Abstract
Embodiments of a display device are described. The display device includes a first sub-pixel with a first quantum dot (QD) film and a first filter element. The QD film receives both UV light and blue light and converts a portion of the received light to emit a secondary light different from the UV and blue light. The filter element is disposed on the quantum dot film and allows the secondary light to pass through the filter element, and the filter element blocks an unconverted portion of the received light from passing through the filter element. The second sub-pixel has a second filter element that allows blue light to pass through the second filter element, and the second filter element blocks the UV light from passing through the second filter element.
