Abstract
The utility model relates to an antifriction backlight, including last membrane of adding lustre to, membrane of adding lustre to down, the diffusion barrier, the light guide plate, reflector plate and adhesive tape frame, go up the membrane of adding lustre to, membrane of adding lustre to down, diffusion barrier, light guide plate and reflector plate from top to bottom establish in proper order in the adhesive tape frame, are equipped with the single face glue film on the reflector plate's plane of reflection, through setting up the single face glue film on the plane of reflection at the reflector plate, increase the interval of light guide plate and reflector plate, prevent that the foreign matter from rubbing between the two to the production of reducible white point effectively improves the yield.
Description
Technical Field
The utility model relates to a backlight technical field indicates an antifriction backlight especially.
Background
At present, a backlight source of a mobile phone generally adopts a plastic outer frame or a plastic and iron frame as an outer frame, a light shielding film is pasted on the outer frame, one side of the light shielding film is used for pasting and fixing an optical film material, the other side of the light shielding film is pasted with a liquid crystal display, a touch screen or a glass cover plate is pasted on the display screen, and the touch screen or the glass cover plate is pasted on the mobile phone shell. Because some fine burrs and foreign matters can not be completely removed by controlling the bright enhancement film, the diffusion film, the light guide plate, the rubber frame and other parts, particularly, the foreign matters between the reflecting sheet and the light guide plate are difficult to find in the luminescence inspection, white spots are easy to generate through friction in a falling and roller experiment, and the reject ratio is increased.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides an increase light guide plate and reflector plate's interval reduces the antifriction backlight that the white point produced.
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides an antifriction backlight, includes light intensifying film, diffusion barrier, light guide plate, reflector plate and glued iron frame down, upward light intensifying film, diffusion barrier, light guide plate and reflector plate establish in proper order in glued iron frame from top to bottom down, be equipped with the single face glue film on the reflector plate's reflecting surface.
Preferably, the thickness of the single-sided adhesive layer is 0.005-0.03 mm.
Preferably, a lamp strip is arranged on the light guide plate.
Preferably, a shading glue layer is arranged on the glue iron frame.
The beneficial effects of the utility model reside in that: the single-sided adhesive layer is arranged on the reflecting surface of the reflecting sheet, so that the distance between the light guide plate and the reflecting sheet is increased, and foreign matters are prevented from being rubbed between the light guide plate and the reflecting sheet, so that white spots can be reduced, and the yield is effectively improved.

Description of reference numerals: 1. a light-shielding adhesive layer; 2. an upper brightness enhancement film; 3. a lower brightness enhancement film; 4. a diffusion membrane; 5. a light guide plate; 6. a reflective sheet; 7. a rubber frame; 8. a light bar; 9. a single-side adhesive layer.
Detailed Description
Please refer to fig. 1-3, the utility model discloses an antifriction backlight, including last membrane 2 that adds lustre to, membrane 3 that adds lustre to down, diffusion barrier 4, light guide plate 5, reflector plate 6 and indisputable frame 7, last membrane 2 that adds lustre to, membrane 3 that adds lustre to down, diffusion barrier 4, light guide plate 5 and reflector plate 6 from top to bottom establish in indisputable frame 7 in proper order, be equipped with shading glue film 1 on the indisputable frame 7 of gluing, be equipped with lamp strip 8 on the light guide plate 5, be equipped with single face glue film 9 on the plane of reflection of reflector plate 6 (the face of laminating with light guide plate 5 promptly), the thickness of single face glue film 9 is 0.005-0.03mm, has increased the interval of light guide plate 5 and reflector plate 6, plays the friction between reduction reflector plate 6 and light guide plate 5, reduces the effect of white point to.
The above embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by the technical solution of the present invention by those skilled in the art are all within the scope of the present invention as defined by the claims.
