Multi-touch automotive HMI enables independent driver and passenger touch zones on car dashboards using capacitive touch overlays (CTP) on high-brightness TFT LCDs like CDTech’s 2300 nits S070QWU142FN-FL150-GF. Patented 2nd Cutting technology (developed 2017) delivers custom stretched bar LCD automotive sizes (4.3″-12.3″) with OCA bonding for sunlight-readable, wide-temp (-30°C~+85°C) operation, ensuring seamless multi-zone control. IATF16949-certified for OEM reliability.

How Does Multi-Touch Automotive HMI Work in Car Dashboards?

Multi-touch automotive HMI uses capacitive touch panels (CTP) layered on automotive touch display TFT LCDs to detect 10+ simultaneous points, enabling gestures like pinch-to-zoom or swipe across zones. Software-defined partitions create driver passenger touch zones, such as left for navigation and right for infotainment, preventing interference. CDTech’s full vertical integration from LCD cutting to OCA bonding delivers anti-glare, sunlight-readable performance.

What Makes Stretched Bar LCDs Ideal for Multi-Zone Dashboards?

Automotive touch bar and stretched bar LCD automotive designs like CDTech’s 7.0″ S070QWU142FN-FL150-GF (1200×1920, 2300 nits) and 12.3″ S123BWU11EP fit curved dashboards perfectly. Narrow aspect ratios support side-by-side driver/passenger panels with independent multi-touch automotive HMI. CDTech’s patented 2nd Cutting creates non-standard sizes, cutting NRE costs and lead times to 6-8 weeks.
