Previously, users could not be notified when the 3D mode type of a program being received by a digital broadcast receiver was not compatible with the digital broadcast receiver. A reception device is provided with: a reception unit which receives program content including video information and identification information including information for distinguishing whether the program content is 2D program content or 3D program content; and a display control unit which controls the display so as to display whether the aforementioned program content is 2D program content or 3D program content in response to the received aforementioned identification information.

An electronic device includes a memory, a display and a processor configured to set at least one virtual plane in a three-dimensional (3D) virtual position based on at least a portion of at least one two-dimensional (2D) first image displayed on the display, set a 3D virtual space comprising the at least one virtual plane and the at least one 2D first image, insert a 3D object into the 3D virtual space, and generate at least one 2D second image by synthesizing the 3D object inserted into the 3D virtual space and the at least one 2D first image.

A video display system includes a source device for reproducing and outputting contents; and a display device for displaying contents which is output from the source device. Upon receiving a message for requesting display of a 3D video from the source device in a state of unreadiness to display the 3D video, the display device transmits a message for stopping reproduction of 3D contents to the source device. Upon receiving the message for stopping reproduction of 3D contents, the source device stops reproduction of the 3D contents. Upon completing preparations for displaying the 3D video, the display device transmits a message for reproducing the 3D contents to the source device. Upon receiving the message for reproducing the 3D contents, the source device reproduces and outputs the 3D contents.

Embodiments of the present invention provide a 3D display device, and the 3D display device, comprising: a display panel (1), configured to display an image; an optical element (2) and a liquid crystal lens (3), disposed to overlap each other and positioned at a light exiting side of the display panel (1), wherein the optical element (2) comprises a plurality of optical lens units (2a), the liquid crystal lens (3) comprises a plurality of liquid crystal lens units (3a), the plurality of liquid crystal lens units (3a) correspond to the plurality of optical lens units (2a) in a one-to-one corresponding relationship; when the 3D display device is in a 2D displaying mode, each of the plurality of liquid crystal lens units (3a) has an effect on light contrary to an effect on the light of each of the plurality of optical lens units (2a), and when the 3D display device is in a 3D displaying mode, the liquid crystal lens unit (3a) is configured to have a plane glass function. The 3D display device provided by the embodiments of the present invention can be switched between 2D and 3D displaying, and can reduce the crosstalk during 3D displaying and improve the display effect.

An organic light-emitting diode (OLED) display and method of driving the same are disclosed. In one aspect, the OLED display includes a display panel including a plurality of pixels and a data driver configured to apply a data signal to the display panel in one of two-dimensional (2D) and stereoscopic display modes. The display also includes a controller configured to convert an image signal to 2D image data for the pixels at each of N×k sub-fields in the 2D display mode and convert the image signal to stereoscopic image data for the pixels at each of N sub-fields in the stereoscopic display mode, where N and k are integers greater than 1. The display further includes a frame memory configured to store the 2D image data in the 2D display mode and the stereoscopic image data in the stereoscopic display mode.

A system for display three dimensional content on a display.
