1. Field of the Disclosure
The present disclosure generally relates to display systems, and particularly to a display system providing a stereo image for a driver in a vehicle, and a vehicle utilizing the display system.
2. Description of Related Art
With developments in automotive technology, performance, aerodynamics, and safety have been geared to meet desires of consumers. Rearview mirrors used in automobiles are an important feature, allowing the driver to see the area to the rear of vehicle through the back windows.
However, many rearview mirrors are difficult to see and provide only limited vision for the driver, leaving much room for improvement.
What is needed, therefore, is an improved display system which can overcome the limitations described.
Many aspects of the disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present display system. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
A display system for use in a vehicle is disclosed. Referring to
The vehicle 100 includes a compartment 110, a windshield 130, a rear window 150 and a seat 170 adjacent to the windshield 130. The image capture module 21 is mounted on an inner ceiling of the compartment 110. Generally, the image capture module 21 can be a camera module facing the rear window 150. The camera module 21 includes a lens 21A and an image sensor 21B. Light from objects (such as other vehicles) to the rear of compartment 110 enters through the rear window 150 and the lens 21A to reach image sensor 21B. The image sensor 21B detects the light and forms a corresponding image and generates a detected signal of the image, provided to the camera module 21. Image sensor 21B can be a charge-coupled system (CCD) or a complementary metal oxide semiconductor system (CMOS).
The stereoscopic projection device 22 is mounted on the inner ceiling of the body 110 adjacent to the windshield 130, and is electrically connected to the image capture module 21, receiving the detected signal therefrom. The projecting panel 23 is positioned above the seat 170 of the vehicle 100 facing the stereoscopic projection device 22. Here, the projecting panel 23 is a white board disposed between the windshield 130 and the stereoscopic projection device 22. The stereoscopic projection device 22 projects a stereo image of the signal to the projecting panel 23 upon receipt of same. A driver M on the seat 170 can accurately monitor the area and conditions to the rear of vehicle 100. The lens 21A can be a wide-angle lens providing a wider field of traffic.
A vehicle 100 employing the first embodiment 20 of the display system is also disclosed, as shown in
The first display system module 20 includes a first image capture module 21, a first stereoscopic projection device 22 and a first projecting panel 23 facing the stereoscopic projection device 22. The first stereoscopic projection device 22 is mounted on an inner ceiling of the compartment 210. The first projecting panel 23 is positioned adjacent to the windshield 230 and above a drive's seat 270. The first image capture module 21 is mounted on an outer top of the compartment 210 providing a wider field of the traffic for the driver M.
The two second display system modules 30 each include a second image capture module 31, a second stereoscopic projection device 32 and a second projecting panel 33 facing the second stereoscopic projection device 32. The two second display system modules 30 are arranged on two lateral anterior sides 210A, 210B of the compartment 210. The two second image capture modules 31 capture image of objects on the road at two posterior lateral sides of the compartment 210. The two second projecting panels 33 are positioned at two lateral sides of the driver's seat respectively facing the driver M. The driver M can view road conditions on posterior lateral sides of the compartment 210 through the two second projecting panels 33.
A vehicle 200 employing the first embodiment 20 of the display system is also disclosed, as shown in
As shown, the first image capture module 21 can be arranged at the rear 280 of the compartment 210, provided that the first image capture module 21 can capture a sufficient range of traffic to the rear of compartment 210 than on the outer top of the compartment 210. Accordingly, arrangement of the first image capture module 21 on the compartment 210 can be varied while remaining well within the scope of the disclosure.
It is believed that the present disclosure and its advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary preferred embodiments of the disclosure.
