A single IC or Single Chip could contain thousands or millions of transistors, resistors, capacitors and diodes. Additional components may also reside on it, all interconnected through a complex web of semiconductor wafers, silicon, copper and other materials. Size-wise, each component is small, usually microscopic. The resulting circuit, a monolithic chip, is also tiny -- often just enough to occupy a few square millimeters or centimeters of space. http://www.misuxin-en.com/integrated-circuit/single-chips/

A LED TV backlight for Lg is a liquid-crystal display that uses LEDs for backlighting instead of traditional cold cathode fluorescent (CCFL) backlighting. LED-backlit displays use the same TFT LCD (thin-film-transistor liquid-crystal display) technologies as CCFL-backlit LCDs, but offer a variety of advantages over them. While not an LED display, a television using such a combination of an LED backlight with an LCD panel is advertised as an LED TV by some manufacturers and suppliers. http://www.easternstarcn.com/led-tv-backlight/led-tv-backlight-for-lg/
