AI Technical Summary
Existing organic light-emitting diode (OLED) displays suffer from non-uniform display quality due to variations in the characteristics of driving transistors based on their position, which affect charging rates and overall image quality.
The OLED display incorporates an overlapping layer that functions as a second gate electrode for the driving transistor, with different voltages applied during writing and light emission periods to mitigate characteristic deviations, including a driving voltage and an initialization voltage, thereby stabilizing the transistor's operation.
This approach enhances display uniformity by reducing the sensitivity of driving transistors to gate-source voltage changes, ensuring consistent output current and improved image quality across the display.
