Abstract: A system for measuring loading on a test specimen. The system includes the test specimen arranged between a first loading bar and a second loading bar. The system further includes a first loading unit and a second loading unit configured to apply a first load and a second load to the first and second loading bars, respectively. The system further includes a first clamp and a second clamp configured to hold the first and second loading bars against the first and second loads, respectively. The system further includes a clamp actuating unit configured to selectively release at least the first clamp. The clamp actuating unit further includes a controller configured to electrically actuate at least one first electromechanical transducer from a retained state to a released state to release the first clamp, such that the first loading bar applies a first loading wave to the test specimen.

Abstract: A display substrate and a driving method of the same, and a display device, relate to the technical field of displaying. The display substrate includes a plurality of island regions separated from each other, and hole regions located between adjacent island regions; wherein, each of the plurality of island regions comprises a plurality of subpixels, the plurality of subpixels include first subpixels, second subpixels and third subpixels; the first subpixels are located at four vertex positions of a virtual quadrilateral; the second subpixels and the third subpixels are located at positions of two center lines of the virtual quadrilateral, to separate adjacent first subpixels; each of the center lines is a connecting line between midpoints of a pair of opposite side edges of the virtual quadrilateral.
