Abstract: A dimensionless kinematics calibration method based on a virtual point and a related apparatus thereof. The method comprises: establishing a kinematics model of a motion mechanism, and arranging a plurality of virtual points at a tail end of the motion mechanism to establish a dimensionless kinematics model and a dimensionless error model; converting a measurement coordinate system into a motion mechanism coordinate system, acquiring a rotation matrix and a translation matrix of a target virtual point measured by the measurement device, and calculating actual coordinates of all virtual points to obtain a measured value of the dimensionless kinematics model; calculating a theoretical value of the dimensionless kinematics model according to a spatial relationship between a reflecting head and the tail end of the motion mechanism; and optimizing the dimensionless error model according to the measured value and the theoretical value to obtain a calibration result.

Abstract: A display module, a manufacturing method thereof, and an electronic terminal are provided. The display module includes a circuit board and a display panel electrically connected to each other. The display panel includes an array substrate and a color filter substrate disposed opposite to each other. The array substrate includes a first common electrode and a second common electrode, and the color filter substrate includes a third common electrode. A first gamma pin of a digital power management integrated chip disposed on the circuit board is electrically connected to the first common electrode, the second common electrode, or the third common electrode.

Abstract: A display device and a display method thereof are provided. An image compensation unit is utilized to analyze a first image signal and a second panel data to calculate a difference value between a row number of first virtual rows included in the first image signal and a row number of second virtual rows included in the second panel data. Further, the first image signal is compensated to obtain a third display signal to display on the display panel, which can improve a display abnormality problem that occurs when the display panel is matched with an image input module from different manufacturers.

Abstract: The present application provides a display panel and a brightness compensation method thereof. Multiple sub-pixel units in each pixel unit share the same sensing unit, and the normal display process and optical inspection process of each pixel unit are carried out separately, so as to make each sub-pixel unit reach the target brightness. As a result, the number of sensing units in the optical compensation system could be reduced; the manufacturing process of the display panel could be simplified, and the manufacturing cost of the display panel could be reduced.

Abstract: A vascular stent, including a plurality of wave-shaped supporters connected in an axial direction. The tubular stent includes a proximal support mechanism, a middle support mechanism, and a differential support mechanism connected in sequence; the middle support mechanism and the distal support mechanism are respectively closed-loop structure; the proximal support mechanism includes a first support portion connected to the middle support mechanism and a second support portion provided at the proximal end of the first support portion; the first support portion is a closed-loop structure; the second support portion is an open-loop structure, and the end surface of the proximal end of the second support portion is an uneven structure to provide local support in the circumferential direction.

Abstract: Text data transmitted by a user device to a first server is retrieved. The text data is processed to determine whether an information recommendation rule set includes an information recommendation rule matching the text data. The information recommendation rule is set based on a recommendation information. If the information recommendation rule set includes the information recommendation rule matching the text data, the recommendation information is retrieved from a second server. A recommendation based on the recommendation information is transmitted to the user device.
