13 / 27 page  – 13 – LCX038ART <Electro-optical Characteristics Measurement> • Measurement system I • Measurement system II Light Detector Measurement Equipment Optical fiber LCD panel Light receptor lens Drive Circuit Light Source Basic measurement conditions (1) Driving voltage HVDD = 13.5V, VVDD = 15.5V VVC = 7.5V, Vcom = 7.1V (2) Measurement temperature 25°C unless otherwise specified. (3) Measurement point One point in the center of the screen unless otherwise specified. (4) Measurement systems Two types of measurement systems are used as shown below. (5) Video input signal voltage (Vsig) Vsig = 7.5 ± VAC [V] (VAC = signal amplitude) Projection size: 101.6cm (40 in) Projection lens: F1.7 Light source: 120W UHP lamp Incidence illumination system: F#2.5 Polarzer: Side of incidence light-Polatechno's SHC-128U Side of output light-Polatechno's SKN-18243 LCD Projector Approx. 2000mm 1. Contrast Ratio Contrast Ratio (CR) is given by the following formula (1). CR = L (White) ... (1) L (Black) L (White): Surface luminance of the center of the screen at the input signal amplitude VAC = 0.5V. L (Black): Surface luminance of the center of the screen at VAC = 5.0V. Both luminosities are measured by System I. |
