Problems solved by technology

[0003] However, the existing technical solutions require both the smart pen and the display device to have a built-in wifi module, and the price and cost are high. Because the wifi frequency band is used, it is greatly affected by radio frequency interference, so that the display device cannot accurately execute the control commands sent by the smart pen.
At the same time, the smart pen based on wifi can realize the signal connection as long as it is in the connection state, and there is no accurate judgment on the distance between the devices

Embodiment 1

[0056] figure 2 It is a schematic structural diagram of an interactive device provided in Embodiment 1 of the present invention, refer to figure 2 , the embodiment of the present invention provides an interactive device, including a touch display screen 1 and an infrared smart pen 2;

[0057] The touch display screen 1 includes an infrared touch frame 11, and the inner wall of the infrared touch frame 11 is provided with four infrared light bars 13, and the four infrared light bars 13 are respectively arranged in four directions of the inner wall;

[0058] The two infrared light bars 13 that are oppositely arranged are provided with a one-to-one corresponding first infrared emitter 131 and first infrared receiver 132, which are used to form touch recognition through the first infrared emitter 131 and the first infrared receiver 132 area for touch detection;

[0059]The infrared smart pen 2 comprises a smart pen microprocessor 22, a second infrared emitter 21 and a second i...

Embodiment 2

[0072] Figure 4 It is a method flow chart of a distance detection method provided in Embodiment 2 of the present invention. The distance detection method provided in the embodiment of the present invention can be used in the aforementioned interactive device. In this embodiment, based on the implementation process in the aforementioned interactive device, elaborate. refer to Figure 4 , the distance detection method, including:

[0073] Step S201: Touch the display screen to emit an infrared signal.

[0074] The infrared signal emitted by the touch display screen through the first infrared emitter realizes touch detection through the first infrared receiver, and at the same time, the energy radiated outward can also be received by the second infrared receiver in the infrared smart pen.

[0075] Step S202: The infrared smart pen confirms the source and receiving strength of the infrared signal according to the detected infrared signal.

[0076] The second infrared receiver...

Embodiment 3

[0081] Figure 5 It is a method flow chart of a distance detection method provided in Embodiment 3 of the present invention. The distance detection method provided in the embodiment of the present invention is used for the aforementioned interactive device. Refer to Figure 5 , the distance detection method, including:

[0082] Step S301: Touch the display screen to emit an infrared signal.

[0083] In order to ensure that the infrared signal emitted by the first infrared emitter is accurately identified and the intensity change of the infrared signal can be accurately judged, the infrared signal emitted by the touch screen carries the emission power of the infrared signal and the corresponding first infrared emission device feature code. Of course, the transmission power can be pre-stored in the infrared smart pen, and the infrared smart pen can directly read the data stored in itself.

[0084] Step S302: The infrared smart pen confirms the infrared transmitter correspondi...
