Photometric testing of a liquid crystal display

Liquid Crystal Displays (LCDs) were tested by photometric means using two techniques: the usual one-point measuring technique and, more detailed, two- hundred-point technique proposed by the authors. Inspection of the LC units was conducted while test images (white, RGB and chess patterned black and white) were displayed, to analyze distribution of luminance more precisely. Results of analysis are qualitatively compared to proposed lightning level standards and recommendations to prolong the lifespan of the LCD unit is given.
