This document discloses a stereoscopic image display device. In the image display device, a display device displays a first image data and a second image data in a time-dividing manner. A switchable retarder panel is configured to control light emitted from the display device and is made of electrically controlled birefringence (ECB) liquid crystals. Polarization glasses polarize the light emitted from the switchable retarder panel. The polarization glasses comprise a left eyeglass comprising a polarizer having a tilt of 45° about a light absorbing axis, and a right eyeglass comprising a polarizer having a tilt of 135° about the light absorbing axis.

An image processing apparatus includes an information obtaining unit configured to obtain parallax adjustment information with regard to a parallax-adjusted three-dimensional display material and an image transform unit configured to perform an inverse transform processing on the parallax-adjusted three-dimensional display material to be restored to a material before the parallax adjustment on the basis of the parallax adjustment information obtained by the information obtaining unit and generate a two-dimensional display material.

A method and apparatus for controlling a head-up display (HUD) considering an eye tracking status are provided. The method includes identifying an eye tracking status based on a result of an eye tracking, and identifying a rendering mode for an HUD image to be one of a two-dimensional (2D) rendering mode and a three-dimensional (3D) rendering mode based on the eye tracking status.

A display system is provided. The display system includes a virtual reality display apparatus, an autostereoscopic display apparatus, and a host. In response to a processing unit of the host receiving a specific input signal, the processing unit generates a display-mode control signal, executes an image-conversion software development kit of an OpenVR driver to convert a virtual-reality (VR) stereoscopic image, that is generated by a VR application executed by the host, into an autostereoscopic image, and writes the autostereoscopic image to a second image buffer of the host. In response to the display-mode control signal, the autostereoscopic display apparatus is switched to an autostereoscopic display mode, and a multiplexing circuit of the host selects the autostereoscopic image stored in the second image buffer as an output image signal, and sends the output image signal to the autostereoscopic display apparatus for displaying.

A three dimensional (3D) video signal is processed in a video device. The device has generating means for generating an output signal for transferring the video data via a high-speed digital interface like HDMI to a 3D display, which selectively generate a 3D display signal for displaying the 3D video data on a 3D display operative in a 3D mode, a 2D display signal for displaying 2D video data on the 3D display operative in a 2D mode, or a pseudo 2D display signal by including 2D video data in the output signal for displaying the 2D video data on the 3D display operative in the 3D mode. Processing means detects a request to display 2D video data on the 3D display, while the 3D display is operative in the 3D mode, and, in response to the detection, the generating means are set to generate the pseudo 2D display signal for maintaining the 3D mode of the 3D display.

A 3-dimensional image display device includes a signal controller, a data driver, a display panel, and glasses. The signal controller includes a reference gamma data generator to correct image data. The data driver includes a gray voltage generator to generate a gray voltage based on the corrected image data. The display panel displays left-eye and right-eye images based on a data voltage from the data driver. The lenses of the glasses are controlled by a glasses synchronization signal from the signal controller, to compensate for charging rates of the left-eye and right-eye images.

A display apparatus switching between a two-dimensional (2D) display mode and a three-dimensional (3D) display mode is provided. The display apparatus includes: an imaging device configured to capture an image a pair of 3D glasses worn by a user to view an image displayed in the 3D display mode, wherein the 3D glasses are switchable between a plurality of different states; a transmitter/emitter module configured to remotely control the 3D glasses so as to switch the states of the 3D glasses; and a controller configured to determine whether the user is wearing the 3D glasses based on a state of the 3D glasses in the image captured by the imaging device, and to control the display apparatus to operate in the 3D display mode when it is determined that the user is wearing the 3D glasses.

An illumination unit of an embodiment of the present technology includes: an illumination optical system configured to generate illumination light; and a plurality of lenses configured to reduce a divergence angle of the illumination light. The illumination optical system includes: a light source (20) configured to apply light onto an end surface of one of a first substrate and a second substrate; and a light modulation layer (30) provided in a gap between the first substrate and the second substrate. The illumination optical system includes an electrode configured to generate an electric filed that generates, in the light modulation layer (30), a plurality of linear scattering regions (30B) in a three-dimensional mode, and to generate an electric field that generates, in the light modulation layer, a planar scattering region in a two-dimensional display mode. The lenses are arranged side by side in a direction in which the linear scattering regions extend, and are also arranged side by side in a direction intersecting with the direction in which the linear scattering regions extend.

A multi-view display is switchable between single view and multi-view modes, and uses lenticular arrangement over a display panel which includes birefringent electro-optic material adjacent to a non-switchable optically transparent layer. The non-switchable optically transparent layer has a refractive index substantially equal to the extra ordinary refractive index of the birefringent electro-optic material. In the single view mode, the birefringent electro-optic material defines a non-switched state, and the polarization of the light from the display panel and incident on the lenticular arrangement is linear and aligned with the optical axis of the birefringent electro-optic material at the surface where the display output light is received. In the multi-view mode, the birefringent electro-optic material defines a switched state in which the optical axis is aligned perpendicularly to the display output surface.
