Abstract: Disclosed is a method for preparing the anti-sintering calcium-based energy storage material by vacuum freeze-drying, which includes preparation of a precursor solution by mixing a calcium salt and a metal salt of manganese, magnesium, iron, cobalt, aluminum, zirconium, titanium, chromium, nickel, lanthanum, yttrium, molybdenum, or other metals in deionized water, vacuum freeze-drying of the precursor solution to obtain fluffy powder, and calcination of the powder in an air atmosphere to obtain the anti-sintering calcium-based energy storage material. The preparation method of the present invention does not require special equipment and harsh conditions, and has strong operability. The prepared calcium-based energy storage materials feature strong stability, high energy storage capacity, etc., and can be used in industrial production.

Abstract: The present disclosure provides a display panel, and belongs to the technical field of display. The display panel in the present application includes a base substrate and a plurality of pixel units on the base substrate. Each of the pixel units includes a plurality of light-emitting units emitting light in different colors. Each of the the plurality of light-emitting unit includes a first electrode, an organic functional layer and a second electrode stacked sequentially along a direction away from the base substrate. Among the plurality of light-emitting units emitting light in different colors in each pixel unit, the second electrode of the light-emitting unit emitting light with a shortest wavelength has a smallest thickness along a direction perpendicular to the base substrate.

Abstract: A mask is provided that includes a first graphic region and a second graphic region disposed along a first direction. The first graphic region comprises a first splicing exposure region. The second graphic region comprises a second splicing exposure region. The first splicing exposure region is used for, after being translated along a first vector, forming a first splicing auxiliary region, and the first splicing auxiliary region coincides with the second splicing exposure region.

Abstract: A display panel, a display device and a method of controlling a display panel are provided. The display panel includes a base substrate, a plurality of sub-pixels, a plurality of gate lines each gate line being connected to at least one row of sub-pixels, a plurality of shift registers, and a plurality of auxiliary circuits located in a peripheral region of the base substrate.
