Advanced picture quality evaluation by measurements and visual testing
When a tv-set is evaluated for Germany´s well-known video-magazine it has to go through hundreds of measurements and comparism tasks with special testpatterns. Over the past 20 years, as technology went from the picture tube to UHD-HDR-OLED, the testing procedures got enhanced in a parallel manner. Not only standard parameters like color reproduction, sharpness and luminance have to be checked, also display effects like response time, dimming artefacts, uniformity, banding, clouding, quantisation, power limitations, black performance, EOTF-variations, scaling, cleaning or motion picture quality have to be evaluated. We test not the pure display, but a combined system of input electronics, video-processing, power supply, backlight and panel. And these components influence each other, especially in the new challenge of HDR with WCG. To go along with the technical TV-evolution new testing procedures and patterns are developed nearly every month.
