Abstract
A 3-dimensional image display device includes a signal controller, a data driver, a display panel, and glasses. The signal controller includes a reference gamma data generator to correct image data. The data driver includes a gray voltage generator to generate a gray voltage based on the corrected image data. The display panel displays left-eye and right-eye images based on a data voltage from the data driver. The lenses of the glasses are controlled by a glasses synchronization signal from the signal controller, to compensate for charging rates of the left-eye and right-eye images.
Claims20
A 3-dimensional image display device, comprising:
- a signal controller including a reference gamma data generator to correct and output image data;
- a data driver including a gray voltage generator to generate a gray voltage according to an output of the reference gamma data generator, and to receive the image data corrected by the signal controller;
- a display panel including a plurality of pixels, the display panel to display a left eye image and a right eye image based on a data voltage output from the data driver;
- and
- glasses including a left-eye lens and a right-eye lens controlled by a glasses synchronization signal from the signal controller, wherein
- the signal controller compensates for a difference of charging rates of the left eye image and the right eye image based on the glasses synchronization signal by applying different lookup tables included in a plurality of lookup tables on the left eye image and the right eye image, respectively, the difference of the charging rates of the left eye image and the right eye image being caused by a polarity inversion driving of the pixels, wherein:
- a polarity of the data voltage applied to the display panel is inversed for predetermined frames,
- one image between the left eye image and the right eye image, applied with the polarity inversion, is an inversion compensation image, and
- another image between the left eye image and the right eye image, applied without the polarity inversion, is a non-inversion compensation image, and wherein
- the inversion compensation image and the non-inversion compensation image are compensated by applying the different lookup tables, respectively.
A controller for a 3-dimensional image display device, comprising:
- a reference gamma data generator to correct image data;
- a gray voltage generator to generate a gray voltage based on the corrected image output from the reference gamma data generator;
- and
- a signal controller to control a display panel to display left-eye and right-eye images based on the gray voltage output from the gray voltage generator, and to control glasses including a left-eye lens and a right-eye lens based on a glasses synchronization signal, wherein
- the signal controller compensates for a difference of charging rates of the left-eye and right-eye images based on the glasses synchronization signal by applying different lookup tables on the left eye image and the right eye image, respectively, the difference of the charging rates of the left eye image and the right eye image being caused by a polarity inversion driving of the pixels, wherein:
- a polarity of the data voltage applied to the display panel is inversed for predetermined frames,
- one image between the left eye image and the right eye image, applied with the polarity inversion, is an inversion compensation image, and
- another image between the left eye image and the right eye image, applied without the polarity inversion, is a non-inversion compensation image, and wherein
- the inversion compensation image and the non-inversion compensation image are compensated by applying the different lookup tables, respectively.
