Note (2) The lamp starting voltage VS should be applied to the lamp for more than 1 second after startup.
Otherwise the lamp may not be turned on.
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 2к

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

5.7 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 (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.

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) 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.
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.
