Abstract
A stereoscopic display device with liquid crystal shutter light filter for naked eye viewing which comprises a personal computer and an image screen, wherein a dual display card is disposed inside the personal computer, and a light filtering screen is disposed in front of the image screen, and both the image screen and the light filtering screen connect with the dual display card respectively. Input the three-dimensional model data of a stereo image to the dual display card of the personal computer; and set the light filtering data and control the light filtering screen to open light filtering apertures correspondingly to obtain a light filtering image, and then use region projection method to record the stereo image as divided into partitions and obtain a continuous parallax image data, and then perform image processing on the continuous parallax image data to obtain a continuous parallax image, and the light filtering image and the continuous parallax image form a recording unit of the stereo image. Display the continuous parallax image on the image screen and the light filtering image on the light filtering screen simultaneously by the dual display card to see stereo image. The …
