Unit Note

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 your 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 your product design.

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

Note (1) Lamp current is measured by utilizing AC current probe and its value is average by measuring

master and slave board.

Note (2) The lamp starting voltage V

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 and I

= 7.5~ 8.5mArms.

Note (5) The measurement condition of Max. value is based on 47" backlight unit under input voltage 24V,

average lamp current 8.3 mA and lighting 30 minutes later.

Note (1) The Dimming signal should be valid before backlight turns on by BLON signal. It is inhibited to

change the internal/external PWM signal during backlight turn on period.

Note (2) The power sequence and control signal timing are shown in the following figure. For a certain

reason, the inverter has a possibility to be damaged with wrong power sequence and control

signal timing.

Note (3) While system is turned ON or OFF, the power sequences must follow as below descriptions:

Turn ON sequence: VBL

Turn OFF sequence: BLOFF

Ш PWM signal Ш BLON

Ш PWM signal Ш VBL

Note (4) In order to avoid the abnormal phenomenon at dimming condition, skipped range of VIPWM

2.85~3.15V is suggested.
