We break down the differences between the three main types of TV screen tech – and bring you some of the best models from each category.
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. Cancelled and now obsolete technologies are SED and FED.
UHD Phase A is a set of guidelines from the Ultra HD Forum for the distribution of SDR and HDR content using Full HD 1080p and 4K UHD resolutions. It requires a color depth of 10 bits per sample, a color gamut of Rec. 709 or Rec. 2020, a frame rate of up to 60 fps, a display resolution of 1080p or 2160p and either standard dynamic range (SDR ...
