A novel micro-grooved structure of lightguides and a sequential driving scheme of light sources were demonstrated in achieving comparable image qualities of 3-D displays to that of 2-D displays. The modified distribution of micro-grooves not only locates viewing cones for respective eyes but also suppresses the moire pattern, which might occur when a periodic micro-grooved structure and a color filter are superimposed. The configuration of lightguides for a 1.8-in liquid crystal display (LCD) panel can yield acceptable 3-D perceptions at the viewing distance of 7-23 cm and the brightness uniformity of greater than 83%. In addition, the driving scheme of light sources in synchronization with parallax images can project images to the viewer's respective eyes sequentially. With the refreshing sub-frame rate of 190 Hz and double displaying parallax images, the image crosstalk of 3-D perceptions can be efficiently reduced for an LC response time of 7.0 ms.
