Abstract

The invention relates to a lateral type light-emitting diode (LED) backlight module with a glass light guide plate. The LED backlight module comprises a backlight device outer frame (7), and a diffusion plate (2), a brightening plate (3), a light guide plate (4) and a reflecting plate (6) which are sequentially arranged in the backlight device outer frame (7). The LED backlight module is characterized in that LED light strips (5) are respectively arranged on two sides of the light guide plate (4) which is made of a glass plate. According to LED backlight module, a new backlight module scheme is provided, and a light guide plate which is made of common acryl materials is replaced by the glass light guide plate. Compared with the light guide plate made of the acryl materials, the glass light guide plate has the advantages that the glass is low in cost, high in high-temperature resistant property, and is easy to form at one time; and therefore, the backlight effect with high performance can be achieved in a low-cost mode.

Description

A kind of glass LGP side entering type LED-backlit module
Technical field
The present invention relates to a kind of glass LGP side entering type LED-backlit module.
Background technology
Present stage, liquid crystal indicator has been widely used in the individual consumer's goods such as notebook computer, computer monitor, TV because in light weight, advantages such as volume is little, little power consumption, radiation is low, quality is good are arranged.Because LCD panel itself does not have the characteristics of luminescence, therefore must on the LCD panel, add a light emitting source, can reach display effect, backlight source module promptly provides the optical module of LCD display back light.The LCD backlight source module can use light emitting diode (LED), cold-cathode fluorescence lamp (CCFL), external electrode fluorescent lamp (EFFL) etc. as light source.
Along with development of semiconductor, the particularly appearance of high-power LED chip, LED brightness and efficient have had significant raising, make that the increasing LCD of being applied in LED-backlit source is backlight.Utilizing led light source is that panel backlight has a lot of advantages as LCD panel backlight than using common CCFL.Wherein the most significantly improving is the expansion of colour gamut.Use LED-backlit to have broader colour gamut, realize more gorgeous color.But also can realize dynamically controlling the RGB mixed light, and between 9600K and 6500K, adjust white balance, and can sacrificing luminance and contrast.
The LED-backlit implementation method in design and manufacturing process, is different from CCFL implementation method backlight fully at present, mainly contains two kinds of side-light type and straight-down negatives at present.The side-light type scheme adopts side emitting, utilizes blooming piece such as LGP that light is turned to, on the LCD panel in guiding dead ahead.
Summary of the invention
The purpose of this invention is to provide a kind of glass LGP side entering type LED-backlit module, can under lower cost, realize the effect backlight of superior performance.
A kind of glass LGP side entering type LED-backlit module; Comprise the back lighting device housing; And be installed in diffuser plate, blast plate, LGP and the reflector in the back lighting device housing successively; Its special feature is: be separately installed with LED lamp bar in the LGP both sides, and LGP adopts glass plate.
Wherein two sides processes near LED lamp bar are polished and side light-conductive rate>90% on the glass plate.
Wherein the one side near liquid crystal panel is handled through atomizing on the glass plate.
Wherein the one side away from liquid crystal panel is provided with reflective spot on the glass plate, and this reflective spot is circle, triangle, square or polygonal shape, and the distribution density of reflective spot is that both sides are sparse, the centre is intensive, the reflecting rate of this face reflective spot>30%.
The photoconductivity of glass plate>90% wherein.
The invention provides a kind of new module scheme backlight, adopt the glass LGP to substitute common acrylic material LGP.Compare acrylic, glass cost is lower and have high-temperature stability preferably, is easy to one-shot forming, therefore can under lower cost, realize the effect backlight of superior performance.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is the structural representation of glass plate among the present invention.
The specific embodiment
Embodiment 1:
As shown in Figure 1; A kind of glass LGP side entering type LED-backlit module; Comprise back lighting device housing 7; And be installed in diffuser plate 2, blast plate 3, LGP 4 and the reflector 6 in the back lighting device housing 7 successively, be separately installed with LED lamp bar 5 in LGP 4 both sides, and LGP 4 adopts the glass plate of glass light conductivity>90%.
As shown in Figure 2, two sides, 43 processes near LED lamp bar 5 on the glass plate are polished, thereby increase the transmitance of LED light, require side 43 light-conductive rates>90% after the polishing.And the one side (upper surface 41 among Fig. 2) near liquid crystal panel 1 is handled through atomizing on the glass plate, makes that the light of glass plate output is more even.
One side (lower surface 42 among Fig. 2) away from liquid crystal panel 1 is provided with a lot of reflective spots on glass plate in addition; This reflective spot is circle, triangle, square or polygonal shape; And the distribution density of reflective spot is that (on glass plate) both sides are sparse, the centre is intensive, and makes reflecting rate>30% of this face reflective spot.
