Problems solved by technology

[0005] However, the defect of the first method is that this method needs to prepare an additional louver shielding film and needs to be carried by the user, which causes great inconvenience to the user; the defect of the second method is that this kind of dual-light source backlight system will cause The thickness and cost of the liquid crystal display are all increased, which does not conform to the development trend of light and thin liquid crystal displays; the defect of the third method is that two kinds of electrodes, a wide viewing angle display driving electrode and a viewing angle control electrode, need to be set on the liquid crystal display, which makes the liquid crystal display Aperture ratio decreases, leading to decrease in panel brightness of LCD

Abstract

The invention discloses a display panel, a display device and a driving method thereof.A view angle control electrode is arranged on a second substrate (color filter substrate) of the display panel, and voltage is applied on the view angle control electrode when a narrow view angle is needed, so that an electric field perpendicular to the display panel is generated between the view angle control electrode, a pixel electrode arranged on a first substrate (array substrate) and a common electrode, liquid crystal molecules have dip angle changes in the vertical direction, and the purposes of squint dark state light leakage, contrast decrease, view angle narrowing and narrow-view-angle display are achieved.Therefore, the wide-view-angle mode and the narrow-view-angle mode can be switched by adjusting the voltage applied on the view control voltage.

Description

technical field [0001] The present invention belongs to the field of display technology, and more specifically, relates to a display panel, a display device and a driving method thereof. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) has many advantages such as light and thin, energy saving, no radiation, etc., therefore has gradually replaced the traditional cathode ray tube (CRT) display. Currently, liquid crystal displays are widely used in high-definition digital televisions, desktop computers, personal digital assistants (PDAs), notebook computers, mobile phones, digital cameras and other electronic devices. [0003] At present, liquid crystal displays are gradually developing in the direction of wide viewing angles. For example, portable electronic display devices with wide viewing angles such as mobile terminals, desktop monitors, and notebook computers. screen. However, when it comes to the user's personal privacy and important i...
