Three-dimensional image display device and driving method thereof

A Three-Dimensional (3D) image display device, comprising:

• a panel comprising a plurality of left-eye pixels and right-eye pixels;
• a barrier panel disposed at a front surface of the panel, and comprising a light transmitting area and a light blocking area for transmitting or blocking a left-eye image and a right-eye image which are respectively outputted from the left-eye pixel and the right-eye pixel;
• an image collector collecting images of a user;
• an image data alignment unit realigning video data suitably for the panel to output image data, the video data being received from a system;
• a position determination unit extracting position coordinates of the user from the images of the user, the images of the user being collected by the image collector;
• and
• a control unit outputting a test image to the panel, generating and storing a view map by using a plurality of view selection signals received from the system and the position coordinates of the user extracted by the position determination unit when the view selection signals are received from the system, in a view map correction mode that is selected by the user,
• wherein in a 3D image viewing mode, the control unit determines which of a plurality of viewing zones for a 3D image current position coordinates of the user correspond to using the current position coordinates extracted by using the images collected by the image collector and the view map set and stored in the view map correction mode that is selected by the user, and
• when a determined result shows that the current position coordinates do not correspond to an orthoscopic zone that is a comfortable zone for viewing the 3D image, the controller adjusts the barrier panel so that the current position coordinates correspond to the orthoscopic zone without a change in a physical position of the user.

A driving method of a Three-Dimensional (3D) image display device, the driving method comprising:

• outputting a first test image, generated with a first view, onto a panel, receiving a first view selection signal from a system, and extracting first position coordinates of a user in the middle of receiving the first view selection signal, when a view map correction mode is selected by the user;
• outputting a second test image, generated with the first view, onto a panel, receiving a second view selection signal from the system, and extracting second position coordinates of the user in the middle of receiving the second view selection signal, when the first view selection signal is received;
• generating a view map with the first and second position coordinates to store the view map, the view map comprising coordinates of a plurality of orthoscopic zones which are formed with a 3D image comprising at least two or more views;
• determining whether a current position coordinates correspond to an orthoscopic zone by using the current position coordinates of the user and the view map set and stored in the view map correction mode that is selected by the user, when a 3D image viewing mode is selected;
• and
• in the 3D image viewing mode, when a determined result shows that the current position coordinates do not correspond to an orthoscopic zone that is a comfortable zone for viewing the 3D image, controlling a barrier panel so that the current position coordinates correspond to the orthoscopic zone without a change in a physical position of the user,
• wherein the current position coordinates is extracted from images which are collected by an image collector.
