Development of Liquid Crystal Display with RGB Laser Backlight

Self-Assembled and Wavelength-Tunable Quantum Dot Whispering-Gallery-Mode Lasers for Backlight Displays

“…Laser displays have attracted intense interest because they are considered to be the next generation of display technology. − Apart from the pixelated laser array method, ,− white laser light enabled by integrating RGB lasers is another approach to laser displays. , Moreover, the integrated white laser as the backlight source is also compatible with conventional liquid crystal display (LCD) technology. − However, although many monochromatic miniaturized RGB lasers fabricated from inorganic semiconductors, − organic molecules, − or metal halide perovskites − have been reported, compactly integrated RGB lasers have rarely been reported because of the difficulties in integrating different lasers without cross-interaction among them. , Moreover, it is difficult to obtain a balanced white light laser due to the difficulties in the threshold values among RGB lasers …”
