Abstract: The present invention provides a method for manufacturing a display panel, and the display panel. When the front-side process of the display panel is completed, a structure consisting of a protective layer, a sacrificial layer, a planarization layer, and a passivation layer is introduced as a protective film. The structure design of the protective film cannot cause pollution to a vacuum device such as CVD and PVD, and has hard abrasion resistance. The film cannot remain on a conveyor so as not to interfere with the back-side process. Moreover, when a conventional CVD and coating machine are used for film formation, the surface flatness of the film is conducive to transmission and adsorption. The protective film can be completely removed by means of laser and dry etching. The process method can effectively realize the double-sided process of single glass.

Abstract: A field wheat stem tillering number extraction method, comprising: acquiring field wheat point clouds by means of a laser radar, and extracting any row of wheat point clouds in a research area (S102); projecting a Y axis to a plane, and retaining an X axis and a Z axis (S103); applying adaptive layering to obtain the number of clusters of the row of wheat (S104); applying hierarchical clustering analysis to obtain the tillering number of each cluster of wheat (S105); and further obtaining the stem tillering number of the whole row of wheat (S106), so that a field wheat stem tillering number is extracted. The feasibility of an algorithm is verified by comparing the wheat stem tillering number extracted by means of the method with an actually measured field stem tillering number, and the method realizes rapid, accurate and nondestructive extraction of a large-field crop stem tillering number, has higher universality, and provides the theoretical basis and technical support for the extraction of the field wheat stem tillering number.
