Abstract
We have developed a 1-inch diagonal transflective 2D/3D-LCD with a novel pixel arrangement, called HDDP (Horizontally Double-Density Pixels). In the HDDP arrangement, both horizontal and vertical resolutions are equal, which not only results in high 3D image quality, but also means that 2D images, such as characters, can be displayed perfectly. With this design, both 3D and 2D images can be displayed simultaneously in the same picture with no need for 2D/3D mode-conversion. In order to avoid increasing power consumption, we chose to use a lenticular lens and a transflective mode which employs ambient light. In transflective mode, so as not to reduce the 3D visible zone, we use a horizontal stripe reflector, which divides each dot into a transmissive region and a reflective region vertically, without dividing the 3D visible zone into transmissive or reflective zones. As a result, a wide 3D visible zone has been achieved. In addition, in order to avoid image degradation caused by a combination of a micro structure on the reflector and a lenticular lens, we optimized the micro structure and defocused the lenticular lens. Its small size, high visibility and lowpower consumption can broaden the applications of 3D displays.
