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

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

improper thermal management in final product design.

should be detached from the horizontal synchronous frequency and its harmonics as far as possible.

Note (4) The life time of a lamp is defined as when the brightness is larger than 50% of its original value and the

effective discharge length is longer than 80% of its original length (Effective discharge length is defined

as an area that has equal to or more than 70% brightness compared to the brightness at the center point

of lamp.) as the time in which it continues to operate under the condition at Ta = 25 ±2к and IL =6.0~

7.0mArms.

Note (5) The power supply capacity should be higher than the total inverter power consumption PBL. Since the

pulse width modulation (PWM) mode was applied for backlight dimming, the driving current changed as

PWM duty on and off. The transient response of power supply should be considered for the changing

loading when inverter dimming.

Note (6) The measurement condition of Max. value is based on 42" backlight unit under input voltage 24V,

average lamp current 6.8 mA and lighting 30 minutes later.

5.6 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.

The driving signal means the signal of gray level 0, 63, 127, 191, and 255.

Gray to gray average time means the average switching time of gray level 0, 63,127,191,255 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)

Note (6) Measurement Setup:

The LCD module should be stabilized at given temperature for 1 hour to avoid abrupt temperature

change during measuring. In order to stabilize the luminance, the measurement should be executed after

lighting backlight for 1 hour in a windless room.

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.
