According to ScreenTek, newer-model LED TVs are more beneficial than older LCD TVs, as LED TVs consume a lower amount of energy, generate less heat, have a longer lifespan and feature a brighter screen. LCD TVs are backlit with CCFL (cold cathode fluorescent lamp) lighting.Know More
ScreenTek adds that the difference between LED and LCD TVs is how they are lighted. LED TVs are LCD TVs. However, the newer models are backlit with a light-emitting diode rather than a cold cathode fluorescent lamp, or CCFL, like older LCD TVs.
ScreenTek states that the liquid crystal display of LCD TVs does not manufacture light by itself in order to illuminate an image. Therefore, a backlight is used in the form of an LED or CCFL. CCFLs are also used widely for laptop LCDs. The lighting consists of a fluorescent tube affixed to an inverter board that supplies electricity to the lamp. In some instances, the backlight features two tubes and two pairs of inverters, and is referenced by the acronym of 2-CCFL.
ScreenTek says that LEDs utilize an LED strip rather than a tube. According to the site, LED backlights do not require inverters. The technology is used in GPS devices and mobile phones. The utilization of LED backights in laptops is popular, as the lights are a more a cost-effective alternative.Learn more about Television & Video
Old televisions and other electronics should be recycled or donated at participating electronics retailers such as Best Buy or Staples, according to the EPA. If there is no retailer nearby that is participating in this program, E-Cycling Central recommends finding a private recycling company that accepts electronics from individuals.Full Answer >
LED televisions are more energy efficient than LCD televisions because the backlighting source in an LED demands less electricity. However, CNET claims that the difference probably doesn't translate to savings because the initial investment in an LED model is higher, and the energy savings can't recover the expense.Full Answer >

LED televisions do not inherently have superior resolution to LCD televisions. LED televisions are LCD displays that use light-emitting diodes to illuminate the display. While this lighting system has potential advantages over older methods of lighting LCD displays, the use of LEDs does not directly affect display resolution.Full Answer >
