A display system and a method for display control of a gauge graphic is provided. The display system controls the display device to display the gauge graphic. The gauge graphic includes a scale and a needle movable on the scale. The scale includes a first region and a second region. The display system detects a first movement of the needle beyond a first threshold marking on the scale and towards an end of the first region and controls the display device to gradually unmask a first gradation pattern in the second region based on the detected first movement. The display system further detects a second movement of the needle over the second region and controls the display device to change the unmasked first gradation pattern so that the unmasked first gradation pattern flashes with a defined frequency in the second region based on the detected second movement.

A display device is configured to, when displaying an indicator needle as rotating with a relatively small rotation amount per unit time, display an indicator needle image while rotating the indicator needle image, and, when displaying the indicator needle as rotating with a relatively large rotation amount per unit time, display an indicator-needle motion-blurred image that corresponds to a rotation range per unit time of the indicator needle. An indicator-needle inner end angle formed by two sides of the indicator needle image that form an end thereof that faces a center of the rotation is equal to a minimum motion-blurred inner end angle formed by two sides of the indicator-needle motion-blurred image that has the smallest rotation amount per unit time while the indicator needle is displayed as rotating, the two sides forming an end of the indicator-needle motion-blurred image that faces the center of the rotation.

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.

A light guide pointer and a light emitting pointer device which can reduce luminance unevenness at a light emitting face are provided. A lower face of a main pointer portion includes a separating face extending away from a light emitting face, thus light reflected by a front inclined portion of a light control space, that is not likely to travel in a direction away from the light emitting face, is not likely to reach to a corner which is a boundary between the separating face and a recessed portion. Consequently, light is not likely to be reflected by the corner between the separating face and the recessed portion, thereby preventing luminance to be partially high at the light emitting face and thereby reducing luminance unevenness.

Systems and methods are disclosed and include a needle control module that includes a processor configured to execute instructions stored in a nontransitory computer-readable medium, a motor driver circuit in communication with the needle control module, the motor driver circuit controlling a stepper motor attached to a needle, and a housing enclosing the needle control module, the motor driver circuit, and the stepper motor, the housing being physically attached to a display of a vehicle. In response to the needle control module receiving a signal representing vehicle state information, the needle control module is configured to instruct the motor driver circuit to control movement of the stepper motor and adjust a position of the needle based on the signal.

A light ring assembly that is designed to provide bright, uniform and homogenized illumination and that can be used with any number of vehicle and non-vehicle lighting applications. According to one embodiment, the light ring assembly includes a housing, a circuit board with a number of individual light sources, a light ring and a lens. Light emitted by the light sources enters an optical input surface on a bottom side of the light ring, is reflected within the body of the light ring so as to mix and become more distributed, and then exits an optical output surface on a top side of the light ring.
