  • Patent number: 10263220
    Abstract: The manufacturing method for QLED display of the present invention uses the white QD layer to replace the organic light-emitting layer of the WOLED structure in the WOLED process, and adds the UV photoinitiator to the white QD layer. The QDs between the sub-pixels are irreversibly quenched by UV irradiation with mask to form fine QD pattern so as to eliminate the mutual influence between adjacent sub-pixels and effectively reduce the distance between two sub-pixels, increase the aperture ratio, and improve the color gamut and contrast of the display to enhance the color expression capability of the display. The manufacturing method is simple, and saves cost and process. Compared with the conventional TFT-LCD display, the QLED display of the present invention is not required to fabricate a liquid crystal cell separately, thinner and lighter, and has a longer lifetime and higher luminous efficiency than a conventional WOLED display.
