Abstract
Disclosed is a top-emitting WOLED display device. An optical turning layer with a uniform thickness is added between anode layers of three sub-pixels R, G and B and a reflective metal layer of the display device. Because of arrangement of the optical turning layer, a distance between a WOLED layer and a reflective metal layer is increased. Thus, a total cavity length of a white OLED is increased, and a microcavity effect of a top-emitting WOLED is overcome. The optical turning layer is suitable for manufacture of AMOLED display devices with high-resolution and color gamut.
