Barrier device, auto stereoscopic display using the same and driving method thereof

Abstract

A 3D image display device includes a display panel, a barrier, a controller, and a barrier driver. The barrier includes: a first substrate; a plurality of first electrodes disposed on the first substrate and extended in a first direction; a plurality of second electrodes respectively disposed between adjacent first electrodes; a second substrate opposing the first substrate; a plurality of third electrodes disposed on the second substrate and extended in a second direction crossing the first direction; a plurality of fourth electrodes respectively disposed between adjacent third electrodes; and a liquid crystal layer disposed between the first and second substrates. The barrier driver receives a barrier control signal from the controller, and applies a reference voltage to the first electrodes, the second electrodes, the third electrodes, and / or the fourth electrodes, and applies a liquid crystal driving voltage to one or more other ones of the first to fourth electrodes.

Description

technical field [0001] The present invention relates to a spacer device and a 3D image display device using the same for displaying a 3D image by utilizing binocular parallax. More specifically, the present invention relates to a spacer device and a 3D image display device using the same and capable of changing the shape of the spacer. Background technique [0002] Generally, people perceive the stereoscopic effect physiologically and empirically. In the three-dimensional image display technology, a stereoscopic effect of an object is generated by using binocular parallax, and binocular parallax is a main factor for seeing the stereoscopic effect at a short distance. Stereoscopic images can be viewed through a stereoscopic method that requires glasses or an autostereoscopic method that does not require glasses. [0003] The anaglyph method is divided into an anaglyph method, a polarization method, and a time division method, wherein the anaglyph method involves wearing gla...

[0009] However, although the sawtooth partition improves horizontal resolution, it suffers from a narrow viewing angle

Also, although it can be used for both the portrait mode screen and the landscape mode screen, when the screen is changed to landscape mode while the display mode of the partition is fixed, due to the position of the left eye pixel and the right eye pixel of the display panel, and the position of the opaque and transparent areas of the divider, may not display the 3D image correctly

[0010] For those reasons, it has been difficult to popularize 3D image display devices so far
