Abstract: The present invention discloses a display including a display panel and a light redirecting film disposed on the viewing side of the display panel. The light redirecting film comprises a light redistribution layer, and a light guide layer disposed on the light redistribution layer. The light redistribution layer includes a plurality of strip-shaped micro prisms extending along a first direction and arranged at intervals and a plurality of diffraction gratings arranged at the bottom of the intervals between the adjacent strip-shaped micro prisms, wherein each of the strip-shaped micro prisms has at least one inclined light-guide surface, and the bottom of each interval has at least one set of diffraction gratings, and the light guide layer is in contact with the strip-shaped micro prisms and the diffraction gratings.

Abstract: A pump health analysis method and a pump health analysis device using the same are provided. A standard vibration curve of a standard pump is obtained. The standard vibration curve is converted from a time domain to a frequency domain to obtain a first frequency distribution curve. A sample vibration curve of a sample pump is obtained. The sample vibration curve is converted from the time domain to the frequency domain to obtain a second frequency distribution curve. The first frequency distribution curve is compared with the second frequency distribution curve by using a cosine similarity algorithm to obtain a health index of the sample pump.
