Abstract
An OLED display panel, a display device, and a display system. The OLED display panel comprises a base plate, first OLED display elements arranged in an array on a side of the base plate, and a first photochromic layer arranged on a side of the first OLED display elements. The first photochromic layer comprises first stripe shaped photochromic bodies and first stripe shaped openings arranged periodically and alternately, and is switchable between a transparent state and an opaque state. When the first photochromic layer stays in the opaque state, the first photochromic layer enables the OLED display panel to realize 3D display on the side where the first photochromic layer is arranged. 2D and 3D display modes are realized on a side of the display panel, which improves user experience and has a low cost.
