PURPOSE: A method for displaying a video signal dithered by related masks and a video display apparatus is provided to minimize the deterioration of gradation of a video signal by performing color processing after dithering the video signal. CONSTITUTION: In a method for displaying a video signal dithered by related masks and a video display apparatus, a video processor(129) processes a video signal. A video output part(135) displays the processed video signal on a display unit A first dithering part dithers the video signal by using a first mask. A color processor performs color processing of the video signal. A broadcast processing unit(120) processes a broadcast signal outputted from a broadcasting receiver(110).

PURPOSE: A liquid crystal display apparatus, and a driving method of the liquid crystal display apparatus are provided to prevent after image on DID screen by reducing the stress of liquid crystals. CONSTITUTION: In a liquid crystal display apparatus, a panel portion comprises at least one pixel. A controller(200) inserts gray data into a sub-pixel. A frame counter(210) counts a synchronizing signal. The frame counter detects the period of the frame. A mask generating unit(220) generates a mask from each frame. A masking part(230) masks the mask the gray data of the RGB data in the image frame.
Abstract:
A display device capable of automatically adjusting a display-to-face angle and a driving method thereof are provided to store and adjust the display-to-face angle set by a user according to a specific condition, thereby enabling a user to use the display device in an optimum state and improving the convenience of a user. A storage(140) stores information about a display-to-face angle. A driving unit(120) adjusts an angle of a display(110) by driving the display. A controller(150) controls the driving unit so as to adjust the angle of the display based on the information about the display-to-face angle. After adjusting the angle of the display to an initial angle, the driving unit is controlled so as to adjust the angle of the display to the display-to-face angle pre-stored in the storage.
Abstract:
An apparatus and a method for correcting a disparity vector are provided to prevent the distortion of an image in advance by adaptively correcting a disparity vector of a pixel positioned at the edge of an image considering similarity or correlation between the pixel and a surrounding vector. A reliability determining unit(210) determines whether the first disparity vector estimated for the current pixel has reliability. If the first disparity vector has no reliability, the reliability determining unit(210) determines whether the second disparity vector estimated for the next pixel, which is positioned on a horizontal line of the current pixel, has reliability. A correcting unit(220) uses the second disparity vector as a corrected disparity vector of the current pixel if the second disparity vector has reliability and the current pixel is similar to the next pixel. A multiplexer(230) selects and outputs one of the first disparity vector and the second disparity vector as the final disparity vector of the current pixel according to the determined result of the reliability determining unit(210).
