Abstract
A touch input system having a CRT with opposing rows of aligned LED's and photosensors on four printed writing boards forming a frame about the CRT screen and which establishes a grid permitting any spot where the screen is touched to be identified, and flexible circuits electrically and mechanically attaching the boards corner to corner to form the frame. In an alternate embodiment, individual circuit components are used, either alone or in combination with adhesive to mechanically attach the flexible circuits to the boards. In another alternate embodiment, a one piece flexible circuit with underlying supports along each of the four sides of the frame is used in place of the printed wiring boards.
