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.

Provided are a bezel body and a vehicular display device that effectively reduces a sense of discomfort provided to a passenger by making reflection on a windshield less visible. Since a reflection portion is formed in a predetermined area on a lower surface of a light guide member at the rear side, the guided external light is easy to reflect upward, whereby light can efficiently be emitted from the light guide member toward a descending wall. Therefore, this configuration can prevent the descending wall from being darkly reflected on a windshield, thereby making the reflection less visible and effectively reducing a sense of discomfort provided to the passenger.

The disclosure is directed to methods and systems for modifying a vehicle periphery. These methods and systems include receiving a notification that an attachment is placed on the vehicle, detecting, with one or more sensors located in or on the vehicle, the location and size of the attachment on the vehicle, forming an attachment periphery of the attachment's size and location, forming a representation of the attachment periphery relative to the vehicle periphery and monitoring, with the one or more sensors, the surroundings of the vehicle to determine if an obstacle is within a predetermined distance of the attachment periphery or the vehicle periphery.

An assembly includes a light guide having a proximal end and a distal end. The proximal end has a light-emitting diode package coupled thereto. The assembly may include another light guide, also having a proximal end and a distal end, with a light-emitting diode package coupled to the proximal end. A light housing may be included that defines a cavity therein, wherein at least a portion of the first and second light guides including the distal ends are disposed in the cavity. Further, a dial face may be included that is disposed adjacent to the first and second light guides and the light housing, wherein each of the first and second light guides are configured to illuminate the dial face. In some variations, flexible printed circuit boards are attached to and electrically connected with the light-emitting diode packages.

An attenuation portion is to illuminate first and second display objects while attenuating light. A display element causes light to enter the attenuation portion to illuminate the first display object in a display region. A light source irradiates light to illuminate the second display object in the display region. A display forming member has a light-blocking layer and an attenuation layer. The light-blocking layer has a light-transmitting portion defining a shape of the second display object. The attenuation layer covers the light-blocking layer from a display region side to attenuate light, which is from the light source and passes through the light-transmitting portion. The display forming member indicates the second display object in the display region with emission of light which is attenuated through the attenuation layer and enters the attenuation portion.

A liquid crystal display device includes a backlight module configured to switch between first light having a maximum luminance in a first direction and second light having a maximum luminance in a second direction different from the first direction and emit the first light and the second light from a main surface, a liquid crystal display panel, and a control device. The control device receives a first image and generates a first offset image based on the first image, the first offset image being an image obtained by reversing a color of the first image and having a luminance adjusted, controls the liquid crystal display panel such that a first display image including the first image and a second display image including the first offset image are alternately displayed, and controls the backlight module so that the first light is emitted when the first display image is displayed and the second light is emitted when the second display image is displayed. A luminance of the first offset image is substantially equal to a luminance in the second direction when the liquid crystal display panel displays the first display image.

In an instrument panel, a LED backlighting device has at least one LED source, the optical axis of which corresponds to the direction in which the intensity of the emitted light is maximum. The light of the LED source is reflected onto a graphic area by a first and a second reflecting surface. The first surface defines a first cavity and is aligned with the graphic area along an illumination axis spaced apart from the optical axis, while the second surface is aligned with the LED source along the optical axis and defines a second cavity communicating with the first cavity through an aperture. The second surface is a cylindrical surface, defined by an elliptical generatrix and configured so as to block the light rays that would be directed from the LED source onto the graphic area.

A method, system, and devices for implementing a selectively lighted instrument cluster are disclosed herein. The aspects employ a light house layer (or collection of light house layers) using a combination of light and dark materials to provide individually lit indicia on a cover layer (i.e. applique layer) of an instrument cluster. The combination of light and dark layers selectively applied prevents light leakage into other non-intended portions on the viewable surface of the instrument cluster.

A dial gauge assembly includes a single circuit board that supports light emitting diodes for both illuminating a pointer and backlighting a liquid crystal display. The dial gauge assembly controls illumination of the pointer by switching on and off a plurality of segments disposed within the LCD.

The present technology relates to a vehicle projection system comprising a light source configured to provide an output beam. A light splitting device is coupled to the light source to receive the output beam. Two or more optical fibers are coupled to the light splitting device to receive a split output beam from the light splitting device. Two or more projector devices are coupled to the two or more optical fibers. The two or more projector devices are configured to provide one or more display images using light received from the split output beam on one or more display surfaces in a vehicle. A vehicle including the vehicle projection system and a method of providing display images at a plurality of locations in a vehicle are also disclosed.
