Abstract: A display may have a pixel array such as a liquid crystal pixel array. The pixel array may be illuminated with backlight illumination from a direct-lit backlight unit. The backlight unit may include an array of light-emitting diodes (LEDs) on a printed circuit board. The display may have a notch to accommodate an input-output component. Reflective layers may be included in the notch. The backlight may include a color conversion layer with a property that varies as a function of position. The light-emitting diodes may be covered by a slab of encapsulant with recesses in an upper surface.

Abstract: Embodiments of the present disclosure relate generally to compositions and methods for the design of remote controlled biological systems, and more specifically to synthetic bioswitches that provide the ability to non-invasively and remotely control the function and activity of live cells, such as for example and not limitation, the expression of biologically active proteins or biological therapeutics, and the manipulation of physiologic or genetic processes and/or protein expression in live cells, in vivo (including, e.g., at desired anatomical sites) or ex vivo.
