What is an LED HDTV?
An LED backlit LCD TV is used an LCD TV that uses LED-backlit display, instead of the CCFLs in conventional LCD TVs. There is no real LED display but mean "LED TV" by some vendors. The use of LED-backlit display has a dramatic impact, making a thin Panel, less power consumption and heat dissipation and a brighter display with better contrast levels.
The LEDs can come in three forms:
Dynamic RGB LEDs, which are positioned behind the PanelWhite edge LEDs-around the edge of the screen with a special distribution panel evenly behind the screen (most commonly) to spread the light a full array of LEDS, which are arranged behind the screen, but are individually positioned not dimming or lighteningLED backlighting techniques:
A LED-backlit TV: Dynamic RGB LEDs enables occur this backlight dimming method in locally specific areas of darkness on the screen. This may be true black, white and PRs at much higher dynamic contrast ratio, at the expense of less detail in small bright objects on a dark background, such as a star field display.
Edge LEDs: This method of backlighting allows for LED-backlit TVs to be extremely thin. The light is produced widely across the screen by a special panel a uniform color range across the screen.
Full array LEDs: LED backlight technology and how many brands offer a number of advantages over CCFL LCD TVs reduces energy consumption, better contrast and brightness, larger color palette, faster response to changes in scene and a capacity to more precisely to render offer the means to an image.
Differences between LED-backlit and CCFL-backlit LCD displays
LED backlit LCD TVs differ from conventional CCFL-backlit of LCD TVs in the following:
Produce images with a higher dynamic contrast. With edge-LED lighting they can be extremely slim. Models on the market may be about an inch thick. Provide a larger color space, especially if RGB-LED-backlit display is used.Less environmental pollution disposal. Typically 20-30% lower power consumption.
