Established in 2005 and headquartered in Zhubei, Taiwan, FocalTech Systems (TWSE: 3545) is a world-leading fabless IC design house devoted to human-machine-interface (HMI) solutions. The company pioneered capacitive multi-touch technology and is today the dominant global supplier of capacitive-touch-panel controller ICs, shipping more than one billion units cumulatively .

Core Competencies & Technology • Touch & Display Convergence: FocalTech was the first to mass-produce Super In-Cell (IDC/TDDI) chips that merge display-driver and touch-controller functions into a single die, enabling thinner, brighter and more power-efficient panels for smartphones, tablets, automotive and industrial displays .
• Broad Product Portfolio:
– Display Driver ICs for TFT-LCD, LTPS and AMOLED panels (1″–25″, up to 4K resolutions)
– Capacitive-touch controllers supporting 1–25″ screens, multi-finger, active stylus, water-touch and force-touch variants
– Fingerprint sensors (front, rear and side-mount) with ultra-low power and 360° recognition certified by Google BCR and Alipay
– Touch-pad modules for notebook, automotive and medical applications (glass, Mylar or flexible cover up to 3 mm)
• IP & R&D: Over 900 worldwide patents covering sensor algorithms, DSP, analog design and power-saving technologies .
