Abstract: An LCD with switchable viewing angle includes a first substrate, second substrate, and a liquid crystal layer. The first substrate is provided with a first electrode and a first alignment film thereon. The second substrate is provided with a second electrode, a third electrode and a second alignment film thereon. The liquid crystal layer is disposed between the first alignment film and the second alignment film, and includes a plurality of liquid crystal molecules. All of the liquid crystal molecules in the liquid crystal layer are tilted at the same pretilt angle relative to the alignment films. When no bias voltage is applied to the first electrode, the LCD shows a narrow viewing angle; and when a bias voltage is applied to the first electrode, the LCD shows a wide viewing angle.

Abstract: A liquid crystal display apparatus includes M data lines arranged in columns, N scanning lines arranged in rows, and pixels determined by intersection of the M data lines and the N scanning lines. M and N are integers greater than 1. The N scanning lines are divided into 2K scanning line groups; K is an integer greater than or equal to 1; and the scanning lines in each scanning line group are connected with pixels having the same polarity. The liquid crystal display apparatus further includes: 2K driving components, each of which corresponding to one scanning line group and being configured to provide a plurality of levels of outputs, each level of outputs being connected with one scanning line in the scanning line group to activate the scanning line. Thus, power consumption can be saved effectively.
