Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0017] like Figure 1-8 As shown in the figure, an optical touch module for mounting on a flat panel display screen is provided in this embodiment of the present invention, comprising: at least two touch modules 1, each touch module 1 being communicatively connected to the flat panel display screen 3 via a connecting component 2, and the touch modules 1 being communicatively connected to each other via the connecting component 2; The connecting component 2 is configured as a spring-loaded connector 21 or a wire connector 22 according to the different structures of the flat panel display screen 3, wherein: The spring pin connector 21 is used to match and connect to a first type of flat panel display screen, which has at least two contact adapter boards 31 installed inside, and the contact adapter boards 31 are connected to each other by a high-speed signal line 32; the wire connector 22 is used to match and connect to a second type of flat panel display screen, which does not have contact adapter boards 31 installed inside. Each touch module 1 includes a housing 11, an optical module 12, and a main control board 13; An optical module 12 is fixedly mounted on the outer wall of the housing 11, and the optical module 12 is connected to the main control board 13; The main control board 13 is housed inside the housing 11, and the main control board 13 is connected to the flat panel display screen 3 via the connecting component 2; Each main control board 13 is connected to the other via a connecting component 2; The housing 11 is provided with an assembly component 14 for connecting to the flat panel display 3.

[0018] Obviously, the optical touch module provided in this embodiment of the present invention, which is assembled on the flat panel display screen 3, integrates the optical module 12 and the main control board 13 through the housing 11 to form a modular structure. In use, it is very convenient and quick to install the optical touch module with different connection component types according to the different structure types of the flat panel display screen. In this type of flat panel display 3, where at least two contact adapter boards 31 are installed within the display panel 3, and the contact adapter boards 31 are connected via high-speed signal lines 32 (FFC), the optical touch module can be installed by simply inserting it into the contact adapter board 31 via the spring-loaded connector 21. (At this time, the two optical touch modules communicate with each other via high-speed signal lines, and the optical touch modules communicate with the flat panel display via spring-loaded connectors and contact adapter boards.) When the flat panel display 3 does not have a contact adapter plate, this type of flat panel display 3 can be installed by simply connecting the two optical touch modules with a data cable, such as a Micro-HDMI cable. Each optical touch module can be connected to the communication interface of the flat panel display 3 with a data cable, such as a USB interface or a Type-C interface. The structure can be installed by fixing it to the flat panel display screen 3 using assembly components such as bolts and bolt holes provided on the optical touch module housing 11.

[0019] After completing the above communication and structural installations, the flat panel display 3 can be used as a touch screen. For ease of understanding, a simple illustrative explanation of its principle is provided below: In this embodiment, the two optical touch modules are spaced apart and mounted at the two lower corners of the flat panel display screen 3. However, in actual assembly, they are not limited to this location. The two optical touch modules can be mounted at the two upper corners, the two left corners, or the two right corners of the flat panel display screen 3. The specific mounting and fixing can be done as needed. Two optical modules 12 simultaneously capture touch objects, such as fingers, on the flat panel display 3 and send the captured images of the touch objects to the main control board 13. The main control board 13 recognizes the images and calculates the touch coordinates using the principle of triangle positioning. The touch coordinates are then sent to the flat panel display 3, and the controller of the flat panel display 3 controls the display content of the flat panel display 3 based on the touch coordinates.

[0020] In some embodiments, the flat panel display 3 can be a television screen, especially suitable for Skyworth televisions.

[0021] In some embodiments, the housing 11 includes an upper cover 111 and a lower box 112, with the upper cover 111 fixedly disposed on the top of the lower box 112; The lower box 112 can be a cuboid structure. The length of the lower box 112 can be set as needed. The width of the lower box 112 matches the thickness of the flat panel display 3 to facilitate installation and improve the product's aesthetics and user experience. The lower box 112 has an inwardly recessed mounting groove on its front side, the structure of which matches the optical module 12. A main control board 13 is fixedly installed inside the lower box 112, and the main control board 13 is connected to the connecting assembly 2. Specifically: When the connecting component 2 is a spring pin connector 21, the main control board 13 is connected to one end of the spring pin connector 21, and the other end of the spring pin connector 21 extends to the outside of the upper cover 111. When the connecting component 2 is a wire connector 22, the main control board 13 is connected to one end of the wire connector 22, and the other end of the wire connector 22 extends to the outside of the lower box 112.

[0022] In addition, in this embodiment, the assembly component 14 provided on the housing 11 consists of bolts and bolt holes, which are used to achieve a fixed connection with the flat panel display screen 3.

[0023] In some embodiments, the optical module 12 is configured as a triangular structure, which not only adapts to the structural characteristics of the flat panel display 3, but also improves the overall aesthetics of the device and the user experience, and can maximize the field of view for image capture.

[0024] In this embodiment, the optical module 12 includes a mounting part and an image acquisition part. The mounting part is disposed in the mounting slot, and the image acquisition part is located outside the mounting slot. The image acquisition part is used to acquire images of touch objects on the flat panel display screen 3. The image acquisition part can be an infrared camera.

[0025] Obviously, those skilled in the art should understand that the modules or steps of the above-described embodiments of the present invention can be implemented using general-purpose computing devices. They can be centralized on a single computing device or distributed across a network of multiple computing devices. Optionally, they can be implemented using computer-executable program code, thereby storing them in a storage device for execution by a computing device. In some cases, the steps shown or described can be performed in a different order than those presented herein, or they can be fabricated as separate integrated circuit modules, or multiple modules or steps can be fabricated as a single integrated circuit module.
