Abstract
The utility model discloses a kind of light guide plate and adhesive tape structure, including light guide plate (1), glue frame (2), the edge of the light guide plate (1) is provided with some rectangles projection (3) being spaced apart, and the groove formed between the projection (3) is LED (5) holding tank (4).The utility model reduces order of reflection by changing the structure of light guide plate, increases light utilization efficiency, improves backlight illumination, and the utility model process is simple is practical, cost free change, improves brightness and also in a disguised form reduces production cost simultaneously.
Description
Technical field
The utility model belongs to liquid panel technique field, and in particular to a kind of light guide plate and adhesive tape structure.
Background technology
Liquid panel technique development is maked rapid progress, and specification is constantly lifted, and matched module requirement is also continuous
Lifting.The main flow resolution ratio of current liquid crystal panel has reached FHD ranks, 4K, 2K product are also shown up prominently, and resolution ratio is carried
Rising causes the decline of penetrance, and requirements at the higher level are proposed to backlight illumination.The means for improving backlight illumination have a lot, such as improve
LED luminance, improves light guide plate mesh point minute surface degree etc..
Glue frame is usually white or black in the prior art, and as shown in Figures 4 and 5, after LED is lighted, most of light is from light extraction
Face enters light guide plate, is partly introduced into the light of light guide plate in LED grooves by after multiple reflections, some entrance light guide plates have
Absorbed by the glue-line that flexible circuit board or flexible circuit board adhere to, some losses cause light source wave in air propagation path
Take, also in a disguised form increased production cost.
Utility model content
Utility model purpose：The structure of a kind of light guide plate and adhesive tape is provided, changes current conventional light guiding plate and glue frame
Collocation mode, LED is not directly entered the light of guide-lighting plate part and faster enter light guide plate, reduce the damage that multiple reflections bring
Consumption.
Technical scheme：
A kind of light guide plate and adhesive tape structure, including light guide plate, glue frame, the edge of the light guide plate are provided with some being spaced apart
Rectangle it is raised, the groove formed between the projection is LED holding tanks.LED is inserted in LED holding tanks, LED is sent
The light for not being directly entered guide-lighting plate part faster enter light guide plate, reduce the loss that brings of multiple reflections.
Preferably, the raised material of the rectangle is light guide plate.
Preferably, the light guide plate is formed in one with rectangle projection.
Preferably, the distance between LED light-emitting areas and light guide plate incidence surface are 0~0.3mm, preferably 0~0.1mm.
Preferably, LED is 0~1mm with convex side back gauge.
Preferably, the raised and light guide plate main body junction is rounding or corner cut, rounding or corner cut are conducive to
LED light enters light guide plate.
Preferably, the radius of the rounding is 0~1mm, preferably 0~0.5.
Preferably, the corner cut O is 0~1mm.
Beneficial effect：
By design of the present utility model, order of reflection is reduced, increase light utilization efficiency, improve backlight illumination, this practicality
Novel process is simple, practical, cost free change, improves brightness and also in a disguised form reduces production cost simultaneously.

Specific embodiment
According to following embodiments, the utility model may be better understood.However, those skilled in the art easily manages
Solution, the content described by embodiment is merely to illustrate the utility model, without should also without limitation on institute in claims in detail
The utility model of thin description.
As shown in figure 1,1 is light guide plate, 2 is glue frame, and 3 is projection, and 4 is LED holding tanks, and 5 is LED.
As depicted in figs. 1 and 2, a kind of light guide plate and adhesive tape structure, including light guide plate, glue frame, the edge of the light guide plate
Some rectangles projections being spaced apart are provided with, the groove formed between the projection is LED holding tanks.The rectangle is raised
Material be light guide plate, the light guide plate is formed in one with rectangle projection.LED light-emitting areas and light guide plate incidence surface it
Between be 0~0.3mm apart from H, preferably 0~0.1mm, LED and convex side back gauge W are 0~1mm.
The raised and light guide plate main body junction is rounding or corner cut, and rounding or corner cut are conducive to LED light to enter
Light guide plate, the radius R of the rounding is 0~1mm, preferably 0~0.5, the corner cut O is 0~1mm.
As shown in figure 3, LED is inserted in LED holding tanks, make the light for not being directly entered guide-lighting plate part that LED sends more
Enter light guide plate soon, reduce the loss that multiple reflections bring, be put into the LED holding tanks that light guide plate is surrounded by by LED, reduce
Order of reflection, increases light utilization efficiency, improves backlight illumination.
