CRTnäyttöjä

CRTnäyttöjä, also known as Cathode Ray Tube displays, were the standard type of television and computer monitor for many decades. They work by firing a beam of electrons from a cathode ray tube onto a phosphorescent screen. Magnets are used to direct this electron beam, which then illuminates tiny dots of red, green, and blue phosphor, creating the image you see. When these dots are illuminated in different intensities and patterns, they combine to form a full spectrum of colors. The electron beam scans across the screen line by line, very rapidly, to create the illusion of a moving image. The refresh rate, or how many times the image is redrawn per second, was a key factor in perceived image quality. CRTnäyttöjä were known for their deep black levels and fast response times, making them popular for gaming. However, they were also bulky, heavy, and consumed a significant amount of power. Over time, advancements in display technology, such as LCD and OLED, have largely replaced CRTs in most consumer electronics due to their thinner profiles, lower energy consumption, and higher resolutions. Despite being largely phased out, some niche applications and retro enthusiasts still utilize CRTnäyttöjä.
