Abstract: A method of calibrating a flat panel display, comprising the steps of: providing a flat panel display, calibrating the display to establish desired chromaticity and/or luminance for one or more colors of interest at a first reference angle, measuring the chromaticity and/or luminance data for at least one color of interest at a minimum of one additional reference angle distinct from the first reference angle, and selecting a target calibration angle in response to the measured data and calibrating the display to establish desired chromaticity and/or luminance for colors of interest at the selected target calibration angle. The target calibration angle may be selected to deliver optimal display performance as a function of one or more desired viewing angles. These viewing angles can be in the tip direction, turn direction or in a direction that is some combination of tip and turn.

Abstract: An OLED device having green emitting regions disposed over a substrate, and wherein each green emitting region includes one or more light-emitting layer(s), a reflector and a semitransparent reflector respectively disposed on opposite sides of the light-emitting layer(s) and arranged to resonate light produced by such layers such that the light has a substantial green spectral component, and a yellow color filter element disposed in relationship to each green emitting region to produce green light.
