High image quality 3D displays with polarizer glasses based on active retarder technology

摘要

In this study, we proposed methods to reduce a black-white (BW) 3D crosstalk and gray-to-gray (GtoG) 3D crosstalk in active retarder 3D (AR3D) technology. To obtain the BW 3D crosstalk to 2.5% without backlight scanning, we first optimized the switching time of AR panel. Then, the BW 3D crosstalk of 1.0% was achieved by scanning the backlight synchronized with the liquid crystal display (LCD) panel and AR panel. Finally, with the over-driving method for various condition of gray-to-gray transition, the average GtoG 3D crosstalk was obtained to be under 1.8% showing clear 3D images. With these concepts of reducing the 3D crosstalk in AR3D technology, we developed AR3D monitor having 23 inches in diagonal with full HD resolution. The luminance of our prototype is 73 nits at 3D mode through polarizer glasses and 300 nits at 2D mode for bare eyes, showing that 24% light efficiency in 3D mode. In conclusion, our prototype shows clear 3D image with full HD resolution and high luminance even though it employs polarizer glasses.
