[0006] The control system is used to generate graphical data and UI interface data;
[0007] The graphics card is used to receive the graphics data and process it into graphics signals, and to receive UI interface data and form UI interface signals.
[0008] The display is used to receive the graphic signal and convert it into a light signal to form an image. The optical system is used to magnify the image generated by the display and present it as a virtual image at a position with a virtual image distance of not less than 3 meters.
[0009] The touch screen is used to receive the UI interface signal and convert it into a light signal to form a UI interface image. The touch screen is used to interact with the control system by touching the area corresponding to the UI interface image, so as to control the graphic data generated by the control system.

[0030] like Figure 1As shown, this utility model embodiment provides a remote image display interactive control device, including a control system 1, a graphics card, a display 2, an optical system 3, and a touch screen 4;
[0031] Control system 1 is used to generate data for graphical data and UI interface data;
[0032] The graphics card is used to receive graphics data and process it into graphics signals, and to receive UI interface data and process it into UI interface signals.
[0033] The image display 2 is used to receive graphic signals and convert them into light signals to form an image. The optical system 3 is used to magnify the image generated by the image display 2 and present it as a virtual image at a position with an exit pupil distance of not less than 3 meters.
[0034] The touch screen 4 is used to receive UI interface signals and convert them into light signals to form a UI interface image 41. The touch screen 4 is used to interact with the control system 1 by touching the area corresponding to the UI interface image 41, so as to control the graphic data generated by the control system 1.
[0035] In this embodiment, to address the problem that the virtual image 5 reflected by the optical system 3 of the far-view display device cannot be projected onto the physical screen, thus preventing touch interaction, a touch screen is added. By touching the area corresponding to the UI interface image on the touch screen, the control system 1 can be operated, thereby controlling the image output from the control system 1 to the display 2. During touch interaction, operations can be performed through the UI interface of the touch screen 4, and the operation process and results can be observed through the virtual image. After completing the operation, the large-screen virtual image 5 output by the display 2 and the optical system 3 can be used to view the image. This setup allows for convenient human-computer interaction via the touch screen.
[0036] In some embodiments of this utility model, both the display 2 and the touch screen 4 include a display, which is a liquid crystal display or an organic light-emitting diode display.
[0037] In some embodiments of this utility model, the display 2 and the touch screen 4 are connected to the control system 1 via HDMI, VGA or DisplayPort respectively.
[0038] In some embodiments of this utility model, the control system 1 is a computer, an embedded system, or a microcontroller.
[0039] In some embodiments of this utility model, the operating system of the control system 1 is Windows, Linux or macOS.
[0040] In some embodiments of this utility model, the touch screen 4 is provided with a switch, which is used to turn the touch screen off and on.
[0041] In some embodiments of this utility model, a touch control circuit electrically connected to the touch screen is also included, and the touch control circuit is connected to the control system 1.
[0042] In some embodiments of this utility model, the touch screen is selected from any one of resistive, capacitive, ultrasonic, and infrared types.
[0043] In some embodiments of this invention, the touchscreen 4 is also used to receive graphic signals and convert them into light signals to form an image. This image is the display image 42, and both the image output by the display 2 and the display image 42 originate from the graphic signals of the control system. Therefore, the content is the same, and the control process and results can be viewed on the display image 42 through the UI interface.
[0044] In some embodiments of this utility model, the touch screen uses a display screen with an always-on display function. The touch screen is only lit when there is an update to the UI interface signal, and is in an always-on state at other times.
[0045] In some embodiments of this invention, the UI interface image and the display image can be merged and simultaneously displayed on the display 2 and the touch screen 4. In this case, touch control is achieved through the touch screen 4, and the display images on both the display 2 and the touch screen 4 are changed simultaneously. Therefore, this application does not intentionally avoid displaying the UI interface image used for touch control on the screen of the display 2.
[0046] like Figure 2 As shown, this application also provides a far-image display device, including a housing 10 and a far-image display interactive control device. The control system 1, graphics card, display 2 and optical system 3 of the far-image display interactive control device are all installed inside the housing 10 by fasteners. Only the touch screen 4 is installed on the side of the housing 10 facing the exit pupil. In addition, a viewing window 11 is provided on the housing 10. The housing 10 can be fixed and its height and tilt angle can be adjusted by a bracket.
[0047] like Figure 3 In the illustrated embodiment, the optical system 3 of the far-image display interactive control device includes an image source IMA, a planar beam splitter L1, a curved reflector L2, and a lens L3. The image source IMA is the light-emitting surface of the display 2. Light emitted from the image source IMA is refracted by the lens L4 and then directed to the planar beam splitter L1. The planar beam splitter L1 guides the light to the curved reflector L2, where it is reflected by the concave reflector L2. The planar beam splitter L1 then guides the light to the exit pupil position, where it is imaged in the eye of the viewer at the exit pupil position STP, forming a virtual image. The planar beam splitter L1 can be used directly as the viewing window 11 of the far-image display device, or the viewing window 11 can be set on the outside of the planar beam splitter L1.

It should be understood that this illustration does not constitute a limitation on the far-viewing display device. Vehicle-mounted far-viewing display devices using similar optical schemes and structures can also be controlled using the aforementioned far-viewing display interactive control device.
[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
