A pixel driving circuit includes a first capacitor, a data input unit, a liquid crystal capacitor, a control unit and a driving unit. The first capacitor has a first terminal and a second terminal, wherein the first terminal is configured for receiving a first reference voltage. The data input unit is configured for inputting a data signal to the second terminal of the first capacitor according to a first scanning signal. The liquid crystal capacitor has a first terminal and a second terminal. The first terminal receives a first operating signal. The control unit is configured to control a voltage of the second terminal of the liquid crystal capacitor according to a second scanning signal. The driving unit is configured to control the voltage of the second terminal of the liquid crystal capacitor in response to the data input unit is disabled by the first scanning signal.

Pixel driving circuit and driving method thereof

A sensing device is provided. The sensing device includes a semiconductor layer, a first electrode and a second electrode, a first detection electrode and a second detection electrode, and at least one conductive pattern. The first electrode and the second electrode are disposed at opposite ends of the semiconductor layer. The first detection electrode and the second detection electrode are disposed at the other opposite ends of the semiconductor layer, wherein a virtual connection line is provided through the first detection electrode and the second detection electrode. The at least one conductive pattern is disposed on the semiconductor layer, wherein the conductive pattern does not overlap with the virtual connection line.

Sensing device

A touch-screen system including a stylus, a display panel and a touch module is disclosed herein. The stylus includes a magnetic component. The touch-sensing module is disposed within the display panel. The touch-sensing module includes a plurality of sensing units distributed at different locations as an array over the display panel. Each of the sensing units includes a Hall induction plate for sensing a magnetic field established by the magnetic component and forming an induction output voltage. The touch module detects a touch position of the stylus according to the induction output voltages from the sensing units.
