Title:
DISPLAY APPARATUS AND METHOD FOR PREVENTING IMAGE BURN-IN THEREOF
Document Type and Number:
Japanese Patent JP2023093337
Kind Code:
A
Abstract:
To provide a display apparatus and a method for preventing image burn-in thereof.SOLUTION: A display apparatus is provided, which includes a display panel and a display controller. The display controller calculates an image average brightness of each image in a video signal. When an absolute difference between a first image average brightness of a current image in the video signal and a second image average brightness of a previous image in the video signal is smaller than a predetermined value, the display controller activates a timer to obtain a timer value. When the timer value reaches a first duration, the display controller reduces brightness of each pixel in the current image of the video signal displayed on the display panel by a first ratio. When the timer value reaches a second duration, the display controller reduces the brightness of each pixel in the current image of the video signal displayed on the display panel by a second ratio. The second duration is longer than the first duration, and the second ratio is higher than the first ratio.SELECTED DRAWING: Figure 3
