Title:
STYLUS PEN, TABLET AND STATE PARAMETER TRANSMISSION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/169628
Kind Code:
A1
Abstract:
Disclosed is a stylus pen, which comprises a controller, a driving chip, a sensing coil, a state parameter acquisition unit and a pressure sensor, wherein the controller is electrically connected to the driving chip, the state parameter acquisition unit and the pressure sensor, respectively; the driving chip is electrically connected to the sensing coil; the state parameter acquisition unit acquires a state parameter of a stylus pen; the pressure sensor acquires at least one writing pressure value of the stylus pen; the controller integrates the state parameter and the at least one writing pressure value to obtain at least one target pressure value; the controller transmits the target pressure value to the driving chip; and the driving chip drives the sensing coil to sequentially generate target pressure signals according to the at least one target pressure value and transmits the target pressure signals to a tablet. Further disclosed are a tablet and a state parameter transmission method. A state parameter of a stylus pen is acquired by a state parameter acquisition unit and is integrated with a writing pressure value into a target pressure value for transmission via a pressure channel, such that the transmission of the state parameter is realized.
