Display device

A structure holds a display panel arranged inside a cabinet from the both sides by means of a holding member and a frame portion, which are supported by the circumferential surface section, so as to reduce thickness and frame width without using a bezel and to ensure rigidity. The cabinet is provided with a frame portion positioned on the display surface side of the display panel, a circumferential surface portion positioned at the periphery of the display panel, and a rear surface portion covering the other surface side of the display panel. A protruding section is arranged on the outer circumference side of the periphery of the display panel and the holding member to extend from the display surface side of the display panel toward the side opposite to the display surface, on an inner surface of the frame portion. A reinforcing section is arranged for connecting the inner circumference section of the protruding section with the inner surface section of a frame portion. The protruding section is provided with connecting sections, which are integrally formed with the inner surface of the frame portion, annularly arranged on the outer circumference of the display panel, and integrally formed at a plurality of positions on the protruding section in the circumference direction. The holding member has a section to be connected with the connecting section.

The invention discloses a three-dimensional self-supported lithium-loving carrier-packaged metal lithium composite negative electrode and a preparation method thereof. The three-dimensional self-supported lithium-loving carrier-packaged metal lithium composite negative electrode comprises the following steps of 1) carbonizing melamine foam in an inertia atmosphere to obtain a nitrogen-rich lithium-loving three-dimensional self-supported carrier; and 2) packaging metal lithium in holes of the three-dimensional self-supported carrier to obtain the metal lithium composite negative electrode. Carbon sponge obtained by carbonization of melamine foam is used as a metal lithium carrier, and the metal lithium composite negative electrode has effects of guiding metal lithium to be uniformly deposited and preventing dendrite from being generated. Lithium-loving functional groups are uniformly arranged on the carrier, a lithium-loving coating layer is deposited on a hole surface of the carrier, the lithium-loving performance of the carrier is improved, the volume change of the metal lithium electrode during the circulation process is effectively buffered, moreover, the lithium-loving functional groups uniformly arranged on the three-dimensional carrier are used as active sites for metal lithium deposition, the nucleation over-potential is reduced, uniform nucleation of metal lithium can be effectively controlled, so that the dendrite generation is prevented.
