Patent ID: 8482485

Claim:
An electronic display device to display a stereoscopic image, comprising: a display unit comprising a plurality of scan lines to transmit a plurality of selection signals to a plurality of pixels, a plurality of data lines to transmit a plurality of data signals to the plurality of pixels, the plurality of data signals formed according to input signals; and a barrier unit comprising: a plurality of first column barrier electrodes interposed with a plurality of second column barrier electrodes, the pluralities of the first and second column barrier electrodes respectively corresponding to the plurality of data lines, a plurality of row barrier electrodes, each of the plurality of row barrier electrodes corresponding to at least one of the plurality of scan lines, and a barrier driver that applies a barrier scan signal of a first level to one of the plurality of row barrier electrodes in synchronization with a selection signal applied to one of at least two scan lines of the plurality of scan lines, wherein: first crossing regions in which the plurality of the first column barrier electrodes and the plurality of row barrier electrodes cross and second crossing regions in which the plurality of the second column barrier electrodes and the plurality of row barrier electrodes cross transmit light emitted from the display unit differently along each of the plurality of row barrier electrodes, and the barrier driver applies the barrier scan signal of the first level to the one of the plurality of row barrier electrodes: in synchronization with a time when the selection signal is first applied to the at least two scan lines, in synchronization with a time when the selection signal is finally applied to the at least two scan lines, or at a predetermined time between the time at which the selection signal is first applied to the at least two scan lines and the time at which the selection signal is finally applied to the at least two scan lines.
