Display panel, display device, and driving method

A display panel comprising a first liquid crystal cell and a second liquid crystal cell stacked on top of each other, wherein the first liquid crystal cell is located on the light output side of the second liquid crystal cell;

• the first liquid crystal cell comprises a first substrate, a second substrate arranged opposite to the first substrate, and a dye liquid crystal layer located between the first substrate and the second substrate, the first substrate is provided with a viewing angle auxiliary electrode, and the second substrate is provided with a viewing angle control electrode that cooperates with the viewing angle auxiliary electrode;
• the second liquid crystal cell comprises a color film substrate, an array substrate arranged opposite to the color film substrate, and a liquid crystal layer arranged between the color film substrate and the array substrate;
• a first polarizer is provided on the side of the second liquid crystal cell away from the first liquid crystal cell, and a second polarizer is provided on the side of the second liquid crystal cell near the first liquid crystal cell, the light transmission axis of the second polarizer is perpendicular to the light transmission axis of the first polarizer, the first polarizer is a reflective polarizer, a prism structure layer is provided in the first liquid crystal cell and/or the second liquid crystal cell, and the prism structure layer has a light diffusion effect on backlight.
