Abstract:
1. A 3D image display, comprising: a display panel including a plurality of color pixels, and configured to display an image, wherein each of the plurality of color pixels includes a color filter surrounded by a black matrix; and a liquid crystal lens unit positioned over the corresponding color pixels for displaying a 3D stereoscopic image of the image displayed on the display panel, the liquid crystal lens unit including a first substrate positioned over the display panel including the plurality of color pixels, a second substrate positioned over the first substrate on a side of the first substrate opposite the display panel including the plurality of color pixels, a liquid crystal layer positioned between the first and second substrates, and a plurality of field generating electrodes, wherein voltage is applied to the plurality of field generating electrodes for producing a focus profile of light emitted from the corresponding pixels, wherein voltage applied to the plurality of field generating electrodes is fluctuated at a frequency so that the focus profile is oscillated within the corresponding pixels, and the frequency of an oscillation of position of the focus profile between one side and another side of the corresponding pixels is 60 Hz or more, wherein when the position of the oscillated focus profile is on the black matrix of the corresponding pixels, the black matrix is seen by a viewer, and wherein when the position of the oscillated focus profile is on the color filter of the corresponding pixels, color of the color filter is seen by the viewer.
