Abstract
Provided is a spot detection device including an imager configured to capture a display panel displaying a first image of a first grayscale and a second image of a second grayscale different from the first grayscale and generate image data, and a spot detector configured to receive the image data from the imager in order to detect a spot. The image data includes first image data obtained by capturing the first image, second image data obtained by capturing the second image, and a plurality of third image data obtained by capturing portions of the first image.
Claims20
A spot detection device comprising:
- an imager configured to capture a display panel displaying a first image of a first grayscale at a first angle and a second image of a second grayscale different from the first grayscale and generate a plurality of image data;
- and
- a spot detector configured to receive the plurality of image data from the imager in order to detect a spot,
- wherein the plurality of image data comprises first image data obtained by capturing a whole of the first image, second image data obtained by capturing a whole of the second image, and a plurality of third image data obtained by capturing portions of the first image at second angles different from the first angle, respectively.
A display device comprising:
- a display panel;
- a first printed circuit board electrically connected to the display panel;
- and
- a memory mounted on the first printed circuit board, wherein the memory stores spot information detected based on first image data obtained by capturing a whole of a first image of a first grayscale displayed on the display panel at a first angle, second image data obtained by capturing a whole of a second image of a second grayscale different from the first grayscale displayed on the display panel, and a plurality of third image data obtained by capturing portions of the first image at second angles different from the first angle, respectively.
A spot detection method comprising:
- capturing a whole of a first image of a first grayscale displayed on a display panel at a first angle to generate first image data;
- capturing a whole of a second image of a second grayscale different from the first grayscale displayed on the display panel to generate second image data;
- capturing portions of the first image at second angles different from the first angle, respectively, to generate a plurality of third image data;
- and
- detecting a spot by the first image data, the second image data, and the plurality of third image data.
