Assignee: DARWIN PRECISION CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G

Claim 0:
1. A non-contact key, comprising:
a frame, including an accommodating cavity;
a touch module; and
a display module, disposed in the accommodating cavity and comprising:
a first light source, emitting light;
an optical unit;
an imaging unit, arranged on a side of the optical unit facing away from the first light source and having a preset pattern, wherein the preset pattern is a constant static image designed according to a default floating image; and
a lens array, arranged on a side of the imaging unit facing away from the first light source,

wherein corresponding to the preset pattern, the light emitted by the first light source passes through the optical unit, the imaging unit, and the lens array to form the default floating image in a floating display area outside the accommodating cavity,
wherein the touch module is configured to establish a floating touch area outside the accommodating cavity, such that the floating display area at least partially overlaps the floating touch area,
wherein the touch module is an ultrasonic touch module disposed adjacent to the first light source, and
wherein the non-contact key is arranged as one of a plurality of non-contact keys having similar architecture and disposed adjacent to each other in an array such that there is no interference between the respective floating touch areas of adjacent non-contact keys.
