Array type widescreen head up display device

A head-up display device, in particular to an array type wide-screen head-up display device capable of simultaneously displaying multiple images and a panoramic image.

In an increasingly complex driving environment, in order to ensure driving safety, drivers need to be aware of various information related to vehicle conditions, such as vehicle speed, engine speed, water temperature, gear position and fuel quantity. In the general car structure, the above information is displayed on one dashboard. In order to maximize the driver's front view, the instrument panel is usually placed under the windshield. During the driving process, the driver usually needs to know the changes of the surrounding road conditions through the windshield. At this time, most of the binocular lines of sight are facing forward. If you need to know the message such as the speed of the car, the driver must look down and turn the line of sight to the dashboard set under the windshield. The shift of this line of sight often causes the driver to be distracted in an instant, which leads to the occurrence of dangerous driving accidents.

By setting the first image source 111, the second image source 112, and the third image source 113, three images can be provided, and the three images are each in a real image state. The three images can be independently distinct or combined to form a complete panoramic image.

In an example, an image source may be combined with a plurality of mirrors to generate three images, and the form thereof is not limited.

After the three images are generated, the three images are respectively reflected by the three first mirrors 120 to the three light diffusing elements 130. Through the light diffusing element 130, the brightness and contrast of the three images can be adjusted separately according to the change of the brightness of the ambient light of the external environment, thereby making the final imaging clearer.

The magnifier array 140 is configured to receive the three-light diffusing element 130 Three images, and the three images are magnified into a virtual image state. The magnifying glass array 140 is configured by sequentially arranging the first magnifying glass 141, the second magnifying glass 142, and the third magnifying glass 143. The relative relationship between the magnifying glass array 141, the magnifying glasses 141, 142 and 143 and the imaging optical path of the three images is an important technical feature of the present invention, which is described in detail in the subsequent 3A, 3B and 4A, 4B drawings.

The adjustable display screen 160 receives the magnification through the magnifying glass array 140 After the image, the three magnified images are presented to a driver. At this time, as mentioned above, the three images displayed by the first image source 111, the second image source 112, and the third image source 113 are independently different or combined to form a complete panoramic image, and thus, through the magnifying glass. After the array 140 is enlarged and converted into a virtual image state, the images may be independently different or combined to form a complete panoramic image. Thereby, the array type wide screen head-up display device 100 of the present invention has various application modes.

The road's road conditions search results, while the remaining images present a car-side live image. Secondly, the driver can see the complete car side view image composed of three images through the adjustable display screen 160 on the windshield.

Please refer to FIG. 3A and FIG. 3B at the same time. FIG. 3A is a diagram of the array type widescreen head-up display device 100 of FIG. 2, which uses two image sources (first image source 111, third image source 113) and two magnifiers. A state diagram of one of the first magnifier 141 and the third magnifier 143 is implemented. FIG. 3B is a diagram of the array type widescreen head-up display device 100 of FIG. 1 , using two image sources (first Another embodiment of the image source 111 and the third image source 113) is combined with a magnifying glass (the first magnifying glass 141 and the third magnifying glass 143). For convenience of explanation, in FIGS. 3A and 3B, several elements will be omitted to better understand the features of the present invention.

In the array type widescreen head-up display device 100 of the present invention, the magnifying glass array 140 may be composed of two magnifying glasses (the first magnifying glass 141, the third magnifying glass 143) or three magnifying glasses (the first magnifying glass 141, the second magnifying glass 142, and the third magnifying glass 143). There is no special limit on the number, and a magnifying glass of two or more quantities is acceptable.

In the 3A and 3B, the first image source 111 and the third image source 113 are used to generate two images, which are transmitted through the first magnifying glass 141 and the third magnifying glass 143 and then enlarged and presented to the driver's eyes. Through the use of the two magnifying glasses (the first magnifying glass 141 and the third magnifying glass 143), the user can see the two-phase image or the complete panoramic image composed of the two images on the windshield. Therefore, the combination of the magnifying glass array 140 and the two image sources (the first image source 111 and the third image source 113) is quite important.

In FIG. 3A, the first image source 111 and the third image source 113 are separated from each other by a gap D, and the first magnifying glass 141 and the third magnifying glass 143 are oppositely disposed by the first image source 111 and the third image source 113. The imaging of the two images is on the optical path. Different from the conventional method, the first image source 111 and the third image source 113 are combined to form a gap D, and the imaging optical path of the two images generated by the first imaging source 111 and the third magnifying glass 143 corresponding thereto are formed. The optical axis forms an off-axis state (Off-Axis). Thereby, after the two images are enlarged by the first magnifying glass 141 and the third magnifying glass 143, the two images are Like the overlap and form a pair of eyes, both the Exit Pupil P and the window W (in Figure 3A, the size of the exit pupil P is exactly equal to the size of the window W). In FIG. 3B, a larger window W can be obtained by adjusting the gap D and the arrangement between the optical elements (such as the magnifying glasses in the magnifying glass array 140), so that compared to FIG. 3A, FIG. 3B Both eyes can be viewed in a wide range of images. Since the visible range of the general human eye has its limitation, the diameter of the exit pupil P needs to be greater than or equal to 65 mm, so that the driver can simultaneously see the two images presented on the windshield.

