Embodiment Construction

[0037] Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. Throughout the specification, like reference numerals will indicate substantially similar components.

[0038]Before describing the embodiments of the present invention, terms used herein will be defined.

[0039] The multi-view autostereoscopic image display of the present invention can be implemented using various types of displays, including such as liquid crystal displays (LCDs), field emission displays (FEDs), plasma display panels (PDPs), organic light emitting diodes (OLEDs), and electrophoretic Flat panel displays such as EPDs. A multi-view autostereoscopic display can display 2D image data in a 2D mode and 3D image data in a 3D mode. The 3D optical elements in the multi-view autostereoscopic image display can be bonded to the display panel of the multi-view autostereoscopic image display.

[0040] The 3D optical element may be an optical...

Abstract

A multi-view autostereoscopic image display and a method of controlling an optimal viewing distance thereof are provided. The multi-view autostereoscopic image display includes a display panel displaying multi-view image data, a display panel driver writing the multi-view image data, a 3D optical element separating the optical axes of the multi-view image data, a viewing distance sensing unit sensing the positions of both eyes of a viewer, and a viewing distance extension controller that detects viewing zones where both eyes of the viewer are located by comparing the positions of both eyes of the viewer with positional information of predefined viewing zones, and selectively converts at least some of the multi-view image data according to a change in the positions of the viewing zones where both eyes of the viewer are located.

Description

[0001] This application claims the benefit of priority from Korean Patent Application No. 10-2012-0108794 filed on Sep. 28, 2012, which is incorporated by reference in its entirety for all purposes as if fully set forth herein. technical field [0002] The invention relates to a multi-view autostereoscopic image display and a method for controlling its optimal viewing distance. Background technique [0003] As stereoscopic image reproduction technology is applied to display devices such as televisions or monitors, it is now an era when people can watch 3D stereoscopic images even at home. Stereoscopic image displays can be classified into a glasses type and an autostereoscopic type. Glasses-type displays can display left and right parallax images on direct-viewing displays or projectors by changing their polarization direction or by time-division, and use polarized glasses or liquid crystal shutter glasses to realize stereoscopic images. In the autostereoscopic version, the...
