Abstract: A high-resolution stereoscopic display device for displaying an image of an interlace type is provided to use a general LCD panel without using a high response LCD of a high price. A polarizing plate(32) is disposed in a front surface of a backlight unit(31). An LCD panel(37) alternately interlaces and displays a left-eye image and a right-eye image by one pixel line. A lenticular lens sheet(35), disposed between the polarizing plate(32) and the LCD panel(37), divides a beam emitted from the backlight unit(31) into a left-eye field and a right-eye field and progresses the divided beams. A polarizing switch includes a spatial light modulator(33) and the first and the second birefringence element arrays(34,36). The polarizing switch, synchronized to the vertical scanning time of the LCD panel, controls a polarizing direction so that a beam progressed to the left-eye field is inputted to a pixel line of the LCD panel(37) which displays the left-eye image. The polarizing switch controls the polarizing direction so that a beam progressed to the right-eye field is inputted to a pixel line of the LCD panel(37) which displays the right-eye image.

Abstract: A method and an apparatus for adjusting the quality of a three-dimensional stereo image by using a communication channel are provided to adjust the quality of three-dimensional image signals by an input unit attached to a display device, and automatically adjust the optimum depth of images by measuring a distance between a user and the display device when the user does not know functions of the display device or does not fully understand appropriate depth and quality adjustment. A distance measuring unit(222) measures a distance between a user(210) and a display device(220) connected with a three-dimensional image signal generator(230) by a communication channel. A disparity generator generates a disparity value corresponding to the measured distance value. A transmitting and receiving unit transmits the generated disparity value to the three-dimensional image signal generator through the communication channel.
