LCD module functions at the minimum frame cycle of 8.33 ms(Maximum frame frequency of
120 Hz).
Owing to the characteristics of LCD module, “shadowing” will become more eminent as frame
frequency goesup, while flicker will be reduced.
According to our experiments, frame cycle of 8.33 ms Min. or frame frequency of 120 Hz Max.
will demonstrate optimum display quality in terms of flicker and “shadowing”. But since
judgment of display quality is subjective and display quality such as “shadowing” is pattern
dependent, it is recommended that decision of frame frequency, to which power consumption of the
LCD module is proportional, be made based on your own through testing on the LCD module with
every possible patterns displayed on it.
The intervals of one LP fall and next must be always the same, and LPs must be input
continuously.
The intervals must be 70μs Max.

6. Module Driving Method
6-1. Circuit configuration
Fig.9 shows the block diagram of the module’s circuitry.
6-2. Display face configuration
The display consists of 640×3(R,G,B)×480 dots as shown in Fig. 1.
The interface is single panel with double drive to be driven at 1/240(1/244) duty ratio.
(1/240:an odd number frame, 1/244:an even number frame)
6-3. Input data and control signal
The LCD driver is 240 bits LSI, consisting of shift registers, latch circuits and LCD driver
circuits. Input data for each row (640×3 R,G,B) will be sequentially transferred in the
form of 8 bit parallel data through shift registers from top left of the display together with
clock signal (XCK).
When input of one row (640×3 R,G,B) is completed, the data will be latched in the form of
parallel data corresponding to the signal electrodes by the falling edge of latch signal (LP)
then,the corresponding drive signals will be transmitted to the 640×3 lines of column
electrodes of the LCD panel by the LCD drive circuits.
At this time, scan start-up signal (YD) 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
row of the display face according to the combinations of voltages applied to the scan and
signal electrodes of the LCD. While the data of 1st row are being displayed, the data of 2nd
row are entered. When data for 640×3 dots have been transferred, they will be latched by
the falling edge of LP, switching the display to the 2nd row.
Such data input will be repeated up to the 240(244)th row of each display segment, from
upper row to lower rows, to complete one frame of display by time sharing method.
Simultaneously the same scanning sequence occur at the lower panel.
Then data input proceeds to the next display frame.
YD generates scan signal to drive horizontal electrodes.
Since DC voltage, if applied to LCD panel, causes chemical reaction in LC materials,
causing deterioration of the materials, 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.

Because of the characteristics of CMOS driver LSI, the power consumption of the display
module goes up with the clock frequency of XCK.
To minimize data transfer speed of XCK clock the LSI has the system of transferring 8 bit
parallel data through the 8 lines of shift registers.
Thanks to this system the power consumption of the display module is minimized.
In this circuit configuration, 8 bit display data shall input to data input pins of DU0-7 and
DL0-7.
Furthermore, the display module has bus line system for data input to minimize the power
consumption with data input terminals 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 right next side is selected when data of 240 dot (30XCK) is fed. This process is
sequentially continued until data is fed to the driver LSI at the right end of the display
face. This process is followed simultaneously both at the top and bottom column drivers
LSI’s.
Thus data input will be made through 8 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.

10. Cautions
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.12.
θy MIN. < viewing angle <θy MAX.
(For the specific values ofθy MIN., andθy MAX., refer to the table8)
Please consider the optimum viewing conditions according to the purpose when installing the
module.
Viewing direction +θy
θy=0 °(Normal line)
-θy
Panel surface
Fig.12 Definition of viewing angle
2)
This module should be installed using mounting holes of metal bezel. When installing the
module,pay attention and handle carefully not to allow any undue stress such as twist or bend.
3)
Since the front polarizer is easily damaged. Please pay attention not to scratch on its face.
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..
4)
If the surface of the LCD panel is required to be cleaned, wipe it swiftly with cotton or other soft
cloth. If it is not still clear completely, blow on and wipe it.
5)
Water droplets, etc. must be wiped off immediately since they may cause color changes, staining,
etc., if it remained for a long time.
6)
Since LCD is made of glass substrate, dropping the module or banging it against hard objects
may cause cracking or fragmentation.
7)
Since CMOS LSIs are equipped in this module, following countermeasures must be taken to
avoid electrostatics charge.

1. 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. Equipment
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:1×108Ω) 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:1×108Ω) should be made.
4.Humidity
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.
5. Transportation/storage
The measure should be made for storage materials because there is a possibility that the static
electricity,which electrify to human body or storage materials like container by friction or
peeling,cause the dielectric charge.
6. Others
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’ hardener) and silicon
adhesive agent(dealcohol or deoxym) to prevent change polarizer color owing to gas.
9)
Since leakage current, which may be caused by routing of CCFT cables, etc., may affect the
brightness of display, the inverter has to be designed taking the leakage current into
consideration. Thorough evaluation of the LCD module/inverter built into its host equipment
shall be conducted, therefore, to ensure the specified brightness.
10) Avoid to expose the module to the direct sun-light, strong ultraviolet light, etc. for a long time.
11) 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 normal room temperature.
12) Disassembling the LCD module can cause permanent damage and should be strictly avoided.

13) Procedure insert mating connector
When the mating connector is inserted, it should be parallel to the used connector of LCD
module and it should be inserted on horizontal firm base.
When the mating connector is attempted to be fixed to LCD connector, it should be inserted
properly in order not to create a gap as shown following diagram 2).
Please insert the connector as both edge is placed to the connect position of LCD connector.
1)Method of correct insert
Stress is dispersed
Base (horizontal film base) is required
2) Method of wrong insert
Stress is not dispersed

describes
display quality in case of no gray scale. Since display quality can be
affected by gray scale 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. Especially the power ON/OFF sequence
shown on Page 21 should be kept to avoid latch-up of drive LSI and application of DC voltage to
LCD panel
16) It is a characteristic of LCD to maintain the displaying pattern when the pattern is applied for a
long time.(Image retention)
To prevent image retention, please do not apply the fixed pattern for along time by pre-installing
such programs at your side.
17) This phenomenon (image retention) is not deterioration of LCD. If it happens, you can remove it
by applying different patterns.
18) CCFT backlight should be kept OFF during VDD is “L” level.
11. Applicable inspection standard
The LCD module shall meet the following inspection standard :
1
S-U-014 S-U-035
WARNING
Don’t use any materials which emit following gas from epoxy resin (amines’ hardener) and
silicone adhesive agent (dealcohol or deoxym) to prevent change polarizer color owing to gas.
