Abstract: Configurable amplifier systems are described in which the power supply rail of a linear amplifier, e.g., a class A amplifier, is modulated by a switching amplifier, e.g., a class D amplifier, that may also be configured to operate independently of the linear amplifier. Techniques are also described by which the standing current of the output stage of a linear amplifier is modulated based on the input signal to the linear amplifier or based on modulation of the power supply rail of the linear amplifier.

Abstract: A display system comprising a set of light sources that emit a set of frequencies that are capable of exciting a set of quantum dots is disclosed. The display system further comprises a controller that receives input image data to be rendered by the display system and sends out control signals to various components. In one embodiment, the display system may further comprise one, two or more modulators that illuminate the set of quantum dots to form a final rendered image. In one embodiment, the set of light sources optionally comprise a light of substantially uniform polarization—e.g., laser light sources—and may be modulated according to control signal from said controller. Other optional components may comprise a starting polarizer, a mid-polarizer, a first laser light filter, a finishing polarizer and a final laser light filter/reflector.
