Abstract: An electronic device may include a display panel. When content of an image frame is expected to consume relatively higher amounts of power, a controller of the electronic device may operate a switch to change a power supply of the display panel to be a power management integrated circuit of the electronic device. However, when content of an image frame is expected to consume relatively less amounts of power, the controller may operate the switch to change the power supply of the display panel to be a power supply of an electronic display, such as a power supply used to power driver circuitry of the electronic display.

Abstract: Methods for making gypsum wallboard and for enhancing the compressive strength of wallboard by the addition of polymeric oxyalkylate viscosity modifiers are described. Preferred compounds are a copolymer comprising blocks of ethylene oxide and propylene oxide ether-linked to (1,2 ethandiyl dintrilo) tetrakis (propanol), an ethylene oxide/propylene oxide block copolymer and a polyethylene glycol polymer cross-linked with bisphenol A diglycidyl ether and combinations thereof.
