Embodiment approach
[0077] (1) The power supply of the oscillating circuit can be controlled through the first control signal, and when the first control signal is not received, the power supply of the oscillating circuit is kept in an off state; when the first control signal is received When receiving the first control signal, turn on the power supply of the oscillating circuit, so that the electromagnetic wave signal emitting element composed of the oscillating circuit and the inductive touch antenna board can emit the first electromagnetic wave signal.
[0078] (2) It can be controlled through the connection between the oscillation circuit and the inductive touch antenna board by the first control signal, and when the first control signal is not received, the oscillation circuit and the electric touch antenna board are kept The connection of the control antenna board is disconnected; when the first control signal is received, the oscillating circuit and the inductive touch antenna board are con...

The invention discloses an information processing method and device, which are applied to electronic equipment. The electronic equipment includes an electromagnetic screen, the electromagnetic screen can communicate with an electromagnetic pen, and the electromagnetic screen includes electromagnetic wave emitting elements. The electromagnetic pen includes an electromagnetic wave reflecting element, and the method is applied to the electronic device, including the following steps: transmitting a first electromagnetic wave signal through the electromagnetic wave emitting element; receiving a second electromagnetic wave signal, wherein the second electromagnetic wave signal It is the electromagnetic wave signal reflected by the electromagnetic pen to the electromagnetic screen through the reflective element after receiving the first electromagnetic wave signal; based on the second electromagnetic wave signal, the operation of the electromagnetic pen on the electronic device is realized. By adopting the method and device of the present invention, it is possible to avoid the situation that the user cannot operate the electronic device because the electromagnetic pen is out of power when the user needs to use it, and the usability of the electronic device is improved.
Description
technical field [0001] The present invention relates to the field of electronic technology, in particular to an information processing method and device. Background technique [0002] Electromagnetic induction touch technology is a technology applied to portable IT products earlier, and its characteristic is that it needs a "pen" instead of fingers. The pen can emit electromagnetic waves, and the position of the pen above the screen can be sensed by the receiving device to locate it. When the accuracy problem of other touch screens has not been solved, early PDAs, electronic dictionaries and handwriting tablets all used this method. Inductive touchscreens function on mobile phones and tablets to this day. The electromagnetic induction touch screen is low in cost, simple in structure, convenient for handwriting input, and can also be integrated with other touch screens, so it is very popular. [0003] Electronic products with electromagnetic screens on the market (such as ...
