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

(b)The module shall be stored in dark place. Do not store the TFT-LCD module in direct sunlight or

fluorescent light.

Note (3) The lamp frequency may produce interference with horizontal synchronous frequency of the display

input signals, and it may result in line flow on the display. In order to avoid interference, the lamp

frequency 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

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 31.5" backlight unit under input voltage 24V,

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 color

versus data input.

Power ON/OFF Sequence

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.

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.

10. PRECAUTIONS

10.1 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) High temperature or humidity may deteriorate the performance of LCD module. Please store LCD

modules in the specified storage conditions.

(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.

10.2 SAFETY PRECAUTIONS

(1) The startup voltage of a backlight is over 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.
