Abstract
A display panel is provided, including an organic electroluminescent device including an anode layer, a liquid crystal cell on a light exit side of the organic electroluminescent device. The liquid crystal cell includes a liquid crystal layer, a linear polarizer on a side of the liquid crystal cell facing away from the organic electroluminescent device and configured to convert ambient light into a first polarized light, and an electrode assembly configured to control deflection of liquid crystal molecules in the liquid crystal layer to convert reflected light from the anode layer into a second polarized light. A second polarization direction of the second polarized light is different from a first polarization direction of the first polarized light. The display panel may decrease the intensity of reflected light perceived by the user when viewing the displayed image in an ambient environment.
