摘要:
Provided are a surface inspection apparatus and method capable of detecting foreign materials on the surface of a substrate, and a slit coater having the surface inspection apparatus. In the surface inspection apparatus, a slit lighting unit irradiates slit-shaped light. An optical system splits the slit-shaped light into two beams traveling along two different paths, is incident upon a subject, and extracts an interference image caused by combination of the two beams reflected from the subject. An imaging device captures the interference image to output an image signal. An analysis unit acquires a luminance value of the image signal, analyzes the luminance value in real time, and determines whether or not foreign materials are present.

Provided are a method of manufacturing an organic light emitting display apparatus, a surface treatment device for an organic light emitting display apparatus, and an organic light emitting display apparatus. To easily form organic emissive layers, the method includes: forming a first electrode on a substrate; forming on the first electrode a pixel defining layer having openings that expose predetermined portions of the first electrode; forming a charge carrying layer on the pixel defining layer and the first electrode exposed through the openings; hydrophobically treating portions of a surface of the charge carrying layer selectively, wherein the portions do not correspond to the openings, using a laser; forming organic emissive layers on the charge carrying layer; and forming a second electrode on the organic emissive layers so as to be electrically connected with the organic emissive layers.

A delamination apparatus includes a stage, a first roll unit, a gripper, and a second roll unit. The stage includes a peripheral area and a substrate area. An edge of a donor film is attached at the peripheral area. An acceptor substrate, laminated at on the donor film, is disposed at the substrate area. The first roll unit is disposed on the donor film, moves in a lengthwise direction of the acceptor substrate. The gripper is disposed on the donor film, and is configured to separate the edge of the donor film from the stage so as to cause the donor film to contact the first roll unit. The second roll unit is disposed on the stage, contacts the donor film which contacts the first roll unit, and delaminates the donor film from the acceptor substrate by moving in the lengthwise direction with the first roll unit.
