摘要:
An image display apparatus is provided that can display one or both of 2D imagery and 3D imagery in respective but randomly selectable display areas of the apparatus. The apparatus a display panel, a driving circuit part, a polarization switch panel and a lens. The driving circuit part processes received frame image data representing two-dimensional (2D) imagery and three-dimensional (3D) imagery to thus provide the display panel with the processed frame image. The polarization switch panel is disposed above the display panel. The polarization switch panel is switched into a first polarization mode in correspondence with 2D imagery being displayed by the display panel and it is switched into a second polarization mode in correspondence with 3D imagery being displayed by the display panel. The lens is reacts differently to light rays having the effect of the first polarization mode imparted to them and to light rays having the effect of the second polarization mode imparted to them. More specifically, the lens strongly refracts light rays that are imparted with the second polarization mode (3D imagery light) and weakly or not at all refracts light rays that are imparted with the first polarization mode (2D imagery light). Thus, both the 2D image and the 3D image may be displayed on one screen.

A stereoscopic image display device includes a display panel, a temporal division plate and a lenticular lens. The display panel includes a gate line, a data line, and a unit pixel of a horizontal pixel structure in which a long side is parallel with the first direction and a short side is parallel with the second direction. The display panel displays a 2D image based on an image control signal. The temporal division plate includes a plurality of shutters disposed on the display panel extending in the second direction. The temporal division plate opens and closes m shutters corresponding to each unit pixel, in a sequence, ‘m’ being a natural number no less than 2). The lenticular lens is disposed on the temporal division plate to convert the 2D image passing the temporal division plate into a 3D image.

A liquid crystal lens panel includes a first substrate, a second substrate, a liquid crystal layer and a light-blocking member. The first substrate includes a plurality of individual electrodes. The individual electrode receives a voltage to have a light path length distribution of a Fresnel lens shape. The second substrate includes a common electrode opposition the individual electrodes. The liquid crystal layer is disposed between the first and second substrates. The light-blocking member is disposed on an area in correspondence with the individual electrode in which a voltage discontinuously varied is applied thereto. Thus, a liquid crystal lens panel of a Fresnel lens type is realized to decrease a liquid crystal cell gap, so that a process efficiency of the liquid crystal lens panel may be enhanced and a manufacturing cost of the liquid crystal lens panel may be reduced.

The present invention provides an electro-optic unit. A lens unit disposed at an upper portion of a display panel has a plurality of lens part. An electro-optic unit is disposed between a display panel and a lens unit, and includes an electro-optic material layer formed as a graded refractive index lens in an electric field. A display device shows a two-dimensional and a three-dimensional image according to a mode of the electro-optic unit. A driving part may form the graded refractive index lens to have the same pitch as the pitch of the lens part. The graded refractive index lens may be formed as a convex lens or a Fresnel lens. The electro-optic unit is displayed to form the Fresnel lens. A driving method enhancing mode conversion velocity of the electro-optic unit is displayed.

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.