Please refer to FIG. 4A and FIG. 4B simultaneously. FIG. 4A is a diagram of the array type widescreen head-up display device 100 of FIG. 2, using three image sources (the first image source 111, the second image source 112, and the third image). The source 113) implements a state diagram in conjunction with one of the three magnifiers (the first magnifier 141, the second magnifier 142, and the third magnifier 143). FIG. 4B is a diagram of the array type widescreen head-up display device 100 of FIG. 2, which uses three image sources (the first image source 111, the second image source 112, and the third image source 113) to match the three magnifying glasses (the first magnifying glass 141). Another implementation state diagram of the second magnifying glass 142 and the third magnifying glass 143). In FIGS. 4A and 4B, the first image source 111, the second image source 112, and the third image source 113 are used to generate three images, which are transmitted through the first magnifying glass 141, the second magnifying glass 142, and the third image. After the magnifying glass 143 is enlarged and converted into a virtual image state, it is presented to the driver's eyes. The user can see three independent images or a complete panoramic image composed of three images on the windshield.

Different from the foregoing FIG. 3A and FIG. 3B, since the number of magnifiers of the magnifying glass array 140 is an odd number, the imaging optical path of the image generated by the second image source 112 overlaps with the optical axis of the second magnifying glass 142. (On-Axis), and the imaging optical paths of the images generated by the first image source 111 and the third image source 113 respectively form an off-axis state (Off) of the optical axes of the corresponding first magnifier 141 and third magnifier 143 -Axis). Thereby, the three images can be enlarged and converted into a virtual image state through the first magnifying glass 141 and the third magnifying glass 143, and the three images overlap and form a pair of eyes simultaneously visible as the 瞳P and the window W (in FIG. 4A,瞳P size is exactly equal to the window W size).

In FIG. 4A, the first image source 111, the second image source 112, and the third image source 113 are separated from each other by a gap D. As described above, as the size of the gap D is different and the arrangement between the optical elements is different, different window W can be obtained, whereby the binocular viewing range can be adjusted. In Fig. 4B, since the gap D is changed, the window W is made larger, so that the binocular viewing range is large. Alternatively, the size of the window W can be adjusted by adjusting the configuration of each magnifier in the magnifying glass array 140. When the diameter of the exit pupil P is greater than or equal to 65 mm, the driver can see three images at the same time, and the binocular field of view is larger than the setting mode in FIG. 3A.

In the actual application of the array type widescreen head-up display device 100 of FIG. 2, a part of the optical components of the array type wide-screen head-up display device 100 can be assembled by a casing (not shown). Through an exposed adjustable display (not shown), the image can be projected at an appropriate angle to the driver by controlling the displacement. The above displacement can be various ways such as tilting, translation or rotation.

In order to form a wide-screen image to provide a variety of information to the driver, in addition to the multiple images produced by the multiple magnifying glasses combined with the image source as described above, the present invention Ming also offers another head-up display that can form a widescreen image.

Through the first relay imaging lens 221 and the second relay imaging lens 223, the two images can be independently imaged. In addition, two second light diffusing elements 227 may be further provided to enhance the brightness and contrast of the two images.

In Fig. 7, three shutters (first shutter S1, second shutter S2, and third shutter S3) are used to switch the three images generated by the display image source 210. At this time, the time domains R, C, and L in which the three images are spaced apart from each other are 1/180 second. That is, the display of the three images differs from each other by 1/180 second. Then, by switching the first shutter S1, the second shutter S2, and the third shutter S3 in synchronization with the time domain of 1/180 second, the presentation of the three images can be seen at the same time.

The above method of using the visual persistence to form two images or three images can also be combined with the magnifying glass array 230 to achieve better results. The array type widescreen head-up display device 200 shown in FIG. 5 uses three shutters (a first shutter S1, a second shutter S2, a third shutter S3) and three magnifying glasses (231, a second magnifying glass 232, and a third). The magnifying glass 233) achieves the effect of displaying multiple images.

When the array type widescreen head-up display device 200 of FIG. 5 is actually applied, a part of the optical components of the array type wide-screen head-up display device 200 can be assembled by a casing (not shown). Most of the optical components are assembled into the housing, and an exposed adjustable display screen (not shown) can be used to control the displacement to present the image to the driver at an appropriate angle. The above displacement can be various ways such as tilting, translation or rotation.

In summary, the present invention discloses an array type widescreen head-up display device. A variety of different independent images or a complete panoramic image can be displayed simultaneously using the visual persistence effect or through the settings of the magnifying glass array. Moreover, through the different configurations of the magnifier array, the window size can also be modulated. In this way, the driver can see the wide-screen undistorted multiple images on the windshield while viewing the surrounding environment through the windshield, and is more traditional. The head-up display has a larger field of view, allowing you to learn more complex and diverse messages while driving, avoiding looking down at the dashboard and increasing the safety and convenience of driving.
