Disclosed is a method that gives a priority service to enable a subscriber with an urgent message to call another subscriber who is already engaged in a telephone conversation, regardless of the reservation order, and sends an interrupt tone regularly to the target subscriber as a notification that he has a priority reservation and the subscriber engaged in the telephone conversation can link himself with the priority subscriber without having to cut off the current telephone conversation. The m...

An adaptive equalizer includes a recording density detector for calculating a recording density reference value by obtaining the track radius using input track information, a reference tap coefficient storage portion for storing the reference tap coefficient obtained according to the channel impulse response at the lowest density position, a tap coefficient controller for obtaining a tap coefficient according to the recording density using the recording density reference value on the basis of th...

A liquid crystal display (LCD) has a plurality of pixels, each having an aperture region. A LCD display element includes a shorting metal formed outside of the pixel aperture region for converting defective pixels into black defects. The shorting metal is formed from the same material used in, and during the same manufacturing step of, forming the TFT gate electrode. Therefore, the pixel aperture ratio is not reduced and subsequent steps to form the shorting metal are unnecessary.

A thin film transistor-liquid crystal display (TFT-LCD) and a method of manufacturing the same prevent a short by forming a pixel electrode and a data line on different layers, and enhance the resultant image produced by the TFT-LCD by forming a passivation layer at a lower pixel electrode. To form this TFT-LCD, a gate electrode and an adjacent gate electrode are formed on a substrate. A gate insulating layer is then deposited on both the gate electrode and the adjacent gate electrode and an amo...

LCD displays include a substrate, spaced apart data lines on the substrate, and spaced apart gate lines on the substrate that intersect the spaced apart data lines to define an array of display elements. A display electrode and a reference electrode are provided in each display element. The display electrode includes display electrode fingers. The reference electrode includes reference electrode fingers that are spaced apart from the display electrode fingers. A reference electrode line extends ...

A conductive light shading film of a liquid crystal display is electrically connected to a pixel electrode. By connecting the light shading film to the pixel electrode, the light shading film will have the same voltage as the pixel electrode, and can thereby reduce parasitic capacitance and voltage variations on the pixels. The light shading film preferably includes a plurality of conductive light shading lines. The conductive light shading lines can be formed from the same patterned conductive ...

A method for signal degradation alarm detection in a digital microwave system, includes the steps of: summing code violation values from cells of a given buffer except for one of the cells currently indicated in the given buffer to calculate a code violation sum value of a corresponding provision, and setting a code violation limit value to a previously defined value; comparing the code violation sum value with the code violation limit value; setting a signal degradation alarm flag to detect an ...

A plurality of gate lines extending in a horizontal direction are formed on an insulating substrate, and a data line is formed perpendicular to the gate line thereby defining a pixel of a matrix array. Pixel electrodes receiving image signals through the data line are formed in a pixel, and a thin film transistor having a gate electrode connected to the gate line, a source electrode connected to the data line, and a drain electrode connected to the pixel electrode is formed on the portion where ...
