The embodiment of the invention relates to the technical field of display, and discloses a composite foam layer. The composite foam layer is used for laminating a panel with a bending area and a non-bending area, wherein the bending area is formed by bending the panel towards the direction of the surface for laminating the composite foam layer; in the direction perpendicular to the surface of thecomposite foam layer, the thickness of the part, located in the bending area, of the composite foam layer is smaller than that of the part, located in the non-bending area, of the composite foam layer. According to the composite foam layer and the display module provided by the embodiment of the invention, the lamination difficulty of the composite foam layer and the panel can be reduced by utilizing the composite foam layer, and the condition that the composite foam layer and the panel are not completely laminated is reduced.

The invention provides an assembly method of a curved display screen and the curved display screen, and solves the problem that the fitting difficulty in the process of assembling the conventional curved display screen is large. The assembly method of the curved display screen comprises the following steps: fitting a flexible display panel and flexible glass to form a whole body; mounting the whole body formed after fitting of the flexible display panel and the flexible glass into a border, wherein the border surrounds the periphery of the whole body formed after fitting of the flexible display panel and the flexible glass, and the perimeter of the border is smaller than that of the whole body formed after fitting of the organic light emitting diode panel and the flexible glass.

The invention discloses a special AB double-sided adhesive for a low-residue electronic screen. The special AB double-sided adhesive for the low-residue electronic screen is successively provided with a first release layer, a modified silicon layer, a PET substrate layer, an optical adhesive layer and a second release layer from top to bottom, wherein the modified silicon layer comprises the following components in parts by weight: polydimethylsiloxane 100 parts, amino silicone 8-10 parts, sodium methyl silicate 4-6 parts and epoxy resin 2-3 parts. Adhesive components of two sides of the AB double-sided adhesive are modified to improve automatic bubble discharge capacity of the silicon layer, so that after the double-sided adhesive are torn and adhered repeatedly, the bubble discharge capacity can still be excellent, and adhesion difficulty of the double-sided adhesive is reduced; and meanwhile, the light transmittance, the adhesion strength and the shock resistance of the optical adhesive layer are improved, and residual adhesive ratio is reduced. The AB double-sided adhesive is suitable for the field of electronic screens and the like.

The invention provides a liquid crystal box, a display device applying the liquid crystal box and a control method of the liquid crystal box and the display device. The liquid crystal box provided by the invention comprises a first transparent baseplate and a second transparent baseplate that are oppositely arranged, a liquid crystal layer arranged between the first transparent baseplate and the second transparent baseplate and transparent strip-shaped electrode layers relative to a touch control electrode layer, wherein the touch control electrode layer is formed on the first transparent baseplate; electrodes, for receiving the same control signal, of the touch control electrode layer are connected into a whole through connection parts; the transparent strip-shaped electrode layers are composed of a plurality of transparent strip-shaped electrodes formed on the second transparent baseplate; and each transparent strip-shaped electrode corresponds a lens area. The liquid crystal box provided by the invention can provide the touch control function and the switching function of the two-dimensional / three-dimensional display by only two layers of baseplates at the same time; and the light transmittance is higher during three-dimensional display.

The invention provides a propeller molding structure and belongs to the field of molding technology. The propeller molding structure comprises an integral lower mold, upper molds A of which the numberis the same as that of blades, and upper molds B of which the number is the same as that of the blades. The external suction surfaces of the upper molds A are positioned between the leading edge parting surfaces and the following edge parting surfaces of the upper molds A, and are positioned above the pressure surfaces of the lower molds after being matched; and the leading edge parting surfacesof the upper molds A are matched with the leading edge parting surface of the lower mold after being assembled, the following edge parting surfaces of the upper molds A are matched with the followingedge parting surface of the lower mold after being assembled, and the following edge side walls of the upper molds A are perpendicular to the following edge parting surfaces and are matched with the following edge side wall of the pressure surface of the lower mold after being assembled. Partial blade root suction surfaces starting from leading edges in the upper molds B are matched with adjacentpartial blade root suction surfaces starting from following edges after being assembled so as to form internal suction surfaces; and internal leading edge parting surfaces are matched with the leadingedge parting surfaces after being assembled. The propeller molding structure provided by the invention can reduce the modeling difficulty of overlapping areas of blade roots, increase the molding thickness of propeller blade roots, enhance the molding strength of blade roots, as well as reduce the mold assembly difficulty of propeller molding.

The invention discloses a display panel and a display device. The display panel includes a substrate, the substrate includes a binding area, and a bending area connected to the binding area; it also includes a supporting block corresponding to the bending area and the binding area, and the supporting block is arranged on the side of the substrate away from the display surface; The maximum thickness of the support block in the fixed area is greater than the maximum thickness of the support block located in the bending area. The solutions of the embodiments of the present invention reduce the risk of wire breakage in the bending area of ​​the display panel, thereby improving the yield rate of the display panel. At the same time, the supporting block located in the binding area partly replaces the raising block in the prior art, avoiding additional setting of the raising block, so there is no need for alignment during lamination, which reduces the difficulty of lamination.
