Abstract: In an embodiment a splicing display positioning method includes obtaining a distance and/or a direction from a UWB base point device to a UWB label based on a UWB ranging technology and a UWB direction-finding technology, wherein a plurality of displays are spliced into a splicing display, wherein one UWB label is installed on each display, and wherein different displays are distinguished based on the UWB labels installed on the displays, calculating a mutual position relationship between the UWB labels based on the distance and/or the direction from the UWB base point device to each UWB label and determining a position of each display in the splicing display based on the mutual position relationship between the UWB labels.

Abstract: Provided in the present disclosure is a glass-plastic hybrid lens assembly. The glass-plastic hybrid lens assembly comprises a glass lens and at least one plastic lens from an object side to an image side of the glass-plastic hybrid lens assembly in turn; and an ultraviolet cutoff layer, in which the ultraviolet cutoff layer is disposed at a side of the plastic lens away from the image side, and the ultraviolet cutoff layer is disposed spaced from the plastic lens. The glass-plastic hybrid lens assembly is simple and easy to be realized; the ultraviolet cutoff layer can effectively absorb or reflect the ultraviolet irradiation on the glass-plastic hybrid lens assembly, thereby preventing subsequent plastic lenses from ultraviolet irradiation effectively and solving demoulding and yellowing phenomena of plastic lenses occurring under strong UV irradiation effectively, thus effectively improving the UV resistance and solar-irradiance resistance of the glass-plastic hybrid lens assembly.
