  • Patent number: 9829757
    Abstract: A display device includes a light source module, a first light modulation module, a first polarizer layer, and a first color modulation layer. The light source module generates a first color light that is polarized to the first light modulation module, wherein the first light modulation module selectively modulates the polarization direction of the first color light. The first polarizer layer then receives the first color light and selectively blocks, partially blocks, or does not block the first color light from passing through. The first color modulation layer receives the first color light and generates a second color light.
