Konsumentplasmaskärmar

Konsumentplasmaskärmar, or consumer plasma screens, are flat‑panel display devices that use plasma technology to create images. They were introduced in the 1990s as an alternative to cathode‑ray tube (CRT) televisions and were popular for their large screen sizes, high resolution, and wide viewing angles. Plasma displays generate images by energizing a mixture of inert gases—typically xenon and neon—between two layers of glass. The energized gas produces ultraviolet light, which strikes phosphor coatings to emit visible light, forming the picture.

Unlike liquid‑crystal displays (LCDs), plasma panels do not require backlighting. This allows for deeper blacks, higher contrast ratios, and more natural color reproduction, which contributed to their appeal in home‑cinema setups. However, plasma screens have higher power consumption and can suffer from phosphor degradation, leading to issues such as burn‑in or image retention when static images are displayed for extended periods.

During the 2000s, advancements in LCD, LED‑backlit LCD, and OLED technologies began to eclipse plasma displays. Manufacturers shifted focus to LCD due to lower costs, thinner profiles, and improved energy efficiency. Consequently, major plasma producers announced phase‑out plans, and new models have not been released for several years.

Environmental concerns surrounding plasma televisions include the disposal of heavy metals in phosphors and the higher energy consumption over the screen’s lifespan. Recycling programs in several countries now recover glass, metals, and components. Consumer plasma screens were widely marketed in the early 2000s but have since largely been replaced by newer display technologies.

The term "konsumentplasmaskärmar" is used primarily in Swedish contexts to describe these consumer‑grade plasma display products that were once a dominant form of large‑screen media consumption.
