tic. 7 shows the block diaarar of the kit’s circaitrr.
6. 2 Display Face Configuration
The display face electrically consists of txo (upper and lower) display rements
so that the unit MY offer higher contrast by reducing drive dutr ratio. Each
display segment I840~240 dotal is driven at l/240 duty ratio.
6. 3 Input Data md Control Signal
The LCD driver is 80 bits LSI, consisting of shift registers, latch circnits and
LCD driver circuits.
.
Disola~ data which are externally divided into data for each row (64Odots) will
be sequentially transferred in the forr of I-bit parallel data through shift
registers by Clock Signal CP3 from the left top of the display face.
Vhen data of oae row (84Odotsl have been input, they will be latched in the form
of parallel data for 640 lines of signal eltetrbdes bt latch signal CPL. Thea the
corresponding drive signal will be transaitted to the 640 liars of colurn electrodes of the LCD panel bt the LCD drive circuits.
At this tire, scan start-or signal S hu been transferred fro8 the scan signal
driver to the 1st row of SCM electrodes, and ths corteots of the data signals are
disulared oa the ist row of upper ad low half of the display face according to
the combinations of voltages apelied to t&o scan and signal electrodes of the LCD.
While the 1st ron of data we bring displayed, the 2nd row of data are eatered.
Thea 640 dots of data hrvo beea transferred thaa latched oa the falling cdce of
CPl clock, t&e display face proceeds to the 2nd row of display.

IIPPW to lower rovs.to couleto one frw of display bt tiu shrriu uthad. Then
data Mat proceeds to the next displrr face.
Scan start-w signal S generates scaa signal
to
drive horizontal electrodes.
Siace DC voltage, if applied to LCD panel, causes chemical reaction which will
deteriorate LCD panel, drive nrefon &all bs inverted rt every divlar frur to
prevent the generation of such DC voltage. Control Signal H plays srch role.

Because of the characteristics of $8 QlOS driver LSI, the cower conrurption of
t&o aait cots aa as the operating frapoeocr CP2 increases. Thus the driver IS1
saplies the snter of trrafsrrinc (-bits parallel data through the 4 lines of
shift registers to reduce the drtr transfer speed CP2. Thanks to the LSI, the
power coasuaptioa of the unit xi11 be rinirired.
Io this circuit aonfimation, I-bit dispk data shall be therefore input to
data input pins of DUO-~ (upper displar secaentl sad DLo-3 (lower display secaentl.
Furthermore the LCD unit adopts bus line srster for data input to ainiaize the
power coasprption, In this srster date input terrinel of each driver LSI rctivrted
.
on& when relevant data input’ is fed.
Data input for columa electrodes of both the upper and ths lower displrr sacmat
and chip select of driver IS1 are ude us follows:
The driver_LSi at the left end of the diealu fro is first selected, and the
adjacent driver LSI of the right side is selected whaa 80 dots dstr (2OCPZl is
fed. This process is sequeatiallr continued until data is fed to the driver IS1 at
the right end of the display fret.
This process is sirultaaeousl~ follored rt the colum drivers LSI’s of both the
upper and the lorer dieplu solrents. T&us data inpat for both the upper sad the
lower dieplrr repeats rust be fed through kbit bus line sequentiallr fro; the
left end of the dirplrt face.
Sinca this grwhic displrr oait coatrire no ret leeh WI. it requires dutu uud
timia# prlee irmte even for static dieplu.
