Main advantages of using aperture grille include no reflection and no absorption in apertures, as well as wide viewing angle. These advantages are investigated with theoretical calculations and experiments by use of several kinds of LED panels, such as a fine-pitch LED panel and a 140-inch large LED panel. Limitations of viewing angle by parallax barrier are analyzed in conventional black stripes on a transparent substrate type and in aperture grille type. Experimental results straw use of aperture grille increases contrast and reduce reflection on the aperture surface.展开更多

Some key techniques including stereo display processing and high precision video scaling based bicubic interpolation, and their hardware implementations which improve the image quality are presented. The proposed HMD100 chip is verified by the field-programmable gate array (FPGA). As one of innovative and high integration SoC chips, HMD100 is designed by a digital and analog mixed circuit. It can support binocular stereo display, has better scaling effect and integration. Hence it is applicable in virtual reality (VR), 3D games and other microdisplay domains.展开更多
