Appendix E: Optical Characteristics – ventura 150 TFT

The following items were measured under stable conditions. The optical characteristics should be measured in a dark room or equivalent state.

* Measuring equipment:			TOPCON MB-5A: Contrast Ratio, Luminance of White, Viewing Angle
			TOPCON BM-7: Response time, Flicker
			Photo Research PR650: Colour Chromaticity
* Ta = 25± 2 0C,			VIN = +12Vm	fv= 60Hz.,		IL = 6.0mA
