Abstract: A liquid crystal panel comprises a first substrate (11) and a second substrate (21) facing each other. A polarizer (30) is adhered to one side of the first substrate (11) orientated away from the second substrate (21). The liquid crystal panel further comprises a touch type input structure which is adhered on the outer surface of the polarizer (30) orientated away from the first substrate (11) to identify a touch signal; and an electromagnetic type antenna array at least comprising a first-direction conductive wire (51) and a second-direction conductive wire (52). The first-direction conductive wire (51) and the second-direction conductive wire (52) are respectively made of conductive material, and are formed on any one film between the first substrate (11) and the second substrate (21). The antenna array is used to identify an electromagnetic signal.

Abstract: An electromagnetic pen, an electromagnetic signal transmission method and an electromagnetic signal processing method, a processing device and a processing apparatus comprises: a reference inductance and a reference capacitor, connected with each other in parallel in a housing of the electromagnetic pen and configured to transmit an electromagnetic signal in a handwritten frequency; a control capacitor, connected with the reference capacitor in parallel and controlled by a control switch connected in series so as to transmit an electromagnetic signal in a control frequency. The processing device comprises: a receiving identification module, configured to receive the electromagnetic signal transmitted by the electromagnetic pen and identify a frequency of the electromagnetic signal; a handwritten input module, configured to input a handwritten symbol when the identified frequency is within a range of the handwritten frequency; and a control input module, configured to input a control signal.
