Display technology refers to the various methods and devices used to present visual information, such as images and videos, to users. It encompasses a wide range of technologies and formats, including cathode ray tubes (CRT), liquid crystal displays (LCD), light-emitting diodes (LED), organic light-emitting diodes (OLED), and more recent advancements like microLED and quantum dot displays. Each type of display technology has distinct characteristics in terms of color accuracy, brightness, contrast ratio, energy efficiency, response time, and viewing angles. Display technology is crucial in devices such as televisions, computer monitors, smartphones, and tablets, and it plays a vital role in how we perceive visuals in various applications, from entertainment to professional work. As technology continues to evolve, displays are becoming thinner, lighter, and capable of higher resolutions, enhancing the overall viewing experience.
