Abstract

The invention discloses a display panel, a driving method and a display device. The display panel includes a viewing angle control box, a mirror switching box, a display liquid crystal box, a semi-transparent and semi-reflective film, a first polarizer and a second polarizer arranged in layers. Both the viewing angle control box and the mirror switching box are arranged between the first polarizer and the transflective film and on the same side of the display liquid crystal box, and the second polarizer is arranged on the side away from the first polarizer of the display liquid crystal box. The light transmission axis of a polarizer is parallel to the light transmission axis of the semi-transparent and semi-reflective film, and the light transmission axis of the second polarizer is perpendicular to the light transmission axis of the semi-transparent and semi-reflective film. The viewing angle control box includes a first substrate, a second The substrate and the first liquid crystal layer arranged between the first substrate and the second substrate; the mirror switching box includes a third substrate, a fourth substrate and a second liquid crystal layer arranged between the third substrate and the fourth substrate. The display panel can be switched between wide viewing angle, narrow viewing angle and mirror display.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a driving method and a display device. Background technique [0002] With the continuous advancement of liquid crystal display technology, the viewing angle of the display has been expanded from about 120° to more than 160°. While enjoying the visual experience brought by the large viewing angle, people also hope to effectively protect commercial secrets and personal privacy. Avoid commercial loss or embarrassment caused by information leakage on the screen. Therefore, in addition to the requirement for a wide viewing angle, in many occasions, the display device is also required to have a function of switching between a wide viewing angle and a narrow viewing angle. [0003] In the prior art, a viewing angle control electrode on one side of a color filter substrate (color filter, CF) is used to apply a vertical electric field to the liquid crystal molec...
