Abstract

The invention provides 2D / 3D switchable image display device. The device includes an image panel, a backlight unit arranged at the rear side of the image panel, and a lenticular lens sheet arranged between the image panel and the backlight unit. The backlight unit includes a plurality of segment light sources for a left eye vision range which emit a light for a left eye vision range, and a plurality of segment light sources for a right eye vision range which emit a light for a right eye vision range. The segment light sources for the left eye vision range and the segment light sources for the right eye vision range are alternately arranged to form a surface light source. The lenticular lens sheet includes a plurality of semi-cylindrical lenses arranged in a direction perpendicular to a viewing direction of both eyes of a viewer.

Description

Technical field [0001] The device according to the present invention relates to a backlight unit and a two-dimensional / three-dimensional switchable liquid crystal display (LCD) using the backlight unit, and more specifically, to such a backlight unit having a simple structure, The light of the vision range of the left eye and the vision range of the right eye is supplied to the lenticular lens sheet, and relates to a two-dimensional / three-dimensional switchable LCD using such a backlight unit. Background technique [0002] With the development of technology, a display capable of displaying more realistic images is required. Therefore, high-resolution displays with an increased number of pixels for displaying images have been developed, and three-dimensional image displays capable of displaying three-dimensional images are also being developed. Thus, the three-dimensional image display can be applied not only to televisions (TV), but also to various uses, including medical imaging...
