Definitions
- Head-up display with adjustable view window is adjustable.
- the present invention relates to an image generator, in particular for a head-up display with an adjustable view window, in particular for a motor vehicle.
- the invention also relates to a head-up display with adjustable view window.
- the head-up displays generally have the function of superimposing helper information, navigation or mission accomplishment, in the field of view of an aircraft pilot for example. It allows the pilot to monitor his environment at the same time as reading information provided by his instruments.
- these devices are also used in the automobile.
- Such devices include an image generator and a semi-reflective optical element configured to form a virtual image of the generator image.
- the virtual image is superimposed on the environment in the field of vision of the driver or driver.
- the vehicle windshield as a semi-reflective optical element to form the virtual image.
- the technical characteristics of such a device relate in particular to the position of the optical element with respect to the road and to the conductor, as well as to the angle of incidence of the image on the optical element, in particular to avoid distortion problems.
- the image generators known in the automobile include one or more light sources and a pixel array that receives the light beam from the sources.
- the matrix transmits or reflects the light beam by imparting an image that is formed by the pixels.
- Each pixel is individually controlled, and can either have a so-called "open” position, in which the incident light participates in the image, or a so-called “closed” position, in which the incident light does not participate in the displayed image. Thus, depending on the open pixels, an image is composed.
- Laser scanning can also be used as an image forming means.
- TFT Thin Film Transistor
- LCOS-type matrices for "Liquid Crystal on Silicon”, which means liquid crystals on silicon
- DMD-type micro-mirror matrices for "Digital Micro-Mirror Device”
- an observer sees the virtual image through the optical element, the virtual image appearing on one side of the optical element, while the observer is located on the other side of the optical element.
- the eyes of the observer must be positioned in a window of view, commonly called "eye box".
- the position of the viewport is defined by the position of the virtual image with respect to the optical element.
- it may be necessary to adjust the positioning of the view window to adapt it to an observer.
- it acts on the semi-reflective optical element to move it. Indeed, by changing, for example, the inclination of the optical element, we move the virtual image, and therefore the view window.
- the display is expensive to manufacture, and secondly, it is more bulky because of mechanical means.
- the inclination of the semi-reflective element only makes it possible to move the view window vertically. The invention therefore aims to improve the situation and to obtain a head-up display whose viewing window can be adjusted in all directions and in a simple manner.
- the invention relates to an image generator, in particular for a head-up display with an adjustable view window, in particular for a motor vehicle, the image generator being configured to display an image on a display surface; image being intended for a semi-reflective optical element arranged remote from the image generator and configured to form a virtual image of a first image of the optical element on the first side of the optical element, the virtual image being visible from a window of view located on a second side of the optical element.
- the image generator is notable in that it is configured to display the image on only a portion of the display surface and has means for moving the image on the display surface.
- the image generator it is sufficient to move the image on the display surface to move the view window of the head-up display, without resorting to mechanical means acting on the optical element for example .
- the display is therefore cheaper to manufacture and more compact.
- the display is more reliable because it does not include mechanical means that may wear out or break down.
- the displacement of the image on the display surface along a first axis makes it possible to move the view window vertically
- the display comprises means for detecting the position of an observer supplying a signal to the moving means
- the image generator comprises at least one light source capable of emitting a light beam, and a pixelation matrix configured to form the virtual image from the light beam,
- the pixellization matrix is a matrix of thin-film transistors
- the matrix of pixelation is a matrix of micro-mirrors
- the image generator is configured to form a substantially rectangular image.
- the invention also relates to a head-up display with an adjustable view window, in particular for a motor vehicle, comprising an optical element and comprising such an image generator.
- the optical element is a semi-reflective blade
- the optical element is part of a vehicle windshield
- the optical element has a curvature so as to carry at least partly the optical power necessary for the formation of the virtual image
- the display comprises at least one mirror arranged so as to reflect the image of the image generator towards the optical element.
