Problems solved by technology
The way to achieve narrow viewing angle in the prior art is to add a narrow viewing angle film. When the narrow viewing angle film is placed on the display panel, a narrow viewing angle is realized. When the narrow viewing angle film is removed, a wide viewing angle is realized. When this design is used very inconvenient
For LCD products, some designs set a layer of transparent electrodes on the color film substrate to control the direction of liquid crystal light leakage. This method has great influence on the entire LCD panel design, backlight design, circuit control design, and production process. Difficult, high defect rate; and because an additional electrode is added, it is very unfavorable to LCD display, resulting in poor LCD display afterimage level, light leakage at wide viewing angles, and serious brightness loss at narrow viewing angles, etc.

The invention discloses a display panel and a driving method thereof, and a display device. The display panel comprises: a display substrate, wherein light emitted from a light exiting surface of thedisplay substrate is linearly polarized light; a functional liquid crystal box is located on one side of the light exiting surface of the display substrate, and comprises a first substrate, a liquid crystal molecule layer and a second substrate; a functional electrode layer is located on the side, close to the liquid crystal molecule layer, of the first substrate, and comprises a first electrode group and a second electrode group which are arranged in a first direction in a staggered manner; the first electrode group and the second electrode group each comprise at least two electrodes; a lighttransmittance axis of a functional polarization structure is perpendicular to a polarization direction of the light emitted by the display substrate; the display panel comprises a first display state; in the first display state, a first voltage signal is applied to all the electrodes in the first electrode group, and a second voltage signal is applied to all the electrodes in the second electrodegroup; and the first voltage signal and the second voltage signal are different in size. The display panel can realize narrow-viewing-angle displaying, and is simple in design.
Description
technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel, a driving method thereof, and a display device. Background technique [0002] In the existing display device technology, the display panel is mainly divided into two mainstream technologies of a liquid crystal display panel and an organic self-luminous display panel. Among them, the liquid crystal display panel forms an electric field capable of controlling the deflection of liquid crystal molecules by applying a voltage on the pixel electrode and the common electrode, and then controls the transmission of light to realize the display function of the display panel; the organic self-luminous display panel uses organic electroluminescent materials, When a current passes through the organic electroluminescent material, the luminescent material will emit light, thereby realizing the display function of the display panel. [0003] At present, the vi...
