Abstract
PURPOSE: To establish the circuit simple and less in power consumption and error, by making equal the conduction time of the sampling circuit every data line for the matrix type video display to the time distance of video sampling point assigned to the video signal.
CONSTITUTION: The shift register 19 of the data sampling circuit of the matrix type video display unit is constituted with one stage of delay FF to each data line. In this case, the pulse width of the input timing data 23 is in agreement with the one period of the clock signal 22 determining the sampling points a,b,c... of the video signal 15 or a multiple so that the output is made to the terminals 27, 28, 29... The data sampling pulse 24 or 25 from the terminals 27, 28... keeps the ON time of the gate 30 so that they are all equal to the sampling period or a multiple. Thus, the leading and trailing of each pulse are contacted with the leading and trailing before and after to obtain sampling circuit less in error.
