The invention provides a writing operation method for an electromagnetic screen and the electromagnetic screen. The method comprises the steps of obtaining device information of a plurality of input devices; marking the input devices as different operation devices according to a preset configuration file, wherein the preset configuration file is an IDC input device configuration file; starting handwriting software; monitoring current events of the different operation devices; judging whether the current events are preset events corresponding to the operation devices or not; and if yes, obtaining handwritings corresponding to the operation devices according to coordinate positions of the current events. Through the design of the preset configuration file, the input devices can be effectively set as the different operation devices, so that the handwriting software makes responses to the different operation devices when performing event response, and the phenomenon of handwriting errors during simultaneous operation of the input devices is prevented.
Description
technical field [0001] The invention relates to the technical field of electromagnetic screens, in particular to an electromagnetic screen writing operation method and the electromagnetic screen. Background technique [0002] With the development of the times, the advancement of science and technology, and the continuous improvement of people's living standards, electromagnetic screens are used more and more frequently. Electromagnetic screens are devices that operate according to electromagnetic signals. Electromagnetic screens have the advantages of high sensitivity and low energy consumption. It is widely used in electronic equipment such as tablets, computers, and conference machines. [0003] The existing writing operation method of the electromagnetic screen is to first obtain the pressing signal of the electromagnetic pen, and then query the coordinates corresponding to the pressing signal, so that the trajectory display is performed according to the queried coordinat...
