Abstract: A display panel and a display device. The display panel includes a substrate; a pixel definition layer provided on the substrate, the pixel definition layer including an isolation structure and a plurality of pixel openings formed and enclosed by the isolation structure; a support assembly arranged on a side of the isolation structure facing away from the substrate, the support assembly including two or more support columns located between two adjacent pixel openings; a cover plate located on a side of the support assembly facing away from the pixel definition layer. Between the two adjacent pixel openings, the support assembly includes two or more support columns, which can provide sufficient support to the cover plate, thereby effectively improving the problem of the cover plate being prone to deformation, and thus improving the impact of the deformation of the cover plate on the display effect.

Abstract: A mask, including a first clamping region and a second clamping region opposite to each other in a first direction, and at least one mask opening region disposed between the first clamping region and the second clamping region. The mask opening region is in a first initial shape before being tensioned. The mask opening region is in a first target shape during an evaporation deposition process. The first initial shape is different from the first target shape. The first initial shape includes a compensation pattern with respect to the first target shape. The compensation pattern includes a tensile deformation pattern and a thermal deformation pattern.

Abstract: A mask and a mask assembly. The mask includes an evaporation region and a peripheral region. The evaporation region includes at least one evaporation opening. The peripheral region includes a solid region arranged around the evaporation region. The solid region includes a stress-relieving portion. The stress-relieving portion is arranged around the evaporation region and is distributed in a circumferential direction.

Abstract: A display panel comprising a display region, a non-display region around the display region, and a transition display region located between the display region and the non-display region, wherein the display panel comprises: a display base plate; an encapsulation cover plate located on the display base plate and configured to seal the display base plate; a support column disposed between the display base plate and the encapsulation cover plate, and configured to support the encapsulation cover plate. In the transition display region, a surface of the encapsulation cover plate close to the display base plate is provided with a first groove, and/or a surface of the display base plate close to the encapsulation cover plate is provided with a second groove.

Abstract: A display panel and a display apparatus. The display panel includes a first display area including a light-transmitting display area. The display panel includes: a substrate; a pixel definition layer disposed on the substrate; a plurality of first spacers disposed on a side of the pixel definition layer facing away from the substrate, the first spacers being positioned in the first display area; a cover plate disposed on a side of the first spacers facing away from the substrate. The first display area includes at least two sub-areas sequentially arranged along a direction from center to edge. In one of the sub-areas on the substrate to an area of the one of sub-areas is different from another proportion of a total area of orthographic projections of first spacers in another one of the sub-areas to an area of the another one of the sub-areas.

Abstract: A group of anti-BCM single domain antibodies, as well as genes of the single domain antibodies in the group, a vector containing the single domain antibodies in the group, a chimeric antigen receptor, and a T cell modified by a chimeric antigen receptor, and detection and treatment application of the single domain antibodies in the group. The anti-BCMA single domain antibodies have high activity, high stability, high specificity, and high binding capability.

Abstract: A chimeric antigen receptor (CAR) may be include: a BCMA binding domain, a transmembrane domain, a co-stimulatory domain, and an intracellular signaling domain, wherein the BCMA binding domain includes heavy chain complementarity determining regions HCDR1-3, and the amino acid sequences of the HCDR1-3 are successively as shown in SEQ ID NO: 1-3.
