Three dimensional image display device having 2D and 3D modes and driving method thereof

摘要

In a 3D image display device and a driving method thereof, a left-eye image and a right-eye image are displayed at a 3D display frequency higher than a 2D display frequency in a 3D mode. The left-eye image or the right-eye image is applied to a data line as data voltages having the same polarity and the same magnitude throughout at least two consecutive frames. A gate-on voltage is applied to a plurality of gate lines crossing the data line sequentially at an interval of a compensation gate-on application time calculated based on a total data delay value.

1. A driving method of a 3D image display device, comprising:
determining whether a display device is operating in a 2D mode for displaying only two-dimensional images or a 3D mode for displaying three-dimensional images; displaying an image at a predetermined 2D display frequency when it has been determined that the display device is operating in the 2D mode; and displaying a left-eye image and a right-eye image at a predetermined 3D display frequency higher than the 2D display frequency when it has been determined that the display device is operating in the 3D mode, wherein the displaying of the left-eye image and the right-eye image includes: applying data voltages representing the left-eye image or the right-eye image to a data line, the data voltages applied to the same pixel having an identical polarity and an identical magnitude throughout at least two consecutive frames; and sequentially applying a gate-on voltage to a plurality of gate lines crossing the data line at an interval of a compensation gate-on application time that is calculated based on a total data delay value, wherein when the left-eye image or the right-eye image is consecutively applied for x number of frames, a margin is provided such that a third time acquired by multiplying a second time acquired by subtracting a total gate delay value from an effective charge time in the 3D mode by x is larger than a first time acquired by subtracting the total gate delay value from an effective charge time in the 2D mode.
