| Fig. 1 (a) shows conventional structure of 2D/3D convertible LCD and operating principle. d, g, i, and e denote viewing distance, the pixel-barrier separation, the pixel pitch, and the inter-pupillary distance, respectively. Purple and orange dotted lines represent the light rays from the left and right pixels, respectively. (b) Proposed 2D/3D convertible LCD using LPI for the near-viewing distance. (c) Illustration of bi-level structures on both sides of the polarizer sheet. |
