54.1: A Low-Power SOG LCD with Integrated DACs and a DC-DC Converter for Mobile Applications

A low-power 262k-color SOG (System-On-Glass) LCD has been developed for mobile applications. It is integrated with a DC-DC converter and driver circuits that contain 6- bit DACs, and it consumes less than 5 mW in operations with a single voltage power supply of 2.5 V.

A 470 × 235-ppi poly-Si TFT-LCD for high-resolution 2-D and 3-D autostereoscopic displays

— We have developed a 470 × 235-ppi poly-Si TFT-LCD with a novel pixel arrangement, called HDDP (horizontally double-density pixels), for high-resolution 2-D and 3-D autostereoscopic displays. 3-D image quality is especially high in a lenticular-lens-equipped 3-D mode because both the horizontal and vertical resolutions are high, and because these resolutions are equal. 3-D and 2-D images can be displayed simultaneously in the same picture. In addition, 3-D images can be displayed anywhere and 2-D characters can be made to appear at different depths with perfect legibility. No switching of 2-D/3-D modes is necessary, and the designs thin and uncomplicated structure makes it especially suitable for mobile terminals.
