Abstract
Embodiments relate to a display device and a method of driving the same. The display device in one or more examples includes an eye-tracking unit configured to capture a viewer image, a control unit configured to convert an externally input image signal into image data, identify a viewer's position relative to a display module based on the viewer image, and align and output the image data based on a view map corresponding to the viewer's position, a data driver configured to convert the image data output from the control unit into a data voltage and output the data voltage, and the display module configured to display a three-dimensional image based on the data voltage.
Claims20
A three-dimensional image display device comprising:
- an eye-tracking unit configured to capture a viewer image;
- a control unit configured to convert an externally input image signal into image data, identify a viewer's position relative to a display module based on the viewer image, and align and output the image data based on a view map corresponding to the viewer's position;
- a data driver configured to convert the image data output from the control unit into a data voltage and output the data voltage;
- and
- the display module configured to display a three-dimensional image based on the data voltage,
- wherein the display module comprises:
- a display panel having a display area in which pixels are arranged and a non-display area adjacent to the display area;
- and
- a lens array disposed on the display panel, and
- wherein the display module is configured to display a reference pattern in the non-display area to determine a misalignment between the eye-tracking unit and the display module.
A method of driving a three-dimensional image display device including a camera configured to capture an image, and a display module including a display panel having a display area in which pixels are arranged and a non-display area adjacent to the display area, and a lens array disposed on the display panel, the display module being configured to display a reference pattern, the method comprising:
- capturing a reflected image disposed in front of the display module through the camera while the display module displays the reference pattern;
- determining a misalignment between the camera and the display module based on a reflected image of the reference pattern included in the reflected image;
- calculating a compensation value to correct the misalignment;
- capturing a viewer image through the camera;
- correcting the viewer image based on the compensation value;
- identifying a viewer's position relative to the display module based on the corrected viewer image;
- and
- aligning and displaying image data of a three-dimensional image according to a predefined view map corresponding to the viewer's position.
