Simply put, quantum dot screen QLED is a hybrid of LCD and OLED, mainly using blue LED light sources to illuminate quantum dots to excite red and green light. Not only is the color gamut wider than OLED, but the screen brightness can also be 30% to 40% higher than OLED, while power consumption can be reduced by 30% to 50% compared to OLED. Quantum Dot LED screens can make a qualitative breakthrough in screens. According to media reports, Samsung and LG have started preparing to mass produce QLED screens in the second half of this year, and the high brightness and low power consumption characteristics of QLED screens seem to be most suitable for use in devices such as smartphones and tablets.
In fact, quantum dot technology is not a new thing that only exists now. Sony's TRILUMINOS primary color display technology is the result of using quantum dot technology, and Samsung and LG have also invested in related technology research and development three or four years ago. If the mass production of quantum dot screen QLED from these two manufacturers goes smoothly, there may be a chance to see new phones using quantum dot screen QLED released within this year.
