At this time, the operation of infrared touch and display can also be completed by only using the main display 11 alone, wherein the second infrared touch frame 212 can form the infrared touch sensing area 70 on the main display 11 area, so that the main display 11 can also use the infrared touch function after being separated from the interactive panel 12.

When the main display screen 11 is used alone, the main display screen 11 may be used alone, or the electronic blackboard 100 may be assembled for use, and when the main display screen 11 is used alone, an infrared touch sensing area covering the whole main display screen 11 is formed between the infrared touch units 22 in the second infrared touch frame 212 of the main display screen 11, so as to perform touch operation on the main display screen 11 alone, at this time, the infrared touch units 22 receive the changed infrared signal and transmit the signal to the control unit 60, and the control unit 60 controls the main display screen 11 to perform display processing and the like; when the assembled electronic blackboard 100 is used, the first infrared touch frames 211 and the second infrared touch frames 212 at the two ends are electrically connected, that is, the infrared touch units 22 in the first infrared touch frames 211 and the second infrared touch frames 212 jointly form an infrared touch sensing area covering the writing display area 30, that is, the infrared touch functions can be used on the main display screen 11 and the interactive panel 12, so that the infrared touch and writing functions are realized.

The present embodiment provides an electronic blackboard 100, in which a first infrared touch frame 211 and a second infrared touch frame 212 are respectively disposed around the outer sides of the main display 11 and the interactive panel 12, and the second infrared touch frame 212 can be connected to each other through compatibility, thereby, the main display 11 can be used independently, and the electronic blackboard 100 can be assembled into a whole for use, the operation and the adjustment are more convenient, in addition, both the main display 11 and the interactive panel 12 of the display module 10 can simultaneously implement touch operations and handwriting recordings through the infrared touch sensing area, so as to implement infrared touch and writing functions, meanwhile, the main display screen 11 and the interactive panel 12 are located on the same plane, and the edges of the main display screen 11 and the interactive panel 12 are adjacent to each other, so that the overall size is reduced, the occupied space is reduced, and the installation is more convenient.
