Display Face Configuration

The LCD driver is 80 bits LSI, consisting of shift register, latch circuits, and LCD driver circuits. Display data which is externally divided into data for each row (320 dots) is sequentially transferred in the form of 4-bit parallel data through shift registers by Clock Signal CP2 from the left top of the display face.
When data of one row (320 dots) has been input, they are latched in the form of parallel data for 320 lines of signal electrodes by Latch Signal CP1. Then the corresponding drive signal is transmitted to the 320 lines of column electrodes of the LCD panel by the LCD drive circuits.
