One-way transparent optical system

摘要

An apparatus and method for microstructures of a display device which focus external light toward light-absorption regions to enhance brightness and contrast of the display device. The display device includes a light absorption layer disposed to one side of a light emission layer. The light absorption layer includes light refracting structures and light absorption elements, wherein each of the light absorption elements is positioned in the light refracting structures. The light directing structures substantially direct incident light toward one of the plurality of light absorption elements positioned therein to reduce the reflection of external light.
