Abstract

The invention provides a digital panel device which comprises a panel body and a passive pen, wherein the passive pen is communicated with the panel body. The panel body comprises a signal amplification and control processing circuit, an interface module, an analog switch circuit, a receiving antenna array, a high-frequency signal source and a first transmitting antenna, wherein the interface module and the analog switch circuit are electrically connected with the signal amplification and control processing circuit, the receiving antenna array is electrically connected with the analog switch circuit, and the first transmitting antenna is electrically connected with the high-frequency signal source and arranged around the receiving antenna array. According to the digital panel device, the first transmitting antenna and the receiving antenna array are independently arranged in a separated mode, the first transmitting antenna is specially used for powering the passive pen, the receiving antenna array is specially used for receiving the signals of the passive pen, the first transmitting antenna and the receiving antenna array are independent in terms of functions, antenna function switching is not needed, switching time is reduced, therefore reaction speed of the digital panel device can be accelerated, a switching circuit of antenna functions is canceled, the circuit structure is simplified, and production cost is reduced to a certain extent.

Description

technical field [0001] The invention relates to the field of computer input equipment, in particular to a digital board device. Background technique [0002] Digital board, also known as drawing board, drawing board, hand-painted board, etc., is a kind of computer input device, usually composed of a board body and a pressure-sensitive pen, it is related to handwriting board as unconventional input products Similarly, they are all aimed at a certain user group. The difference from the handwriting board is that the digital board is mainly aimed at design office workers. It is used for painting creation, just like a painter's drawing board and brush. The lifelike pictures and lifelike characters we often see in movies are said to be digital. It was drawn stroke by stroke on the board. The drawing function of the digital tablet is incomparable with keyboards and handwriting tablets. [0003] The hardware of the digital board adopts the principle of electromagnetic induction. ...
