BOE’s Central Research Institute has made a major breakthrough in the research of high-resolution, full-color quantum dot light-emitting diodes (QLEDs), and has achieved full-color QLED devices with a resolution of 500 ppi and a color gamut of 114% NTSC, leading the world in technical indicators. Related research papers were published in the international authoritative academic journal Nano Research.
It is understood that quantum dot light-emitting diodes (QLEDs) are generally considered to be more disruptive next-generation display technologies after active matrix organic light-emitting diodes (AMOLEDs).
BOE 500PPI full-color QLED device lighting effect and sub-pixel arrangement
Since quantum dots are inorganic nanoparticles, they cannot be patterned using a vapor deposition process like organic small molecules, so inkjet printing was once considered to be a commonly used preparation process for QLED display.
However, due to the resolution limitation of inkjet printing (< 250ppi), high-resolution QLED patterning has become a common problem facing the industry.
It is reported that BOE's high-resolution QLED breaks through the limitation of resolution in traditional vapor deposition and inkjet printing processes, bringing the pixel density of QLED devices to a new height and expanding the application of QLED in the small and medium-sized high-end display product market.
BOE said that in the future, with the commercialization of QLED display, this achievement is expected to bring disruptive innovation to the display industry.
