Dual mode type [NTSC (M) and PAL(BG) standards]  
MBK-PAL which enables the 240-scanning lines panel to display a picture with virtually 274-  
scanning lines.  
Reduced reflection as a result of low reflectance black matrix and an antiglare (AG) and anti-  
reflection (R) polarizer being adopted.  
A thin, lightweight and compact  
Effective area/Outline area= 82% Thickness=12.5 mm Mass=205g  
Multi scene display which is able to display high-quality color image in all lighting condition  
Through the use of TN-normally white mode, an image with highly natural color reproduction  
is realized.  
It is possible to reverse the display direction (rightleft and updown).

Note2-2】  
Note2-3】  
This terminal is to reverse the polarity of common electrode driving signal (COM).  
This terminal is to reverse the polarity of video signal. Use of a dedicated video  
signal polarity reversing IC should be used. Recommended interface ICs to be  
reversed the polarity of video signal are the IR3Y26A (analog RGB input type)  
and IR3Y29BM (composite video type) manufactured by Sharp.  
This terminal is to be input the video signal which whose polarity is reversed in  
compliance with the FRPV inverse timing signal.  
Note2-4】  
Note2-5】  
This terminal is to be input the common electrode driving signal (COM) whose  
polarity is reversed in compliance with the FRPV inverse timing signal.  
Brightness is adjusted through a change of the COM signal amplitude, and the  
center position of the COM input signal (VCDC) is adjusted, maximum contrast  
for a module's display screen should be achieved.

Note2-12】  
Note2-13】  
PWM signal is used for the PWM dimming frequency and it is possible to  
control the PWM signal dimming by combining both HSY and PWM signal. But,  
please use this PWM signal just in case of inputting standard NTSC or PAL  
signal. See Fig.4-I)  
VMSW = “Hi”: Vertical 240 line display  
VMSW = ‘Lo”: Vertical 234 line display  
Masking signal for upper 1 line and bottom 5 line is output with VCS  
signal.  
When CLKC="Hi", this terminal outputs low level.  
When CLKC="Lo", this terminal will be external clock input terminal.  
This signal should correspond to sampling timing of the horizontal direction  
image. NTP, MODS, MODW, and MODN should be "Hi" when CLKC="Lo".  
Display mode settings are shown in Table 3.  
Note2-14】  
Note2-15】  
In case of normal mode (MODS="Hi", MODW="Lo", MODN="Hi"), it is possible  
to get an excellent display by masking of video signal based on the VCS output  
signal. The video signal is masked when VCS is "Hi" (the two edges of the  
screen). (In case of black masking display, it is possible to easily get the  
normal screen (full frame) by inputting the VCS signal at the system switching  
terminal of the video interface IC, inputting the field signal into another video  
input and inputting a signal for black into the other video input.  
And also, in case of vertical 234 lines, the masking signal of upper 1 line and  
bottom 5 lines is output regardless of display mode.  
In case of the other condition except above, the output of VCS becomes “Lo”.  
In case of the module test mode, the test signal is output.

4:3 signal Fig.3-2  
4:3 signal Fig.3-3  
A 4:3 video signal is displayed with less  
feeling of incongruity than that in the full  
screen mode. Since the video horizontal  
sampling frequency is modulated in the  
horizontal direction, the degree of perfect  
roundness in the center of the screen is  
improved over that of the full screen mode.  
When displaying a 4:3 video signal, the  
displayed image is slightly less than  
perfectly round and the horizontal retrace  
line period is displayed at the two edges of

the screen.  
With respect to the video  
horizontal sampling frequency, the center  
portion of the screen is slightly lower and the  
two edges become slightly higher. With  
respect to the horizontal retrace line period,  
a far better display is achieved than that of  
masking of the video signal by the VCS  
signal timing.

