摘要： An apparatus for inspecting a display panel for defects includes a table which supports the display panel, a laser excitation unit that irradiates a non-display area of the display panel with a point laser beam, a thermal wave detecting unit that generates thermal wave images of irradiated portions of the non-display area, a driving unit, and a control unit. A groove corresponding to an edge of the display panel may be defined in a top surface of the table. A defect, such as a crack, may be detected by comparing a defect pattern obtained from the thermal wave images with a pre-registered defect pattern.

摘要： A foldable display device includes a window. The window includes a first sub window, a second sub window, and an adhesive layer for coupling the first sub window and the second sub window to each other. The first sub window includes a first base layer having light transmittance of 90% or more and a first anti-fingerprint layer disposed on an upper surface of the first base layer, and the second sub window includes a second base layer disposed on the first sub window. A contact angle of a folding area of an upper surface of the first sub window is less than a contact angle of a peripheral area of the upper surface of the first sub window.

摘要： An impact test apparatus includes a base plate having an upper surface on which a specimen is placed, a collision member that collides with the specimen, a dropping unit that drops the collision member from an upper area of the specimen to the specimen and adjusts a height that the collision member drops, a velocity measurement unit that measures a collision velocity of the collision member when the collision member collides with the specimen, and an evaluation unit that produces a representative value that is a collision velocity at which a probability of breakage of the specimen is about 50%, and evaluates an impact resistance of the specimen based on the representative value.
