Different from the backlight technology of photoluminescence quantum dots, amqled display does not need back light source, and can make quantum dots emit light by injecting current. It has the advantages of self luminescence, wide color gamut and long life, which has become the development direction of quantum dot display.
BOE (BOE) has made a series of progress in key technical problems such as uniformity and stability of large size quantum dot printing through technological innovation. The 55 inch 4K amqled display product is based on electroluminescent quantum dot technology, with resolution of 3840 × 2160, color gamut of 119% NTSC and contrast of 1000000:1.
