A display device (100) for displaying at least one symbol has a translucent cover layer (210), a symbol layer (213) having a translucent symbol panel (216) for a symbol that is to be displayed by the display device (100), and an opaque surface (214) encompassing the symbol panel (216). The symbol panel (216) is disposed such that it is spaced apart from the cover layer (210) by a gap (226). A waveguide assembly (228) is formed in order to conduct light (232) onto a side of the symbol panel (216) facing away from the cover layer (210).

Exemplary embodiments of this disclosure provide a display system that integrates a mechanical indicator assembly in an overlapping manner with one or more displays in an instrument panel. An instrument panel may include a mechanical indicator assembly including a pointer configured to rotate about an axis and thereby define an area swept by the pointer, a transparent display, a housing configured to support the mechanical indicator assembly and the transparent display overlaying the mechanical indicator assembly, and a control system configured to display, on the transparent display, content including text and/or graphics.

An on-vehicle meter includes a meter including an indicator that rotates about a certain axis, a transparent display device provided on a display side of the meter, a light guide plate provided between the meter and the transparent display device, a light source that emits light to the light guide plate, and a control device that controls a display state of the transparent display device and the light source.

A vehicle display device includes an indicator that luminously displays a display image on its screen by lighting and stops the luminous display of the display image by extinction, and a display panel that includes a light shielding part on a rear surface of the display panel. The light shielding part light-shields a surrounding part of a transmitting window, through which an image light of the display image is transmitted to be capable of being visually recognized from a front side. A transmission region of a front surface of the display panel that is located at least on the front side of the transmitting window is occupied by a planar part that is formed in a flat surface shape along the screen, and a plurality of projecting surface parts that project from the planar part into a curved projecting surface shape. An area occupancy of the planar part at the transmission region is adjusted to be equal to or larger than an area occupancy of all the plurality of projecting surface parts at the transmission region.

A display device for a vehicle includes: a ring portion and a moving mechanism to display various vehicle information associated with a travel of the vehicle for a viewer within a display area. The ring portion forms an outer periphery of an indicator indicating at least one vehicle information of the various vehicle information, and is visually recognized as a virtual image within the display area. The moving mechanism is able to move a position of the ring portion.

The disclosure relates to a system, a method, and an apparatus to selectively control brightness of information displayed on a Liquid Crystal Display (LCD). A graphics layer can be provided in a display area of the LCD, and a semi-transparent mask layer can be provided above the graphics layer. An information graphics layer can be provided above the semi-transparent mask layer. The information graphics layer can be controlled to selectively display predetermined information on the LCD at an intended brightness, while remaining information from the underlying graphics layer can be dimmed relative to the brightness of the display predetermined information by activation of the semi-transparent mask layer.

A vehicle instrument device includes a housing for attaching a dial plate, a light guide plate housing recess formed in the housing, a light guide plate that is housed in the light guide plate housing recess, and guides illumination light to the dial plate, a claw that fixes the light guide plate to the housing, and a press-fitting rib that is provided in a side surface of the light guide plate, and extends toward a side wall of the light guide plate housing recess. The press-fitting rib includes a tapered portion for increasing a height from a back side to a front side of the light guide plate housing recess and a tapered portion for decreasing a width from the back side to the front side of the light guide plate housing recess.

A dial assembly is provided that includes a dial surface including a flat surface and a plurality of lines formed on the flat surface projected from a 3D object that generate a 3D appearance. One or more light sources illuminate each of the lines of the plurality of lines. A method of forming a dial assembly is also provided. The method includes dividing a subject 3D dial with a plurality of equidistant planes and projecting edges of the planes onto a flat dial surface to form a plurality of lines to generate a 3D appearance on the flat dial surface.

Described herein are deadfront assemblies that are configured to exhibit variable transmission and reflection performance attributes. The deadfront assemblies described herein comprise a first ink layer, an intermediate layer, and a second ink layer. The intermediate layer is disposed between the first and second ink layers and is configured to reflect light that is transmitted through the first ink layer back through the first ink layer so that one or more colors of the ink in the first ink layer is visible in the reflected light. The second ink layer is configured to counteract deviations in optical transmission caused by the first ink layer so that light transmitted through the deadfront assembly is not perceptively altered in color. Overlapping regions of the first and second ink layers comprise inverse appearance attributes so that light output from a light source and transmitted through the deadfront assembly has a desired appearance.
