Driving method of liquid crystal display device

Abstract

The invention discloses a driving method of a liquid crystal display device. The liquid crystal display device comprises a lower substrate, an upper substrate, and a liquid crystal layer positioned between the lower substrate and the upper substrate, wherein the upper substrate is provided with a first biased electrode and a second biased electrode; the first biased electrode comprises a pluralityof first electrode bars; odd rows of pixel units are respectively covered with the plurality of first electrode bars; the second biased electrode comprises a plurality of second electrode bars; evenrows of pixel units are respectively covered with the plurality of second electrode bars. According to the driving method, through an arrangement way of the biased voltages and a voltage driving way of the upper substrate (namely a colored-film substrate), together with a reverse rotation driving way of the lower substrate (namely an array substrate), switching between wide and narrow view modes is realized; under the premise of maintaining an existing peeping prevention effect, a penetration ratio under the narrow view mode can be increased, and the contrast degree under the narrow view modecan be greatly improved, and the display picture quality of the display device having switchable view angles is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a driving method of a liquid crystal display device. Background technique [0002] Liquid crystal display (liquid crystal display, LCD) has the advantages of good image quality, small size, light weight, low driving voltage, low power consumption, no radiation and relatively low manufacturing cost, and occupies a dominant position in the field of flat panel display. [0003] The current liquid crystal display is gradually developing in the direction of wide viewing angle, whether it is a mobile terminal application, a desktop monitor or a notebook computer. Features. Therefore, in addition to the demand for a wide viewing angle, displays that can be switched or adjusted to a narrow viewing angle mode are gradually developed in situations where anti-peeping is required. The display has a hybrid viewing angle (Hybird Viewing Angle, HVA), which can realize switching...
