Abstract: A new 2D/3D switchable display apparatus matches a polarization direction of light output from a 2D image display panel with a rubbing direction of a lower alignment layer of a liquid crystal lens, and tilts a rubbing direction of an upper alignment layer of the liquid crystal lens and a direction of a polarization axis of a polarizer at a predetermined angle, thereby reducing a loss of light passing through the liquid crystal lens, making it possible to improve luminance of images, improve the quality of 3D images in the horizontal direction, prevent or reduce color separation and moire phenomena, and reduce the manufacturing cost.

Abstract: A digital-to-analog converter may include a converting unit and a distributing unit. The converting unit may generate a first analog signal set based on less-than-all bits of an image data set in a first period and may generate a second analog signal set based on all bits of the image data set in a second period. The all bits may include at least 2 bits. The distributing unit may include output terminals, may distribute the first analog signal set to the output terminals in a first sequence in the first period, and may distribute the second analog signal to the output terminals in a second sequence. The second sequence may be opposite to the first sequence.

Abstract: An image display device includes a display panel displaying an image, and a diffractive element formed to operate in a 2D mode or a 3D mode so that the image of the display panel is perceived as a 2D image or a 3D image after passing through the diffractive element. In the image display device, the diffractive element includes a first substrate and a second substrate facing each other, a first electrode layer formed on the first substrate that includes a plurality of zones, a second electrode layer formed on the second substrate, and a liquid crystal layer interposed between the first substrate and the second substrate. Further, when the diffractive element operates in the 3D mode, a common voltage is applied to the second electrode layer, and polarity of voltages applied to the first electrode layer with respect to the common voltage is inverted every zone.

Abstract: A three-dimensional display device comprises a flat display panel and an image-converting sheet disposed on or above the display panel. The display panel comprises a matrix of unit display cells arranged as rows and columns and where the cells are spaced apart to have respective row and column direction pitches. The image-converting sheet comprises a plurality of inclined lenticular lenses where the inclination is set according to the row and column direction pitches so as to reduce perception of Moiré patterns when stereo-scopic images are projected through the image-converting sheet to an observer viewing the display panel as an upright panel having respectively different left and right stereo-scopic image projections.
