Abstract
The present invention relates to an image display apparatus. The image display apparatus according to an embodiment of the present invention includes a display having an organic light-emitting diode (OLED) panel, and a controller to control the display, wherein in response to an input image being a video, when variation a variation in a level of color information of a first pixel data corresponding to a first pixel in the input image is within a predetermined range, and a level of brightness information of the first pixel data is equal to or higher than a first level, the controller detects the first pixel as a pixel in a static area, and decreases the level of brightness of the first pixel data.
Claims20
An image display apparatus, comprising:
- a display having an organic light-emitting diode (OLED) panel;
- and
- a controller to control the display,
- wherein in response to a first input image being a video, when a variation in a level of color information of first pixel data corresponding to a first pixel in the first input image is within a predetermined range, and a level of brightness information of the first pixel data is equal to or greater than a first level for a particular period, the controller detects the first pixel as a pixel in a static area, and decreases the level of brightness of the first pixel data, and
- wherein in response to a second input image being a video, when a level of color information of second pixel data corresponding to a first area in the second input image is changed, a variation in the level of the color information of the second pixel data is outside of the predetermined range, and a brightness difference between the first area and a surrounding area of the first area is equal to or greater than a predetermined value, the controller detects the first area as a non-static area, and does not decrease level of brightness of pixel data in the first area.
An image display apparatus, comprising:
- a display having an organic light-emitting diode (OLED) panel;
- and
- a controller to control the display,
- wherein when a first input image is a video, the controller determines whether a first pixel is a pixel in a static area based on color information and brightness information of first pixel data corresponding to the first pixel in the first input image;
- when the first pixel is the pixel in the static area, the controller decreases a brightness level of the assigned first pixel data, and
- wherein in response to a second input image being a video, when a level of color information of second pixel data corresponding to a first area in the second input image is changed, a variation in the level of the color information of the second pixel data is outside of a predetermined range, and a brightness difference between the first area and a surrounding area of the first area is equal to or greater than a predetermined value, the controller detects the first area as a non-static area and does not decrease level of brightness of pixel data in the first area.
