Embodiment Construction

[0015] Please see attached figure 1 As shown, a touch-type blackboard includes: a display screen 1, and a remote controller 2. The remote controller emits a pulse modulation signal through an infrared light-emitting diode D to control the display, and two symmetrical suspension rings 3 are arranged on the top of the display.

[0016] We can directly write on the touch blackboard with our hands. If there is something wrong and needs to be changed, just press the remote control to confirm the content that needs to be deleted, and then delete it. The principle of the remote control to control the LCD touch screen is that the remote control sends a code, and emits a pulse modulation signal through the infrared light-emitting diode D. The TV receiving end decodes the code after receiving it, and outputs a control command after decoding.

[0017] In summary, the present invention can be widely used in school classrooms, reduces the harm of chalk dust to teachers and classmates, and ...
