Description

Technical Field

[0001] This invention relates to the field of live-fire combat training technology, specifically to a monocular display. Background Technology

[0002] With the widespread application of live-fire combat training systems at training bases across the military, training equipment for some simulated weapons needs to be lightweight and miniaturized to meet the requirements of reducing the size exposed during actual simulations and facilitating portability. As training requirements increase and new warfare models evolve, new display devices have become indispensable components in weapon simulators. Among these, a monocular display is a device that provides display functionality to only one eye. It is typically designed as a head-mounted device or integrated into a specific device, used to project images or information directly in front of one of the user's eyes while maintaining the normal field of vision of the other eye.

[0003] Existing monocular displays are typically large in size, and due to the integration of multiple functional devices, the motherboard has low heat dissipation efficiency. Overheating of the motherboard can reduce the operating performance of the device and even lead to hardware damage. Therefore, providing a monocular display with high integration, small size, and high motherboard heat dissipation efficiency is an urgent problem to be solved. Summary of the Invention

[0004] Purpose of the invention: The purpose of this invention is to address the shortcomings of existing technologies, such as excessively large device size and poor heat dissipation performance, by providing a monocular display that not only integrates the required components and reduces the size through structural design, but also improves the heat dissipation performance of the motherboard through the design of heat dissipation silicon sheets.

[0005] Technical solution: The present invention provides a monocular display, including an eyepiece, a display screen, and a processing system. The eyepiece is fixedly connected to the front end of the main control compartment by fastening screws, and a rear cover is fixedly connected to the rear end of the main control compartment by countersunk screws. The main control compartment is a hollow cylinder, and the display screen and processing system are integrated inside the cylinder. The processing system includes a display driver board, and a heat dissipation silicon fin is provided on the back of the display driver board.

[0006] This invention transmits image signals via the MICRO HDMI interface at the rear of the display driver board, with the built-in display chip handling signal reception and conversion. The specific workflow consists of three steps: First, the display chip converts the input analog image signal into a digital signal and performs resolution adaptation processing; second, the driver board converts the processed digital signal into a MIPI interface protocol signal; finally, the display screen receives the protocol signal and drives the pixels, forming a visible image through the backlight module. The eyepiece system uses an aspherical lens group to optically correct the image on the display screen, converting divergent light into parallel light output, providing the user with a magnified and distortion-free virtual image. A heat dissipation silicon sheet distributes the heat generated by the driver board evenly to the main control compartment's metal casing through thermal conduction, achieving passive heat dissipation.

[0007] Furthermore, the eyepiece is fitted with a protective goggle cover, and the eyepiece, protective goggle cover, and display screen are coaxially mounted. This three-element coaxial mounting can control optical axis deviation and effectively eliminate eccentric aberration.

[0008] Furthermore, the front end of the main control compartment is provided with a sealing groove for placing an O-ring. When the eyepiece is fixedly connected to the front end of the main control compartment, the O-ring plays a role in sealing and waterproofing.

[0009] Furthermore, the display screen and processing system are integrated inside the main control compartment via a motherboard mounting bracket. Due to the unique motherboard mounting bracket structure, the display screen and processing system can be highly integrated, reducing the overall size of the device.

[0010] Furthermore, the motherboard mounting bracket includes a motherboard adapted to the size of the display driver board. A display screen connection plate is fixed to the front end of the motherboard, and a rear cover connection plate is fixed to the rear end of the motherboard. The rear cover connection plate is inserted into a corresponding through hole on the rear cover and is detachably connected to the rear cover. The side of the motherboard mounting bracket away from the display driver board 7 has a set of serrated structures.

[0011] Furthermore, a heat dissipation fin is provided on the back of the display screen. The heat dissipation fin can be a commercially available JEYI thermal conductive silicone pad or thermal conductive fin.

[0012] Furthermore, a set of mounting holes is provided on the outer wall of the main control compartment. The mounting holes can be fixed to different clamps by bolts. The clamps can integrate the monocular display of the present invention into, for example, a soldier's combat helmet to serve as a soldier's night vision device, or it can be used as a field of view observation on other weapon simulation terminals to meet the user's needs.

[0013] Furthermore, the eyepiece is a 15x eyepiece, and can be adjusted to suit the user's visual condition by adjusting the interpupillary distance. The eyepiece can be a commercially available diffractive optics or a product from Lizhi Zhengzhong Electronics.

[0014] Beneficial effects: Compared with the prior art, the advantages of the present invention are: (1) The present invention is designed with a main control compartment and a motherboard mounting bracket. The two work together to highly integrate the display screen and the display driver board into the main control compartment, greatly reducing the product size and making it suitable for different scenario requirements; at the same time, the design of heat dissipation silicon sheet attached to the display screen and the display driver board is used for heat dissipation to ensure the operating performance of the processing system.

[0015] (2) The present invention uses the Micro HDMI interface in the prior art. The system is powered by the built-in VCC of the Micro HDMI interface, eliminating the need for an external USB interface for additional VCC power supply. The use of the Micro HDMI interface makes the monocular structure smaller and lighter. Attached Figure Description

The user observes the image displayed on the display screen through the eyepiece 2. In addition, a goggle cover 1 is fitted onto the eyepiece 2, and the eyepiece 2, goggle cover 1, and display screen are coaxially mounted. The front end of the main control chamber 5 is provided with a sealing groove for placing an O-ring 3. When the eyepiece 2 is fixedly connected to the front end of the main control chamber 5, the O-ring 3 serves to seal and waterproof the device. A set of mounting holes 13 are provided on the outer wall of the main control chamber 5. The mounting holes 13 can be used to fix the device to different clamps using bolts. The eyepiece 2 is a 15x eyepiece, and its interpupillary distance can be adjusted to suit the user's visual acuity.

[0023] In this embodiment, the display screen 12 is a SONY 0.71-inch display screen, the processing system is a SONY 0.71 HDMI driver board, the eyepiece is a commercially available diffractive optical eyepiece, the heat dissipation silicon sheet is a commercially available JEYI thermal conductive silicone sheet, and the MICROHDMI is XUNPU's HDMI-D.

[0024] The installation method in this embodiment:

Figure 3 and Figure 4 The whole as shown.

[0026] The working principle of this embodiment is as follows:

[0027] 1. Signal Input and Processing

[0028] An external camera transmits image signals to the display driver board 7 via an HDMI interface. The display chip (such as a GPU or a dedicated image processor) built into the display driver board 7 decodes the HDMI digital signal and converts it into an electrical signal that the display screen 12 can recognize. The driver board automatically adapts the output mode according to the specifications of the display screen 12 (such as a SONY 0.71-inch screen with a resolution of 1280×720) to ensure that the image is not stretched or compressed.

[0029] 2. Image display and optical magnification

[0030] The processed electrical signal drives the display screen 12 to display the original image. The eyepiece 2 magnifies the tiny pixels of the display screen 12 by 15 times through the lens group (for example, a 0.71-inch screen is equivalent to a 10.65-inch visual effect). The interpupillary distance of the eyepiece 2 is adjusted by a mechanical adjustment mechanism (such as a knob or slide rail) (the range is usually 55 to 75 mm) to adapt to the interpupillary distance of different users. At the same time, it supports diopter adjustment (such as -5D to +2D) to adapt to myopic / hyperopic users.
