Array substrate, display device and driving method

Abstract

The invention provides an array substrate, a display device and a driving method, and relates to the field of the display technology. The array substrate comprises an N scanning signal line, an N+1 scanning signal line, an M data signal line, a pixel unit, a first switch unit, a second switch unit and a third switch unit; the pixel unit comprises first sub-pixels and second sub-pixels; a control end of the first switch unit is electrically connected with the N scanning signal line, an input end of the first switch unit is electrically connected with the M data signal line, and an output end of the first switch unit is electrically connected with first pixel electrodes; a control end of the second switch unit is electrically connected with the N scanning signal line, an input end of the second switch unit is electrically connected with the M data signal line, and an output end of the second switch unit is electrically connected with second pixel electrodes; and a control end of the third switch unit is electrically connected with the N+1 scanning signal line, an input end of the third switch unit provides input signals, and an output end of the third switch unit is electrically connected with the second pixel electrodes. The array substrate, the display device and the driving method have the advantage that a visual angle of a liquid crystal display can be increased. The invention is applicable to designing and manufacturing display devices.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a display device and a driving method. Background technique [0002] A liquid crystal display device controls light transmittance through liquid crystals using an electric field to display images. Liquid crystal display devices are roughly classified into a vertical electric field driving type and a horizontal electric field driving type according to the direction of an electric field for driving liquid crystals. In the vertical electric field driven liquid crystal display device, a common electrode and a pixel electrode are arranged opposite to each other on the upper and lower substrates, and a vertical electric field is formed between the common electrode and the pixel electrode to drive the liquid crystal. In the horizontal electric field driven liquid crystal display device, a common electrode and a pixel electrode are arranged on the lower subs...

Problems solved by technology

[0003] Although the horizontal electric field type liquid crystal display device has the advantage of a larger viewing angle than the vertical electric field type liquid crystal display device, as the size of the liquid crystal display device becomes larger and larger, the horizontal electric field type liquid crystal display device cannot meet people's requirements for a wide viewing angle, especially It is a widescreen liquid crystal display device of 40 inches or more
