Description
Technical field
The utility model relates to backlight source domain more particularly to a kind of U-shaped light guide plate leaded light uniformity structures of improvement.
Background technique
As smart phone is constantly innovated, technically continuous to break through, Qi Liuhai (U-shaped) mobile phone has become entire intelligence
It can the mobile phone market mainstream.It is bigger that the design of neat fringe can allow mobile phone to provide in the case where not increasing volume, not influencing feel
Screen accounting.According to incompletely statistics, at present other than iPhone X, the famous brand names such as 20 cell phone manufacturers has been had more than and have been adopted
With the design of " bang screen ", Liu Haiping has become the wind vane of general marketplace.In thin film transistor liquid crystal display technology (TFT-
LCD:Thin Film Transistor Liquid Crystal Display) liquid crystal display die set field, Qi Liuhai (U-shaped)
Backlight is indispensable luminous component, and effect brightness unevenness at U-type groove, display effect difference has been the skill of U-shaped backlight guide plate processing
Art problem.
Utility model content
(1) the technical issues of solving
The utility model provides a kind of U-shaped light guide plate leaded light uniformity structure of improvement, improves the display of U-shaped light guide plate
Uniformity improves the light guide effect of U-shaped light guide plate.
(2) technical solution
The utility model is achieved by the following technical programs: a kind improves U-shaped light guide plate leaded light uniformity structure,
Including a U-shaped light guide plate, there are the first site and the second site in the U-shaped end of the U-shaped light guide plate, and second site is U-shaped two
End side tail portion；The light-emitting surface of the U-shaped light guide plate is equipped with V-cut, and the V-cut includes: the first area V-cut and the 2nd V-cut
Area, close to the U-shaped end of U-shaped light guide plate (5), the first area V-cut (4) is U-shaped far from U-shaped light guide plate (5) in the 2nd area V-cut (3)
End.
Further, second site adjusts site density degree according to practical illumination effect, makes the density of the second site
Lower than the density of the first site.
Further, region area of the region area of second site less than the first site, the site ruler of the second site
The very little dot size for being greater than the first site.
Further, the 2nd area V-cut adjusts the depth of V-cut according to practical illumination effect, makes to lead with condition of equivalent thickness
The V-cut of tabula rasa calculates depth and compares, and the depth in the 2nd area V-cut reduces 1-5 μm, and the depth in the first area V-cut arrives
The depth in the 2nd area V-cut is by increase.
Further, the both ends rounded edges structure at the U-shaped place of U-shaped light guide plate is micro- laciniation.
(3) beneficial effect
The utility model provides a kind of U-shaped light guide plate leaded light uniformity structure of improvement, has following the utility model has the advantages that light guide plate
U-shaped side tail portion dot density reduces, and improves the refraction of light ray energy, improves uniformity；The U-shaped two ear V-CUT of side of light guide plate is done
Shallowly, improve reflection light at the top of the angle R, improve uniformity；Sawtooth micro-structure is done in side at light guide plate fillet, and it is anti-to destroy mirror surface
The conditioned reflex penetrated makes tail portion glue frame wall reflect light and disperses as far as possible.
