A shielding electrode above input-sensing MUX circuits diverts external static electricity while preserving reduced sensing pad count.
A grounded shielding electrode covers input-sensing MUX circuits to block external static electricity while preserving reduced pad count.
Threshold-based sensor stroke checks suppress finger tilt and placement artifacts on capacitive sliders, improving control accuracy.
Stacked keyboard layers and screen-mapped virtual keys expand command and symbol input on small PCs without complex shortcuts.
Press duration and captured audio time are used to switch between short-press and long-press voice input, matching user habits across software.
A movable software keyboard frees screen space for browsing or app access, enabling simultaneous touch operations in separate display regions.
