The course discusses how different display technologies produce their light output by comparing the properties of: CRT, LCD, OLED, and DLP. We will examine the way in which the diverse technology determines fundamental display properties: the relationship between video input signal and output intensity for each primary; the chromaticity invariance of each primary; the primaries’ temporal independence and stability; spatial uniformity and spatial independence; the independence and interdependence between primaries; the ability to display black. Moreover, we will discuss how to set a display to a known state (display calibration) and show how to measure the relationship between the signal used to drive a display and the radiant output produced by each primary (optoelectronic transfer function), and how to model such a relationship (display characterisation). Furthermore, we will consider the display colour gamut, its output resolution and how this can affect the resulting dynamic range. Finally, we will present standard RGB spaces (sRGB and Adobe RGB) widely used in the display industry to compare the extent of the colour gamut across displays.
Benefits: Attendees will be able to:
Intended audience: Those who wish to understand the differences and implications of using modern display devices. Those who wish to learn how to calibrate, characterise and manage the light output of computer-controlled displays.
