Abstract:
In a display apparatus, a data driver converts a first group of image data into a first data voltage based on a first gamma reference voltage during a first period and converts a second group of the image data into a second data voltage based on a second gamma reference voltage during the first period. The data driver converts the first group into the second image voltage during a second period and converts the second group into the first data voltage during the second period. First and second pixel groups receive the first and second data voltages to display first and second gray-scale images, respectively, during the first period, and receive the second and first data voltages to display the second and first gray-scale images, respectively, during the second period. Thus, display quality and viewing angle characteristic of the display apparatus are improved and flicker is prevented.
Abstract:
A liquid crystal display panel includes a pixel having a switching element electrically connected to a gate wiring and a source wiring and a liquid crystal capacitor electrically connected to the switching element. A timing controller receives a mode selecting signal corresponding to an impulsive driving mode, and outputs a first common voltage corresponding to the impulsive driving mode. A common voltage converter converts the first common voltage into a second common voltage of analog type, and outputs the second common voltage to the liquid crystal capacitor. Therefore, in the LCD apparatus operated in an impulsive driving method, a common voltage is selectively applied to the liquid crystal display panel, thus improving a display quality.

Abstract:
An apparatus and a method for controlling a welding robot is disclosed. In the method, an initial welding is performed under initial welding conditions while moving a welding object and a welding torch relatively to each other along a predetermined welding line. Then, a change point at which at least one of the welding conditions should be changed, and a change value of the welding condition, are determined. The welding conditions are changed to the change value at the change point while the welding operation and the relative movement of the welding object and the welding torch are continued. Thus, the welding operation is not stopped during the real-time change of the welding conditions such as welding voltage, welding current, welding speed and the like. Thus, working efficiency and the welding quality are improved, and the discontinuity of the welding bead does not occur.
