A widespread practical application is using quantum dot enhancement film (QDEF) layer to improve the LED backlighting in LCD TVs.Light from a blue LED backlight is converted by QDs to relatively pure red and green, so that this combination of blue, green and red light incurs less blue-green crosstalk and light absorption in the color filters after the LCD screen, thereby increasing useful ...
The projector uses a bright beam of light and a lens system to project the image to a much larger size.

[ 73 ] In 1997, Philips introduced at CES and CeBIT the first large (42-inch or 110-centimetre) commercially available flat-panel TV, using Fujitsu plasma displays.
Laser color television (laser TV), or laser color video display, is a type of television that utilizes two or more individually modulated optical (laser) rays of different colors to produce a combined spot that is scanned and projected across the image plane by a polygon-mirror system or less effectively by optoelectronic means to produce a color-television display.
In May 2011, TCL launched the China Smart Multimedia Terminal Technology Association in partnership with Hisense Electric Co. and Sichuan Changhong Electric Co., with the aim of helping to establish industry standards for smart televisions. In January 2013, TCL bought the naming rights for Grauman's Chinese Theatre for $5 million. [20]
