Fig. 11 shows the block diagram of the module's circuitry.
6-2. Display face configuration The display consists of 640 X 240 dots as shown in Fig. 2. The interface is single panel with single drive to be driven at l/240 duty ratio.
6-3. `Lnput data and cqntrol signal The LCD driver is 160 bits LSI, consisting of shift registers, latch circuits and LCD driver circuits. Display data which are externally divided into data for each row (640 dots) will be 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 input of one row (640 dots) is completed,
the data will be latched in the form of parallel then, the corresponding drive signals
data for 640 lines of signal electrodes by latch signal (CPl) will be transmitted
to the 640 lines of column electrodes of the LCD panel by the LCD drive circuits.
At this time, scan start-up signal (S) has been transferred from the scan signal driver to the 1st row of scan electrodes, and the contents of the data signals are displayed on the 1st rows of the display face according to the combinations of voltages applied to the scan and signal electrodes of the LCD.
While the 1st rows of data are being displayed, the 2nd row of data are entered. When 640 dots of data have been transferred, they latched on the falling edge of CPl clock, the display face proceeds to the 2nd rows of display.
Such data input will be repeated up to the 240th row of each display segment, from upper row to lower
rows,
to complete
one frame of display by time sharing method.
Then data input proceeds to the next display frame.
Scan start -up signal S generates scan signal to drive horizontal
electrodes.
Since DC voltage, if applied to LCD panel, causes chemical reaction which will deteriorate drive wave-form shall be inverted at every display frame to prevent the generation Control signal M plays such a role.

of the CMOS driver LSI, the power consumption
of the display module goes up
as the operating frequency CP2. Thanks to the 4 lines of shift registers to reduce the data transfer speed CP2 Thanks to the LSI, the power consumption of the display module will be minimized.
In this circuit configuration,
4-bit display data shalI be therefore input to data input pins of DO -3.
Furthermore,
the display module has bus line system for data input to minimize
the power consumption
with

of each driver LSI being activated only when relevant data input is fed.
Data input for column electrodes and chip select of driver LSI are made as follows:
The driver LSI at the left end of the display face is first selected, and the adjacent driver LSI of the right next side is selected when data of 160 dot (4OCP2) is fed. This process is sequentially fed to the driver LSI at the right end of the display face. continued until data is
Thus data input will be made through 4-bit bus line sequentially Since this display module contains no refresh RAM, static display.
