Description
[technical field]
The utility model relates to a kind of light guide plate, light emitting module, light guide module and LCD.
[background technology]
Liquid crystal indicator is a kind of PASSIVE OPTICAL formula display device, it shows mainly passing through or the obstructed realization of coming by control light beam that external light source sends, therefore need corresponding backlight or front optical module, this backlight or front optical module can be realized Presentation Function with the beam direction liquid crystal panel that external light source sent.
This backlight or front optical module need be used the light that the light-guide plate guides light source sends, and makes it enter liquid crystal panel in the uniform area light source mode and realizes Presentation Function.For realizing the lightening of backlight or front optical module, light guide plate employing transparent material such as acryl resin, polycarbonate, polyvinyl resin etc. in it, but, these materials still can not satisfy the more frivolous requirement of light guide plate, and use for a long time and can produce aetiolation owing to the ultraviolet light irradiation of fluorescent lamp in backlight or the front optical module, influence its optical property.For realizing the more frivolous requirement of light guide plate, a kind of light guide plate material appears recently: polyolefin resin (Cycloolefin Polymer), this material can make light guide plate weight lighter, but it is owing to the aetiolation that the ultraviolet light irradiation of fluorescent lamp in backlight or the front optical module produces is more serious.
A kind of light guide plate of polyolefin material that adopts is exposed in U.S. Patent application the 10/109th, No. 676, and its open day is on October 3rd, 2002.See also Fig. 1, it is the sectional view of this patented claim LCD MODULE, this LCD MODULE comprises a liquid crystal panel 610, one backlight module (not indicating), an one die casting support 800 and a shell 900, this liquid crystal panel 610 comprises a thin film transistor base plate 612, colored filter 614 and liquid crystal therebetween (figure does not show), these thin film transistor base plate 612 outsides are provided with a printed circuit board (PCB) 612a, also be coated with one deck ITO (Indium Tin Oxide on this colored filter 614, tin indium oxide) electrode 614a cooperates thin film transistor base plate 612 to drive liquid crystal in this liquid crystal panel 610 with control whether passing through from the light of this backlight module.This backlight module comprises a light guide plate 720, a reflecting plate 740, some optical thin films 730 and a light source module (not indicating).This light guide plate 720 is made with polyolefin material.This light source module comprises that a fluorescent lamp 710, a light source cover 712 and are positioned at the uvioresistant film 712a on the light source cover 712.
Please consult Fig. 2 together, these fluorescent lamp 710 fluorescent tubes, 701 inwalls and shell are coated with uvioresistant film 703 and 703a respectively, and uvioresistant film 703 inwalls on fluorescent tube 701 inwalls also are provided with phosphor body 705.Uvioresistant film 703,703a and 712a on these fluorescent tube 701 inwalls, shell and the light source cover 712 can effectively stop harmful ultraviolet light of launching from fluorescent lamp 710, prevent to make light guide plate 720 to produce aetiolation.
Seeing also Fig. 3, is the sectional view of this another embodiment of patented claim LCD MODULE.For preventing that light guide plate 720 from producing yellow uvioresistant film 703 and 712a are plated in respectively on light guide plate 720 light entrance faces and the light source cover 712.
Seeing also Fig. 4, is the sectional view of this another embodiment of patented claim backlight module, and wherein light 717a is that light source sends and contains ultraviolet light, and light 719a is the light of this light outgoing after light guide plate 720.For preventing that light guide plate 720 from producing yellows, and uvioresistant material 703b is distributed in light guide plate 720 the insides.
This patented claim LCD MODULE adopts the less polyolefin resin of density as light guide plate 720 materials, can alleviate the backlight module of this light guide plate 720 of employing and the weight of LCD, shortcoming at the type light guide plate 720 easy yellow under fluorescent lamp 710 irradiations, on fluorescent lamp 710 fluorescent tubes, 701 inwalls and shell and light source cover 712, be coated with uvioresistant film 703,703a and 712a respectively respectively, prevent to make light guide plate 720 produce yellow because of the irradiation of fluorescent lamp 710.
But, outside the light that deblooming lamp 710 sends, because light path reciprocity, the light in the LCD external world also can enter the backlight module of the inside from liquid crystal panel 610, and, light guide plate also may be subjected to the irradiation of extraneous ultraviolet light in manufacturing, transportation and use, so the light guide plate 720 in the backlight module also may produce yellow, particularly be applied to the preceding photosystem of reflection-type or semi-reflection-type LCD, light guide plate in it is positioned at the outside surface of this LCD, is subjected to extraneous ultraviolet irradiation and flavescence easilier.Plating uvioresistant film 703,703a and the 712a technology on fluorescent lamp 710 fluorescent tubes, 701 inwalls and shell and light source cover 712 that U.S. Patent application is provided for the 10/109th, No. 676 can not prevent the irradiation of extraneous ultraviolet light and make light guide plate 720 generation yellows.
If distribution uvioresistant material in light guide plate 720, then must in light guide plate 720, distribute and at fluorescent lamp 710 fluorescent tubes, 701 inwalls and shell, uvioresistant material 703b with the same density of uvioresistant film of plating on the light source cover 712, just can effectively stop extraneous ultraviolet light irradiation, but because the light guide plate volume is relatively large, so adopt the method will use a large amount of uvioresistant material 703b, cost is very high, if the uvioresistant material 703b density deficiency that in light guide plate 720, distributes, to make surface that light guide plate 720 and extraneous ultraviolet ray contacts ultravioletly shine more the ratio and be easier to yellow because of being subjected to, and the processing procedure of distribution uvioresistant material 703b is also more loaded down with trivial details in light guide plate 720, makes cost increase.
