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: An integrated circuit includes a decoupling capacitor and an internal circuit. The decoupling capacitor is coupled to a first external terminal of the integrated circuit. The internal circuit in the integrated circuit is coupled to a second external terminal of the integrated circuit. The decoupling capacitor is coupled to provide supply voltage current to the internal circuit through the first and the second external terminals and through external conductors. The external conductors are outside the integrated circuit.

Abstract: Systems and methods are provided for reducing jitter due to power supply noise in an integrated circuit by drawing additional current. The additional current causes the total current to generally have a frequency higher than a resonant frequency of the integrated circuit and/or a power distribution network of the integrated circuit. In one example, a power distribution network may supply power to components of an integrated circuit and data driver circuitry may draw first current to drive a data signal. Compensation circuitry may draw second current at times when the data driver circuitry is not drawing the first current, thereby causing a net of the first and second current to be higher than a resonant frequency range of the integrated circuit device and/or a component of the integrated circuit device (e.g., the power distribution network).
