Abstract: An apparatus and method for inspecting a glass substrate. The apparatus for inspecting a glass substrate includes a stage configured to support the glass substrate, a first light source for irradiating light onto a surface of the glass substrate at a first angle, a first camera for capturing scattered light of the light irradiated from the first light source, a second light source for irradiating light onto the surface of the glass substrate at a second angle greater than the first angle, a second camera for capturing reflected light and scattered light of the light irradiated from the second light source, and a defect detection unit for detecting a defect of the glass substrate using a first image provided by the first camera and a second image provided by the second camera.

Abstract: An image sticking compensation device includes: a deterioration calculator which calculates deterioration data of a current frame based on input image data and sensing frequency information which are received from a timing controller; an accumulator which accumulates the deterioration data and generates age data in which the deterioration data is accumulated; and a compensator which determines a grayscale compensation value corresponding to the age data and an input grayscale value of the input image data, and outputs age compensation data by applying the grayscale compensation value to the input image data. The sensing frequency information includes a frequency of the current frame, and the deterioration data varies in accordance with the frequency of the current frame.
