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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
