Abstract:
The invention relates to a projection system for a display, in particular a heads-up display, comprising a liquid crystal screen (12) and a back-lighting device (14) for said screen (12). The projection system is characterized in that said back-lighting device (14) comprises at least one light source (16) emitting light towards the screen (12), at least one lens (38a, 38b) suitable for collimating the light from the light source (16) towards the liquid-crystal screen (12), and reflective means (26) arranged on the surface of the lens (38a, 38b) located on the side of the light source (16), arranged such as to allow light to pass through same towards the screen (12) and to reflect towards the screen (12) almost all of the light propagating towards the lens (38a, 38b).
Abstract:
The invention relates to a compact head-up display (1), in particular for a motor vehicle, comprising: an image generator (9) for displaying an image (7) on a display surface (2); a semi-reflective optical element (3), typically a windscreen, arranged at a distance from the image generator (9) so as to form a virtual image (4) of the image (7) from the image generator (9) on a first side of the optical element (3), said virtual image (4) being visible from a view window (5) located on a second side of the optical element (3). The compact head-up display (1) comprises an optical part (10), typically a pentaprism, for extending the optical path of the image (7) passing therethrough from the image generator (9) to the optical element (3), said optical part (10) comprising an image input face (14) and an image output face (17), as well as first (15) and second (16) reflective surfaces. The first reflective surface (15) reflects the image from the input surface (14) towards the second reflective surface (16), and the second reflective surface (16) reflects the image (7) from the first reflective surface (15) towards the output surface (17), the input surface (14) also being substantially in contact with the display surface (2) of the image generator (9). The image generator (9) and the optical part (10) move together.
Abstract:
The system is characterised in that, the vehicle comprising a head-up-type display (34), said system comprises a gesture recognition device (26) that can supply data representative of a gesture made by the driver of the vehicle, and a control module (28) for processing the data, the control module (28) being designed so as to be able to control the display of at least one visual feedback (30, 32) on the display, upon reception of said data representative of the gesture made by the driver.
Abstract:
The invention relates to a device (1) for detecting the position of the face (2) of a person, in particular of a motor vehicle driver, wherein said device includes: a thermal sensor (4) configured for determining the heat generated from a target area (6) likely to be occupied by a person, in the form of a dot (10) matrix (8), each dot (10) in said matrix (8) representing the heat generated by a portion of said target area (6), processing means for analyzing a value acquired through a physical quantity for the dots (10) of said matrix (8) in order to detect at least one piece of adjustment information (12) that is representative of the position of said face (2) within said target area (6). The invention also relates to a corresponding detection method and display, in particular a head-up display, provided with said device.
Abstract:
A display unit (2) comprises a display (8), a plate (4) which is at least partially transparent and a structural part (6) comprising a rear portion (10) and a front portion (12) extending toward the plate (4) from the rear portion (10) while surrounding the display (8). The front portion (12) has a front face (30) extending at a constant distance from a rear face (32) of the plate (4) so as to form a bearing surface for the plate (4). The front portion (12) has at least one recess (28) arranged to form a passage between the rear portion (10) and the plate (4).
