Precautions
1) Industrial (Mechanical) design of the product in which this LCD module will be incorporated must be made
so that the viewing angle characteristics of the LCD may be optimized.
This module’s viewing angle is illustrated in Fig.1.
Please consider the optimum viewing conditions according to the purpose when installing the module.

Since the front polarizer is easily damaged. Please pay attention not to scratch on its face.
3)
It is recommended to use a transparent acrylic resin board or other type of protective panel on the surface of
the LCD module to protect the polarizer, LCD panel, etc..
If the surface of the LCD panel is required to be cleaned, wipe it swiftly with cotton or other soft cloth.
4)
If it is not still clear completely, blow on and wipe it.
Water droplets, etc. must be wiped off immediately since they may cause color changes, staining, etc.,

7) Since CMOS LSIs are equipped in this module, following countermeasures must be taken to avoid
electrostatics charge.
l-Operator
Electrostatic shielding clothes shall be had because it is feared that the static electricity is electrified to
human body in case that operator have a insulating garment.
2.Equipmeot
There is a possibility that the static electricity is charged to equipment which have a function of peeling or
mechanism of friction(EX: Conveyer, soldering iron, working table), so the countermeasure(electrostatic
earth:1 X lo8 Q) should be made.
3.Floor
Floor is a important part to leak static electricity which is generated from human body or equipment.
There is a possibility that the static electricity is charged to them without leakage in case of insulating
floor,so the countermeasure(electrostatic earth: 1 X 10’ Q ) should be made.
4.Humidity
2
Humidity of working room may lower electrostatics generating material’s resistance and have something to
prevent electrifying. So, humidity should be kept over 50% because humidity less than 50 % may increase
material’s electrostatic earth resistance and it become easy to electrify.
S.Transportation/storage
The measure should be made for storage materials because there is a possibility that the static electriicity,
which electrify to human body or storage materials like container by friction or peeling, cause the dielectric
charge.
6.0thers
The laminator is attached on the surface of LCD module to prevent from scratches, fouling and dust.
It should be peeled off unhurriedly with using static eliminator.
And also, static eliminator should be installed to prevent LCD module from electrifying at assembling line.
8) Don’t use any materials which emit gas from epoxy resin(amines’
agent(dealcohol or deoxym) to prevent change polorizer color owing to gas.
9) Avoid to expose the module to the direct sun-light, strong ultraviolet light, etc. for a long time.
10) If stored at temperatures under specified storage temperature, the LC may freeze and be deteriorated.
If storage temperature exceed the specified rating, the molecular orientation of the LC may change to that of
a liquid, and they may not revert to their original state. Therefore, the module should be always stored at norma
hardener) and silicon adhesive
room temperature.
11) Disassembling the LCD module can cause permanent damage and should be strictly avoided.

12) Do not use touch TCP/LCD connection area to prevent interconnection breakdown.
13) Do not apply organic solvent to TWLCD connection area where organic materials are used.
14) This specification describes display quality in case of no gray scale. Since display quality can be affected by
gray scaIe methods, display quality shall be carefully evaluated for the usability of LCD module in case gray
scale is displayed on the LCD module.
15) The module should be driven according to the specified ratings to avoid permanent damage.
DC voltage drive leads to rapid deterioration of LC, so ensure that the drive is alternating waveform by
continuous application of the signal M. Esneciallv the Dower ON/OFF seauence shown on Pave 22 should be
kent to avoid latch-un of drive LSI and application of DC voltape to LCD Dane1

6. Module Driving Method
6-l. Circuit configuration
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.
SPEC No. MODEL No.
LC99404 LM7MS623
PAGE
14
When input of one row (640 dots) is completed, the data will be latched in the form of parallel
data for 640 lines of signal electrodes by latch signal (CPl) then, the corresponding drive signals
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
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.
1st
row of scan
Since DC voltage, if applied to LCD panel, causes chemical reaction which will deteriorate LCD panel.
drive wave-form shall be inverted at every display frame to prevent the generation of such DC voltage.
Control signal M plays such a role.

SHARP
Because of the characteristics 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
data input termin& 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 continued until data is
LC99404 Livl7MS623
15
fed to the driver LSI at the right end of the display face.
Thus data input will be made through 4-bit bus line sequentially from the left end of the display face.
Since this display module contains no refresh RAM, it requires the above data and timing pulse inputs even for
static display.
The timing chart of input signals are shown in fig. 3 and Table 7.
