Abstract: The present disclosure discloses a focusing control method, apparatus and system, and a storage medium, which relates to the field of control. The focusing control method includes: controlling a carrier platform carrying a display panel to move in a preset direction at a preset speed; controlling a distance measuring sensor to measure a first distance between the distance measuring sensor and a detection point, wherein the detection point is a point on a surface of the display panel located at a preset distance measuring position; adjusting a distance between an image acquiring device and the detection point based on the first distance in a case where the detection point reaches a preset image acquiring position in a field of view of the image acquiring device; and controlling the image acquiring device to acquire an image of the surface of the display panel.

Abstract: A method for detecting a display panel defect, including: collecting a panel image of a to-be-detected display panel, a plurality of first pixels of the display panel corresponding to a plurality of second pixels in the panel image; converting the panel image into a binary image; dilating each bright spot region in the binary image such that adjacent bright spot regions communicate with each other to form at least one closed communication region in the binary image; determining a region of interest mask image in the binary image in accordance with the at least one closed communication region; determining a region of interest in accordance with the region of interest mask image and the panel image; and performing feature identification on the region of interest to determine a defect of the display panel.

Abstract: Provided are a gRNA mutant and the use thereof, and further provided are a method for constructing same and a base editor containing same. The gRNA mutant is used in the base editor, and can universally reduce a base editing window, thereby improving the specificity of gene editing, and achieving specific editing on one base.

Abstract: Disclosed is a cranial decompression connector, including two screws (1) and an elastic connecting member (2) connected between the two screws (1). Two ends of the elastic connecting member (2) are respectively connected to the two screws (1), one screw (1) is configured to be fixedly connected to a bone window, and the other screw (1) is configured to be fixedly connected to a bone plate. When a patient undergoes a craniotomy, the two screws (1) are respectively fixed to the bone window and the bone plate, and the two ends of the elastic connecting member (2) are respectively connected to the two screws (1) to connect the bone window and the bone plate together.
