Description
Technical field
The invention relates to a kind of backlight module (Back Light Module) and LCD (Liquid Crystal Display, LCD), and particularly about a kind of backlight module of the area source that colorize can be provided and use the LCD of this backlight module.
Background technology
In order to cooperate modern life pattern, it is frivolous that the volume of video or image apparatus day by day is tending towards.Traditional cathode-ray tube (CRT) though still have its advantage, because the structure in internal electron chamber, makes that display is bulky and takes up space, and still has radiant rays to hinder problems such as eye when showing.Therefore, the plane formula display (Flat Panel Display) that cooperates photoelectric technology and semiconductor fabrication to be developed, for example LCD (LCD), organic light emitting display (OLED) or plasma display (Plasma Display Panel, PDP), become the main flow of display product gradually.
In sum, with regard to LCD, utilize kenel can slightly be divided into three kinds of reflective liquid-crystal display (reflective LCD), penetrating LCD (transmissiveLCD) and semi-penetrated semi-reflected liquid crystal displays according to its light source.With the penetration or the LCD of semi-penetration, semi-reflective is example, it is made of a liquid crystal panel and a backlight module, wherein, liquid crystal panel is made of the liquid crystal layer that two transparency carriers and are disposed between this two transparency carrier, and backlight module is in order to provide this liquid crystal panel required area source, so that LCD reaches the effect of demonstration.No matter it should be noted that it is reflective liquid-crystal display or penetrating LCD, a colored filter film (Color Filter) can be disposed usually on a transparency carrier of liquid crystal panel, so that LCD reaches the effect of full-color demonstration.
Fig. 1 is the structural representation of existing a kind of LCD.Please refer to shown in Figure 1ly, LCD 100 is a Thin Film Transistor-LCD (TFT-LCD), and it is made of a backlight module 110 and a liquid crystal panel 120.Backlight module 110 is disposed at the place, the back side of liquid crystal panel 120, and this back side is for the user, and backlight module 110 is made of a light guide plate 112, a line source 114 and a reflex housing 116.Wherein light guide plate 112 for example is a wedge shape light guide plate, and it has a light entrance face 112a, a smooth diffusingsurface 112b and a light-emitting face 112c.Reflex housing 116 is disposed at by the light entrance face 112a, and line source 114 then is disposed in the reflex housing 116.Above-mentioned line source 114 for example is one to be suitable for providing the cathode fluorescent tube (CCFL) or a light emitting diode array of white light.The light that line source 114 is provided can be incident in the light guide plate 112 by light entrance face 112a, and after the scattering and reflection through light diffusingsurface 112b, is passed to light-emitting face 112c outgoing.From as can be known above-mentioned, be the kenel of the area source of white by the light of light-emitting face 112c outgoing, in order to show required light source as liquid crystal panel 120.
Please continue to consult shown in Figure 1, liquid crystal panel 120 is made of a film transistor matrix substrate (TFT Array) 130, one colored optical filtering substrates 140 and a liquid crystal layer 150.Wherein, liquid crystal layer 150 is to be disposed between film transistor matrix substrate 130 and the colored optical filtering substrates 140.
As shown in Figure 1, dispose on the film transistor matrix substrate 130 a plurality of thin film transistor (TFT)s 132 (Thin Film Transistor, TFT) and a pixel electrode 134 (Pixel electrode) corresponding with each thin film transistor (TFT) 132.Thin film transistor (TFT) 132 is made of with drain electrode (Drain) 132d grid (Gate) 132a, channel layer (Channel) 132b, source electrode 132c (Source).Wherein, grid 132a is connected with one scan line (Scan line), keying in order to control channel layer 132b, source electrode 132c then is connected with a data line (Data line), when grid 132a is coupled to a suitable voltage, channel layer 132b promptly is the state of conducting, and the data that show about picture this moment just can be in regular turn writes in the pixel electrode 134 via data line, source electrode 132c, channel layer 132b, drain electrode 132d.In brief, just as the switch of each pixel, it can control the state of each pixel electrode 134 to thin film transistor (TFT) 132, and then reaches the effect of demonstration.
As shown in Figure 1, dispose one on the colored optical filtering substrates 140 and share electrode 146, and pass through thin film transistor (TFT) 132, reverse with the liquid crystal that drives between shared electrode layer 146 and the pixel electrode 134 as driven unit.In addition, dispose an alignment film (alignment layer) 148 and one alignment film 136 on above-mentioned shared electrode layer 146 and the pixel electrode 134 respectively, so that liquid crystal layer 150 is carried out orientation.
In addition, film transistor matrix substrate 130 is by a sealant (Sealant) 152 liquid crystal layer 150 to be disposed at therebetween with colored optical filtering substrates 140, and can in liquid crystal layer 150, add a plurality of separation materials (Spacer) 154, to keep the gap (Gap) between film transistor matrix substrate 130 and the colored optical filtering substrates 140.In addition, dispose polaroid (Polarizer) 160,170 on the outside surface of film transistor matrix substrate 130 and colored optical filtering substrates 140, so that LCD 100 reaches the effect of demonstration.
In sum, it should be noted that, because it is the kenel of white light that backlight module 110 is projected to the area source of liquid crystal panel 120, so need by the colored filter film 144 on the colored optical filtering substrates 140, the white light of backlight module 110 being filtered into the colorama (as: blue light, ruddiness or green glow) of various wavelength coverages, and make LCD 100 reach the effect of full-colorization.In other words, the utilization of colored optical filtering substrates is the major technique of present LCD development colorize.
Yet because colored filter film is comparatively loaded down with trivial details on making, and price is not cheap, causes the overall price of LCD can't be in further decline.In addition; because there are uneven phenomenon in colored filter film and the configuration regular meeting of black matrix on substrate on the substrate; so colored filter must cover one deck flatness layer (over coating) to reach the purpose of flattening surface on colored filter film and black matrix in manufacturing process; so will increase the complexity of colored filter on making, and also be a kind of burden on cost.In addition, because present most LCD all adopts colored optical filtering substrates and film transistor matrix substrate that liquid crystal layer is sandwiched in wherein, this design architecture will limit the development of LCD miniaturization.
