ABSTRACT:
A method for automatically testing display device. The method includes steps of: capturing an image; acquiring a horizontal strip of a to-be-tested image which includes at least a portion of each of the color interval column of the image; comparing a standard deviation A of RGB values of pixels in a vertical sample with a standard deviation B of RGB values of pixels an adjacent vertical sample to obtain samples of each color interval from many samples taken; taking pixels from many vertical samples of each color interval to calculate a mean value of the RGB values of each color interval respectively, determining a color corresponding to each of color intervals, and determining an interval sequence of the to-be-tested image and the code sequence of the color intervals; and determining an image format corresponding to the code sequence according to the image format table which records a plurality of image formats corresponding to the interval sequences of the color intervals of the images.
