Abstract
A stereoscopic image display and a method for driving the same are disclosed. The stereoscopic image display includes a display element to which data of a left eye image is written during a data scanning time of the left eye image and data of a right eye image is written during a scanning time of the right eye image, an active retarder cell positioned on a display surface of the display element, and shutter glasses including a left eye shutter and a right eye shutter that are electrically controlled and are alternately opened and closed. The active retarder cell converts a polarization characteristic of light from the display element during an active retarder scanning time.

A stereoscopic image display comprising:
- a display element to which data of a left eye image is written during a data scanning time of the left eye image and data of a right eye image is written during a data scanning time of the right eye image;
- an active retarder cell positioned on a display surface of the display element, the active retarder cell configured to convert a polarization characteristic of light from the display element during an active retarder scanning time;
- and
- shutter glasses including a left eye shutter and a right eye shutter that are electrically controlled and are alternately opened and closed,
- wherein after a predetermined time has passed from the end of the data scanning time of the left eye image, the active retarder cell starts to be scanned,
- wherein after a predetermined time has passed from the end of the data scanning time of the right eye image, the active retarder cell starts to be scanned.
A method for driving a stereoscopic image display comprising:
- writing data of a left eye image to a display element during a data scanning time of the left eye image and writing data of a right eye image to the display element during a data scanning time of the right eye image;
- scanning an active retarder cell positioned on a display surface of the display element during an active retarder scanning time to convert a polarization characteristic of light from the display element;
- and
- electrically controlling a left eye shutter and a right eye shutter of shutter glasses to alternately open and close the left eye shutter and the right eye shutter,
- wherein after a predetermined time has passed from the end of the data scanning time of the left eye image, the active retarder cell starts to be scanned,
- wherein after a predetermined time has passed from the end of the data scanning time of the right eye image, the active retarder cell starts to be scanned.