- FIG. 1 schematically illustrating an embodiment of a display provided with an image generator according to the invention
- FIG. 2 schematically illustrating the displacement of the view window of the display of FIG. 1.
- FIG. 1 represents the operation of a head-up display 1, for example of a motor vehicle.
- the display 1 comprises an image generator 9, configured to display an image 7 on a display surface 2.
- the image generator 9 comprises for example at least one light source 1 1 able to emit a light beam, and a pixel array 10 configured to form the image 7 from the light beam.
- the light sources 11 are, for example, light-emitting diodes, which are arranged in a part of the generator.
- the generator comprises the pixel matrix 10, for example of the TFT type, on its output face. Thus, the diodes emit a beam to the matrix that prints an image 7 in transmission on the display surface 2 of the image generator 9.
- the image generator 9 is for example configured to form a substantially rectangular image.
- the display 1 also comprises a semi-reflective optical element 3 arranged at a distance from the image generator 9 and configured to reveal a virtual image 4 of the image 7 of the surface of a first side of the optical element 3. 2.
- the virtual image 4 is visible to an observer 6 if he looks at the optical element 3 while being placed on the other side of the optical element 3. As shown in FIG. 7 is reflected towards the observer 6, by a portion 8 of the surface of the element 3.
- the path of image 7 is represented by dashed lines.
- the optical element 3 thus forms a virtual image 4 of the image 7, which appears on the first side at a distance from the optical element 3.
- the observer 6 must be on the second side of the element optical 3, but in addition he sees the virtual image only if his eyes are inside a viewing window 5 located on the second side of the optical element 3.
- the dimensions of the view window 5 are defined in particular by the size and shape of the part 8 of the surface of the optical element 3 which reflects the image 7.
- the optical element 3 thus allows an observer 6 at a time to see the virtual image 4 and to see through the optical element 3.
- the 4 is superimposed in its field of view to the environment seen through the optical element 3.
- the optical element 3 is a semi-reflective plate.
- a portion of the windshield serves as a semi-reflective optical element.
- the rest of the display is arranged in the dashboard so as to use the windshield.
- a mirror is generally arranged on the optical path of the image so as to reflect it towards the part of the windshield.
- the optical element 3 has a curvature for carrying an optical power in order to make the virtual image 4 appear at a certain distance from the optical element 3 with a certain magnification, and thus to be superimposed suitably on the environment appearing in the observer's field of view 6.
- Optical power is a physical characteristic that determines the ability of an optical system to converge or diverge light. It is equal to the ratio between the angle at which the eye sees the output image of the system and the size of the object. The optical power thus makes it possible to adjust the size of the virtual image 4.
- the image generator 9 is configured to display the image 7 on only part of the display surface 2.
- this other part surrounds the displayed image in order to be able to move the image along several axes and thus to adjust the position of the viewport 5 in several directions.
- the image generator 9 further comprises displacement means 12 of the image 7 on the display surface 2.
- the displacement means 12 are, for example, a control unit of the image generator 9, which can be actuated by the observer 6 by means of buttons arranged on the generator or elsewhere.
- the display 1 comprises means 13 for detecting the position of the observer 6.
- the detection means 13 provide the moving means 12 with a signal corresponding to the position of the observer in order to adjust the position of the observer. the viewing window 5 by moving the image 7.
- the detection means 13 observe for example the position of the eyes of the observer to adjust the viewing window 5.
- FIG. 2 illustrates an example of vertical adjustment of the view window 5.
- the image 7 is displaced on the display surface along a first axis represented by an arrow 14.
- the reflecting portion 8 of the optical element 3 is consequently shifted, which causes a displacement of the virtual image 4 upwards, and which is represented by another arrow 15.
- the view window 5 rises as shown by a third arrow 16.
- the displacement means 12 of the generator 9 are configured to also move the image 7 on the display surface 2 along a second axis substantially perpendicular to the first.
