Source Driver IC Regional Output Delay Compensation

The patent applies local quality by configuring different output delays for different regions (first and second regions) of the display panel. The first control logic circuit generates first output signals with a first output delay, while the second control logic circuit generates second output signals with a second output delay. This regional differentiation compensates for the increased RC delay in specific areas of larger display panels, maintaining timing margin without requiring uniform delay adjustment across the entire panel.

The patent implements local quality by regionally differentiating output delays to compensate for timing margin reduction at higher scan rates and resolutions. The first and second control logic circuits independently adjust output delays for their respective regions, enabling the system to maintain adequate timing margins even when overall scan rate and resolution are increased, thus supporting higher display quality without uniform timing compromise.

The patent applies local quality by implementing region-specific output delay compensation for fan-out effects. The first control logic circuit and second control logic circuit independently configure output delays tailored to their respective regions, enabling accurate compensation for fan-out variations across different areas of the display panel. This regional approach allows precise fan-out compensation that conventional uniform approaches cannot achieve.

The patent applies segmentation by dividing the display panel into first and second regions, each driven by separate control logic circuits. This segmentation allows independent optimization of output delays for each region, enabling accurate fan-out compensation even with reduced PCB size. By segmenting the control function, the system can manage fan-out complexity locally in each region rather than requiring uniform control across the entire panel.
