Filed: 2002-12-28
Abstract: PURPOSE: A liquid crystal display device and a method for driving the same are provided to increase the charge voltage of the liquid crystal cell by charging the auxiliary pixel signal before the main pixel signal, thereby improving the response speed of the liquid crystal. CONSTITUTION: A liquid crystal display device includes a liquid crystal panel(12), a gate driver(14), a data driver(16), a data modulator(20) and a timing control block(18). The liquid crystal panel(12) is provided with a liquid crystal cell for charging the auxiliary pixel signal and the main pixel signal supplied to the data line through the thin film transistor in response to the scan signal supplied to the gate line. The gate driver(14) generates the scan signal and supplies the generated scan signal to the gate line. The data driver(16) converts the modulation pixel data into an auxiliary pixel signal in the form of analog and supplies the pixel data to the data line. The data modulator(20) modulates the pixel data of the current frame by comparing the pixel data of the previous frame with the pixel data of the current frame. And, the timing control block(18) supplies the aligned pixel data modulated from the data modulator(20) and the pixel data of the current frame inputted from the outside as well as controls the driving timing of the gate driver(14) and the data driver(16).

Title: Method for filtration of copper electrolyte solution
IPC: B01D37/02
Filed: 2001-04-23
Abstract: The present invention provides a filtration method of copper electrolyte that can remove minute electrolytic by-products and dirt and may improve filtration efficiency by improving a conventional filtration method, the so-called precoating method. In a filtration method of copper electrolyte for removing electrolytic by-products and dirt which affect copper electrolysis, by passing copper electrolyte through a filter element precoated with a filtering aid, in the present invention, a precoated layer of a filtering aid is formed on a filter element in advance. Activated carbon preliminary treatment solution containing powdery activated carbon is passed through the filter element formed with the precoated layer, and is also circulated until no powdery activated carbon leaks from an outlet of the filter element, thus forming a powdery activated carbon layer on the precoated layer. Subsequently, the copper electrolyte is passed through for filtration.

Abstract: PURPOSE: A method for stabilizing the output power of a wireless communication terminal is provided to compare a reference power limit value with an output power of an access probe, and to compensate for a difference between the two power values when the difference is less than a threshold value, thereby realizing smooth communication between a wireless communication terminal and a base station. CONSTITUTION: A wireless communication terminal detects the power of an access probe to communicate with a base station(401). The terminal compares the detected power of the access probe with a reference power limit value(402). The terminal decides whether the detected power is different from the reference power limit value at more than a threshold value(403). If so, the terminal does not compensate for the power of the access probe(404). If the power is not different from the reference power limit value at more than the threshold value, the terminal compensates for the power of the access probe(405).

Abstract: PURPOSE: A spin etching apparatus is provided to improve the uniformity of etching by using modifiable nozzles according to the size of a wafer. CONSTITUTION: A substrate processing apparatus includes a spin chuck and a spraying part. The spin chuck(112) is used for rotating a substrate at high speeds. The spraying part(130) is used for spraying liquid onto a surface of a substrate. The substrate is loaded on the spin chuck. A plurality of nozzles(132a,132b,132c,132d) are installed on the spraying part to spray chemicals onto a plurality of portions of the substrate. A nozzle moving part(140) is used for transferring the nozzles from a stand-by position to a spraying position. The number of the nozzles is modified according to the substrate size. The intervals between the nozzles are capable of being controlled.
