*3) Lamp frequency of inverter may produce interference with horizontal synchronous frequency,
and this may cause horizontal beat on the display. Therefore, please adjust lamp frequency, and
keep inverter as far from module as possible or use electronic shielding between inverter and
module to avoid the interference.
*4) Lamp life time is defined as the time either when the brightness becomes 50% of the initial
value, or when the starting lamp voltage does not meet the value specified in this table.

[Note]
These items are measured using CS1000(MINOLTA) for color coordinates, EZContrast(ELDIM) for
viewing angle and CS1000 or BM-5A(TOPCON) for others under the dark room condition (no
ambient light) after more than 30 minutes from turning on the lamp unless noted.
Condition: IL = 12.0 mArms, FL=43 kHz
Measurement method for luminance and color coordinates is as follows.