(10) Display quality  
The display quality of the color TFT-LCD module shall be in compliance with the  
Delivery Inspection Standard.  
(11) Handling instructions  
11-1) Mounting of module  
The TFT-LCD module is designed to be mounted on equipment using the mounting tabs  
in the four corners of the module at the rear side.  
On mounting the module, as the M2.6 tapping screw fastening torque is 0.3 through  
0. 5Nm(7mm length) is recommended, be sure to fix the module on the same plane,  
taking care not to wrap or twist the module.  
Don't reach the pressure of touch-switches of the set side to a module directly, because  
images may be disturbed.  
Please power off the module when you connect the input/output connector.  
Please connect the metallic shielding cases of the module and the ground pattern  
of the inverter circuit surely. If that connection is not perfect, there may be  
a possibility that the following problems happen.  
a). The noise from the backlight unit will increase.  
b). The output from inverter circuit will be unstable. Then, there may be a possibility that  
some problems happen.  
c). In some cases, a part of module will heat.  
11-2) Precautions in mounting  
Polarizer which is made of soft material and susceptible to flaw must be handled  
carefully. Protective film (Laminator) is applied on the surface to protect it  
against scratches and dirts. It is recommended to peel off the laminator immediatery  
before the use, taking care of static electricity.  
Precautions in peeling off the laminator  
A) Working environment  
When the laminator is peeled off, static electricity may cause dust to stick  
to the polarizer surface. To avoid this, the following working environment  
is desirable.  
a) Floor:Conductive treatment of 1MΩ or more on the tile  
(conductive mat or conductive paint on the tile)  
b) Clean room free form dust and with an adhesive mat on the doorway  
c) Advisable humidity:50%70%  
Advisable temperature:15℃~27℃  
d) Workers shall wear conductive shoes, conductive work clothes, conductive  
gloves and an earth band.  
B) Working procedures  
a) Direct the wind of discharging blower somewhat downward to ensure that  
module is blown sufficiently. Keep the distance between module and  
discharging blower within 20 cm.  
b) Attach adhesive tape to the laminator part near discharging blower  
so as to protect polarizer against flaw.  
c) Peel off laminator, pulling adhesive tape slowly to your side taking 5  
or more second.  
d) On peeling off the laminator, pass the module to the next work process  
to prevent the module to get dust.  
LCY0013121

Adhesive tape  
less than 20cm  
backlight cable  
e) Method of removing dust from polarizer  
Blow off dust with N2 blower for which static electricity preventive  
measure has been taken. Ionized air gun (Hugle Electronics Co.) is  
recommended.  
Since polarizer is vulnerable, wiping should be avoided.  
But when the panel has stain or grease, we recommend to use adhesive tape  
to softly remove them from the panel.  
When metal part of the TFT-LCD module (shielding lid and rear case) is soiled,  
wipe it with soft dry cloth. For stubborn dirts, wipe the part, breathing on it.  
Wipe off water drop or finger grease immediately. Long contact with water may cause  
discoloration or spots.  
TFT-LCD module uses glass which breaks or cracks easily if dropped or bumped on  
hard surface. Handle with care.  
Since CMOS LSI is used in this module, take care of static electricity and  
earth your body when handling.  
11-3) Precautions in adjusting module  
Adjusting volumes on the rear face of the module have been set optimally before  
shipment. Therefore, do not change any adjusted values. If adjusted values are  
changed, the specifications described here may not be satisfied.  
11-4) Caution of product design  
The LCD module shall be protected against water salt-water by the  
waterproof cover.  
Please take measures to interferential radiation from module, to do not interfere  
surrounding appliances.  
11-5) Others  
Do not expose the module to direct sunlight or intensive ultraviolet rays for  
many hours; liquid crystal is deteriorated by ultraviolet rays.  
Store the module at a temperature near the room temperature. At lower than  
the rated storage temperature, liquid crystal solidifies, causing the panel to be  
damaged. At higher than the rated storage temperature, liquid crystal turns into  
isotropic liquid and may not recover.  
The voltage of beginning electric discharge may over the normal voltage because of  
leakage current from approach conductor by to draw lump read lead line around.  
If LCD panel breaks, there may be a possibility that the liquid crystal escapes  
from the panel. Since the liquid crystal is injurious, do not put it into the eyes  
or mouth. When liquid crystal sticks to hands, feet or clothes, wash it out  
immediately with soap.  
Observe all other precautionary requirements in handling general electronic  
components.

Adjusting Method of Optimum Common electrode DC Bias Voltage  
To obtain optimum DC bias Voltage of common electrode driving signal, photo-electric  
devices are very effective, and the accuracy is within 0.1V. (In visual examination method, the  
accuracy is about 0.5V because of the difference among individuals.)  
To obtain optimum common electrode DC bias voltage, there is a measurement method as  
follows:  
Measurement of flicker method  
DC bias voltage is adjusted so as to minimize NTSC: 60Hz(30Hz)/PAL: 50Hz(25Hz) flicker.
