Capacitive touchpad having dual traces coupled with uneven spaced interlaced sensors |
摘要 |
A capacitive touchpad comprises two traces with a plurality of first and second sensors coupled thereto respectively, and the first and second sensors are arranged interlaced and uneven spaced to each other. By detecting the capacitance variances produced by the sensors from the traces, phase leading or lagging Z-axis signals are generated to determine the moving direction of a finger sliding on the capacitive touchpad.
