Comparison of CRT, LCD, plasma, and OLED displays covers the technical and performance differences between major display technologies. While Cathode Ray Tube (CRT) and Plasma (PDP) were the dominant standards of the late 20th and early 21st centuries, they have been largely superseded by Liquid Crystal Displays (LCD) and Organic Light-Emitting Diodes (OLED). As of 2026, the market is defined by advanced sub-types including Mini-LED backlighting for LCDs, QD-OLED (Quantum Dot OLED), and the emergence of MicroLED as a high-performance inorganic emissive alternative. Only descriptions about CRT, LCD (mini LEDs), Plasma and OLED displays are given in this article.
Combines a blue OLED light source with a Quantum Dot conversion layer. This eliminates the need for colour filters, resulting in significantly higher colour volume and vibrancy compared to traditional White OLED (WOLED).
A structure that stacks two or more organic light-emitting layers vertically. This design doubles brightness and significantly extends the lifespan (up to 60% longer) of the display, making it ideal for tablets, laptops, and automotive use.
A self-emissive technology using non-organic microscopic LEDs. It offers the infinite contrast of OLED but with much higher durability, virtually no burn-in risk, and peak brightness can exceed 10,000 nits.
