CostĪ ton of CRT TVs are pretty affordable, some costing less than $20! On the contrary, LED TVs can cost anywhere from a $100-300 to upward of 1,000+ depending on brand, size, condition and resolution. The environmental impact of manufacturing and transporting LEDs usually results in a net loss. However, making semiconductors and high-quality glass use vast amounts of energy. LEDs have no mercury, which is a little friendlier to the environment. Also, most recyclers either charge an exorbitant fee to handle them, or they refuse to deal with them at all. If they aren’t disposed of properly, they can cause pollution problems. Environmental concernsĬRTs have relatively high concentrations of phosphors and lead, making recycling and disposing of them challenging. Of course, you can always measure the total screen area to determine the display’s power use. It’s closer to 0.075 Watt per square inch if a user calibrates it to their taste. High-end LED TVs use about 0.1 Watt per square inch (at default settings), They also offer several power-saving features and greater efficiency. LEDs use even less power than CRTs and produce more reliable pictures. However, some HDTVs use more energy than certain CRTs because of their larger screens and greater area. Power useĬRT displays use a large amount of power for their size, with a TV needing about 0.3 Watt per square inch. This is just a brief explaination, check out this article that goes more in depth. The lights on the LCD panels increase the definition and brightness of the pictures and videos on the screen. Light-Emitting Diode (LED) monitors are LCD monitors with an LED backlight.
