Abstract: A a plant composite corrosion inhibitor for an oil field and a preparation method thereof belong to the technical field of preparation of oil field chemical agents. The plant composite corrosion inhibitor comprises a first plant ingredient, a second plant ingredient, a corrosion inhibition synergist and an organic solvent. The first plant ingredient is zeaxanthin and a derivative thereof obtained by supercritical CO2 extraction of marigold; the second plant ingredient is prepared from luffa leaves, guava leaves and eclipta according to a mass ratio of 5:8:9; the corrosion inhibition synergist is prepared by mixing potassium iodide, 8-hydroxyquinoline and sodium dodecyl benzene sulfonate according to a mass ratio of 3:4:2; and the organic solvent is ethanol with a mass concentration of 82%. The composite corrosion inhibitor has a good corrosion inhibition effect, and reduces harmful chemical ingredients in the corrosion inhibitor.

Abstract: The application discloses a backlight module and a display device, and the backlight module includes a light guiding plate, and a light deflector arranged on the side of a light exit face of the light guiding plate, where the light deflector includes a prism module; and the light deflector includes a plurality of light deflecting elements having a same structure, where the respective light deflecting elements are asymmetrically structured inclined from the normal perpendicular to the light exit face of the light guiding plate so that an angle of view of light exiting from the backlight module is deflected from the normal. The prism module includes at least one layer of prism sheet, and there are a plurality of strip-shaped convex prisms arranged in parallel on the surface of the prism sheet away from the light guiding plate.

Abstract: The present invention relates to the technical field of display, and discloses a light guide plate, a backlight source and a display apparatus, for solving the problem of the exit light non-uniformity of the backlight source.

Abstract: The present disclosure provides a backlight module and a display apparatus. The backlight module includes: a substrate configured to fix a plurality of light sources; the plurality of light sources fixed on the substrate and connected electrically to each other; and a light guide plate having at least one side on which a recess portion for receiving the plurality of light sources or receiving the plurality of light sources and at least part of the substrate is provided. At least the plurality of light sources are embedded into the recess portion, thus, the light emitted from the plurality of light sources may enter the light guide plate completely for utilization. Not only the brightness of the backlight module may be improved, but also the energy waste due to the part of the light of the plurality of light sources failing to enter the light guide plate may be avoided.
