Remark
Note1
Note 3
Note 1: There are total 6 LED serial in back light unit
Note 2: Optical performance should be evaluated at Ta=25only.
Note 3: 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.

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.
Vwhite: To be determined Vblack: To be determined.
Note 4: Definition of Response time
The response time is defined as the LCD optical switching time interval between “White” state and
“Black” state. Rise time (TON) is the time between photo detector output intensity changed from 90%
to 10%. And fall time (TOFF) is the time between photo detector output intensity changed from 10%
to 90%.
