Note (1) Temperature and relative humidity range is shown in the figure below.

(a) 90 %RH Max. (Ta Љ 40 ºC).

(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.

Value

Unit Note

(1)

Thermal management should be considered in final product design to prevent the surface temperature of

display area from being over 65 ºC. The range of operating temperature may degrade in case of

improper thermal management in final product design.

Note (3) 11 ms, half sine wave, 1 time for ± X, ± Y, ± Z.

Note (4) 10 ~ 200 Hz, 10 min, 1 time each X, Y, Z.

Note (5) At testing Vibration and Shock, the fixture in holding the module has to be hard and rigid enough so that

the module would not be twisted or bent by the fixture.

5.5 COLOR DATA INPUT ASSIGNMENT

The brightness of each primary color (red, green and blue) is based on the 8-bit gray scale data input for the color.

The higher the binary input, the brighter the color. The table below provides the assignment of the color versus

data input.

Note.

The supply voltage of the external system for the module input should follow the definition of Vcc.

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.

In case of VCC is in off level, please keep the level of input signals on the low or high impedance.

T4 should be measured after the module has been fully discharged between power off and on period.

Interface signal shall not be kept at high impedance when the power is on.

Note (2) Definition of Contrast Ratio (CR):

The contrast ratio can be calculated by the following expression.

Contrast Ratio (CR) = L255/L0

L255 : Luminance of gray level 255

L0 : 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 (7).

Note (3) Definition of Gray-to-Gray Switching Time:

www.panelook.com

Issue Date:Dec.25.2007

Model No.: V420H1-L09

Approval

The driving signal means the signal of luminance 0%, 20%, 40%, 60%, 80%, 100%.

Gray to gray average time means the average switching time of luminance 0%, 20%, 40%, 60%, 80%,

100% to each other.

Note (4) Definition of Luminance of White (LC, LAVE):

Measure the luminance of gray level 255 at center point and 5 points

LC = L (5), where L (X) is corresponding to the luminance of the point X at the figure in Note (7).

Note (5) Definition of Cross Talk (CT):

CT = | YB – YA | / YA u 100 (%)

Where:

YA = Luminance of measured location without gray level 0 pattern (cd/m2)

YB = Luminance of measured location with gray level 0 pattern (cd/m2)

8. PRECAUTIONS

8.1 ASSEMBLY AND HANDLING PRECAUTIONS

[ 1 ] Do not apply rough force such as bending or twisting to the module during assembly.

[ 2 ] It is recommended to assemble or to install a module into the user’s system in clean working areas. The

dust and oil may cause electrical short or worsen the polarizer.

[ 3 ] Do not apply pressure or impulse to the module to prevent the damage of LCD panel and Backlight.

[ 4 ] Always follow the correct power-on sequence when the LCD module is turned on. This can prevent the

damage and latch-up of the CMOS LSI chips.

[ 5 ] Do not plug in or pull out the I/F connector while the module is in operation.

[ 6 ] Do not disassemble the module.

[ 7 ] Use a soft dry cloth without chemicals for cleaning, because the surface of polarizer is very soft and easily

scratched.

[ 8 ] Moisture can easily penetrate into LCD module and may cause the damage during operation.

[ 9 ] When storing modules as spares for a long time, the following precaution is necessary.

[ 9.1 ] 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 35кat normal humidity without

condensation.

[ 9.2 ] The module shall be stored in dark place. Do not store the TFT-LCD module in direct sunlight or

fluorescent light.

[ 10 ] When ambient temperature is lower than 10ºC, the display quality might be reduced. For example, the

response time will become slow, and the starting voltage of CCFL will be higher than that of room

temperature.

8.2 SAFETY PRECAUTIONS

[ 1 ] The startup voltage of a Backlight is approximately 1000 Volts. It may cause an electrical shock while

assembling with the 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.

[ 3 ] After the module’s end of life, it is not harmful in case of normal operation and storage.
