Description

Display Device and Control Method of Display Device This specification relates to a display device and a method for controlling a display device. Recently, display technology that uses binocular parallax to represent three-dimensional images (stereoscopic images) is being utilized in various fields. These 3D display technologies are broadly classified into so-called stereoscopic display technology, which requires the observer to wear special glasses such as shutter glasses to view 3D images, and so-called auto-stereoscopic display technology, which does not require the use of glasses. However, these conventional 3D display technologies have disadvantages such as being cumbersome to use, requiring a complex structure, and having high manufacturing costs.
