    摘要： A display screen and a display device are provided. The display screen includes a display panel assembly, a light bar, and a reflective layer. The display panel assembly includes at least two display panels with a splicing gap between each two display panels. The light bar is attached to a display surface of the display panel assembly, covers the splicing gap, and has two opposite side surfaces extending along a length of the splicing gap. At least one side surface of the light bar is provided with the reflective layer to prevent black borders from appearing on the side surfaces of the light bar.

    摘要： The present application relates to the technical field of variable emissivity electrochromic structures, in particular to a variable emissivity electrochromic structure. Embodiments of the present application provide an variable emissivity electrochromic structure, which sequentially comprises a reflecting layer, an insulating layer and an adjusting layer along the thickness direction, wherein the reflecting layer is used for reflecting infrared light, the preparation material of the reflecting layer comprises a conductor or a semiconductor; the preparation material of the adjusting layer comprises a conductor or a semiconductor with infrared semitransparent property; the reflecting layer and the adjusting layer are respectively connected to two electrodes of a power supply, and the voltage can be adjusted; an optical resonant cavity structure is formed between the adjusting layer and the reflecting layer, and the optical resonant cavity is used for adjusting and controlling the absorption of infrared light; the infrared transmittance and absorption of the adjusting layer can be altered by adjusting the voltage of the power supply, so as to adjust the amount of infrared light entering the optical resonant cavity structure, and further adjust the infrared emissivity of the variable emissivity electrochromic structure. The embodiments of the present application provide a variable emissivity electrochromic structure, which can provide a structure with an adjustable IR emissivity. In addition, the novel variable emissivity electrochromic structure of the present application has the following advantages: a) low solar absorption; b) visible transparent; c) decoupling of the dynamic regulation of IR emissivity and visible color; d) controllable IR emissivity in initial state.
