(b) Wet-bulb temperature should be 39 ºC Max. (Ta > 40 ºC).
(c) No condensation.
Note (2) The maximum operating temperature is based on the test condition that the surface temperature of
display area is less than or equal to 65 ºC with LCD module alone in a temperature controlled chamber.
Thermal management should be considered in final product design to prevent the surface temperature of
Unit Note
display area from being over 65 ºC. The range of operating temperature may degrade in case of
improper thermal management in final product design.

2.2 PACKAGE STORAGE
When storing modules as spares for a long time, the following precaution is necessary.
(a) Do not leave the module in high temperature, and high humidity for a long time, It is highly recommended to
store the module with temperature from 0 to 35 at normal humidity without condensation.℃
(b) The module shall be stroed in dark place. Do not store the TFT-LCD module in direct sunlight or fluorescent
light.

Note (1) The supply voltage of the external system for the module input should follow the definition of Vcc.
Note (2) Apply the lamp voltage within the LCD operation range. When the backlight turns on before the LCD
operation or the LCD turns off before the backlight turns off, the display may momentarily become
abnormal screen.
Note (3) In case of Vcc is in off level, please keep the level of input signals on the low or high impedance. If
T2<0,that maybe cause electrical overstress failure.
Note (4) T4 should be measured after the module has been fully discharged between power off and on period.
Note (5) Interface signal shall not be kept at high impedance when the power is on.

Note (0) Light source is the standard light source ”C” which is defined by CIE and driving voltage are based on
suitable gamma voltages. The calculating method is as following:
1. Measure Module’s and BLU’s spectrum at center point. White is without signal input and R,G,B are
with signal input. BLU (for V420H2-L06) is supplied by CMO.
2. Measure Module’s and BLU’s spectrum at center point. W, R,G, B are with signal input. BLU (for
V420H2-L06) is supplied by CMO.
3. Calculate cell’s spectrum.
4. Calculate cell’s chromaticity by using the spectrum of standard light source “C”.

Viewing angles are measured by Autronic Conoscope Cono-80. ( or Eldim EZ-Contrast 160R )
PRODUCT SPECIFICATION
Note (3) Definition of Contrast Ratio (CR):
The contrast ratio can be calculated by the following expression.
Contrast Ratio (CR) =
L255: Luminance of gray level 255
L 0: Luminance of gray level 0
CR = CR (5), where CR (X) is corresponding to the Contrast Ratio of the point X at the figure in Note (5).

The driving signal means the signal of gray level 0, 124, 252, 380, 508, 636, 764, 892 and 1023.
Gray to gray average time means the average switching time of gray level 0, 124, 252, 380, 508, 636,
764, 892 and 1023 to each other.

Note (5) Definition of White Variation (δW):
Measure the luminance of gray level 255 at 5 points
δW = Maximum [L (1), L (2), L (3), L (4), L (5)] / Minimum [L (1), L (2), L (3), L (4), L (5)]

8. PRECAUTIONS
8.1 ASSEMBLY AND HANDLING PRECAUTIONS
[ 1 ] Do not apply rough force such as bending or twisting to the product during assembly.
[ 2 ] To assemble backlight or install module into user’s system can be only in clean working areas. The dust and
oil may cause electrical short or worsen the polarizer.
[ 3 ] It’s not permitted to have pressure or impulse on the module because the LCD panel will be damaged.
[ 4 ] Always follow the correct power sequence when the product is connecting and operating. This can prevent
damage to the CMOS LSI chips during latch-up.
[ 5 ] Do not pull the I/F connector in or out while the module is operating.
[ 6 ] Use a soft dry cloth without chemicals for cleaning, because the surface of polarizer is very soft and easily
scratched.
[ 7 ] It is dangerous that moisture come into or contacted the product, because moisture may damage the
product when it is operating.
[ 8 ] High temperature or humidity may reduce the performance of module. Please store this product within the
specified storage conditions.
[ 9 ] When ambient temperature is lower than 10ºC may reduce the display quality. For example, the response
time will become slowly.
8.2 SAFETY PRECAUTIONS
[ 1 ] 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.
[ 2 ] After the product’s end of life, it is not harmful in case of normal operation and storage.
