Abstract

A vehicle seat with touch control function includes a seat armrest, the seat armrest includes an armrest frame, a flexible pad, a flexible touch panel, and a protective cover. The flexible touch panel is elastic, and the flexible touch panel includes a flexible substrate and a carbon nanotube touch function layer to collect touch input from a user. Such flexible touch panel may be installed on or in armrest of any seat in vehicle, enabling control of a display while comfortably seated, having to lean forward is avoided. A vehicle-mounted entertainment system incorporating such touch control system is also provided.
