morpheus83 writes "Sharp Corporation and Sharp Laboratories of Europe, Ltd. (SLE) have developed the Triple Directional Viewing LCD, a display that controls the viewing angle so that the display can show different images from the left, right, and center simultaneously. Using proprietary parallax barrier on a standard TFT LCD, the screen splits light in three directions — left, right, and center — and displays three separate images on the same screen at the same time. So connect three computers to the LCD and from the center you see Windows, Linux from the left and MacOS from the right."
