A display device comprising a display panel (10) and an electroluminescent light source (20), wherein the display panel (10) includes an intermediate layer and a display surface (12), wherein the electroluminescent light source (20) is configured to project light through the intermediate layer to form an information display on the display surface (12), and wherein the intermediate layer comprises one or more layers selected from crystalized calcium carbonate, porcelain, ceramics, china.

A horology component (1) for a timepiece, including a first portion (10) and a second portion (20), the first portion (10) comprising one part that is at least partially transparent and at least partially superposed on top of the second portion (20), this second portion (20) taking the form of a massive portion comprising a material capable of emitting at least one emission light wave if excited by at least one excitation light wave, and the at least partially transparent part of the first portion allowing an emission light wave emitted by the second portion (20) to be transmitted at least partially toward the outside of the horology component so that the horology component exhibits at least a first appearance by day and at least one different second appearance by night where the first portion (10) is backlit by an emission light wave emitted by the second portion (20).

A multiview 3D wrist watch includes clock circuitry to determine a time, and a plurality of light sources to generate a plurality of input planar lightbeams. A directional backplane having a plurality of directional pixels scatters the plurality of input planar lightbeams into a plurality of directional lightbeams. Each directional lightbeam has a direction and an angular spread controlled by characteristics of a directional pixel in the plurality of directional pixels. A shutter layer receives the time from the clock circuitry and modulates the plurality of directional lightbeams to generate a 3D time view.

A clock that runs along a path while lighting elements along the path. Each element along the path can be lit in a different color. One of the colors represents hours one represents minutes and the other represents seconds. Values which are lit continually change as times change, but this allows an artistic display of time.

The present invention relates to a timer configuring method and a timer using the same. The timer configuring method includes receiving, by a timer, a target time, and changing, by the timer, an area of a time display region on the basis of the target time and counting the target time. The area of the time display region is changed by rotation of a plurality of time display structures.

The invention concerns a timepiece (1), notably a diver's watch, comprising a case (2) provided with a case middle (3), a light source (6), an element (4) movable between several positions relative to the case (2), and movable means for assembling the movable element (4) on the middle part (3) of the case (2). More particularly, the movable element (4) includes a light guide (10) and an upper cover (9) comprising an index (5), the guide (10) being configured to receive a light beam (8) from the light source through an entry face (12), and to guide light rays (18) through an exit face (15) of the light guide (10) in order to illuminate the index (5), whatever the position of the movable element (4) relative to the case (2).

An active lighting device is placed on a person's wrist to light a path that the person is taking. The device is preferably in the form of a wristwatch. The device includes first light sources, which are controlled by a control unit. The first light sources are placed on a portion of a case. Each first light source activated by the control unit can produce a light beam of different orientation from another first light source activated by the control unit. The device further includes a motion sensor connected to the control unit to determine the wrist movement of the person wearing the device in order to allow the control unit to select certain first light sources to be activated depending on the person's wrist movement in order to light the path to be followed in the same defined forward direction.

A luminous electronic clock includes a multi-diameter forward tapered case frame; a transparent plate installed in a front circumferential edge of the case frame with a sealing ring mounted between them; a dial spaced behind the transparent plate and having time markers, temperature numbers and humidity numbers provided thereon; clock, thermometer and hygrometer movements mounted on a back side of the dial; hands of the clock and pointers of the thermometer and the hygrometer mounted on movement shafts and located on a front side of the dial; a set of LED lights installed around the clock movement shaft and located behind the dial; battery holders mounted behind the dial; and a case back fixedly held to a rear circumferential edge of the case frame by retaining springs and having windows corresponding to the movements and the battery holders.

The invention concerns a timepiece (1), notably a diver's watch, comprising a case (2) provided with a case middle (3), a light source (6), an element (4) movable between several positions relative to the case (2), and movable means for assembling the movable element (4) on the middle part (3) of the case (2). More particularly, the movable element (4) includes a light guide (10) and an upper cover (9) comprising an index (5), the guide (10) being configured to receive a light beam (8) from the light source through an entry face (12), and to guide light rays (18) through an exit face (15) of the light guide (10) in order to illuminate the index (5), whatever the position of the movable element (4) relative to the case (2).

An electronic device includes a display module having a hole and including a plurality of first light sources disposed along a perimeter of one side of the display module and a plurality of second light sources which are positioned opposite the plurality of first light sources and are disposed along a perimeter of the other side of the display module, a shaft rotatably inserted into the hole of the display module, a movement which is positioned in the rear of the display module, is connected to one end of the shaft, and provides a rotational force for the shaft, a window which is separated from the display module and is positioned in front of the display module, and a hand which is positioned between the display module and the window and is fixed to the other end of the shaft.
