Abstract

The invention provides an electromagnetic handwriting device and a method for arranging antennae of the electromagnetic handwriting device. The electromagnetic handwriting device comprises an electromagnetic handwriting plate and an electromagnetic input pen which is used for performing handwriting input on the electromagnetic handwriting plate, wherein the electromagnetic handwriting plate comprises an antenna plate and a control plate which controls the antenna plate; the antenna plate comprises transmitting coils and receiving coils; the transmitting coils transmit electromagnetic waves tothe electromagnetic input pen; the receiving coils are staggered with the transmitting coils and used for receiving the electromagnetic waves which are reflected after the electromagnetic input pen receives the electromagnetic waves transmitted by the transmitting coils; and at least the transmitting coils or the receiving coils are in a reuse structure. The method for arranging the antennae of the electromagnetic handwriting device comprises the step of: setting at least the transmitting coils or the receiving coils in the reuse structure. By the electromagnetic handwriting device and the method, the arrangement number of the antennae is small and the antennae are easy to arrange; in addition, the method can be widely applied in the electromagnetic handwriting device.

Description

technical field [0001] The invention relates to a wiring method for a handwriting device and its antenna, in particular to an electromagnetic handwriting device and a wiring method for its antenna. Background technique [0002] Electromagnetic handwriting technology has the characteristics of high precision, pressure sensitivity when handwriting, and does not affect the display effect of the display screen. Therefore, it is widely used in various electronic products such as handwriting computers, e-books, and handwriting LCD screens. [0003] Generally, an electromagnetic handwriting device consists of an antenna area and a control area. Currently, the number of transmitting antennas in the antenna area is closely related to the size of the electromagnetic handwriting device, that is, the larger the size of the electromagnetic handwriting device, the greater the number of transmitting antennas. In this way, when the number of transmitting antennas reaches a certain level, t...
