Disclosed are a display panel and a sound box. The display panel includes a screen body, a cover plate, a protrusion portion, a first adhesive portion and a second adhesive portion. The first adhesive portion is filled between a region of the cover plate exposed from the protrusion portion and the screen body, and the second adhesive portion is filled between the protrusion portion and the screen body, such that no gap is generated between the cover plate and the screen body and between the protrusion portion and the screen body, so as to eliminate bubbles visible to human eyes after a defoaming treatment of the screen body and the cover plate, thereby improving a display effect of the display panel.

Disclosed are systems and devices including handholds that can be added to bath enclosures to improve safety of the user. The handhold can be securely attached to a shower surface or a bath surface. A handle is configured to provide the handhold by allowing a user to grasp thereto. A support substrate is coupled to the handle providing a rigid base. A first adhesive layer couples the support substrate to the shower surface or the bath surface and is configured to support the weight of the system upon mounting the system to the shower surface or the bath surface. A second adhesive layer couples the support substrate to the shower surface or the bath surface and is configured to support the weight of the system and a weight applied by the user after curing.
