Patent ID: 8791919

Claim:
An autostereoscopic display device having touch sensing mechanism, comprising: a display panel for illustrating images; a touch sensing panel for detecting touch events; a 2D/3D switching panel, disposed between the display panel and the touch sensing panel, the 2D/3D switching panel having a first substrate, a first electrode disposed on a first panel surface of the first substrate, a second substrate opposing to the first substrate, and a second electrode disposed on a first panel surface of the second substrate; and a control unit, electrically connected to the first and second electrodes, for providing a first control signal and a second control signal furnished to the first and second electrodes respectively, wherein the first control signal is switched between a first high voltage and a first low voltage in a gradual-shift manner; wherein the first control signal received at the first electrode is pulled from the first low voltage upward to a first intermediate voltage between the first high voltage and the first low voltage during a first interval; the first control signal received at the first electrode is pulled from the first intermediate voltage upward to a second intermediate voltage between the first high voltage and the first intermediate voltage during a second interval following the first interval; the first control signal received at the first electrode is pulled from the second intermediate voltage upward to a third intermediate voltage between the first high voltage and the second intermediate voltage during a third interval following the second interval; and the first control signal received at the first electrode is pulled from the third intermediate voltage upward to the first high voltage during a fourth interval following the third interval.
