The test of Optical specifications shall be measured in a dark room (ambient luminance ≤ 1 lux and
temperature = 25±2℃) with the equipment of Luminance meter system (Goniometer system and TOPCON
BM-5) and test unit shall be located at an approximate distance 50cm from the LCD surface at a viewing
angle of θ and Φ equal to 0°. We refer to θ Ø=0 (=θ 3 ) as the 3 o’clock direction (the “right”), θ Ø=90 (= θ 12 ) as
the 12 o’clock direction (“upward”), θ Ø=180 (= θ 9 ) as the 9 o’clock direction (“left”) and θ Ø=270 (= θ 6 ) as the 6
o’clock direction (“bottom”). While scanning θ and/or Ø, the center of the measuring spot on the Display
surface shall stay fixed. The measurement shall be executed after 30 minutes warm-up period. VDD shall be
5.0V +/-10% at 25°C. Optimum viewing angle direction is 6 ’clock.
