Title:
THREE-DIMENSIONAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/121982
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a three-dimensional display device that is capable of preventing the malfunctioning of a touch panel, while maintaining 3D characteristics. This three-dimensional display device is provided with: a display panel (12), a switch liquid crystal panel (14), a touch panel (20), a drive circuit (16), and a resistor-capacitor (RC) circuit. The switch liquid crystal panel (14) is positioned on the surface side of the display panel (12), enabling a parallax barrier (38) to be achieved. The touch panel (20) is positioned on the surface side of the switch liquid crystal panel (14). The drive circuit (16) drives the switch liquid crystal panel (14), providing a parallax barrier (38). The RC circuit (18) is positioned between the switch liquid crystal display panel (14) and the drive circuit (16). The drive circuit (16) has an effective voltage value of 3 V or higher when driving the switch liquid crystal panel (14).
