Provided is a flexible electrophoretic display. The flexible electrophoretic display includes a grayscale representation unit for representing grayscales in unit areas using reflection and transmission; upper and lower electrodes for applying a voltage to the grayscale representation unit; and a plurality of colored particles formed on the upper electrode for representing color. The upper electrode is formed of a transparent conductive material. External incident light is reflected by the colored particles formed on the upper electrode for color implementation by the flexible electrophoretic display. Thus, a compact, flexible electrophoretic display capable of displaying a high-definition image with multi-color and multi-gradation can be implemented by using multi-colored particle layers formed of metallic nano-particles.

A method and apparatus for generating discriminant functions for distinguishing obscene videos by using visual features of video data, and a method and apparatus for determining whether videos are obscene by using the generated discriminant functions, are provided. The method of generating discriminant functions includes: creating a first frame set by extracting a predetermined number of frames for each video data unit from a group of video data classified as obscene or non-obscene, and creating a second frame set by selecting the frames; generating a frame based discriminant function by extracting visual features of frames of the second frame set, and then generating a first discriminant value by determining whether each frame of the first frame set contains obscene video data; generating a group frame based discriminant function by extracting visual features of a group of frames of the first frame set, and then generating a second discriminant value by determining whether the frames of the group contain obscene video data; and generating a synthetic discriminant function by using the first and second discriminant values as a representative value of the video data. Accordingly, obscene video data stored in a computer system can be automatically and accurately distinguished.

Disclosed is a method for manufacturing a thin film transistor LCD device, in which a counter and a gate bus line are made in a single photolithography process, and a channel of a thin film transistor, a source electrode, a drain electrode, ohmic contacts for the source and drain electrodes are made in a single photolithography process. The method involves the steps of forming a first photoresist layer on said deposited metal layer for the gate bus line; exposing said first photoresist layer to a scanning light, so that the portion of the first photoresist layer disposed over a counter electrode region for forming said counter electrode may be partially lightened; patterning said first photoresist layer so that an area of the metal layer for the gate bus line lying under the partially lightened portion of the first photoresist layer may not be exposed; patterning said metal layer for the gate bus line by using said patterned first photoresist layer as a barrier layer so that said counter electrode region and a gate bus line region may be defined; patterning said transparent conductive layer for the counter electrode by using said patterned metal layer as a barrier layer so that said counter electrode may be formed; patterning said metal layer for the gate bus line by using said patterned first photoresist layer as a barrier layer so that said gate bus line may be formed.
