A picture generation unit (PGU) used in a head-up display (HUD) includes a printed circuit board (PCB) having a plurality of light sources, a display unit disposed in front of the plurality of light sources and configured to form an image to be provided to the HUD, and a housing disposed between the PCB and the display unit and including an internal reflective structure configured to guide optical beams from the plurality of light sources to the display unit and to homogenize a light intensity of the optical beams incident on the display unit, wherein the internal reflective structure includes a plurality of first funnels respectively disposed of corresponding to the plurality of light sources, and a second funnel disposed of as a singular funnel in front of the first funnels in a form encompassing the plurality of first funnels.

A dynamic light source for a display is disclosed. The dynamic light source comprises a first light source located inside a first device; and a second light source. The first device is configured to allow light from the first light source to exit the first device in a first cone of angles and to reflect light incident outside the cone of angles back towards the first light source. The first device is configured such that injected light from the second light source is reflected by the first light source in a second cone of angles substantially coincident with the first cone of angles and that light output by the first device from the second light source is attenuated more than light output by the first light source, and an amount of attenuation is based on an intended dynamic power range of the dynamic light source.

A motor vehicle includes a passenger display with a switchable view protection device that is actively switched in predetermined operating states so that display contents shown on the passenger display cannot be seen from the seating area of the driver. The vehicle includes a shading device having an illuminant oriented toward the passenger display and is controlled by a control unit and which, in order to prevent moving residual fragments that can still be detected from the driver’s seat despite a view protection device which is switched to shading, externally illuminates the passenger display.

A vehicle interior component configured to provide a user interface for vehicle systems is disclosed. The component may provide a user interface for a vehicle occupant. The component may comprise a composite structure to provide the user interface comprising a cover providing an exterior surface, a sensor, light panel, absorber panel and/or decorative material. The light panel may provide output visible at the exterior surface; the decorative layer and/or absorber panel may provide a visual effect. The cover may comprise a light-transmissive cover; illumination from a display may comprise visible light transmitted through a functional layer and through an at least partially translucent cover. The component may comprise a light panel to provide output visible at the cover exterior surface. A method of operating the user interface provided by the composite structure is also disclosed. The user interface may be coupled to a control system.

According to one embodiment, a display device includes a display panel configured to modulate a first polarization component, a first viewing angle control panel including a first liquid crystal layer containing twisted liquid crystal molecules, a second viewing angle control panel including a second liquid crystal layer containing twisted liquid crystal molecules, and a polarization axis rotation element provided between the first viewing angle control panel and the display panel. A second polarization axis of a second polarization component which passed through the first viewing angle control panel is different from a first polarization axis of the first polarization component. The polarization axis rotation element is configured to rotate the second polarization axis.

A light guide body in a display device includes a first incident surface on which an image light is incident, and a second emission surface from which the image light is emitted. The light guide body includes a second emission optical element that diffracts the image light to emit a portion of the image light at a predetermined emission angle every time the image light enters the second emission optical element from a predetermined direction. The image light is diverged by being emitted from the second emission optical element such that the predetermined emission angle varies in accordance with a location in one predetermined region included in a plurality of predetermined regions of the optical element. The degree of divergence varies between the one predetermined region and other predetermined region included in the plurality of predetermined regions in accordance with the location of the virtual image.

A display system may include a camera configured to capture an image of a calibration reference associated with an automobile, a display, and a controller in communication with the camera and the display. The controller may be configured to selectively adjust a color temperature of the display based on the image of the calibration reference.

A display panel has a first and second layers and a control unit. The first layer is a pixel matrix. The control unit is designed to actuate at least one pixel element for displaying at least one graphic display object. In a respective non-actuated state each pixel element is transparent. The second layer is partitioned into predetermined primary subareas each having an adjustable degree of light transmission. The primary subareas are separated by a primary space. The control unit is adapted to adjust a respective light transmission to a predetermined individual degree for each of the predetermined primary subareas independent of each other. The display panel also has a third layer designed to attenuate light in the primary space.

A display device for a vehicle includes: a first transparent or translucent layer comprising a pictogram, a second transparent or translucent layer, covering the pictogram, a liquid crystal display, arranged in line with the pictogram, and a light source configured to emit light to illuminate the pictogram by passing through the liquid crystal display and the second layer. The liquid crystal display at least partially covers the second layer, and an assembly formed by the first layer and the second layer is rigid.

An operating method of an optical system in a vehicle is provided. The optical system includes a display device. The display device includes a display panel and a plurality of light emitting units. The light emitting units are configured to emit a light to the display panel. The operating method includes the following steps. An emphasized portion of an object is determined. An image corresponding to the emphasized portion is displayed by the display device by adjusting a light intensity of at least a portion of the light emitted from the light emitting units.
