Abstract
Display panels and methods of manufacture are described for down converting a peak emission wavelength of a pump LED within a subpixel with a quantum dot layer. In some embodiments, pump LEDs with a peak emission wavelength below 500 nm, such as between 340 nm and 420 nm are used. QD layers in accordance with embodiments can be integrated into a variety of display panel structures including a wavelength conversion cover arrangement, QD patch arrangement, or QD layers patterned on the display substrate.
