3.0OPTICALCHARACTERISTICS
TEST CONDITIONS
Optical characteristics are determined after the unit has been ‘ON’ and stable for approximately 45
minutes in a dark environment at 25. The values specified are at an approximate distance 50cm ℃from
the LCD surface at a viewing angle of Φand θequal to 0°.

Note:
1. Contrast Ratio(CR) is defined mathematically as :Surface Luminance at all white pixels CR
= Surface Luminance at all black pixels. It is measured at center 1-point.
2. Surface luminance are determined after the unit has been ‘ON’ and 1Hourafterlighting the
backlight in a dark environment at 25±2°C. Surface luminance is the luminance value at
center 1-point across the LCD surface 50cm from the surface with all pixels displaying white.
For more information see the FIG. 2.
3. The output signals of photo detector are measured when the input signals are changed for
“White” to “Black” (falling time) and form “Black” to “White” (rising time), respectively. The
response time Interval is between 10% and 90% of amplitudes, see the FIG.3.
4. Viewing angle is the angle at which the contrast ratio is greater than 10. The angles are
determined or the horizontal or x axis and the vertical or y axis with respect to the z axis
which is normal to the LCD module surface. For more information, seethe FIG. 4.

Response time is defined as the following figure and shall be measured by switching the input
signal for “White” and “Black”.

5.0PRECAUTIONS
HANDLING PRECAUTIONS
(1) The module should be assembled into the system firmly by using every mounting hole.
Be careful not to twist or bend the module.
(2) While assembling or installing modules, it can only be in the clean area. The dust and oil
may cause electrical short or damage the polarizer.
(3) Use fingerstalls or soft gloves in order to keep display clean during the incoming
inspection and assembly process.
(4) Do not press or scratch the surface harder than a HB pencil lead on the panel
because the polarizer is very soft and easily scratched.
(5) If the surface of the polarizer is dirty, please clean it by some absorbent cotton or soft
cloth. Do not use Ketone type materials (ex. Acetone), Ethyl alcohol, Toluene, Ethyl acid
or Methyl chloride. It might permanently damage the polarizer due to chemical reaction.
(6) Wipe off water droplets or oil immediately. Staining and discoloration may occur if
they left on panel for a long time.
(7) If the liquid crystal material leaks from the panel, it should be kept away from the eyes or
mouth. In case of contacting with hands, legs or clothes, it must be washed away
thoroughly with soap.
(8) Protect the module from static electricity, it may cause damage to the C-MOS Gate Array
IC.
(9) Do not disassemble the module.
(10) Do not pull or fold the lamp wire.
(11) Pins of I/F connector should not be touched directly with bare hands.
STORAGE PRECAUTIONS
(1) High temperature or humidity may reduce the performance of module. Please store
LCD module within the specified storage conditions.
(2) It is dangerous that moisture come into or contacted the LCD module, because the
moisture may damage LCD module when it is operating.
(3) It may reduce the display quality if the ambient temperature is lower than 10 ºC. For
example, the response time will become slowly, and the starting voltage of lamp will be
higher than the room temperature.
OPERATION PRECAUTIONS
(1) Do not pull the I/F connector in or out while the module is operating.
(2) Always follow the correct power on/off sequence when LCD module is connecting and
operating. This can prevent the CMOS LSI chips from damage during latch-up.
