When you visit a TV dealer, you may be given options like LCD, LED, QLED, and OLED. If you do not know the differences, chances are that you wouldn’t be able to choose. The most important factor to consider for buying a TV is the screen and panel technology. Through antiquated technologies like plasma and standard LCD no longer exist, the new QLED and OLED are quite confusing. An LED (Light Emitting Diode) is the most common choice that made TV slimmer and pictures brighter. It is more energy-efficient and an affordable option too. QLED (Quantum Dot) is a new screen technology that uses quantum dot semiconductors to produce color. Samsung introduced this technology, which makes picture quality brighter and colorful. This is more expensive. OLED (Organic LED) is considered the best screen technology available today, and the most expensive one. The technology-infused individual organic pixels emitting light while electric current passes through them.
