METHOD FOR DETECTING DOT DEFECTS IN FLAT DISPLAY PANEL

摘要

A method for detecting dot defects in a flat display panel is provided to effectively and consistently detect the dot defects through automation and more exactly detect the dot defects by a luminance calibration process. A method for detecting dot defects in a flat display panel includes the steps of: obtaining an image for each color pattern by using an imaging device(102); performing calibration for the obtained image(104); detecting a dot position for at least one of the color patterns(106); and detecting the dot defects by comparing a luminance value of dots with a reference value. The step of detecting the dot defect further includes a step of: measuring luminance by including at least one line of pixels constituting an adjacent dot opposite to a high dot adjacent to a testing dot when the dot adjacent to the testing dot is the high dot.
