Super video graphics array

Abstract: The present invention relates to a system and method of viewing pairs of perspective images of 3-D objects (i.e. stereoscopic image pairs) displayed from a CRT display surface in a time-multiplexed or field-sequential manner, and more particularly to a universal method of generating control signals for synchronously changing the optical state of liquid crystal (LC) shutter panels through which the time-multiplexed perspective. images can be sequentially viewed in a substantially flicker-free manner by the left and right eyes of a human viewer, independent of whether the images are displayed on NTSC, PAL, VGA or SVGA styled CRT display devices.

Abstract: An interface for a high-performance graphics adapter is provided. In a computer system which includes a host processor, a coprocessor in the form of a graphics system processor, and memory addressable by both the host and coprocessors. An application computer program running on the host processor utilizes a graphics operating system, such as an Extended Graphics Array Input/Output System (XGA BIOS) to write graphics data in XGA format to the memory. A totally awesome controller translates memory addresses generated by the XGA BIOS (and hence the host processor) into memory addresses recognized by the coprocessor. One or more graphics controllers selectively swap pixel data between Intel order and Motorola order and store the graphics data, into an XGA video-random-access memory (RAM) buffer. A back-end gate array parallel-serial converts input display data in units of designated pixel data, and the graphics data is displayed on a CRT.

Abstract: A conferencing server 22 and methods for use with a video conferencing system 20 for multimedia collaborative conferencing. The conferencing server 22 includes at least two data ports 69 and at least two video graphics input ports 67 , each pair of data and video graphics input ports for connecting to one of at least two computers 72 belonging to a participant located in a local video conference room. The conferencing server 22 also includes a video graphics output port 77 for connecting to a local input port 40 of the video conferencing system 22 . The conferencing server 22 includes a control unit 50 that is selectively programmed to couple a first of the at least two video graphics input ports 67 to the video graphics output port 77 for allowing the transfer of information from the computer connected to the first of the at least two video graphics input ports to the video conferencing system 20 . In some specific embodiments, the video graphics input and output ports are SVGA input and output ports.

Abstract: We developed 0.7 inch VGA TFT-OLED with a 64 gray-scale integrated driver circuit. The TFT-OLED has good image uniformity due to digital operation. Control in a time-ratio was useful for achieving large gray-scale level. Our simplified pixel configuration accomplished high resolution.
