Depends on system |
Major technologies are CRT, LCD and its derivatives (Quantum dot display, LED backlit LCD, WLCD, OLCD), Plasma, and OLED and its derivatives (Transparent OLED, PMOLED, AMOLED). An emerging technology is Micro LED and cancelled and now obsolete technologies are SED and FED.
Different display technologies have vastly different temporal characteristics, leading to perceptual differences for motion, flicker, etc.
The figure shows a sketch of how different technologies present a single white/grey frame. Time and intensity is not to scale. Notice that some have a fixed intensity, while the illuminated period is variable. This is a kind of pulse-width modulation. Others can vary the actual intensity in response to the input signal.
Researchers announced a display that uses silicon metasurface pixels that do not require polarized light and require half the energy. It employs a transparent conductive oxide as a heater that can quickly change the pixels. The pixels are 100 times thinner than liquid crystal. Response times are under 1 millisecond. They claim that the metasurface array could replace the liquid crystal layer in today's displays, eliminating the need for production technology.[25]
