Abstract

The invention discloses a digital panel, and an input processing method and apparatus. The digital panel comprises a passive pen used for inputting a resonant frequency based on an LC parallel resonant circuit, a board antenna array used for sensing the resonant frequency, and a board processing unit used for determining an initial range of the resonant frequency, detecting the resonant frequencyfor multiple times, performing calculation to obtain a difference and determining the resonant frequency of the passive pen. The technical problem of relatively low pressure sensing precision of the digital panel is solved. According to the method, the calculated pressure sensing precision is higher; a result is more accurate in comparison with a scheme in the prior art; the cost is relatively low; and the process requirements on the pen are not high.

Description

technical field [0001] The present application relates to the field of computers, in particular, to a digital tablet, an input method and a device. Background technique [0002] A digital tablet is a computer input device, usually composed of a tablet and a pressure-sensitive pen. [0003] The inventors have found that some existing digital boards have low precision due to the ratio calculation of pressure; other digital boards have MCU and capacitance change measurement devices for pressure-sensitive pens, and their energy comes from the energy emitted by the board. Device requirements are higher, which in turn results in higher costs. [0004] Aiming at the problem of relatively low precision of the digital board in the related art, no effective solution has been proposed yet. Contents of the invention [0005] The main purpose of this application is to provide a digital tablet to solve the problem of relatively low precision of the digital tablet. By converting the h...
