Abstract

The utility model discloses a Liquid Crystal Display (LED), comprising a LED panel and a backlight, the LED panel is fixed to the side that the backlights has light out, also the utility model comprises a metal frame covering around the LED panel and the back light. The utility model also discloses a backlight comprising a light source, a light guide plate for translate the light emitted from the light source to surface light source, and a optical film on the side that the light is emitted out of the light guide plate. The utility model uses a metal frame to replace the plastic frame, which reduces the bulk of the whole model set, and because of the electric conductivity of the metal frame, the static-free ability of the model set is improved.

Description

A kind of LCD and backlight

[technical field]

The utility model relates to a kind of LCD, particularly a kind of LCD and backlight that is applied in the mobile phone.

[background technology]

Because panel of LCD itself is not had a characteristics of luminescence, therefore, must add a light emitting source on panel of LCD, can reach display effect.Backlight is the optical module that a back side light source is provided for panel of LCD, and it is a key part and component of LCD operate as normal, has the brightness height, long, luminous characteristics such as evenly of life-span.At present, the major product kind of backlight has: light emitting diode (LED), halogen tungsten lamp, electroluminescence (EL), cold-cathode fluorescence lamp (CCFL), emission of cathode lamp (CLL) and metal halide lamp etc.Backlight mainly is made up of light source, light guide plate, optical film sheet, plastic cement frame etc., and as depicted in figs. 1 and 2, the guard space 5 between common glue frame 4 backlight and the face glass (LCD) 3 is 0.1mm.

At present, the backlight of a lot of mobile phones is the structural designs that adopt glue frame and light guide plate, and relies on the intensity of glue frame to protect panel of LCD.The size of the size ratio panels glass of actual LCD is about the big 1.4mm of length and width direction.And according to the requirement of product miniaturization, the size of LCD is the smaller the better.And backlight source module is under the situation that does not increase conductive material, and mobile phone is also poor to the antistatic effect aspect.

[summary of the invention]

The utility model is exactly in order to overcome above deficiency, to have proposed the LCD that a kind of framework is thin, antistatic effect is strong.

For achieving the above object, the utility model proposes a kind of LCD, comprise panel of LCD and backlight, described panel of LCD is fixed on backlight and has the one side that light penetrates, and comprises that also frame is enclosed within the metal framework of the surrounding of panel of LCD and backlight.

The xsect of described metal framework is preferably " L " type.

Described metal framework is preferably thin chase.

Further comprise the flexible protective layer that is clipped between metal framework and the panel of LCD.

Wherein, described flexible protective layer can be foam.

For achieving the above object, the utility model also proposes a kind of backlight, comprise light source, be used for changing the light that light source sends the light guide plate of area source into and be positioned at the blooming piece of the irradiant one side of light guide plate, comprise that also frame is enclosed within the metal framework around the light guide plate plane.

Described metal framework is thin chase.

The beneficial effects of the utility model are:

The utility model has used metal frame to replace the glue frame, and metal frame can be accomplished very thin, has dwindled the volume of entire module; And, improved the anti-static ability of module because metal frame has electric conductivity.

Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.

Fig. 5 (a), Fig. 5 (b) are overall diagram, and Fig. 5 (c), Fig. 5 (d) are partial enlarged drawings.

[embodiment]

The utility model discloses a kind of LCD,, comprise metal frame 1 (for example chase), protectiveness foam 2 and display panels (LCD) 3 as Fig. 3 (a), Fig. 3 (b) and shown in Figure 4.The chase frame be enclosed within display panels 3 and backlight around, the xsect of metal framework is preferably " L " type, protectiveness foam 2 is filled in the slit between chase and the face glass 3, the protection chase can not squeeze cullet panel 3.The utility model backlight comprises the metal frame 1 among Fig. 5, light guide plate 7, light source and diffusion barrier material 8.

Also can replace chase, but relatively have superiority at chase on intensity and cost performance with other metal material frames; Protectiveness foam 2 also can adopt other soft protective seam to replace, such as the rubber-like plastic cement.

In the present embodiment, novel chase replaces the glue frame 4 in traditional backlight source fully in the LCD, and protectiveness foam 2 is filled in the effect of playing cover glass panel 3 in the slit.

The beneficial effect of the specific embodiments of this Novel LCD is:

The width of traditional backlight glue frame 4 is more than the 0.6mm; more than the 0.1mm of gap; integral width is exactly than the wide at least 0.6*2+0.1*2=1.4mm of face glass 3; and the module of Novel LCD replaces the position of glue frame 4 fully with novel chase and protectiveness foam 2; thickness is respectively novel chase 0.15*2mm, protectiveness foam 0.15*2mm, and thickness is 0.6mm altogether.Like this can be than the width more than the little 0.8mm in traditional backlight source.The utility model dwindles overall volume, enlarges the ratio of vision area and overall volume, meets the requirement of the big vision area of trend mobile phone small size of present requirement.And the utility model carries out the antistatic effect that conducting improves module by chase and casing.

The backlight that the utility model proposed; as shown in Figure 5; comprise that frame is enclosed within light guide plate plane metal frame 1, light source, light guide plate 7 and diffusion barrier material (blooming piece) 8 all around; light guide plate 7 is used for changing the light that light source sends into area source; be about to pointolite or line source and change area source into by processing; blooming piece is positioned at the irradiant one side of light guide plate, further light is handled, and metal frame 1 is used for fixing and protects light source, light guide plate 7 and diffusion barrier material (blooming piece) 8.The xsect of metal frame 1 is preferably " L " type, can be thin chase.

Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design; can also make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of being submitted to.
