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 60 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 60 ºC. The range of operating temperature may degrade in case of

improper thermal management in final product design.

Note (1) Lamp current is measured by utilizing high frequency current meters as shown below:
Note (2) The lamp starting voltage V

should be applied to the lamp for more than 1 second after startup.

S

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 dischar ge le ngth is long er th an 80% of its origi nal length (Eff ective di sc harge leng th is
defined as an area that has equal to or more than 70% brightness compared to the brightness at
the center point of lam p.) as the time in which it contin ues to op er ate u nder t he c o ndit io n at Ta = 25

Note ( 5) The power s upply capacity should be hi gher than the total invert er power consum ption P

= 6.0~ 7.0mArms.

L

. Since

BL

the pulse width modulation (PWM) mode was applied for backlight dimming, the driving current
changed as PW M duty on and off. The transient response of power sup ply should be considere d
for the changing loading when inverter dimming.
