Tilted LCD Pixel With Liquid Crystal GRIN Lens for Two-Dimensional/Three-Dimensional Switchable Display

In this paper, high images quality switchable two-dimensional (2-D)/3-D display is achieved by carefully matching the high-resolution liquid crystal display (LCD) pixel structure and liquid crystal graded index (GRIN) lens. A parallelogram LCD pixel structure is proposed, in which the edges of each sub-pixels are slanted. At the top of the LCD pixels, the liquid crystal GRIN lens is also tilted to reduce the moiré effect and the tilt angle is carefully aligned with the edges of subpixels of LCD. This accurate alignment is useful to eliminate the crosstalk and improves the imaging quality of 3-D display. The 2-D/3-D switchable display is realized by tuning the liquid crystal in the GRIN lens. Based on this, a 3-D display based on 32-inch 8K4K resolution LCD display and Liquid crystal GRIN lens was designed.
