Description

The reflection configuration of direct type backlight module

Technical field

The utility model has the reflection configuration on multiple continuous inclined-plane relevant for a kind of reflection configuration of direct type backlight module, particularly reflecting surface.

Background technology

Backlight module is LCD (Liquid Crystal Display; LCD) one of fundamental parts.Because liquid crystal itself can be not luminous, must add backlight (major part is a fluorescent tube) at LCD panel (Panal) rear, the light penetration LCD panel (Panal) that backlight projects, the eyes that enter the people form image, and wherein the LCD panel comprises glass substrate (Mother Glass), liquid crystal, colored filter (ColorFilter), Polarizer associated materials such as (Polarizer) at least.That is to say, LCD must utilize backlight to project light source earlier, this light is earlier through first Polarizer and then through liquid crystal, and wherein liquid crystal molecule utilizes the variation of voltage to change the arrangement mode of liquid crystal molecule, and and then changes the light angle that penetrates liquid crystal.These light then also must be again through filter coating and second Polarizer of the colour in the place ahead.Because second Polarizer and first Polarizer angle differ 90 degree, originally should be able to be with all photoresistances every getting off, but because also have liquid crystal can control the angle of light between two Polarizers, therefore, can stimulate the magnitude of voltage of liquid crystal just can control the light intensity and the color of last appearance as long as change, and then the color combination of the different depths can on liquid crystal panel, occur.

Therefore, the performance quality of backlight module can directly have influence on the quality of LCD.The cost of backlight accounts for the about 3% to 5% of LCD module, and the electric power that is consumed more accounts for the about 75% of module, is considerable spare part in the LCD module.

The product used of large LCD was mainly mobile computer (Note Book PersonalComputer) and LCD monitor (LCD Monitor) in the past, and that the characteristic of the backlight module that requires mainly is is in light weight, volume is little, reach thin thickness.Therefore, when the backlight that exploitation LCD TV is used, enough video picture brightness (requiring more than the 450cd/m2 at least), broad visual angle (the sell goods specification can reach 170 ° at present), distinct image contrast's (about 500: 1 of the present LCD tv product watched must consideration can be arranged; About 1000: 1 of plasma-screen television product) and standardized serviceable life (at present product test value about 60,000 hours).Under above specification is considered, direct type backlight module just becomes the technology main flow of present collocation large LCD TV, the main concept of its design promptly is to can be in response to the demand of high brightness more, to be the side light source that can alleviate module weight and thickness consideration originally, by direct-light-type backlight light is broken up evenly, after making light change planar light source into, enter the technology mode of liquid crystal panel.

Please refer to Fig. 1, be the synoptic diagram of the spatial structure of the direct type backlight module of prior art.Reflection configuration with the direct type backlight module 100 of present 6 to 30 backlights 106 is an example, its internal reflection surface comprises at least by at least one side plate 110a, 110b, and the reflecting surface 102 vertical with backlight 106, the reflecting surface 104b parallel with backlight 106 and the reflecting surface 104a that is provided by base plate 112 for example are provided, and jointly the light of backlight 106 are broken up evenly.Backlight 106 cathode fluorescent tube (ColdCathode Fluorescent Lamp for example wherein; CCFL).

Above-mentioned and backlight 106 vertical side plate 110a are generally provided by the backlight holder, and the side plate 110b parallel with backlight 106 generally then provided by base plate 112, and base plate 112 is generally backboard.

Please refer to Fig. 2, be the sectional view of the backlight holder of prior art, generally speaking, the reflecting surface 102 vertical with backlight 106 provided by the backlight holder 111 of Fig. 2.Please refer to Fig. 3, be the sectional view of the backboard 113 of prior art, its dorsulum 113 also provides the reflecting surface 104b parallel with backlight except cremasteric reflex face 104a.Please refer to Fig. 4, for according to the direct type backlight module of Fig. 1 fragmentary cross-sectional view along profile line Y-Y ' gained, wherein the folded reflection angle θ x of reflecting surface 102 and level decides on the demand in the circuit space 108 of periphery, and for example reflection angle θ x can be between 105 ° to 115 °.Please refer to Fig. 5, the folded reflection angle θ y of the reflecting surface 104b of backboard 113 and level is between 125 ° to 135 °, as shown in Figure 5.

Please refer to Fig. 6, for according to the reflection configuration of the direct type backlight module of Fig. 1 fragmentary cross-sectional view when the reflection ray along profile line Y-Y ' gained.Generally speaking, by the light of the reflecting surface 104a of backboard 113 reflection backlight 106 through LCD panel 109 after, the part light 122 that reflects is injected non-light-emitting area, just can't effectively utilize the energy of part light 122.Please refer to Fig. 7 equally, for according to the reflection configuration of the direct type backlight module of Fig. 1 fragmentary cross-sectional view when the reflection ray along profile line X-X ' gained.By the light of the reflecting surface 104a of backboard 113 reflection backlight 106 through LCD panel 109 after, the part light 124 that reflects is injected non-light-emitting area, so can't effectively utilize the partly energy of light 124.

Letter, because in the reflection configuration of prior art, the reflecting surface on single inclined-plane only is provided, therefore behind the reflection backlight, effectively the part light at edge, luminous zone can be injected non-light-emitting area and cause damage, make that the edge of LCD screen is darker than central authorities, and cause the image quality at edge of LCD screen not good.
