LED LCD TVs are LCD televisions that use LED technology for backlighting, rather than traditional fluorescent lights that are found in conventional LCD TVs. The premise for using LED lighting is that conventional LCD televisions are unable to produce the depth required for a sharp black image. LEDs have been found to create this contrast and the color perception that TV viewers desire. Fluorescent lights also have a reduced range of colors they can produce, whereas the LED lights have a broader range and create a deeper color saturation.http://gadgetwise.blogs.nytimes.com/2009/06/11/whats-an-led-tv/

There are several television manufacturers that have begun using this technology including Samsung, Toshiba, LG and Sony.http://www.amazon.com/s/ref=amb_link_354026162_9?ie=UTF8&rh=n:172659,p_n_feature_three_browse-bin:2232445011&pf_rd_m=ATVPDKIKX0DER&pf_rd_s=left-2&pf_rd_r=0YGM5JTF9551KZPSKFEB&pf_rd_t=101&pf_rd_p=1276675022&pf_rd_i=1266092011#/ref=sr_st?qid=1286822246&rh=n%3A172282%2Cn%3A!493964%2Cn%3A1266092011%2Cn%3A172659%2Cp_n_feature_three_browse-bin%3A2232445011&sort=price In addition to using LED lighting, these televisions also provide users with the most advanced features such as Samsung's compatibility with the Samsung LinkStick for wireless Internet connectivity or VIA, the online application feature for Vizio televisions.http://www.samsung.com/us/video/tvs-accessories/WIS09ABGNX/XAA Depending upon the screen size, they may be available with a resolution of 720p or 1080p, and each are HD ready. http://www.amazon.com/s/ref=amb_link_354026162_9?ie=UTF8&rh=n:172659,p_n_feature_three_browse-bin:2232445011&pf_rd_m=ATVPDKIKX0DER&pf_rd_s=left-2&pf_rd_r=0YGM5JTF9551KZPSKFEB&pf_rd_t=101&pf_rd_p=1276675022&pf_rd_i=1266092011#/ref=sr_st?qid=1286822246&rh=n%3A172282%2Cn%3A!493964%2Cn%3A1266092011%2Cn%3A172659%2Cp_n_feature_three_browse-bin%3A2232445011&sort=priceThose featuring local dimming automatically change the LED lighting to accommodate the current image by reducing lighting in specific areas of the screen. For connecting to other devices, LED LCD televisions also have HDMI and USB inputs for premium connections and multimedia capabilities.

The technology of manufacturing LCD televisions has been built upon the basic structure of a backlight shown through a liquid crystal display. With LED backlighting, there are several options that can be used such as a conventional white backlight or RGB technology as seen in Sony products. To better understand how these components interact, this video illustrates how LCD and LED technology are combined to produce a higher quality television image.
