    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.

    Abstract translation: 一种触摸输入系统,其具有CRT,其在四个印刷的书写板上具有相对排列的LED和光电传感器,形成围绕CRT屏幕的框架,并且建立允许识别屏幕被触摸的任何点的格栅,以及电和机械的柔性电路 将电路板角部连接到角部以形成框架。 在替代实施例中,单独的电路部件单独使用或与粘合剂组合使用以将柔性电路机械地附接到电路板。 在另一替代实施例中,代替印刷线路板,使用具有沿框架的四个边中的每一侧的底部支撑件的单件柔性电路。
