[0022] Example 1

[0023] Please see Figures 1-5 A small-pitch LED smart interactive blackboard, comprising:

[0024] Support component 1 includes several small-pitch boxes 11, which are interconnected. A top outer frame 12 is connected to the top of each small-pitch box 11, and a top inner frame 13 is also installed on the top outer frame 12. A bottom outer frame 14 is installed on the bottom of each small-pitch box 11, and a bottom inner frame 15 is also installed on the bottom outer frame 14. A display component 2 is installed on the front end of each small-pitch box 11, and an infrared touch component 3 is installed inside the top inner frame 13 and the bottom inner frame 15.

[0025] The small-pitch cabinets 11 are interconnected and fixed to form a complete screen. Bolts or other structures that can serve the same purpose can be used to replace the small-pitch cabinets 11. Each small-pitch cabinet 11 has a PCB for controlling the display. Each small-pitch cabinet 11 is equipped with a part of the display screen. Multiple small-pitch cabinets 11 are combined to form a large screen. Each small-pitch cabinet 11 can control the screen it is responsible for, thus enabling the individual control of a part of the screen to turn off. The top inner frame 13, the bottom inner frame 15, and the small-pitch cabinets 11 are all provided with mounting holes for connecting and fixing the frame to the small-pitch cabinets 11. The display component 2 is used to display content. The infrared touch component 3 uses the method of emitting infrared light to form an infrared detection network to achieve touch control. It can directly replace the traditional blackboard and no longer needs to consider the problem of splicing LCD and traditional blackboard. Instead, the appropriate number and size of small-pitch cabinets 11 are installed according to the needs to form a smart blackboard.

[0026] See Figure 4 The display component 2 includes several small-pitch LED screens. The number and size of the small-pitch LED screens are adapted to the small-pitch cabinet 11. The small-pitch LED screens are fixedly connected to the small-pitch cabinet 11. Each small-pitch LED screen is fixedly connected to the small-pitch cabinet 11, and adjacent small-pitch LED screens are bonded to each other.

[0027] The inner wall of the top inner frame 13 has a slot, into which several translucent glass pieces 22 are inserted. At least three translucent glass pieces 22 are provided. After the small-pitch cabinet 11, small-pitch LED screen 21, top inner frame 13 and bottom inner frame 15 are installed, the translucent glass pieces 22 are inserted into the slot from both sides of the inner frame, from left to right, until the translucent glass pieces 22 completely cover all small-pitch LED screens 21. By setting multiple translucent glass pieces 22, the entire screen is divided into multiple parts, so that certain parts can be controlled to be off or on independently. Teachers can write on the blackboard in the off part and display content in the on part. The translucent glass pieces 22 can also serve as a blackboard. After the small-pitch LED screen 21 is off, writing can be done directly on the translucent glass pieces 22.

[0028] See Figure 5A device cavity is provided between the bottom inner frame 15 and the bottom outer frame 14. The device cavity houses the controller 16 and the speaker 17. The controller 16 is electrically connected to the small-pitch LED screen 21, the speaker 17, and the infrared touch component 3. After the bottom inner frame 15 is installed, the bottom outer frame 14 can be installed on the bottom inner frame 15. The bottom outer frame 14 and the top outer frame 12 can be fixed to the inner frame by bolts, snap-fit, or magnetic connection. By setting the controller 16, which is electrically connected to each small-pitch LED screen 21, the display content of the screen can be adjusted. Several small-pitch LED screens 21 can also be grouped together to reduce the difficulty of control. The speaker 17 is used to play sound. The controller 16 reads the data of the infrared touch component 3 to determine the touch position.

[0029] See Figure 4 The top inner frame 13 is also provided with an upper receiving cavity. The infrared touch component 3 includes an upper infrared touch lamp 31 disposed in the upper receiving cavity, and an upper infrared touch light-transmitting strip 33 is provided at the opening of the upper receiving cavity.

[0030] See Figure 5 The bottom inner frame 15 is provided with the same lower receiving cavity. The infrared touch component 3 also includes a lower infrared touch lamp 32 disposed in the lower receiving cavity. The opening of the lower receiving cavity is provided with a lower infrared touch light-transmitting strip 34.

[0031] The upper infrared touch lamp 31 and the lower infrared touch lamp 32 are aligned with each other and emit infrared light together to form an infrared detection network. Any touch object can change the infrared light on the touch point to realize touch screen operation. The upper infrared touch light-transmitting strip 33 and the lower infrared touch light-transmitting strip 34 are used to protect the infrared touch lamps and also seal the receiving cavity to prevent foreign objects from falling into the receiving cavity.
