Abstract
A display panel, a display device, and a pressure detecting method. The display panel includes: a first substrate, a plurality of light-emitting elements spaced with each other on one side of the first substrate, a plurality of photosensitive detecting elements, and elastic light-reflecting components arranged on a light-emitting side of the light-emitting elements, an orthographical projection of the photosensitive detecting elements on the first substrate is in an orthographical projection of the light-emitting elements on the first substrate; and the elastic light-reflecting components is configured to be deformed by pressing so that areas of orthographical projection thereof on the first substrate become larger to thereby change an amount of light emitted by the light-emitting elements, and reflected by the elastic light-reflecting components to the photosensitive detecting elements.
