This paper discribes a display system which has multi-channel free-hand drawing input tablets. When the charactors or the figures are drawn on the input tablets by free-hand the hoping charactor or figure written on the input tablets can be chosen and displaied on the CRT of TV and oscilloscop, and be projected on the wall using a laser beam scanner at real time. The control of this system bases on the time shearing system ( TSS ) with micro-computer ( Motorola M6800 ). Therewith, the remaining charactors or figures on the input-tablets, which were not chosen and not displaieid, are stored on the memories of the micro-computer. If we want to display those charactors or figures, we can choose the hoping one from the data of the memories, and display on the TV next time. In this experiment, the four channels input tablets are connected and used, simaultaneously. When the TV was used display instrument, the fine results have been taken. Since the software of partial rejection for the error drawing on the input tablets was completed too, this system becomes practical use.
