ABSTRACT:
This invention provides an organic light-emitting diode (OLED) display device, in which a plurality of electro-luminescent units is sandwiched between a light reflective layer with an aperture array and a micro-lens array. A light absorbing layer is adjacent to a surface of the light reflective layer opposite to the electro-luminescent units. The ambient light entering the display can be focused to the apertures and directly projected unto the light absorbing layer to eliminate the ambient light. The contrast of the organic light-emitting diode display device is improved.
