Autostereoscopic display device having touch sensing mechanism and driving method thereof

摘要

An autostereoscopic display device having touch sensing mechanism includes 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, and a control unit. The 2D/3D switching panel has a substrate, a first electrode disposed on the substrate, a counter substrate, and a second electrode disposed on the counter substrate. The control unit is employed to provide a first control signal and a second control signal furnished to the first electrode and the second electrode respectively. The first control signal is switched between a first high voltage and a first low voltage in a gradual-shift manner. The second control signal is switched between a second high voltage and a second low voltage in a gradual-shift or rapid-shift manner.

1. 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.
