摘要： Provided are an apparatus and method for driving a 2-dimensional (2D)/3-dimensional (3D) switchable display for improving the quality of image. The apparatus for driving a 2D/3D switchable display includes: an image mode determination unit determining whether input image signals of continuous frames are in a 2D mode or 3D mode; and an over-driving control unit over-driving the input image signal of a current differently according to the determined image mode. According to the apparatus and method, the response time in each of the 2D mode and the 3D mode can be increased, while motion blur and cross-talk effects can be decreased, thereby improving the quality of image.

摘要： A 2D/3D convertible display apparatus and a method of driving the same are provided. The 2D/3D convertible display apparatus includes a liquid crystal display panel, a polarizing panel changing the direction of polarization of an incident light beam according to a signal applied thereto, a panel driver applying a driving signal to the liquid crystal display panel when receiving a vertical synchronization signal and applying a driving signal to the polarizing panel when receiving a stereo synchronization signal, and a synchronization signal generator generating the stereo synchronization signal to allow the panel driver to apply the driving signal to the polarizing panel in both 2D and 3D modes. Accordingly, the driving signal is applied to the polarizing panel in the 2D mode to solve a problem that the polarizing panel is off to cause a defective image to be displayed when the driving signal is not applied to the polarizing panel in the 2D mode.
