Claim 0:
1. An organic light emitting diode (OLED) display panel, comprising:
a substrate;
a transparent conductive layer formed on a side of the substrate, wherein the transparent conductive layer is patterned to form a conductive electrode and a first electrode plate of a transparent capacitor;
a buffer layer formed on a side of the transparent conductive layer away from the substrate;
a metal oxide semiconductor layer formed on a side of the buffer layer away from the transparent conductive layer, wherein the metal oxide semiconductor layer is patterned to form an active layer of a thin film transistor and a second electrode plate of the transparent capacitor;
a gate insulating layer formed on a side of the active layer away from the buffer layer;
a gate layer formed on a side of the gate insulating layer away from the active layer, wherein the gate layer is patterned to form a gate of the thin film transistor;
an interlayer insulating layer formed on a side of the gate layer away from the gate insulating layer;
a source-drain layer formed on a side of the interlayer insulating layer away from the gate layer, wherein the source-drain layer is patterned to form a source and a drain of the thin film transistor, and the drain is connected to a drain region of the active layer, and the source is connected to a source region of the active layer and the conductive electrode; and
an OLED device layer formed on a side of the source-drain layer away from the interlayer insulating layer, and a light emitting direction of the OLED device layer faces the substrate.
