  • Publication number: 20090096778
    Abstract: A method of measuring image-sticking of a display device based on a vision model is described. A display device is provided, and a test frame is displayed on the display device. The test frame has a pattern formed by a maximum gray level and a minimum gray level. After burning-in the test frame for a period of time, a gray frame at a medium gray level is displayed on the display device. The test frame, including portions of extreme black and extreme white, leaves image-sticking on the gray pattern at a medium gray level at the same time. Next, an image capture device is used to capture the image-sticking on the display device after burn-in. Finally, a vision model is employed to simulate the human visual perception on the image-sticking and to grade the image-sticking according to the human eye sensitivity for viewing the image-sticking on the display device.
