Abstract

The invention discloses a display device, and belongs to the technical field of display. The display device can comprise a display panel, a flexible circuit board, a retaining wall, a supporting bottom plate and a supporting side plate. The flexible circuit board is provided with a photosensitive element, and excessive glue exists around the photosensitive element. In order to ensure that all parts in the display device are distributed compactly, one part of the retaining wall can be directly attached to the overflowing glue. A supporting side plate in the display device needs to be connected with one side, far away from a photosensitive element, of a retaining wall, and the supporting side plate is further connected with a flexible circuit board through a supporting bottom plate. Therefore, even if the retaining wall is attached to the overflowing glue around the photosensitive element, it can be guaranteed that the retaining wall is tightly connected with the flexible circuit board, the firmness of attachment between the retaining wall and the flexible circuit board is high, the probability that the retaining wall is separated from the flexible circuit board is effectively reduced, and then it can be guaranteed that the detection precision of the photosensitive element is high.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display device. Background technique [0002] With the advancement of technology, portable display devices such as smart watches or smart bracelets are increasingly popular. In order to enable the user to observe the display picture presented on the display device under different brightness environments, a photosensitive element for detecting the intensity of ambient light may be integrated in the display device. [0003] For example, the display device may include: a display panel, and a flexible circuit board located on the back of the display panel (that is, the side opposite to the display surface of the display panel), and the flexible circuit board may integrate photosensitive elements. In this way, the ambient light can pass through the display panel and then irradiate to the photosensitive element, so that the photosensitive element can sense the intensity o...
