AI Technical Summary
Technical Problem
In existing organic light-emitting display devices, the storage capacitors have insufficient capacity and structural defects, which affect display performance.
Method used
The display device employs a three-layer passivation layer structure, in which the second passivation layer is made of amorphous silicon material with a higher dielectric constant than the other two layers, and ensures that it is not exposed to the outside, thereby enhancing the capacity and stability of the storage capacitor.
Benefits of technology
By increasing the capacity of the storage capacitors and improving structural defects, the display performance and reliability of the display device have been enhanced.
