摘要： A display panel and a display device are provided. The display panel comprises an array substrate, a first electrode, a pixel defining block, an organic common layer, a second electrode, an adhesive layer, and a thin film encapsulation layer. The organic common layer corresponding to the pixel defining block is defined with a through hole, and the adhesive layer is filled, which realizes a strong adhesion between the second electrode and the pixel defining block, and reduces a risk of peeling between layers of the organic common layer.

摘要： A method of preparing a thermally activated delayed fluorescent material is disclosed. The method includes steps of adding a catalyst, an alkaline substance, and a solvent into a first reactant, i.e. a bromide of cyclopenta[def]fluorene-4,8-dione, and a second reactant, where a substitution reaction occurs so as to obtain a reaction solution, and removing an impurity from the reaction solution to obtain the thermally activated delayed fluorescent material, having a structural formula of:
. By using the cyclopenta[def]fluorene-4,8-dione as acceptor units, the triplet state energy level of the acceptor units is reduced, and the property of the intramolecular charge transfer state is enhanced, so that the light-emitting molecules are redshifted.-

摘要： A display module includes a display function layer, a display planar area, and a buffer layer. The display function layer is divided into a display segment, a compression segment, and a bending segment therebetween. The display planar area includes a compression overlapping area. A positive projection of the compression segment on the display segment covers the compression overlapping area. The buffer layer covers the compression overlapping area and is disposed on a side of the display function layer away from an eminent layer of the display function layer. The buffer layer comprises a metal layer. A protective layer is disposed on a side of the buffer layer away from the display function layer. The protective layer covers the compression overlapping area. A hardness of a material for the protective layer is greater than a hardness of a material for the metal layer.
