Fig. 2 is the structural representation of the utility model LCD one better embodiment.
Fig. 3 is the structural representation of the utility model second polaroid.
[embodiment]
Seeing also Fig. 2, is the structural representation of the utility model LCD one better embodiment.This LCD 200 comprises a display panels 210, one module 220 backlight and a housing 230.This display panels 210 is assembled by housing 230 with module 220 backlight.
This display panels 210 comprises one first substrate 211, one second substrate 213, a liquid crystal layer 212, one first polaroid 214 and one second polaroid 215.This liquid crystal layer 212 is clipped in and forms a viewing area between first substrate 211 and second substrate 213.This first polaroid 214 and second polaroid 215 are separately positioned on first substrate 211 and second substrate, 213 outside surfaces.
First light-collecting piece 221 that this module 220 backlight is arranged in order from top to bottom, second light-collecting piece 222, following diffusion sheet 223, light guide plate 224, light source 225 and reflector plate 226.This first light-collecting piece 221 is arranged on the top layer of module 220 backlight.This light source 225 is cathode fluorescent tubes of several parallel arranged, and it is arranged on this light guide plate 224 downsides.This light source can also be light emitting diode.
Seeing also Fig. 3, is the structural representation of this second polaroid 215.This second polaroid 215 comprises one first protective seam 2151, a polaroid matrix 2152, one second protective seam 2153, a pressure-sensing glue 2154 and a release film 2155 that is cascading from top to bottom; wherein this second polaroid 215 further comprises a diffusion layer 2156, this diffusion layer 2156 and these release film 2155 stacked settings.This diffusion layer 2156 is with the bonding diffusion particle 2157 of transparent colloid (figure does not show) and coats this release film 2155 surfaces that by dry fixing after the UV-irradiation, it has diffusion function again.These diffusion particle 2157 sizes are consistent, and scattering is even, and particle diameter is in the micron number magnitude.
