Problems solved by technology

[0004] However, in actual use, often due to insufficient reflectivity of the semi-transparent mirror or film or strong background light in front, the contrast of the navigation information is significantly reduced, resulting in unclear pictures and other problems. In order to see the navigation information more clearly, the eyes stay on the navigation screen for a longer time, which may cause danger on the road

Embodiment 1

[0023] see figure 2 and image 3 , figure 2 It is a schematic structural diagram of an embodiment of the vehicle display device in the embodiment of the present invention; image 3 yes figure 2 The working principle diagram of the vehicle display device in the embodiment; Figure 4 yes figure 2 In the embodiment, the scene seen by the driver from the front windshield and the display device. Such as figure 2 As shown, the vehicle display device 100 includes a camera device 110 , a picture combining device (not shown in the figure) and a display device 120 .

[0024] Such as Figure 2-Figure 4 As shown, the driver sees the scene 10 ahead of the car through the front windshield 2, and the camera device 110 is used to photograph the scene ahead of the car. The picture combining device is used to acquire the target shooting picture 20 of the camera device (that is, the scene in front of the car covered by the display device), acquire the navigation picture 30 , and ove...

Embodiment 2

[0030] see Figure 5 , Figure 5 It is a schematic structural diagram of another embodiment of the vehicle display device in the embodiment of the present invention. Such as Figure 5 As shown, the vehicle display device 500 includes a camera device 510 , a picture combining device (not shown in the figure) and a display device 520 .

[0031] The difference between this embodiment and Embodiment 1 is:

[0032] In this embodiment, the display device 520 is a projection display device. The projection display device may adopt various projection technologies, such as liquid crystal display (LCD, Liquid Crystal Display) projection technology, digital light path processor (DLP, Digital Light Processor) projection technology. Since the projection screen does not have a frame like that of a liquid crystal display device, there is no frame between the combined picture on the projection screen and the front view of the car in the front windshield, so that the picture image and the f...

Abstract

The embodiment of the invention discloses vehicle-used display equipment. The vehicle-used display equipment comprises a camera shooting device, a picture combining device and a display device, wherein the camera shooting device is used for shooting scenes in front of an automobile; the picture combining device is used for obtaining target shooting pictures of the camera shooting device, obtaining navigation pictures of which underpainting is transparent, and overlapping the navigation pictures on the target shooting pictures to form combined pictures; the display device is located behind front windshield glass of the automobile, and is used for displaying the combined pictures; and the combined pictures are jointed with the scenes in front of the automobile in the front windshield glass. Through the adoption of the vehicle-used display equipment disclosed by the embodiment of the invention, a driver not only can see navigation information on the display device, but also can see the whole scenes in front of the automobile from the front windshield glass and the display device, so that the problem that in the prior art, the scenes are sheltered is avoided; and besides, light rays emitted by the display device are most effectively used, and the image contrast ratio is improved, so that the problem that the navigation pictures are unclear caused by a transflective mode is avoided, and the driver can easily see the navigation pictures clearly.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a display device for a vehicle. Background technique [0002] In order to improve the convenience of driving, car navigation has become one of the devices selected by most drivers, so as to obtain direction guidance, vehicle speed, maps and other information while driving. [0003] Such as figure 1 As shown, the traditional car navigation device all is to set up the LCD screen 1 in front of the driver, so that the driver can obtain navigation information from the LCD screen. However, during driving, the driver needs to carefully watch the scene ahead of the car through the front windshield 2, and obviously the navigation device obscures the scene to some extent. The blocking of the driver's driving line of sight often leads to the occurrence of car accidents. Therefore, although the use of traditional car navigation devices can bring convenience, it also increases the pos...
