Method of fabricating electroluminescent display
A method for fabrication organic light emitting diode (OLED) displays. A white light OLED element is formed on the first substrate. A micro-cavity layer is formed on a second substrate. A color filter is formed on the micro-cavity layer. The first and the second substrates are assembled, wherein the light of white OLED element passes through the color filter and the micro-cavity layer.
