A panel device includes a panel unit, a light-blocking layer, and an indicator light projector. The light-blocking layer is located between the panel unit and the indicator light projector, specifically, on a rear surface of the panel unit. The indicator light projector is located relatively close to the light-blocking layer. When indicators displayed on the panel unit are viewed from the outer side, representations provided by the indicator light projector are visually recognizable even when viewed from an angled position.
1. A panel device, comprising:
a panel unit that is light-transmissive and one of colored or colorless;
a light-blocking layer including an indicator opening that is shaped in correspondence with an indicator to indicate when a device is activated; and
an indicator light projector that emits light from a rear side of the panel unit, the indicator light projector including a lens that transmits the emitted light to the panel unit to display the indicator on the panel unit with the light passing through the indicator opening,
wherein a front surface shape of the lens is larger than an opening shape of the indicator opening, and
wherein the light-blocking layer is located between the panel unit and the indicator light projector.
2. The panel device according to claim 1 , wherein the light-blocking layer is arranged on a rear surface of the panel unit.
3. The panel device according to claim 1 , wherein the panel unit includes a black background corresponding to a color of the light-blocking layer.
4. The panel device according to claim 1 , comprising:
an indicator portion that includes
the indicator opening, and
the indicator light projector that emits light from the rear side of the panel unit to the indicator opening to display the indicator, which is shaped in correspondence with the indicator opening, on the panel unit.
5. The panel device according to claim 4 , wherein the indicator portion is one of multiple indicator portions, and the multiple indicator portions are arranged adjacent to one another.
6. The panel device according to claim 1 , comprising:
a display that includes
a window frame arranged in the light-blocking layer, and
an image displaying unit that projects an image from the rear side of the panel unit through the window frame onto the panel unit to display the image on the panel unit.
7. The panel device according to claim 1 , comprising:
a symbol portion that includes
a mark opening arranged in the light-blocking layer,
a mark light projector that emits light from the rear side of the panel unit to the mark opening to display a mark, which is shaped in correspondence with the mark opening, on the panel unit, and
a detector arranged inward from the mark opening to detect when the panel unit is touched at the mark.
