Piezoelectric Actuators Displace Eccentric Rotating Mass Motors
Vendors are shifting roadmaps toward piezoelectric actuator arrays delivering localized, precisely timed tactile feedback across specific touchscreen zones rather than uniform whole-panel vibration. This matters increasingly as automakers consolidate multiple physical controls onto single display surfaces requiring distinct feedback signatures per function. Samsung Display, BOE Technology, and LG Display have each released new piezoelectric touchscreen modules in the past eighteen months, and automotive buyers in particular are specifying localized feedback as a mandatory qualification requirement rather than an optional feature for new cockpit design contracts. Smaller vendors favor this model since it differentiates products at lower incremental cost.
