The intelligent digital interactive flat electronic laser pen can actually perform the top-down startup function on the remote control computer. In an insulating shell, it is successively connected with a pen, an electronic induction handle coil, an electronic induction pen circuit and a feeder. On the other hand: a series of RF transmitters, laser transmitter array, laser transmitter circuit, RF transmitter, laser head and laser receiver. The digital interactive control function of whiteboard on computer is realized, and the other function is to realize laser pen on paper. During operation, the computer is remotely controlled and page up and down functions are performed. The handle can also be an intelligent physical pointer. Digital interactive planar electronic laser pen. The laser emission circuit is powered by a battery connected to an electrical switch, which has two positions for controlling the opening and closing of the whole laser pen. When the battery is disconnected and the power switch is in the off position, the laser emission circuit will not light up. When the power switch is turned on, the laser emission circuit is connected to the battery, and the laser pen emits lasers of different colors.
In order to overcome the disadvantages of electronic touch pen and digital laser baffle, the invention integrates two functions. The digital interactive electronic Laser pointer replaces the mouse and can work directly on the interactive whiteboard. When you walk through the presentation, the presentation page will show the remote transmission of the laser pen. It can also be used as a direct acting physical pointer. Modern technology using monochrome laser pen can not adapt to the background color of PPT. This greatly limits the use of the laser pen and makes it very uncomfortable. It is not reported that the electronic laser pen can adjust the color of the laser, and similar documents and technical documents have been collected at home and abroad. The current value of the DC circuit can be adjusted by changing the AC resistance value in the circuit, so as to obtain the laser radiation intensity on the corresponding color laser diode.
