Rear Cross Lenticular 3D Display without eyeglasses

We have developed a prototype 3D Display system without any eyeglasses, which we call "Rear Cross Lenticular 3D Display" (RCL3D), that is very compact and produces high quality 3D image. The RCL3D consists of a LCD panel, two lenticular lens sheets which run perpendicular to each other, a Checkered Pattern Mask and a backlight panel. On the LCD panel, a composite image which consists of alternately arranged horizontally striped images for right eye and left eye, is displayed.This composite image form is compatible with the field sequential stereoscopic image data. The light from backlight panel goes through the apertures of the Checkered Pattern Mask and illuminates the horizontal lines of images for right eye and left eye on LCD and goes to the right eye position and left eye position separately by the function of the two lenticular lens sheets. With this principle, the RCL3D shows 3D image to an observer without any eyeglasses. We applied simulation of viewing zone,using random ray tracing to the RCL3D and found that illuminated areas for right eye and left eye are separated clearly as series of alternate vertical stripes. We will present the prototype of the RCL3D( 14.5 " ,XGA) and simulation results.
