Abstract

The invention discloses an LCD display device with a black plastic rubber. The LCD display device with the black plastic rubber comprises an LCD screen which is formed by overlapping an upper piece of glass and a lower piece of glass; an upper polarizing plate is overlapped above the upper piece of glass, and while a lower polarizing plate is overlapped below the lower piece of glass; an optical film is arranged below the lower polarizing plate, comprising an upper bright enhancement film, a lower bright enhancement film and a diffusion film which are arranged from top to bottom in a sequence; the lower polarizing plate is connected to be above the upper bright enhancement film through black white tape; a light guide plate is connected to be below the diffusion film; the black plastic rubber is arranged at the circumferential side of the structure above and overlapped with the black white tape; a reflecting film is arranged below the light guide plate and the black plastic rubber; iron frames are arranged below the reflecting film and at the circumferential side of the black plastic frame. According to the device, the white plastic frame is replaced by the black plastic frame; light reflected beside the black plastic frame and between the black white tapes can be absorbed by the black plastic frame, so that the problem of light leaking can be solved.

Description

A kind of LCD display device of black glue frame
Technical field
The present invention relates to technical field of liquid crystal display, particularly a kind of LCD display device adopting black glue frame.
Background technology
As shown in Figure 1, the structure of current LCD display device comprises the upper polaroid 1, upper glass 2, lower-glass 3, lower polaroid 4, black and white glue 5, upper bright enhancement film 6, lower bright enhancement film 7, diffusion barrier 8 and the light guide plate 9 that stack gradually, surrounding adularescent glue frame 11, have reflectance coating 10 below light guide plate 9 and white size frame 11, the below of reflectance coating 10 and the surrounding of white size frame 11 have chase 12.Along with the development of the narrow frame technology of LCD, a lot of product is because A.A district is more and more less to the space at the backlight inner groove edge of assembling LCD, namely for the LCD product of narrow frame, the size L playing interception part that in Fig. 1, white size frame 11 is overlapping with black and white glue 5 can reduce.As shown in Figure 2, black and white glue 5 shading-area can not play good shaded effect after reducing, and causes the leakage problem of whole liquid crystal display module to be difficult to solve.
Summary of the invention
For the above-mentioned weak point existing for existing LCD display device, applicant, through Improvement, now provides a kind of LCD display device of black glue frame, under the prerequisite not affecting finished product requirement brightness, solves leakage problem.
Technical scheme of the present invention is as follows:
A kind of LCD display device of black glue frame, comprise the LCD screen built up by upper glass and lower-glass, the top of described upper glass is folded upper polaroid, the below of described lower-glass is folded lower polaroid, blooming is had below lower polaroid, blooming is made up of upper bright enhancement film, lower bright enhancement film, diffusion barrier from top to bottom successively, connects lower polaroid, connect light guide plate below diffusion barrier above upper bright enhancement film by black and white glue; There is black glue frame all sides of said structure, and black glue frame and black and white glue partly overlap; There is reflectance coating the below of light guide plate and black glue frame, and there is chase the below of reflectance coating and all sides of black glue frame.
Advantageous Effects of the present invention is:
After white size frame is changed black glue frame by the present invention, the light reflexing to the space between black glue frame side and black and white glue is absorbed by black glue frame, thus solves leakage problem.
Advantage of the present invention provides in the description of embodiment part below, and part will become obvious from the following description, or be recognized by practice of the present invention.
Accompanying drawing explanation
Fig. 1 is the sectional view of the LCD display device of existing white size frame.
Fig. 2 is the light leak schematic diagram of the LCD display device of existing white size frame.
Fig. 3 is sectional view of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figure 3, the present invention includes the LCD screen built up by upper glass 2 and lower-glass 3, the top of upper glass 2 is folded upper polaroid 1, and the below of lower-glass 3 is folded lower polaroid 4, has blooming below lower polaroid 4.Blooming is made up of upper bright enhancement film 6, lower bright enhancement film 7, diffusion barrier 8 from top to bottom successively, connects lower polaroid 4, connect light guide plate 9 below diffusion barrier 8 above upper bright enhancement film 6 by black and white glue 5.There is black glue frame 11 ' all sides of said structure, and black glue frame 11 ' and black and white glue 5 partly overlap.There is reflectance coating 10 below of light guide plate 9 and black glue frame 11 ', and there is chase 12 below of reflectance coating 10 and all sides of black glue frame 11 '.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive without departing from the basic idea of the present invention or associate, all should think and be included within protection scope of the present invention.
