Abstract: A display apparatus, including: a display panel; a supporting layer, provided on a backlight side of the display panel; a circuit board, provided on a side of the supporting layer away from the display panel; and a shielding layer, overlaid on a side of the circuit board away from the display panel and including a first insulation layer and a conductive layer. The conductive layer includes a shielding portion and a leading-out portion; the first insulation layer exposes at least partial region of the leading-out portion; an orthographic projection of the shielding portion on the display panel is located within an orthographic projection of the circuit board on the display panel; an orthographic projection of the leading-out portion on the display panel is located outside the orthographic projection of the circuit board on the display panel; the leading-out portion is electrically connected to the supporting layer.

Abstract: A display module includes a flexible display panel including a display portion, a binding portion, and a bending portion; a first back film, a second back film fitted to the display portion and the binding portion, respectively, an auxiliary support layer located between the first and second back films, bonded with the back films through first and second adhesive layers, respectively, and provided with an elastic modulus greater than the first and second back films; orthographic projections of the back films are located in or overlaps with those of the display portion and the bind portion, respectively. Side edges of the first and second back films and the auxiliary support layer close to the bending portion are first, second and third side edges, respectively; a spacing between the third and first side edges and a spacing between the third and second side edges are 0-0.35 mm.

Abstract: The present disclosure discloses a self-curing fluid solidified soil composite curing agent and its application, which is composed of the following raw materials by mass percentage: 30-35% of cement, 10-20% of slag, 10-20% of gypsum, 5-8% of calcium carbide slag, 30-39% of microbial curing agent, 1-5% of self-curing microbeads. The present disclosure can effectively improve the compressive strength of the fluid solidified soil while ensuring the early fluidity of the fluid solidified soil, inhibit the shrinkage deformation of the fluid solidified soil, and improve the durability of the fluid solidified soil. The present disclosure improves the recycling rate of solid waste resources and has the characteristics of low cost and remarkable environmental protection effect under the premise of ensuring the application effect, which is suitable for large-scale promotion and application.
