Abstract

The invention discloses a touch key structure and a touch device. The touch key structure comprises a metal touch panel, wherein a plurality of metal keys are arranged on the touch panel, the keys and the touch panel are isolated through an insulation layer, and the touch panel is ground; a detection board is arranged below the touch panel, a plurality of electrodes corresponding to the keys are arranged on the detection board, and the detection board and the touch panel are in insulation isolation; and areas between the plurality of keys and the electrodes form flat capacitors. The touch key structure and the touch device have better restraint effect of an induction range, and avoid the interference of adjacent keys during touch identification.

Description

technical field [0001] The invention relates to touch sensing technology, in particular to a touch button structure and a touch device. Background technique [0002] At present, the types of consumer electronic products on the market are becoming more and more diversified, and users' requirements for the use experience of these consumer electronic products are also increasing day by day. The button system in consumer electronic products has become one of the key factors affecting user experience. Traditional mechanical keys are gradually being eliminated due to their abrupt appearance, unattractive appearance and difficulty in cleaning. At the same time, the limited service life of mechanical keys has also become one of the reasons for reducing user experience. Therefore, touch-sensitive keys have been gradually adopted in the market to replace traditional mechanical keys. Among them, the design of the capacitive touch key is also a hot spot in the technology of the touch-...
