Note1: The LED driving condition is defined for each LED module (3 LED Serial, 6 LED Parallel).For
each LED: IF (1/6) =20mA, VF (1/3) =3.3V.
Note2: Under LCM operating, the stable forward current should be inputted. And forward voltage is
for reference only.
Note3: IF is defined for one channel LED. Optical performance should be evaluated at Ta=25only
If LED is driven by high current, high ambient temperature & humidity condition. The life time of LED
will be reduced. Operating life means brightness goes down to 50% initial brightness. Typical
operating life time is estimated data.

Model No.TM070DVHG01
Note 1: Definition of optical measurement system.
The optical characteristics should be measured in dark room. After 5 Minutes operation, the optical
properties are measured at the center point of the LCD screen. All input terminals LCD panel must
be ground when measuring the center area of the panel.

Note 2: Definition of viewing angle range and measurement system.
viewing angle is measured at the center point of the LCD by CONOSCOPE(ergo-80)
Note 3: Definition of contrast ratio
―White state ―: The state is that the LCD should drive by Vwhite.
―Black state‖: The state is that the LCD should drive by Vblack.
