Capacitive Touch Panel Electrode Segmentation for Faster Sensing

The patent divides continuous electrode strings into segmented electrode strings with multiple electrode segments along each string. This segmentation reduces the coupling capacitance between adjacent electrodes while maintaining the overall electrode structure. The electrode segments are separated by insulating structures, which further reduces parasitic capacitance and allows for optimized electrical performance without complicating the manufacturing process excessively.

By segmenting the electrode strings into multiple electrode segments with insulating structures between them, the patent reduces the coupling capacitance between adjacent electrodes. This allows for increased electrode density along the same row or column to improve detection accuracy, while the segmentation prevents excessive accumulation of capacitance and resistance that would otherwise occur with continuous electrode strings.

The patent enables simultaneous detection along both row and column directions by implementing a detection mechanism that can process multiple electrode strings in parallel. The segmented electrode structure with reduced coupling capacitance allows for faster signal response, enabling the system to check multiple rows and columns simultaneously rather than sequentially, thus reducing overall detection time while maintaining process simplicity.

The segmented electrode string design reduces the coupling capacitance between adjacent electrodes, which decreases the overall system loading. This reduction in loading allows for faster detection speeds even when using a moderate number of electrodes, eliminating the need to use excessive electrodes to achieve fast detection. The segmentation optimizes the balance between detection speed and system loading by reducing parasitic effects.
