Paper Abstract

While electronic technology has evolved enormously, there are no displays which are both very large and of high resolution. This paper describes our 6 K X 2 K, 60 inch by 20 inch, display prototype which consists of three 2 K X 2 K CRT displays connected seamlessly. Using a custom frame and a half-silvered mirror, the three images are joined by reflecting the center display image from above and transmitting the two side display images directly. Two problems must be solved to achieve a truly seamless effect. First, viewers can still see seams between regular screen images even if the displays are strictly aligned. Second, each physical display has a different geometrical space, and the center display image must be drawn in reverse because it will be reflected by the mirror. We developed a seamless window system to solve these problems. The window system displays overlapping images with translucent borders to enable better blending of the three display screens. Custom application software treats the system as a single 6 K X 2 K area. A concept named ''virtual framebuffer architecture'' enables us to implement the two kinds of seamlessness easily. To evaluate the visual effects, we developed some application systems which include video in a window, stereo sound and a high speed channel to the Connection Machine II for image processing.
