For this purpose, the utility model proposes a kind of display device, comprise display panel, backlight and phosphor powder layer, it is characterized in that: described backlight is blue light backlight, be positioned at described display panel below; Described phosphor powder layer is positioned at described backlight top, and described phosphor powder layer comprises many group phosphor combination, and described phosphor combination comprises red fluorescence powder, green emitting phosphor and without the hyaline layer of fluorescent powder.
Preferably, described red fluorescence powder, described green emitting phosphor and described hyaline layer top all have collector lens, for making to incide the optical alignment outgoing of described collector lens.
Preferably, between described red fluorescence powder, described green emitting phosphor and described hyaline layer, by shading framework, separated.
Preferably, between described red fluorescence powder, described green emitting phosphor, described hyaline layer and described collector lens, there is the space being limited by described shading framework, so that described red fluorescence powder, described green emitting phosphor and described hyaline layer are positioned at the place, focal position of described collector lens.
Preferably, described space is being parallel on the cross section of described display panel for square.
Preferably, the lower surface of described shading framework convexes to form groove with respect to the lower surface of described phosphor powder layer.
Preferably, the lower surface of described shading framework and the lower surface of described phosphor powder layer flush.
Preferably, described hyaline layer is cavity.
Preferably, it is outside that described phosphor powder layer is positioned at described display panel, and between described backlight and described display panel.
Preferably, described phosphor powder layer is positioned at described display panel inside.
By adopting according to the display device of the utility model embodiment, white light and the standard white deviation of light that can avoid existing backlight module to send are larger, thereby make the problem of display panel color representation ability, improve the color representation ability of display device, and can reduce the thickness of display device.
Accompanying drawing explanation
By reference to accompanying drawing, can more clearly understand feature and advantage of the present utility model, accompanying drawing is schematically to should not be construed as the utility model is carried out to any restriction, in the accompanying drawings:
Fig. 1 shows the schematic diagram of display device in prior art;
Fig. 2 shows according to the schematic diagram of the display device of the utility model embodiment;
Fig. 3 shows the enlarged diagram of phosphor powder layer in Fig. 2;
Fig. 4 shows backlight by the index path of phosphor powder layer and display panel according to the utility model embodiment;
Fig. 5 shows according to the schematic diagram of the phosphor powder layer of another embodiment of the utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
Fig. 2 shows according to the schematic diagram of the display device of the utility model embodiment.As shown in Figure 2, the form at a plurality of blue-ray LEDs 21 with matrix array is arranged on Reflecting backboard 24, and the light that blue-ray LED 21 sends incides in phosphor powder layer 22.Preferably, brightness enhancement film 25 and diffusion barrier 26 can be set between blue-ray LED 21 and phosphor powder layer 22, thereby produce blue light backlight illumination even and that shooting angle is less, make display effect better.Phosphor powder layer 22, blue-ray LED 21, Reflecting backboard 24, brightness enhancement film 25 have formed backlight module together with diffusion barrier 26, are arranged on display panel 23 belows, to illuminate display panel 23.
Fig. 3 shows the enlarged diagram of phosphor powder layer in Fig. 2.As shown in Figure 3, the red fluorescence bisque 31 in phosphor powder layer and green phosphor layer 32 can produce ruddiness and green glow by exciting of blue light, and do not have the hyaline layer 33 of fluorescent powder directly to see through blue light.Preferably, hyaline layer 33 is cavity, thereby blue light is directly seen through and without any decay.Between red fluorescence bisque 31, green phosphor layer 32 and hyaline layer 33, by shading framework 34, separated, the lower surface of shading framework 34 convexes to form groove with respect to the lower surface of phosphor powder layer.Between red fluorescence bisque 31, green phosphor layer 32, hyaline layer 33 and collector lens 35, there is the space being limited by shading framework 34, from the monochromatic light of red fluorescence bisque 31, green phosphor layer 32 and hyaline layer 33 outgoing (, red, green, blue) in space 36, propagate, while, its travel path remained in space 36 because shading framework 34 stops and reflect.While seeing space 36 from top to bottom, be parallel on the cross section of display panel, being shaped as of space 36 is square.The effect in space 36 is between phosphor powder layer and collector lens 35, to produce certain distance in order to allow, this distance can so that phosphor powder layer closer to the focal position of collector lens 35, thereby make the collimation better effects if of collector lens 35, make more light can enter into display panel, thereby improve the brightness of display panel.Light through collector lens 35 collimations incides in display panel.
Fig. 4 shows backlight by the index path of phosphor powder layer and display panel according to the utility model embodiment.Enter monochromatic light in display panel by the upper polaroid 43 of lower polaroid 41, liquid crystal cell 42 and the display panel upper surface of display panel lower surface, final light can be with the monochromatic form outgoing of pixel.
Fig. 5 shows according to the schematic diagram of the phosphor powder layer of another embodiment of the utility model.Different from the phosphor powder layer in Fig. 3, the lower surface of shading framework 54 of the phosphor powder layer in Fig. 5 and the lower surface of phosphor powder layer flush and there is no groove structure, thereby can further strengthen the distance between the space that limited by shading framework 54 upper and lower, improve collimation effect.
Described hereinbefore the embodiment that phosphor powder layer is positioned at display panel below, but the utility model is not limited to this.It will be appreciated by those skilled in the art that and phosphor powder layer can also be arranged on to display panel inside, equally also can realize the object that improves color representation ability.
By adopting according to the display device of the utility model embodiment, white light and the standard white deviation of light that can avoid existing backlight module to send are larger, thereby make the problem of display panel color representation ability, have improved the color representation ability of display device.Meanwhile, owing to adopting according to the phosphor powder layer of the utility model embodiment, the light by phosphor powder layer is exactly directly red, green, blue, thereby can save the color membrane substrates in display panel, thereby reduces the thickness of display device.
Although described by reference to the accompanying drawings embodiment of the present utility model, but those skilled in the art can make various modifications and variations in the situation that not departing from spirit and scope of the present utility model, and such modification and modification all fall into by within claims limited range.
