Array substrate, method for fabricating the same, and OLED display device

摘要

This invention provides an array substrate, a method for fabricating the same, and an OLED display device, which can solve the technical problem that the existing OLED display device has low luminous efficiency. Each pixel unit of the array substrate comprises: a TFT drive layer; an OLED further away from the substrate than the TFT drive layer and driven by it, the OLED sequentially comprises a first electrode, a light emitting layer, and a transparent second electrode, wherein the first electrode is a reflection layer, or the first electrode is transparent and has a reflection layer disposed thereunder; a transflective layer further away from the substrate than the OLED and forming a microcavity structure with the reflection layer; and a color filter film disposed between the OLED and the transflective layer and located in the microcavity structure. The present invention is particularly suitable for a WOLED display device.

主权项

1. An array substrate, comprising a plurality of pixel units disposed on a substrate, wherein each pixel unit comprises:
a TFT drive layer; an OLED further away from the substrate than the TFT drive layer and driven by the TFT drive layer, the OLED sequentially comprising a first electrode, a light emitting layer, and a transparent second electrode in a direction away from the substrate, wherein the first electrode is a reflection layer, or the first electrode is transparent and has a reflection layer disposed thereunder; a transflective layer further away from the substrate than the OLED and forming a microcavity structure together with the reflection layer; and a color filter film disposed between the OLED and the transflective layer and located in the microcavity structure,
wherein color filter films of pixel units of different colors have different thicknesses so that microcavity structures of the pixel units of different colors have different thicknesses.
