A stereoscopic image display apparatus and method which reduce crosstalk and select either high resolution images or bright images. The stereoscopic image display apparatus includes first and second image forming areas, each area including multiple contiguous horizontal rows. The areas are alternately disposed in a liquid crystal display, and display right and left eye images on the first and second image forming areas, respectively. The display displays the images in a fixed manner or replaces or overwrites the image areas every time a frame is switched, and displays a frame image in which the right and left eye images are simultaneously displayed. When the first and second image forming areas are alternately replaced, according to the frame switching timing, the backlight is controlled to turn on and phase difference states of right and left eye glasses of polarized eyeglasses are alternately replaced. |

1. A stereoscopic image display apparatus comprising:
a liquid crystal display which comprises a liquid crystal panel including a plurality of horizontal rows of pixels, the horizontal rows being arranged in a vertical direction of the liquid crystal display, and a pair of polarizing plates which sandwich the liquid crystal panel; a backlight located at a back surface of the liquid crystal display; an optical unit located at a front surface of the liquid crystal display; polarized eyeglasses, including a right eye glass and a left eye glass, having controllable polarization states, wherein a viewers wears the polarized eyeglass in viewing images on the liquid crystal display through the optical unit; a control apparatus which controls image display on the liquid crystal display, turning on and off of the backlight, and states of polarization of the left and right eye glasses of the polarized eyeglasses, wherein
the liquid crystal display comprises a plurality of first image forming areas and a plurality of second image forming areas,each of the first and second image forming areas includes a plurality of contiguous horizontal rows of pixels of the liquid crystal panel,the first and second image forming areas alternate in the vertical direction of the liquid crystal display, andthe control apparatus, controls the liquid crystal display to display, simultaneously, one of a right eye image and a left eye image on each of the first image forming areas, and to display the other of the right eye image and the left eye image on each of the second image forming areas,the control apparatus controls the first image forming areas and the second image forming areas so that,
(1) each time a frame is switched, the right eye image replaces the left eve image that was displayed on one of the first and second image forming areas, and the left eye image replaces the right eye image that was displayed on one of the first and second image forming areas, and(2) each time a frame is overwritten, the right eye image replaces the left eye image that was displayed on one of the first and second image forming areas, and the left eye image replaces the right eye image that was displayed on one of the first and second image forming areas, or(3) each of the right eye image and the left eye image constantly appear on the same respective first and second image forming areas, without replacement by the other of the right eye image and the left eye image,illumination state of the backlight is controlled according to timing of replacement of the right eye image and the left eye image on the first and second image forming areas,the optical unit includes a plurality of first polarizing areas and a plurality of second polarizing areas which are alternatingly arranged at positions, and have sizes, corresponding to respective first image forming areas and second image forming areas, and (i) one of the first polarizing areas and the second polarizing areas includes a ½ wave plate, or (ii) both of the first polarizing areas and the second polarizing areas include ¼ wave plates having optical axes which are orthogonal to each other, andthe right eye glass and the left eye glass are configured to replace polarization states of the right eye glass and the left eye glass in synchronization with the timing of replacement of the right eye image with the left eye image and the left eye image with the right eye image. |
