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 your 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 your product design.

up duration. Otherwise the lamp could not be lighted on completely.
Note (3) The lamp frequency may produce interference with horizontal synchronous frequency from the
display, and this may cause 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.) as the time in which it continues to operate under the condition
