A method for testing crosstalk of a screen. The method includes when a main screen and a secondary screen simultaneously display pictures of different grayscales, determining a standard parameter value of crosstalk for each of the secondary screen and the main screen caused by the other; determining an actual parameter value of crosstalk for each of the secondary screen and the main screen caused by the other; calculating a degree of crosstalk for each of the secondary screen and the main screen caused by the other, according to the standard parameter value of crosstalk and actual parameter value of crosstalk for each of the secondary screen and the main screen caused by the other, respectively.

A three-dimensional display device includes a display panel including an active area to display, in the active area, a composite image including a first image and a second image having parallax with respect to the first image, a parallax barrier that defines a traveling direction of image light emitted from the active area, a position obtainer that obtains a position of a first eye of a viewer and a position of a second eye of the viewer different from the first eye, and a controller that causes the active area to display the composite image based on the positions of the first and second eyes. The active area includes multiple subpixels. The controller divides a screen of the display panel into multiple areas each having a specific reference index, and changes a parallax image with respect to the reference index.

Provided is an electronic device including a display to output an image, a parallax optical element configured to provide light corresponding to the image to a plurality of viewpoints, an input interface configured to receive an input to calibrate the parallax optical element by a user who observes a pattern image from a reference viewpoint among the plurality of viewpoints, and a processor configured to output the pattern image generated by rendering a calibration pattern toward the reference viewpoint, adjust at least one of a pitch parameter, a slanted angle parameter, and a position offset parameter of the parallax optical element based on the input, and output, by the display, the pattern image adjusted by re-rendering the calibration pattern based on an adjusted parameter.

A method and apparatus for measuring a dynamic crosstalk are provided. The method may include: controlling a driver configured to cause a camera to have a dynamic movement; at either one or both of a left eye position and a right eye position of a user, capturing a stereo pattern image output through a three-dimensional (3D) display, by the camera while the camera is in the dynamic movement; and measuring the dynamic crosstalk occurring by the 3D display based on the stereo pattern image captured by the camera.

A three-dimensional display apparatus includes a display surface, an optical element, and a controller. The display surface includes a plurality of subpixels arranged in a grid pattern along a first direction corresponding to a direction in which user's eyes are aligned and a second direction orthogonal to the first direction. The optical element defines a beam direction of light emitted by the display surface for each of a plurality of strip-shaped regions that extends in a direction on the display surface at a predetermined angle other than 0 degrees with respect to the second direction. The controller is configured to cause the display surface to display an image. The controller is configured to acquire brightness information and, based on the brightness information, reduce the luminance of at least a subset of binocular subpixels that have a portion included in a first visible region on the display surface for emitting light to a first eye position of a user and the remaining portion included in a second visible region on the display surface for emitting light to a second eye position of the user.
