A row electrode driving circuit for a display apparatus. |
摘要 |
<p>An improved row electrode driving circuit can drive a matrix type display apparatus without necessitating digital signals transmitted between partial row electrode driving circuits. Each of the partial row electrode driving circuits is allocated with a number. In each of the partial row electrode driving circuits, shift register shifts a pulse signal to sequentially output it from a plurality of outputs. At each time when a predetermined number of clock pulses have been counted, a count signal is produced. When the shift direction is set to the upper direction, a signal indicating the allocated number is produced. When the shift direction is set to the lower direction, a signal indicating a number which is obtained by subtracting the allocated number from a specified number is produced. When this number and the clock pulse count number satisfy a predetermined relationship, the pulse signal is output.</p> |
