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 press-based fluidic transportation and diagnosis device includes a top plate, a first reagent storage chamber, a second reagent storage chamber, a sample inflow chamber, a detection chamber, a through hole and a gas outlet hole. On end of the second reagent storage chamber is communicated with the first reagent storage chamber by a first flow path. The sample inflow chamber is communicated with the other end of the second reagent storage chamber by a second flow path. On end of the detection chamber is communicated with the sample inflow chamber by a third flow path. The through hole is used for accommodating a press-based driving unit, and is communicated with the other end of the detection chamber by a fourth flow path. The gas outlet hole is communicated with the through hole by a fifth flow path.
