摘要:
A high-precision displacement measurement device and linear or rotational displacement measurement method using a unit displacement sensor based on a confocal theory. This device is simpler in construction, lower in cost and superior in resolution to other displacement measurement devices, and is capable of measuring a much wider area than other measurement equipment. The present device is adapted to project a spot of light from a light source on an object whose displacement is to be measured and measure a relative displacement of the object from a displacement of the projected light spot. To this end, the unit displacement sensor includes a transmission lens for transmitting a divergent beam of light emitted from the light source through a slit or pinhole with a certain size, a collimating lens for collimating the light beam transmitted through the slit or pinhole, an object lens arranged between the collimating lens and the object, a beam splitter for splitting a beam of light, reflected from the object to the transmission lens, according to a wavelength, and a photodetector for detecting a light intensity of the light beam split by the beam splitter. A piezoelectric actuator is provided to finely move the unit displacement sensor so as to always maintain optical signals detected by the photodetector at the maximum intensity.

Disclosed is a substrate alignment apparatus capable of performing coarse and fine alignments of a substrate in a progressing route to remove or reduce an alignment error between the substrate and a pattern roll. The coarse alignment may be performed by moving a frame using a stage when the alignment error is relatively large, and the fine alignment may be performed by moving subsidiary rollers of a roller unit relative to a main roller of a roller unit when the alignment error is relatively small. An example substrate alignment apparatus may include a frame and a roller unit rotatably fixed to the frame to support a substrate, wherein the roller unit includes a main roller, and at least one subsidiary roller fixed to the main roller such that the at least one subsidiary roller can move relative to the main roller to align the substrate.

Disclosed herein are a color filter having a black matrix and an apparatus and method of manufacturing the same. The method may include applying an organic film to a substrate, forming a pattern on the organic film by applying pressure to the organic film with a mold having prominences and depressions, and forming a black matrix by applying an ink to the pattern of the organic film. The formation of the black matrix may be achieved by a roll to roll method. The black matrix is easily formed by carrying out imprinting and printing on the organic film applied to the substrate. The black matrix may have a fine line width of a nano level by imprinting and printing. Further, since the black matrix is formed by the roll to roll method, material costs may be reduced and the color filter may be manufactured at a relatively high speed.
