Description
Technical field
The present invention relates to 3 d display device, particularly a kind of polarization type 3D liquid crystal display with phase retardation film.
Background technology
Polarization type 3D liquid crystal display shows to realize 3D by arranging the phase delay device matched with polarization type glasses.Polarization type 3D liquid crystal display presses the set-up mode of phase delay device, be divided into two kinds: GPR (PatternedRetarderonGlass, also GPR is claimed) polarization type 3D liquid crystal display and FPR (PatternedRetarderonFilm also claims FPR) polarization type 3D liquid crystal display.
As shown in Figure 1, be the structural representation of GPR polarization type 3D liquid crystal display.This 3D liquid crystal display comprises phase delay structure A and the liquid crystal display B of stacked setting, the phase delay device 102 that this phase delay structure comprises glass substrate 101 and is arranged on glass substrate 101; Liquid crystal display B has common LCD structure, comprises the upper polaroid 103 that is cascading, upper substrate 104, colored filter 105, ITO layer 106, upper both alignment layers 107, liquid crystal layer 108, lower both alignment layers 109, TFT110, infrabasal plate 111 and lower polaroid 112.Polaroid 103 on this, upper substrate 104, colored filter 105, ITO layer 106, upper both alignment layers 107, liquid crystal layer 108, lower both alignment layers 109, TFT110, infrabasal plate 111 and lower polaroid 112.Phase delay structure A attaches the outside surface with this liquid crystal display B upper substrate 104, and phase delay device 103 and upper substrate 104 fit tightly.The light that backlight module (not shown) sends is successively through lower polaroid 112, and the liquid crystal layer 108 of liquid crystal panel and upper polaroid 103 arrive the eyes of observer after modulating finally by phase delay device 102 and upper glass 101.Observer, by wearing the polarising glass matched with phase delay device 102, watches stereo-picture.
In GPR polarization type 3D liquid crystal display, upper substrate 104 interval is had between the pixel that in phase retardation film 102 and TFT layer 210, each TFT is corresponding, like this, when observer watches 3D rendering, only can see good 3D effect in the scope that perpendicular to liquid crystal display B is less, if angle is larger a little, observer watches the pixel of dislocation through phase retardation film 102, cause image 3D effect poor, even cannot watch 3D effect.And upper substrate 104 thickness is thicker, 3D rendering vertical angle of view is less; Although thinning upper substrate 104 can strengthen vertical angle of view, can holistic cost be improved, and glass thinner is in the fabrication process easily damaged, reduces yield.
