A display driving circuit and method is capable of minimizing the residual image of a display panel as well as consumption electric current. The display driving circuit generates driving signals corresponding to valid data and black data and transmits the driving signals to a display panel, and includes N data selection switches (where N is the integer), N buffers, N buffer output selection switches, and multiple charge sharing switches. The N data selection switches select one of the valid data and the black data. The N buffers buffer the signal selected by the respective data selection switches. The N buffer output selection switches switch outputs of the buffers to output the respective driving signals. The multiple charge sharing switches connect the neighboring pairs of the driving signals.

Disclosed is a source driver integrated circuit with an improved slew rate by disposing a switching unit, which operates as a resistance component during display driving, before the feedback line of an output buffer. According to the source driver integrated circuit with an improved slew rate, a switching unit, which operates as a resistance component when a signal is transferred, is disposed in the feedback loop of an output buffer, so that the resistance component is not shown to a panel load, thereby improving the slew rate of an output signal. In addition, the improved slew rate makes it possible to easily implement an image through a display.

Embodiments of the invention include a megasonic energy cleaning apparatus that has the ability to rotate the wafer to be cleaned, as well as rotate the cleaning probe during the cleaning process. Rotating the cleaning probe while the wafer is being cleaned is effective to increase the cleaning action of the apparatus while also minimizing damage to the wafer. Curved grooves, such as a spiral groove, can be etched into the cleaning probe to minimize forming harmful waves that could potentially cause damage to the wafer surface or to structures already made on the surface. Using a cleaning probe having a curved groove while also rotating the cleaning probe effectively cleans particles from a wafer while also limiting damage to the surface of the wafer.

A method of removing offsets between channels of a liquid crystal panel is provided. The method includes: alternately arranging first type output buffers and second type output buffers for driving the pixels in units of at least two rows of the pixels; and arranging the first type output buffers and the second type output buffers in units of at least two columns of the pixels so that the output buffers with types opposite to those of previous two columns are arranged. The second type output buffers are embodied by switching connections among the differential transistors and connections among the load transistors in the first type output buffers.
