Abstract:
A method of manufacturing an LCD comprising, preparing a liquid crystal panel which comprises a substrate assembly and a polarizing plate, wherein the polarizing plate is attached to the substrate assembly, disposing a gas injecting part towards the plate surface of the liquid crystal panel, while the gas injecting part is exposed to atmospheric conditions, and applying a pressure to the plate surface of the liquid crystal panel by injecting gas through the gas injecting part. With this configuration, the present invention provides a method to remove bubbles between the polarizing plate and liquid crystal panel without the use of a chamber.
Abstract:
A noise damping device of a rotation driving apparatus includes a housing; and at least one rotating disk installed to be rotated by a driving source within the housing. The rotating disk and the housing are assembled to satisfy the following Equation &dgr;m
Abstract:
A polygonal mirror assembly is provided with a vibration absorption. The polygonal mirror assembly includes a motor and a polygonal mirror rotatably installed around the rotation shaft of the motor. The polygonal mirror is provided with a plurality of reflective facets. The vibration absorption device is provided for absorbing rotational vibration due to the eccentric mass of the polygonal mirror, by elastically moving in the radial direction of the polygonal mirror. Therefore, the linearity of a scan line scanned from the laser scanning unit to the photoreceptor medium can be maintained.
Abstract:
An automatic disk discriminating method and an apparatus therefor are disclosed for use in an optical disk system. A triangular wave signal generator generates a triangular wave signal for searching for a focus point by moving a objective lens in relation to the optical disk. A window signal generator generates a window signal by comparing the triangular wave signal with a predetermined level. A disk discriminator discriminates the disk type of the optical disk by comparing the signal obtained when light from the objective lens is focused on a recording surface on the optical disk, with the window signal. Accordingly, the disk type of the optical disk is automatically discriminated during focus controlling using the distance between the disk recording surface and the objective lens of the optical pick-up.
