Abstract: A Demura compensating method and system, and a micro display device are provided according to the present disclosure. The method comprises: acquiring an initial display image displayed by pixels of a micro display panel; determining an actual brightness-gray relationship of each pixel from the initial display image; determining an actual gray-level value offset of each pixel based on the actual brightness-gray relationship of each pixel and a preset brightness-gray relationship; and, performing brightness compensation on each pixel to form improved display image data based on the actual gray-level value offset of each pixel. Since the gray level offset is determined for each pixel, compensating accurate and evenness of the display image are improved.

Abstract: A display substrate has an active area and a frame region located at at least one side of the active area.

Abstract: A bogie of a rail vehicle includes a frame, which includes two box-shaped longitudinal beam main bodies and a transverse beam main body; a wheelset, which includes an axle box, an axle and wheels mounted at two ends of the axle; a drive system, which at least includes a gearbox and a drive motor. Practice has proved that the two axle boxes arranged on the inner sides of the two longitudinal beam main bodies can reduce a volume by about 10%, and reduce a weight by about 10% to 15%, which can further reduce air resistance, and realize energy saving and emission reduction. The longitudinal beam main body is located on an inner side of a wheel, a span of the two the longitudinal beam main bodies is reduced, and the torsional rigidity of the frame is reduced, which is beneficial to improving a curve passing capacity.
