Problems solved by technology

In short, the driver sees the displayed image on the outside of the vehicle (outside the windshield), but does not perceive the displayed image on the inside of the vehicle (inside the windshield) at all
[0005] As described above, even with a conventional head-up display device using a virtual image, it is not possible to provide the driver with any image displayed in both spaces outside the windshield (vehicle outside) and inside (vehicle inside)

Embodiment Construction

[0040] A head-up display device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0041] figure 1 It is a schematic perspective view showing a dashboard of a vehicle such as an automobile and its periphery including the head-up display device 1 according to the embodiment of the present invention. figure 2 and image 3 These are a schematic cross-sectional view and a perspective view illustrating the operation of the head-up display device 1 , respectively.

[0042] The head-up display device 1 is made by applying the present invention to the upper part of the instrument panel 2 in front of the driver's seat of the car (including the space above it: viewer's side), using the windshield 7 as a reflective screen. Specifically, the head-up display device 1 has a dihedral reflector array 6 as a real image imaging optical system incorporated into the upper portion of the instrument panel 2, and is placed in...

Abstract

A head-up display device placed on an upper surface of a dashboard, includes: an object of view arranged in an inside space of the dashboard; an imaging optical system of real specular image for defining a space where a viewer exists and the inside space of the dashboard, the imaging optical system of real specular image including a semitransparent substrate with a plane of symmetry, the imaging optical system of real specular image forming a real image of the object of view in the space of the viewer with light passing through the substrate; and a reflective screen arranged in the space of the viewer, the reflective screen reflecting light beams of the real image of the object of view supplied from the imaging optical system of real specular image to guide the reflected light beams to the viewer, while allowing formation of an image to be seen by the viewer.

Description

technical field [0001] The present invention relates to a display device as a device for displaying information for a driver in a vehicle, in particular to a head-up display device. Background technique [0002] In a vehicle such as an automobile, a driver is given various displayed instrument information such as speed, engine revolutions, etc. via eg a speedometer, a tachometer, etc. in a so-called instrument cluster (instrument panel) mounted on an instrument panel. Currently, such information can be displayed on a windshield above the instrument panel using a head-up display (for example, Japanese Patent Application Laid-Open No. Hei 09-15555). [0003] In the head-up display device described in JP-A-09-15555, the driver sees a virtual image of the displayed image reflected on the windshield. Accordingly, the driver perceives the displayed image in a space with respect to the windshield and its opposite side, ie, on the outside of the vehicle. [0004] Typically, the po...
