Embodiment Construction

[0026] Exemplary embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] FIG. 1 schematically shows a stereoscopic image display device according to a first exemplary embodiment of the present invention.

[0028] The stereoscopic image display device includes a controller 100 , a barrier driver 210 , a barrier 220 , a display panel driver 310 , a display panel 320 , a backlight 420 and a backlight driver 410 .

[0029] The controller 100 receives image data DATA, a horizontal synchronous signal Hsync, and a vertical synchronous signal Vsync, it generates control signals and data signals, and it transmits the generated control and data signals to the barrier driver 210, the display panel driver 310, and the backlight driver. 410.

[0030] The display panel 320 uses a liquid crystal display panel and includes a plurality of display units 321 and 322 . The display panel 320 is formed with columns each having a plu...

Abstract

A driving method of a stereoscopic image display device having the same resolution as a 2D image and capable of minimizing crosstalk is provided. The driving method includes driving a display panel having first and second display units and simultaneously displaying first and second images having different recognizable viewing angles, and arranging barriers corresponding to the display panel for intercepting or transmitting light. First, during a first time period when images are not displayed, a first data signal corresponding to a first image is written on the first display unit, and a second data signal corresponding to a second image is written on the second display unit superior. Subsequently, during a second time period, the first and second images are displayed by driving the barrier to the first format during the second time period so that the barrier transmits light. Then, the second data signal is written on the first display unit and the first data signal is written on the second display unit during a third period of time when an image is not displayed. Finally, during a fourth time period, the first and second images are displayed by driving the barrier to a second format different from the first format such that the barrier transmits light.

Description

technical field [0001] The present invention relates to a stereoscopic display device and a driving method thereof, and more particularly, to a stereoscopic display device using a barrier and a non-emissive display panel and a driving method thereof. Background technique [0002] Generally, people perceive stereoscopic effects both physiologically and empirically. In a three-dimensional image display technology, a stereoscopic effect of an object is produced by using binocular parallax, which is a main factor for recognizing a stereoscopic effect at a short distance. [0003] Stereoscopic images are viewed using a method that requires wearing glasses and a method that does not require wearing glasses. [0004] Methods that generally do not require wearing glasses include: a lenticular method in which a lenticular plate having an array of vertically aligned lenticular lenses is formed in front of an image plate; and a parallax barrier method in which a barrier is used to sep...
