    Abstract: A display panel includes at least one pixel unit. The pixel unit includes a first sub-pixel, a second sub-pixel, a third sub-pixel and a fourth sub-pixel. The first, second, third and fourth sub-pixels include a first color filter portion, second color filter portion, a third color filter portion and a fourth color filter portion, respectively. The first, second and third color filter portions are configured to emit light of three primary colors. A material of the fourth color filter portion includes at least one light conversion material configured to convert a portion of light directed to the fourth color filter portion into light of at least one primary color. The light of at least one primary color is capable of being mixed with another portion of the light directed to the fourth color filter portion to generate white light.
