Abstract
A method of processing three-dimensional (3D) stereoscopic image data is provided that includes comparing the polarity of image data of a present frame with the polarity of image data of a previous frame. The image data of the present frame are compensated according to the result of the comparison. The image data of the present frame is compensated to generate first compensation data, when the polarity of the image data of the present frame is opposite to the polarity of the image data of the previous frame, with respect a reference voltage.
Claims15
A method of processing three-dimensional (3D) stereoscopic image data, the method comprising:
- comparing the polarity of image data of a present frame with the polarity of image data of a previous frame;
- and
- compensating the image data of the present frame according to the result of the comparison by generating first compensation data using a first look-up table (LUT) when the polarity of the image data of the present frame is opposite to the polarity of the image data of the previous frame with respect to a reference voltage,
- wherein the image data of the present frame and the previous frame comprise different ones of left eye image data and right eye image data.
A display apparatus comprising:
- a display panel to display an image;
- a timing controller configured to compare the polarity of image data of a present frame with the polarity of image data of a previous frame and to compensate the image data of the present frame according to the result of the polarity comparison, the timing controller comprising:
- a control signal generator configured to generate a reverse control signal, such that the voltage of the reverse control signal is changed after a one frame period, in a 2D flat image mode, and the voltage of the reverse control signal is changed after a two-frame period, in a 3D stereoscopic image mode;
- and
- a data compensator configured to compensate the image data of the present frame, according to the result of the polarity comparison, which is based on the reverse control signal;
- and
- a data driver configured to convert data provided from the timing controller into a data voltage, to determine the polarity of the data voltage, and to output the data voltage to the display panel,
- wherein the data compensator is further configured to generate first compensation data using a first LUT, when the polarity of the image data of the present frame is opposite to the polarity of the image data of the previous frame, with respect to a reference voltage, in the 3D stereoscopic image.
