Abstract
A Depth-Fused 3D (DFD) display, a driving method thereof and a driving circuit thereof are provided. The driving method includes the steps listed below. During a first frame time, a foreground image signal is provided to a front panel and a first uniform image signal is provided to a rear panel. During a second frame time, a background image signal is provided to the rear panel and a second uniform image signal is provided to the front panel.
Claims21
A driving method, for driving a front panel and a rear panel of a depth-fused 3D (DFD) display, comprising:
- providing a foreground image signal to the front panel and providing a first uniform image signal to the rear panel during a first frame time;
- and
- providing a background image signal to the rear panel and providing a second uniform image signal to the front panel during a second frame time.
A driving circuit, comprising:
- a first driving unit, coupled to a front panel;
- and
- a second driving unit, coupled to a rear panel,
- wherein during a first frame time, the first driving unit provides a foreground image signal to the front panel, and the second driving unit provides a first uniform image signal to the rear panel, and
- during a second frame time, the second driving unit provides a background image signal to the rear panel, and the first driving unit provides a second uniform image signal to the front panel.
A depth-fused 3D (DFD) display, comprising:
- a front panel and a rear panel, respectively having a first polarizer and a second polarizer, wherein the first polarizer is disposed on a surface of the front panel which is opposite to the rear panel, and the second polarizer is disposed on a surface of the rear panel which is opposite to the front panel;
- a backlight module, wherein the rear panel is disposed between the backlight module and the front panel;
- and
- a driving circuit, coupled to the front panel and the rear panel, wherein during the first frame time, the driving circuit provides a foreground image signal to the front panel and provides a first uniform image signal to the rear panel, and during a second frame time, the driving circuit provides a background image signal to the rear panel and provides a second uniform image signal to the front panel.
