Display apparatus and method of displaying three dimensional images using plural barrier states

A display apparatus capable of displaying 3D images and comprising:

• a display panel that is configured to be driven by dividing a single 3D image frame into N sub frames displayed over time, N being greater than one;
• a display panel driver configured to provide first image data to the display panel for a first subset of the N sub frames and different second image data to the display panel for a second subset of the N sub frames;
• a light source part configured for providing light to the display panel;
• a light directing element disposed between the display panel and the light source part, the light directing element including a barrier part and a lens part, the lens part being interposed between the barrier part and the display panel, the barrier part having a plurality of first electrodes and a plurality of second electrodes crossing the first electrodes;
• and
• a barrier driver configured for controlling the barrier part so that a first barrier of the barrier part has a light transmitting state during corresponding stable display of a first subset of the sub frames and so that a second barrier of the barrier part, which second barrier is disposed adjacent to the first barrier, has a light transmitting state during corresponding stable display of the second subset of the sub frames;
• wherein the barrier driver is further configured for causing both of the first and second barriers to have respective and localized light blocking states for a corresponding localized portion of the display panel where display is transitioning from displaying imagery of one to the other of the first and second subsets of the N sub frames.
