced, thereby the black margin of display screen both sides has been reduced, and the thickness of display screen has also been attenuate, let the equipment sense of wholeness more frivolous, reduce the influence of black margin region to display area display effect, reduce the constraint of frame to the screen, let screen itself more outstanding, it is bigger to give a user's screen display area, the field of vision is broader sense, let screen vision impact force, improve user's impression experience, the cost of display screen is reduced.

Fig. 3 is a schematic diagram of a semi-finished product without fixing the liquid crystal panel 15 and the glass cover plate 13, after the light bar 4 is attached in the groove 2 of the panel frame 1, the reflective film 6, the light guide plate 7, the diffusion sheet 8, the brightness enhancement film 9 and the polarizer 10 are sequentially attached on the third-stage step 21 of the panel frame 1, and finally the frame 11 and the buffer pad 12 are sequentially attached on the panel frame 1 and the polarizer 10.

As shown in fig. 4, the panel frame 1 integrates a backlight support and a display screen shell, and is a main framework of the whole display screen, and the panel frame plays a role in supporting a backlight module and supporting a glass cover plate 13 and a liquid crystal screen 15, so that the backlight support required in the backlight module is omitted, a first-stage step 19 is used for supporting the glass cover plate 13, a second-stage step 20 is used for supporting the liquid crystal screen 15, a third-stage step 21 is used for supporting the backlight module, a notch 3 is used for avoiding a light bar 4 to connect with a main circuit board, and a groove 2 is used for mounting the light bar 4. Because panel frame 1 is for encircleing the structure, recess 2 can' T directly be through the mould shaping, and accessible T type sword once only machine tooling shaping comes out.

As shown in fig. 5, lamp strip 4 is made by FPC, pastes a plurality of LED lamp 5 according to the leaded light demand on the lamp strip, and the lamp strip is not only thin but also soft, and structural space can be saved to thin lamp strip, and soft lamp strip can adapt to different structure subsides dress faces.

As shown in fig. 6, the liquid crystal panel 15 is attached to the glass cover 13 by the optical adhesive 14, and is fixed to the panel frame 1 by the double-sided adhesive or the structural adhesive 16 after forming a module.
