from the display, and this may cause line flow on the display. In order to avoid
interference the lamp frequency should be detached from the horizontal synchronous

of the DC-AC inverter for the lamp. All the parameters of an inverter should be
designed with care so as not to produce too much current leakage from high-voltage
output of the inverter. When designing or ordering the inverter, please make sure that
a poor lighting caused by the mismatch of the backlight and the inverter (miss-lighting,
flicker, etc.) never occurs. When the above situation is confirmed, the module should
be operated in the same manners as it is installed in your instrument.

5. OPTICAL SPECIFICATIONS
The following optical specifications shall be measured in a dark room or equivalent state
(ambient luminance ≤1 lux, and at room temperature). The measurement must be taken after
backlight warming up for 20 minutes. The operation temperature is 25°C ± 2°C. The
measurement method is shown in Note 1.

Note(4) Definition of Contrast Ratio (CR):
The contrast ratio can be calculated by the following expression.
Contrast Ratio (CR) = L63 / L0
L63 : Luminance on the white raster (gray level 63)

6. MECHNICAL DRAWING
Please refer to the attached drawings.
7. PRECAUTION
7. 1 ASSEMBLY AND HANDLING PRECAUTION
(1) Do not apply rough force such as bending or twisting to the module during assembly.
(2) To assembly and install module into user’s system are only in clean working areas. The
Dust and oil may cause an electrical short or worsen the polarizer.
(3) It’s not permitted to pressure or impulse the module because the LCD panel and backlight,
(4) Always follow the correct power sequence when user connects and operates the LCD
module to prevent damage to the CMOS LSI chips during latchup.
(5) Do not pull the I/F connectors in or out while the module is operation.
(6) Do not disassembly the module.
(7) Use a soft dry cloth without chemicals for cleaning, because the surface of polarizer is
very
soft and easily scratched.
(8) Any moisture come into contact with the LCD module is dangerous because LCD
modules is turned on with moisture on its surface may cause it damage.
(9) The high temperature or humidity may reduce the performance of module, to store LCD
module within the specified storage condition.
(10) The ambient temperature is lower than 10ºC may reduce the display quality, for example,
response time become slowly, the starting voltage of CCFL is higher than room
temperature.
(11)The mounting screw method is recommended in Figure 6.1.

7.2 SAFTY PRECAUTION
(1) The startup voltage of backlight is approximately 1000 Volts. It may cause electrical shock
during assembly with inverter. Do not disassemble the module or insert anything into the
backlight unit.
(2) If the liquid crystal material leaks from the panel, it should be kept away from the eyes or
mouth. In case of contact with hands, skin or clothes, it has to be washed away
thoroughly with soap.
