摘要:
An organic light emitting diode (OLED) display is disclosed. In one aspect, the OLED display includes a plurality of pixels in a matrix. The OLED display may include a substrate, a translucent layer formed on the substrate, a first electrode formed on the translucent layer, an organic light emitting member formed on the first electrode, and a second electrode formed on the organic light emitting member and including a reflective material. According to some aspects, the thickness of the organic light emitting member of the pixels forming the OLED display may be different than one another, or portions of each pixel may have different thickness for the organic light emitting members forming the pixel. With different thicknesses, the optical characteristics of the pixels forming the OLED display may be effectively compensated for luminance and color purity. As a result, the lateral viewing angle of an OLED display may be improved.
