Pixel Driving Circuit Segmentation for Dynamic Power Reduction

The patent divides the data signal input into two separate data input modules (first and second data input modules) that operate at different time periods. The first data input module inputs data during a first time period, and the second data input module inputs data during a second time period. This segmentation allows the circuit to achieve the required light emission current through sequential voltage application rather than simultaneous high voltage, thereby reducing dynamic power consumption while maintaining sufficient drive current for the light-emitting element.

The patent segments the data input process into two distinct time periods with two separate data input modules. By applying voltage sequentially rather than simultaneously, the peak current demand is reduced, which in turn reduces resistive heating (I²R losses) in the circuit components. This temporal segmentation maintains adequate light emission intensity while preventing excessive temperature rise that would cause device characteristic drift.

The patent implements segmentation of the data input operation into two time periods using separate data input modules. This approach maintains sufficient light emission intensity by ensuring the light-emitting element receives adequate voltage, while the sequential operation prevents the simultaneous high current draw that causes voltage drops and signal interference. Consequently, display performance remains stable and abnormal phenomena are avoided.

The patent introduces a second data input module in addition to the first, creating a segmented data input architecture. While this increases circuit complexity compared to a single input module, it enables the circuit to achieve sufficient light emission current through sequential voltage application. The segmentation allows each input module to operate at lower voltage levels while still providing adequate total drive current, thus avoiding the need for high voltage operation.
