Abstract
A touch controlled device with a pressure sensing electronic input pen comprises a main control unit, a pressure signal processing unit, an electronic input pen, a coordinate and button signal processing unit, a touch control panel, and an output interface, etc. The main control unit serves to process the outputting signals from the pressure signal processing unit and the coordinate and button signal processing unit. The electronic input pen has a pressure sensor and a button, the pressure sensor serves to sense the force applied for being outputted with a pressure frequency signal. The touch control panel is connected to the coordinate and button signal processing unit, the tip of the electronic input pen touches the touch control panel so that the touch control panel outputs a coordinate signal and then transfers this signal to the coordinate and button signal processing unit. The coordinate and button signal processing unit processes the control signal from the button of the electronic input pen and the coordinate signal outputted from the touch control panel, the processed signals are transferred to the main control unit and which is transferred to a computer through an output …
