Abstract: The present disclosure discloses a method for strengthening a biological manganese oxidation using a magnetic field and use thereof. The method includes steps of inoculating a manganese-oxidizing microorganism into a culture medium containing Mn2+, performing magnetization treatment in a culture process, and then collecting a biogenic manganese oxide. The method includes steps of performing a primary magnetic field treatment at a magnetic field intensity of 0.2-50 mT for 1-5 h when culturing is performed for 6-12 h, continuing culturing after the primary magnetization treatment, and performing magnetization treatment once every other 24 h for culture time of 72 h. A magnetic field is applied to accelerate an oxidation rate of a manganese-oxidizing microorganism to Mn2+ and a biological manganese oxidation rate is respectively improved by 36.4% and 23.8% under an action of an alternating magnetic field or a constant magnetic field within 72 h.

Abstract: To reduce overall power consumption for an electronic display power management integrated circuit (PMIC), one of multiple electric power converters and/or electric power regulators may be selected based on an electrical load (e.g., due to the total brightness of the content displayed) on the electronic display at a given moment. In some embodiments, the PMIC may include a less efficient heavy load converter designed with high-current handling capability and a more efficient light load (e.g., low current) converter with lower current handling capability. A controller may dynamically select between the converters depending on a present load or an expected load on the electronic display.

Abstract: Systems, methods, and devices are provided for providing intra-frame luminance scaling to avoid drawing excessive power while still providing exceptional brightness. An instantaneous average pixel luminance of an electronic display may be determined. The instantaneous average pixel luminance may correspond to an amount of light currently being emitted by the electronic display due to a previous image frame and a current image frame. Based at least in part on the instantaneous average pixel luminance, the luminance of a subset of pixels of image data of the current image frame may be adjusted, thereby allowing the electronic display to operate at a relatively high brightness level without exceeding a power limit.

Abstract: A VCOM generator circuit generates a VCOM signal for an electronic display. The VCOM circuit includes an operational amplifier having reduced supply rails. In an implementation, the VCOM circuit has at least three supply rails, AVDD, ground or GND, and VP or VN, or both. VP is less than AVDD and greater than VN. VN is higher than ground and below VP. The VCOM circuit with reduced voltage supply rails for VP and VN reduces power consumption of the VCOM op amps. By reducing power consumption, this also reduces the surface temperature of the integrated circuit.
