Pixel Circuit Segmentation for Display Power and Flicker Control

The pixel circuit is divided into two independent driving circuits: a first driving circuit (including first driving transistor and first capacitor) controls the brightness of the light-emitting device, while a second driving circuit (including second driving transistor and second capacitor) controls the duration. This segmentation allows independent optimization of brightness and duration control, enabling the circuit to reduce power consumption by separately managing these two parameters without requiring a completely redesigned complex circuit architecture.

The pixel circuit dynamically adjusts the light-emitting duration and brightness through separate control mechanisms. The first driving circuit dynamically controls the current magnitude to the light-emitting device for brightness adjustment, while the second driving circuit dynamically controls the duration of current flow. This dynamic control allows the circuit to extend illumination duration when needed for visibility while maintaining appropriate brightness levels, thereby managing power consumption effectively and reducing flicker sensitivity-related user discomfort.

The control functionality is segmented into two distinct control circuits: the first control circuit (first driving transistor and first capacitor)专门 controls brightness by managing current magnitude, while the second control circuit (second driving transistor and second capacitor)专门 controls duration by managing current flow time. This segmentation provides independent and precise control over brightness and duration parameters, significantly improving ease of operation and control capability. The modular segmented structure allows each sub-circuit to be optimized for its specific function without unnecessarily increasing overall device complexity.
