A signal generating circuit for providing signals to a gate driving circuit of a display device is provided. The gate driving circuit has plural shift registers each having a main circuit unit and a discharge circuit unit. The discharge circuit units of at least some of the shift registers are configured to receive a pull-down control signal. The main circuit unit of a first stage shift register of the shift registers is configured to receive a starting signal. The signal generating circuit includes a first circuit unit that is configured to output the pull-down control signal and the starting signal to the gate driving circuit. The starting signal switches from a disabling voltage level to an enabling voltage level at a first time point. The pull-down control signal switches from a disabling voltage level to an enabling voltage level at a second time point before the first time point.

Signal generating circuit and display device

An auto-stereoscopic three-dimensional (3D) display including a display module and a driving module is provided. The display module includes a display panel and a barrier unit. The display panel has odd-column pixels and even-column pixels. The barrier unit coordinates with a left-eye image and a right-eye image displayed by the display panel to switch vertically and alternatively arranged slits and barriers, so as to produce a stereoscopic image in a viewer's eyes through parallax. The driving module provides left-eye image data and right-eye image data to drive the display module. The driving module drives the odd-column and even-column pixels respectively according to different driving timings, so as to respectively and sequentially enables the odd-column and even-column pixels during a plurality of corresponding frame periods to receive the left-eye image data and the right-eye image data and allow the display panel to display the left-eye and right-eye images.

Auto-stereoscopic three-dimensional display and driving method thereof

A display method of a two-dimensional and naked eye type stereoscopic switchable display device is disclosed. The two-dimensional and naked eye type stereoscopic switchable display device includes a two-dimensional and naked eye type stereoscopic switchable display module, at least one detection device and an indicator device. The two-dimensional and naked eye type stereoscopic switchable display module provides a plurality of stereoscopic image regions in a naked eye type stereoscopic display mode. Then, detect a viewer's position with the detection device. And, determine whether or not the viewer's position is in the stereoscopic image regions with the two-dimensional and naked eye type stereoscopic switchable display device. When the viewer locates in the stereoscopic image regions, the indicator device emits a first color light. When the viewer locates outside of the stereoscopic image regions, the indicator device emits a second color light.
