Abstract: A stereoscopic display apparatus and a display method are provided. The stereoscopic display apparatus includes a display panel, a dynamic-backlight module, a tracking panel, an optical lens array. The display has an updated region and a non-updated region during a frame period the display panel displays according a first synchro-signal. The dynamic-backlight module has a plurality of light-emitting regions and the light-emitting regions are turned-on according to a second synchro-signal. The first synchro-signal and the second synchro-signal are synchronal. During the frame period, parts of the light-emitting regions corresponding to the updated region are synchronally turned-on and parts of the light-emitting regions corresponding to the non-updated region are synchronally turned-off. A light provided by at least the part of the light-emitting regions turned-on passes through one silt set and the display panel such that one of the single-eye images is only displayed by the non-updated region.
Abstract: Scan driver and driving system with low input voltage and their level shift circuit are disclosed. The scan driver includes a latch unit, a level shift circuit and a buffer. The latch unit generates a first control signal and a second control signal. The level shift circuit is connected to the latch unit to receive the first control signal, the second control signal, a first clock signal and a second clock signal, so as to output a scan signal with high voltage level. The buffer enhances driving ability of the scan signal for driving thin-film transistors (TFTs) of a display panel.
