Electronic display device and method thereof

An electronic image device comprising:

• a display unit comprising a plurality of scan lines for transmitting a plurality of selection signals, a plurality of data lines for transmitting a plurality of data signals, and a plurality of pixels coupled to the scan lines and the data lines;
• a data driver for converting input data into the plurality of data signals and transmitting the plurality of data signals to the plurality of data lines in synchronization with the selection signals;
• a controller for reading an input signal, wherein when the input signal comprises stereoscopic image data having at least one stereoscopic image, each stereoscopic image frame is displayed in at least two periods comprising a first period and a second period, transmitting a first period stereoscopic image data corresponding to the stereoscopic image frame to the data driver so that a first period stereoscopic image is displayed during the first period, and transmitting a second period stereoscopic image data corresponding to the stereoscopic image frame to the data driver so that a second period stereoscopic image is displayed during the second period, and wherein when the input signal comprises plane image data, transmitting the plane image data to the data driver to display a plane image during the first period, and transmitting the plane image data to the data driver to display the same plane image during the second period;
• and
• a barrier layer comprising a first barrier driven during the first period and a second barrier driven during the second period,
• wherein the barrier layer has a same first barrier pattern during the first period for both the plane image and the first period stereoscopic image, and
• wherein the barrier layer has a same second barrier pattern during the second period for both the plane image and the second period stereoscopic image.

A driving method of an electronic image device comprising a display unit for displaying an image and a barrier layer on the display unit, the method comprising:

• dividing data included in an input signal into plane image data and stereoscopic image data;
• dividing a frame period for displaying the image of one frame into at least two periods comprising a first period and a second period;
• displaying a first stereoscopic image generated by using the stereoscopic image data on the display unit during the first period, and displaying a second stereoscopic image that is different from the first stereoscopic image generated from the stereoscopic image data on the display unit during the second period;
• displaying through the barrier layer a plane image generated by using the plane image data during the first and second periods;
• and
• in the barrier layer, generating a non-transmission area and a transmission area in an alternating pattern in the first period, and alternating the non-transmission area and the transmission area in the second period.
