Parallax-Barrier Type Stereoscopic Display Apparatus
The parallax-barrier type stereoscopic display apparatus is equipped with a light source module comprising a red (R) light source, a green (G) light source and a blue (B) light source, and a light diffusion plate for diffusing lights generated by said light source module. Said parallax-barrier type stereoscopic display apparatus also comprises: an emitting light module which displays each colored light generated from each colored light source by said light source module per unit time (T 1 ) on the entire light-outputting surface of said light diffusion plate in sequence; a display panel in which pixels for the left eye and pixels for the right eye are arranged one after the other with pixel unit, and also which adjusts with pixel unit the penetrating amount of each colored light displayed in sequence by said emitting light module according to image signals, So as to display images for the left eye and images for the right eye arranged one after the other; and a barrier which is disposed with a predetermined distance from said display panel so as to selectively show images for the left eye and images for the fight eye; and thus said parallax-barrier type stereoscopic display apparatus can present images with the high resolution of picture images even on a small screen, owing to the capability of displaying stereoscopic images with pixel units by displaying R, G and B in sequence at each pixel according to image signals.
1 . A parallax-barrier type stereoscopic display apparatus comprising:
an emitting light module for displaying plurality of colored lights in sequence per unit time (T 1 );
a display panel, in which pixels for the left eye and pixels for the right eye are arranged one after the other with pixel units, and which adjusts with pixel unit the penetrating amount of each colored light displayed in sequence by said emitting light module, so that images for the left eye and images for the right eye which are arranged one after the other are displayed; and
a barrier which is disposed with a predetermined distance from said display panel and selectively shows images for the left eye and images for the right eye.
2 . The apparatus according to claim 1 ,
wherein said emitting light module comprises a light source module including plurality of colored-light sources, and a light diffusion plate for diffusing lights generated by said light source module, and
wherein each colored light source of said light source module generates each colored light per the unit time (T 1 ), and sequentially display them on the entire light-outputting surface of said light diffusion plate.
3 . The apparatus according to claim 1 or claim 2 ,
wherein said plurality of colored lights includes red (R) light, green (G) light and blue (B) light, and
wherein said plurality of colored-light sources comprises red (R) light source, green (G) light source and blue (B) light source.
4 . The apparatus according to claim 1 or claim 2 ,
wherein pixels of said display panel adjusts the penetrating amount of each colored light within the unit time (T 1 ), per time (T 2 ) unit represented by the unit time (T 1 ) multiplied by the number of each colored light (N) included in said emitting light module, so as to be able to display images for the left eye at the pixel for the left eye and images for the right eye at the pixel for the right eye.
5 . The apparatus according to claim 1 or claim 2 ,
wherein said barrier exclusively used for stereoscopic view
6 . The apparatus according to claim 1 or claim 2 ,
wherein said barrier comprises TN-LCD or STN-LCD for converting modes of plane/stereoscopic view.
7 . The apparatus according to claim 1 or claim 2 ,
wherein said barrier comprises a blocking shield arranged at every two pixels in the vertical direction.
8 . The apparatus according claim 7 ,
wherein the pitch of said blocking shield can be determined within the range of Pp×0.4 to Pp×0.8 when Pp is determined within the range of 2×Dp×0.8 to 2×Dp;
wherein said Pp is a panel pitch, and said Dp is dot pitch of a pixel; and
Pp=2×Dp×(S−L)/S while S is the viewing distance; and L is the distance between the display panel and the barrier.
