Abstract: The present invention discloses a high-color gamut diffuser plate and a preparation method therefor, and relates to the field of diffuser plate material technologies. In the present invention, a high-haze diffusion layer, a quantum dot layer, and a specific-spectral absorption layer are formed through in-mold co-extrusion, to prepare a high-color gamut diffuser plate. Green perovskite in the quantum dot layer works in cooperation with a visible-light absorber in the specific-spectral absorption layer, to obtain an expected spectral emissivity profile, thereby enabling the high-color gamut diffuser plate to absorb a spectrum around 580 nm (yellow). Overlap between absorption spectra of an R/G (yellow) filter is reduced as much as possible, to avoid emission leakage in other colors. An increase in the color gamut is achieved through emission spectra similar to those of the QD.

Abstract: This disclosure describes an apparatus that enables rapid transitions during microwave-assisted magnetic recording (MAMR) of storage media. In various aspects, the apparatus incorporates a driver circuit configured to provide a controlled bias current through separate source and sink output terminals, which respond to feedback signals. An MAMR sensor connects between the source and sink output terminals and generates microwave fields when receiving the controlled bias current from the driver circuit. A common-mode feedback (CMFB) loop connects to the source and sink output terminals, detects common-mode voltage (CMV), and delivers feedback signals to the driver circuit to maintain CMV regulation of the MAMR sensor. A differential voltage regulation loop connects to the source and sink output terminals, providing feedback signals that maintain the MAMR sensor voltage differential at a reference value. The apparatus controls the magnetic recording process of the MAMR sensor with rapid transition times.
