An IPS mode LCD device is disclosed in which a common voltage drop and delay is decreased. The LCD includes gate and data lines crossing each other to define pixel regions. Thin film transistors are formed at crossing portions of the gate and data lines. Common lines are parallel with the gate lines and common electrodes project from the common lines parallel with the data lines. Pixel electrodes connected with drain electrodes of the thin film transistors are formed in the pixel regions between the parallel common electrodes. A first common voltage supplying line applies a first common voltage or a second common voltage to a closed circuit formed by grouping the adjacent odd numbered common lines. A second common voltage supplying line applies the second common voltage or the first common voltage to a closed circuit formed by grouping the adjacent even numbered common lines.

An ice dispenser has a duct cap and a controller to control movement of the duct cap. The controller includes a guide, a first control surface, and a second control surface. A first frictional force between the guide and the first control surface is greater than a second frictional force between the guide and the second control surface. The first frictional force controls the duct cap to move at a first rate and the second friction force controls the duct cap to move at a second rate faster than the first rate.

Disclosed is a sequence similarity measuring apparatus and a method of controlling the same. The sequence similarity measuring apparatus using dynamic programming includes: a matrix generating unit for generating a matrix based on the dynamic programming by using two sequences; a normalization unit for calculating a similarity reference value by inputting an element value of a last row/column of the matrix generated by the matrix generating unit into a normalization formula for a given sequence length; and a similarity measuring unit for measuring predefined sequence similarity between the two sequences, based on the similarity reference value calculated by the normalization unit. This makes it possible to easily and correctly achieve similarity comparison between multiple sequences, and thus this technology is expected to be widely utilized in biology/programming application fields.
