摘要： A cover window includes a glass substrate, a polymer film disposed on the glass substrate, an adhesive layer disposed between the glass substrate and the polymer film, a protective layer covering the adhesive layer and the glass substrate, and a light blocking portion disposed on at least one of the glass substrate and the polymer film. The protective layer covers a side surface of the adhesive layer, a side surface of the glass substrate, and one surface of the glass substrate. The cover window has improved strength and reliability.

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.

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.
