Abstract
The present invention provides a display panel and a display device. The display panel includes: a flexible circuit board, a touch layer, a cover plate, and an auxiliary transparent layer arranged close to the cover plate; the flexible circuit board is connected to the touch layer, and the touch layer and the flexible circuit board are connected The position of the first sealant is provided, and the first sealant is located on the side of the flexible circuit board facing the cover; the distance between the surface of the auxiliary transparent layer facing the cover and the cover is not greater than the surface of the first sealant facing the cover The distance from the cover plate; when installing the cover plate, the cover plate is first in contact with the auxiliary transparent layer, which can avoid cracks between the first sealant, the touch layer and the flexible circuit board caused by the stress on the first sealant.
Description
technical field [0001] The present invention relates to the technical field of display devices, in particular to a display panel and a display device. Background technique [0002] With the gradual development of display device technology, flexible display panels have been gradually applied to wearable devices, such as smart watches and wrist phones. [0003] In the prior art, the display panel includes a flexible circuit board, a cover plate stacked in sequence, a polarizer, a touch layer, and a display layer; one end of the flexible circuit board is connected to the control device, and the other end of the flexible circuit board is connected to the touch layer. To realize the touch control of the display device. When it is produced, the display layer, touch layer and polarizer are first formed, and then the flexible circuit board is connected to the touch layer; in order to avoid the contact between the outside air and the touch layer, a solid sealant is often attached at...
