Note 7-7
The kick-off voltage is specified under the condition in just putting the backlight on the LCD module.
(the backlight cable is not unbent)
The kick-off voltage depends on way to lead the cable between inverter and backlight.
Caution
Please use the inverter which has the one of the sine wave. With regards to the inverter, it should be
negative / positive wave symmetry and the spike wave should not be occurred.

(10) Mechanical characteristics
10-1) External appearance
Do not exist extreme defects. (See Fig. 1)
10-2) Panel toughness
The panel shall not be broken, when 19N is pressed on the center of the panel by a smooth sphere
having 15 mm diameter.
Caution: In spite of very soft toughness, if, in the long-term, add pressure on the active area, it is
possible to occur the functional damage.
(11) Display quality
The display quality of the color TFT-LCD module shall be in compliance with the
Incoming Inspection Standards for TFT-LCD.
(12) Handling instructions
12-1) 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 0.5N m 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.
d) Dont pull a CCFT lead line with the power beyond 10N. It has the possibility of the breakage
in the lamp, the connection part of the lead line, and so on.
12-2) Precautions in mounting
Polarizer which is made of soft material and susceptible to flaw must be handled carefully.
Protection sheet is applied on the surface to protect it against scratches and dirties.
It is recommended to remove the protection sheet immediately before the use, taking care of
static electricity.
Precautions in removing the protection sheet
A) Working environment
When the protection sheet is removed 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 1M 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 protection sheet part near discharging blower
so as to protect polarizer against flaw.
c) Remove the protection sheet, pulling adhesive tape slowly to your side.
d) On removing the protection sheet, pass the module to the next work process
to prevent the module to get dust.
