STEREOSCOPIC TOUCH DISPLAY DEVICE

摘要

A stereoscopic touch display device includes a display panel and a stereoscopic touch panel. The stereoscopic touch panel includes a first substrate, a second substrate, a liquid crystal layer, receiver electrodes, transmitter electrodes, common electrodes, a signal driver, and a common potential providing unit. The liquid crystal layer is disposed between the first and second substrates. The receiver electrodes and the common electrodes are disposed on the first substrate. The transmitter electrodes are disposed on the second substrate. The signal driver is electrically connected to the transmitter electrodes and the receiver electrodes. The signal driver is configured for providing transmitting touch signals to the transmitter electrodes and detecting receiving touch signals generated from coupling capacitances between the receiver electrodes and the transmitter electrodes in sequence. Each of the transmitting touch signals is configured so as to be unable to trigger liquid crystal molecules of the liquid crystal layer.
