What is LED backlight LCD TV?
LCD TV LED backlight LCD is a flat -screen television in which the front liquid crystal display panel (LCD) is illuminated by a series of Dios emitting light (LED). TV for flat screen and computer monitors require a certain form of rear lighting, so the image displayed on the LCD panel will be visible to the viewer. Early LCD TVs and monitors used other types of lighting, often high -performance fluorescent lamps. However, LED LESTRIGHT LCD TV Screens have several advantages over earlier versions of flat screen technology, including energy consumption, brightness and lifetime.
LCD monitors and TVs work by filtering white light from the background source, allowing only the colors needed to create the image on the screen and be visible. This process is not very efficient and most of the light produced in LCD TV is filtered, leading to high energy consumption. LED LED Shillight LCD TV is more energy efficient than before Flat Scrtelevant EENE Each LED is responsible for lighting only very small parts of the screen and each LED must generate light only if this screen area must show the image and only at the brightness level necessary for the displayed image. This characteristics of LED backlit LCD TVs reduce the formation of waste light and heat.
Another advantage for high quality LED LCD TV is their longer average life. LEDs are very simple and durable products if they are manufactured correctly and can provide years of reliable services. TV for flat screens backlit by high -performance fluorescent bulbs are susceptible to failure related to their lighting systems. LEDs, on the other hand, if they are made for a reasonably high standard, it is less likely that LCD TV backlight will fail in front of other elements. Individual LEDs FinallyRY on LCD TV screen, where pixels are no longer illuminated.
More advanced technologies similar to the principles to LCD TV LED backlight. Organic LED technology combines two key components with a flat screen. In such devices, the LCD panel that creates a picture for the display can also directly transmit light. This is a significant advantage, because there may not be unnecessary energy that creates light in parts of a visible spectrum that will be filtered through the imaging panel or in the lighting of the darkened screen areas.
