Fig. 5 shows the display device according to filter for display device shown in Fig. 4 a of an exemplary embodiment and the 4b.
Go out as shown in Figure 5, display device comprises display panel 200 and filter for display device 110.
Display panel 200 can comprise the panel of LCD (LCD) for example or Plasmia indicating panel flat-panel monitors such as (PDP).For example, display panel 200 comprises front panel 210 and rear panel 220, between them to give set a distance joined in parallel relative to one another.Front panel 210 comprises the prebasal plate 211 as the display surface of display image.Rear panel 220 comprises the metacoxal plate 221 of forming the rear surface.A plurality of scan electrodes 212 and a plurality of electrode 213 of keeping are formed on the prebasal plate 211 in pairs, to form a plurality of electrode pairs of keeping.A plurality of data electrodes 223 are arranged on the metacoxal plate 221, with keep electrode pair and intersect.
Scan electrode 212 and keep electrode 213 and between them, generate mutually discharge in a discharge cell, and keep the light emission of discharge cell.Scan electrode 212 and keep electrode 213 each all comprises the transparency electrode 212a that made by transparent ITO material and 213a and the bus electrode 212b and the 213b that are made by metal material.In addition, scan electrode 212 and keep electrode 213 each can only comprise transparency electrode or only comprise bus electrode.Scan electrode 212 and keep electrode 213 and be coated with one or more upper dielectric layers 214 is to be used to limit discharge current and to provide insulation between the electrode pair keeping.Have the sedimental protective seam 215 of magnesium oxide (MgO) and be formed on the upper surface of upper dielectric layer 214 to promote discharged condition.
The barrier rib 222 of a plurality of bar shapeds or well shape forms on the metacoxal plate 221 of plate 220 in the back parallelly, to form a plurality of discharge spaces, that is, and a plurality of discharge cells.Be used for carrying out address discharge and be parallel to barrier rib 222 layouts to generate vacuum ultraviolet a plurality of data electrode 223.The upper surface of metacoxal plate 221 scribbles red (R), green (G) and blue (B) phosphor 224, and emission is used for the visible light that image shows during address discharge generates to be used for.Between data electrode 223 and phosphor 224, form lower dielectric layer 225 with protected data electrode 223.
So front panel 210 that forms and rear panel 220 use the seal process combination to finish display panel 200.The driver (not shown) of be used for driven sweep electrode 212, keeping electrode 213 and data electrode 223 is attached on the display panel 200.
Filter for display device 110 is placed on the front of display panel 200, and comprises the film 100 shown in Fig. 1.The first 101 of film 100 is along with having bigger cross-sectional area to display panel 200.
Because the refractive index of the first 101 of film 100 is greater than the refractive index of the second portion 102 of film 100, so first 101 has hindered outside reflection of light and suppressed ghost phenomena.Therefore, the contrast of display device is improved.
Fig. 6 schematically shows the xsect of display device shown in Figure 5.Fig. 7 a and 7b are the view of the ghost phenomena that generated when being used for explaining display image.
With reference to figure 6 and Fig. 7 a and 7b, the image light of launching from the regional A of display panel 200 transmits by second portion 102, and the beholder watches image light at regional A ' by his eyes subsequently.Yet when the image light from regional A emission was incident in the first 101 by second portion 102, because the refractive index of first 101 and the refractive index of second portion 102, the image reflection of light changed.In other words, when the refractive index of second portion 102 during greater than the refractive index of first 101, by second portion 102 be incident on image light in the first 101 in first by total reflection.In this case, the beholder will be identified as from the image light of regional A emission from the image light of the regional A ' emission of display panel 200.This is a ghost phenomena, and wherein image moves on screen or the doubling of the image overlapping, shown in Fig. 7 a.
Yet,, be incident on not total reflection in first 101 of image light in the first 101 by second portion 102 when the refractive index of first 101 during greater than the refractive index of second portion 102.In other words, although because poor between the refractive index of the refractive index of first 101 and second portion 102, make that the image light that is incident in the first 101 by second portion 102 is partly reflected in first 101, but because the total reflection condition of image light does not satisfy, thereby image light is not by total reflection in first 101.Correspondingly, ghost phenomena be suppressed and on display panel 200 the clear display image, shown as Fig. 7 b.
Fig. 8 is the figure of emission efficiency of image light that depends on the refractive index of film for display.
As shown in Figure 8, when the refractive index of second portion 102 is 1.5 and the refractive index of first 101 during less than the refractive index of second portion 102, from the image light of display panel 200 emissions first 101 by total reflection.Therefore, the transmission of display panel 200 increases, and maintains predetermined value (for example 87.0%) subsequently.As mentioned above, when the transmission owing to total reflection display panel 200 improved, the contrastive feature of display device improved.Yet this causes ghost phenomena.Arrow B among Fig. 8 has been indicated the generation direction of the total reflection of image light in first 101.
On the other hand, when the refractive index of first 101 during greater than the refractive index of second portion 102, from the image light of display panel 200 emission first 101 not by total reflection, because poor between first's 101 refractive indexes and second portion 102 refractive indexes, reflection from the image of display panel 200 emission in first 101 increases, and the transmission of display panel 200 increases.Therefore, the contrastive feature of display device is improved.Yet, when the refractive index of first 101 when the refractive index of second portion 102 increases continuously, the image reflection of light increases in first 101.This can cause ghost phenomena.
Therefore, the refractive index of first 101 greater than with 1.3 times of the refractive index that is equal to or less than second portion 102.
The direction that the image reflection of light increases in the arrow A indication first 101 among Fig. 8.
As mentioned above, improved contrastive feature according to the display device of exemplary embodiment by the emission efficiency of the image light of increase display panel, and suppressed ghost phenomena by the refractive index of control film for display.Thereby the picture quality of display device is improved.
Obviously, as above describing the present invention can change in many ways.These change and not to be considered to break away from the spirit and scope of the present invention, and all are conspicuous modifications for one of ordinary skill in the art, and are included in the scope of following claim.
