Problems solved by technology

[0002] The organic light-emitting diode display panel (OLED) has the characteristics of self-luminescence and thinning. The display panel includes a first display area and a second display area. In the display panel, a light-shielding layer is formed on the side of the array substrate away from the light-emitting surface. The light-shielding layer is connected with the first display area. A light-transmitting part is formed at a position opposite to the display area, so that the light passes through the light-transmitting part to the photosensitive module arranged on the side of the display panel away from the light-emitting surface, but when the display panel displays, the first display corresponding to the light-transmitting part There will be a difference in display brightness between the second display area and the second display area without a light-transmitting part, which will affect the display effect of the display panel

Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel comprises a display function layer which comprises an array substrate and a light-emitting element layer formed on the array substrate; a shading layer is formed on the side, away from the light-emitting element layer, of the array substrate, and the shading layer is provided with a light-transmitting part in a first display area; a light regulation and control layer is formed on the side, away from the light emitting face of the display panel, of the display function layer, the orthographic projection of the light regulation and control layer on the shading layer covers the light-transmitting part, the light regulation and control layer comprises an electromagnetic switch assembly, and the electromagnetic switch assembly comprises a first polarity piece, a second polarity piece and an induction piece located between the first polarity piece and the second polarity piece; and the deflection amount of the induction piece is controlled through electromagnetic field flux generated between the first polarity piece and the second polarity piece, so that the induction piece is switched between a shading station and a light-transmitting station. The display panel is uniform in display brightness and good in user experience.
