Abstract: A display device and a driving method thereof. The display device includes a display substrate and at least one optical sensing unit; the display substrate includes a light-emitting region and a plurality of pixel units located in the light-emitting region; wherein the light-emitting region comprises a single-sided light-emitting region and at least one double-sided light-emitting region, and each of the pixel units in the plurality of pixel units comprises a plurality of sub-pixels; and the at least one optical sensing unit corresponds to the at least one double-sided light-emitting region from a non-display side of the display substrate, and configured to sense light emitted by the sub-pixels during operation in the at least one double-sided light-emitting region, and to provide sensing brightness information of the at least one double-sided light-emitting region to perform brightness compensation on the light-emitting region.

Abstract: The present disclosure belongs to the technical field of microorganisms, and provides Streptomyces ardesiacus, a microbial biological control agent (MBCA) and use. The use specifically refers to prevention and treatment of various plant diseases. In the present disclosure, the Streptomyces ardesiacus has a serial number of HL-06, and has been deposited on Jun. 9, 2022, with a deposit number of CGMCC No. 25033. The HL-06 strain can degrade organic phosphorus and inorganic phosphorus, has a broad-spectrum antimicrobial activity, and can stimulate various defense enzymes of plants to improve disease resistance of the plants.
