Abstract: A method for fabricating a liquid crystal display (LCD) device includes forming a gate electrode and a common electrode line on a first substrate; forming a first insulating layer on the gate electrode; forming an active layer and source/drain electrodes on the first insulating layer; forming a second insulating layer on the source/drain electrodes; forming a photosensitive layer on the second insulating layer; forming a first contact hole, a second contact hole, a first trench and a second trench in the second insulating layer; forming a conductive layer on the photosensitive layer and in the first and second contact holes and the first and second trenches; lifting-off the photosensitive layer to form a pixel electrode electrically connected to the drain electrode through the first contact hole in the first trench and a common electrode electrically connected to the common electrode line through the second contact hole in the second trench; and attaching the first substrate to a second substrate.

Abstract: A system for controlling a linear compressor, generates freezing force as a piston reciprocates according to rotation of a motor which receives alternating current power through a triac. The system includes a controller which moves up or delays a trigger signal corresponding to an absorption cycle or a compression cycle, such that the center point of the piston reaches a resonant point when a current and a phase difference of the motor deviate from predetermined ranges.

Abstract: A display apparatus has a cooling means, including a display panel having a first substrate and a second substrate which are spaced from each other. A chassis member is placed at the rear surface region of the display apparatus and is formed to surround sides and a front edge region of the display panel. With this configuration, the display apparatus with a cooling means effectively discharges heat from the display panel, thereby cooling the entire display panel.

Abstract: A method for fabricating a color filter substrate for a liquid crystal display device having a RGBW pixel structure, wherein a white sub-color filter layer is formed during a process of forming a planarization layer with a step, and a spacer pattern is formed on the white sub-color filter layer for compensating for the step of the planarization layer.

Abstract: Disclosed is an electro-absorption optical modulator using a semiconductor device. The optical modulator makes use of a change in light absorption caused by displacement of an absorption curve depending on a bias voltage applied to the device. Here, a level of the light absorption depending on the bias voltage is expressed as a transfer function of output light to the applied bias, and the transfer function has a non-linear profile due to a characteristic of a material. Unlike signal modulation of a digital optical communication system, an analog optical transmission system can be subjected to deterioration in performance, because the non-linear characteristic of the transfer function for the optical modulator generates signal distortion when an electrical signal is converted into an optical signal. The typical optical modulator has an absorption layer constituted of quantum wells having the same width.
