Display Driver Circuit Sensing Time Reduction

The patent applies preliminary action by equalizing the sizes of driving transistors in different subpixels before the sensing process. This pre-adjustment ensures that all subpixels have substantially equal sensing times, allowing the sensing operation to start and complete simultaneously across all subpixels. As a result, the sensing time is determined by the longest subpixel (which is now equal to others), eliminating the need to wait for the slowest subpixel to finish sensing, thus significantly reducing total sensing time while maintaining accuracy.

The patent changes the physical parameter of transistor size (specifically channel width and length) to equalize sensing characteristics across different subpixels. By adjusting these geometric parameters, the patent ensures that all driving transistors have substantially equal on-currents and sensing times, transforming a variable sensing process into a uniform one that completes simultaneously across all subpixels, thereby optimizing the time-efficiency tradeoff.

The patent performs preliminary size equalization of driving transistors before sensing begins. This pre-conditioning ensures that all subpixels are ready to sense at the same rate and complete sensing simultaneously. Consequently, the sensing operation can be performed in parallel across all subpixels without creating bottlenecks, significantly reducing the total sensing time required and improving operational efficiency while still enabling comprehensive luminance deviation compensation.

By changing the transistor size parameters to achieve uniform characteristics across all subpixels, the patent enables simultaneous and efficient sensing operations. This parameter standardization allows the sensing process to complete in the time required for a single subpixel rather than requiring sequential sensing or waiting for the slowest subpixel, thereby improving productivity while maintaining the ability to compensate for luminance deviations.

The patent changes the transistor size parameters (channel dimensions) of driving transistors in different subpixels to achieve substantially equal on-currents and sensing times. This parameter equalization transforms the sensing process from one with varying times to one with uniform sensing characteristics across all subpixels, eliminating sensing time deviation while preserving the ability to accurately sense each subpixel's characteristics.

The patent creates equipotentiality in the sensing process by equalizing the driving transistor characteristics across all subpixels. This ensures that all subpixels have substantially equal sensing capabilities and complete sensing at the same time, eliminating the time deviation that would otherwise occur. The sensing process becomes synchronized across all subpixels, maximizing overall efficiency while maintaining individual sensing accuracy.
