Abstract: A liquid crystal display device includes a light source member and a display panel disposed on the light source member. The display panel includes a first substrate and a second substrate facing each other, a liquid crystal layer, and a color conversion layer that is disposed between the liquid crystal layer and the first substrate. The color conversion layer includes a light emitter and a low refractive body having a refractive index of about 1.0 to about 1.3. The liquid crystal display device exhibits high color reproducibility and improves external light extraction efficiency.

Abstract: A photoluminescence device for an image generating device includes a color conversion pattern, a color filter, and a low index of refraction layer. The color conversion pattern has a first refractive index and is configured to convert light transmitted from the image generating device from one wavelength to another. The color filter is configured to selectively pass light of a given range of wavelengths transmitted through the color conversion pattern. The low index of refraction layer has a second refractive index and is disposed between the color conversion pattern and the color filter. The second refractive index is lower than the first refractive index.

Abstract: An image display apparatus includes a display panel displaying an image, and a switching panel operated in a two-dimensional or three-dimensional mode. A viewer perceives the image of the display panel as a two-dimensional or three-dimensional image depending on the mode of the switching panel. The switching panel may include first and second substrates facing each other, a first electrode layer provided on the first substrate, a second electrode layer provided on the second substrate, and a liquid crystal layer interposed between the first and second substrates. One of the first and second electrode layers may include first and second electrodes provided on a specific plane, and two opposite inner sides of the first and second electrodes may be configured in such a way that lines extending therefrom converge on at least one first position.

Abstract: A 3D image display apparatus includes a light modulator configured to modulate an image light, a difference map generator configured to obtain an absolute value of a difference between a variation value of a left 2D image and a variation value of a right 2D image, an image processor configured to generate 3D image display position information using the absolute value, a light modulator controller configured to partially activate the light modulator in response to the 3D image display position information, an image generator for generating an interlaced image using the left and right 2D images, and an image display device for displaying the interlaced image. The activated area of the light modulator corresponds to an area of the displayed interlaced image, so that the light modulator modulates light provided from the displayed interlaced image, and does not modulate light provided from a remainder of the image.

Abstract: A display apparatus includes a display panel that displays an image using a first light, a light guide part positioned at a front side of the display panel, a backlight unit, an image information collecting part, and a processing part. The light guide part emits a second light different from the first light and guide the second light, and the backlight unit is positioned at a rear side of the display panel to provide the first light to the display panel. The image information collecting part photographs the light emitted from the light guide part to output image information. The processing part processes the image information to generate a coordinate value of a position at which an object provided on the light guide plate is positioned.
