Abstract
An input device is provided in the present application. The input device includes a first panel and a second panel, the first panel is provided with multiple grooves; the second panel is located under the first panel or fused to a bottom of the first panel, and includes a sensing unit configured to sense a key. In the input device, each of the grooves is arranged to correspond to one key area, and a key command may be input by performing a touch key operation on a corresponding sensing unit under the groove. Compared with the conventional input device, in the input device of the present application, the input of the key command may be realized without key caps and scissor-shaped structures for supporting the key caps, thereby shortening the key travel and reducing the thickness of the input device.
