The hybrid timekeeper, such as a watch, comprises a classical part with at least a mechanical movement with hands to indicate a time measure on a dial, a crown and a rotating winding mass, and a smart module, both classical part and smart module being combined in a same watch case. The timekeeper in combination with a portable phone can be the parts of a general communication ecosystem.

A teaching aid for those learning to tell time and learn the alphabet of a language. The teaching aid includes an interactive touchscreen alphabetic display. The present invention may assist in teaching the alphabet through providing a tactile-interactive medium, the touchscreen alphabetic display, for a user to select specific alphabetic characters and be provided visual feedback in the form of an image associate or corresponding with each selected alphabetic character. The teaching aid also provides a clock display for teaching time to the user.

A display device includes a substrate having a through-hole. The display device also includes a display unit formed on the substrate and surrounding the through-hole, and the display unit is configured to display an image and includes pixels.

An electronic device includes a display including a transparent area through which content is output and through which external light passes and a processor electrically connected to the display. The processor is configured to obtain information about an overlap location of an external device and the electronic device, to execute a function mapped to the information about the overlap location, and to output a screen associated with the function on the transparent area.

The present invention is to reduce an increase in a processing load when a background image is displayed in addition to pointer images indicating pointer movements. A control section displays a plurality of pointer images indicating pointer movements in a timepiece display area of a display section based on time information acquired from a clock circuit. Here, the control section identifies an area where the plurality of pointer images are displayed, such as a pointer movement area or a pointer presence area in the pointer movement area, and controls to perform high-load and low-load display operations with different processing loads on the identified area and an area other than the identified area, such as an outer area outside the pointer movement area or a pointer absence area in the pointer movement area, respectively.

The present invention provides a laser projection clock, comprising a driving device, one or a plurality of pointer light source device, and one or a plurality of grating. The driving device comprises one or a plurality of rotating shafts and power elements for driving the one or plurality of the rotating shafts to rotate at different speeds respectively. The one or plurality of pointer light source devices is configured on one side of the driving device to each output a laser beam. The one or plurality of gratings is configured on the one or a plurality of rotating shafts in a one-on-one manner in order to be rotated by the one or plurality of rotating shafts respectively. The grating has an indication pattern, and the one or plurality of laser beams are projected to a projection plane through the one or a plurality of indication patterns of the one or plurality of gratings to form one or plurality of laser indications respectively.
