Paper Abstract

This paper reports on a 50 inch diagonal autostereoscopic full-color 3-D TV display system that requires no special glasses and uses four color TV cameras with a 3-D color viewfinder, a high-resolution liquid crystal (LCD) video projector, and a specially designed lenticular screen. The resulting 3-D image is of high resolution, exceptionally bright and vividly three- dimensional. The key technologies supporting this 3-D TV display system are a 3-D image display method, a newly developed HDTV LCD color video projector with incredibly high resolution (4.5 million pixels), and a new type of lenticular screen with a `hollow structure.' Images from four color TV cameras are recorded by four professional VTRs with a time code signal, and are multiplexed, pixel by pixel, to form a vertical stripe image projected by the single LCD video projector behind the lenticular screen. Using this 3-D image display method, optical alignment between the projected stripe image and lenticular screen is both accurate and easily attained. The new lenticular screen with hollow structure has resulted in a reduced total screen weight and thickness with increased light transmittance.
