摘要： Disclosed are a method and system for evaluating current spreading of a light emitting device. The method includes applying current to a light emitting device and acquiring a luminescence image corresponding to a digital signal, converting the luminescence image into a gray image, and determining the number of pixels having gray levels greater than a set threshold among pixels included in the luminescence image converted into the gray image, as a criterion for determining the degree of current spreading of the light emitting device.The luminescent area of the light emitting device is quantified as an objective value on the two-dimensional plane by using an image processing technique, so that the degree of current spreading in the light emitting device can be evaluated.
