ABSTRACT:
A liquid crystal display (LCD) is disclosed in which adjacent pixels having the same gray level are supplied with different magnitudes of data voltages, thereby increasing the viewing angle of the LCD. A voltage producing circuit produces two groups of gray voltages in which the magnitude of the gray voltages in the two groups are different for the same gray level. The two sets of gray voltages are delivered to the pixels by data drivers connected to left and right data lines. The pixels are arranged in matrix form and data lines are arranged along the columns. For each column, two data lines are assigned, one on the left and the other on the right. The left data lines are connected to one data driver and the right data lines are connected to another data driver. The pixels are connected so that if a pixel is connected to the left data line, then the row and column adjacent pixels are connected to the right data line. Because the adjacent pixels are supplied with different data voltages corresponding to the same gray level, the viewing angle and characteristics of the liquid crystal display are improved.
