Liquid crystal lens and stereoscopic display device

Abstract

The invention provides a liquid crystal lens. The improvement is that a second electrode in a first lens unit comprises a plurality of bar electrodes which are same in width and equal in separation distance and extend along the y direction; a first insulation layer is arranged on the second electrode and provided with an opening in a position corresponding to the second electrode; a third electrode is arranged on the first insulation layer; the third electrode comprises two parts, the first part is a bar electrode in a position corresponding to the opening of the first insulation layer, and the second part is a suspended bar electrode arranged between every two bar electrodes of the first part; and a second insulation layer is arranged on the third electrode. The invention further provides a stereoscopic display device using the liquid crystal lens. The liquid crystal lens provided by the invention has the advantages as follows: due to the new liquid crystal lens can, the impedance of the bar electrodes in the liquid crystal lens unit is reduced on one hand and the automatic repair effect is exerted to a certain extent at the same time on the other hand; and the problem of non-uniform voltage distribution in a liquid crystal lens array is radically solved.

Description

technical field [0001] The invention relates to stereoscopic display technology, in particular to a liquid crystal lens and a stereoscopic display device. Background technique [0002] Compared with glasses-type 3D display technology, autostereoscopic display technology has attracted extensive attention because it can objectively get rid of the shackles of glasses and other equipment, and improve viewing comfort and application fields. Among them, the 3D display technology based on the parallax barrier has a very serious loss in brightness, and an ultra-high-brightness backlight source is required to view a relatively ideal 3D effect, which not only increases the power consumption of the entire display device, but also shortens the backlight time. In contrast, the autostereoscopic display technology based on liquid crystal lenses has almost no loss in brightness, and the brightness of the backlight does not need any adjustment when switching between 2D and 3D, which is a mor...
