WIPO Patent Application WO/2018/068679
Kind Code:
A1
Abstract:
A touch key apparatus. The touch key apparatus comprises a touch panel (1), a touch spring (2), an LED planar tube (3), and a touch sensor (5) provided with a capacitance detection element (4). The touch spring (2) is connected to the capacitance detection element (4) and is disposed between the touch panel (1) and the touch sensor (5), the LED planar tube is disposed in an inner cavity of the touch spring (2) or outside the touch spring (2), and a light emitting part of the LED planar tube (3) is directed at the touch panel (1). A touch key device is also provided, that can emit light uniformly and on which touch key operations can be performed without resetting a touch sensor template, therefore achieving low production costs.
