Abstract

The invention provides a display panel and a display device, and the display panel comprises a photosensitive area, a substrate, a light-emitting layer, and a light blocking layer. A semiconductor layer is arranged on one side of the substrate and comprises a plurality of semiconductor elements, and the semiconductor elements comprise first semiconductor elements located in the photosensitive area. The light-emitting layer is located on the side, away from the substrate, of the semiconductor layer, the light blocking layer is located on the side, away from the light-emitting layer, of the semiconductor layer, the light blocking layer comprises a plurality of first light blocking parts arranged at intervals, and the first light blocking parts correspond to the first semiconductor elements. The orthographic projection of the first light blocking part on the plane where the substrate is located is at least partially overlapped with the orthographic projection of the first semiconductor element on the plane where the substrate is located. According to the display panel, the first light blocking part is arranged on the side, away from the light-emitting layer, of the first semiconductor element, the intensity of light irradiated to the first semiconductor element is effectively reduced, the display difference of the display panel is reduced, and the display effect of the display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] At present, when FOD (Finger on Dispaly) technology is applied to the display panel, it can not only realize the front touch display panel, but also realize the safe unlocking function of the display panel, which not only facilitates the operation of the user, but also The appearance of the display panel is improved, so it is widely used in display devices such as mobile phones and tablets. [0003] Usually, a photosensitive area is provided on the display panel, and a photosensitive element is arranged in the photosensitive area, and fingerprint recognition is performed through the photosensitive element to realize unlocking of the display device. After the screen is unlocked, the photosensitive area can perform normal touch operations. However, in the process of using display devices such as mobile ...
