Abstract
A display apparatus for reducing an afterimage and a driving method thereof are provided. The display apparatus includes a video processor which divides and outputs each of frames constituting the left-eye image and the right-eye image into a plurality of sub-frames which have different sustaining times when the left-eye image and the right-eye image are input; a display unit which displays an image based on the divided sub-frames; and a controller which prevents recognition of at least one sub-frame among the plurality of sub-frames on the basis of the sustaining times of the plurality of sub-frames, thus presenting a clear image.
Claims19
A plasma display panel (PDP) display apparatus using glasses comprising a left-eye shutter and a right-eye shutter which alternately open and close in synchronization with a left-eye image and a right-eye image of a stereoscopic image, the PDP display apparatus comprising:
- a video processor which divides and outputs each of frames of the left-eye image and frames of the right-eye image into a plurality of sub-frames of the left-eye image and a plurality of sub-frames of the right-eye image each of which have a different sustaining time when the left-eye image and the right-eye image are input;
- a display unit which displays an image based on the plurality of sub-frames output by the video processor;
- and
- a controller which prevents recognition of at least one sub-frame of the plurality of sub-frames of the left-eye image and at least one sub-frame of the plurality of sub-frames of the right-eye image based on the sustaining times of the plurality of sub-frames of the left-eye image and the right-eye image.
A method of driving a plasma display panel (PDP) display apparatus using glasses comprising a left-eye shutter and a right-eye shutter which alternately open and close in synchronization with an inputted left-eye image and an inputted right-eye image of a stereoscopic image, the method comprising:
- dividing each of frames of the inputted left-eye images and the inputted right-eye images into a plurality of sub-frames of the left-eye image and a plurality of sub-frames of the right-eye image which have different sustaining times;
- and
- preventing recognition of at least one sub-frame of the plurality of sub-frames of the left-eye image and at least one sub-frame of the plurality of sub-frames of the right-eye image based on the sustaining times of the plurality of sub-frames of the left-eye image and the right-eye image.
A method for reducing afterimage in a stereoscopic image of a display apparatus, the method comprising:
- inputting the stereoscopic image;
- converting the stereoscopic image into a plurality of sub-frame images of a left-eye image and a plurality of sub-frame images of a right-eye image based on a detected synchronous signal, and
- excluding at least one sub-frame of the plurality of sub-frames of the left-eye image and the plurality of sub-frame images of the fight-eye image, wherein recognition of the at least one excluded sub-frame is prevented based on the sustaining times of the plurality of sub-frames.
