Abstract: A battery electrode matching system includes one or more sensors configured to detect a first characteristic of a first electrode and a second characteristic of a second electrode, one or more signature applicators configured to mark the first electrode with a first signature and the second electrode with a second signature, and memory circuitry. The memory circuitry is configured to store a first profile corresponding to the first electrode, the first profile including first data indicative of the first characteristic and the first signature. The memory circuitry is also configured to store a second profile corresponding to the second electrode, the second profile including second data indicative of the second characteristic and the second signature.

Abstract: An electronic device may include a display having an array of pixels and a backlight that provides backlight illumination for the array of pixels. The backlight may be a direct-lit backlight with a two-dimensional array of light-emitting diodes operable in a local dimming scheme. The electronic device may include control circuitry that provides pixel signals to the array of pixels and backlight signals to the backlight. The control circuitry may adjust the pixel signals and the backlight signals to compensate for brightness and color non-uniformity in the backlight. To compensate for image-dependent backlight non-uniformity, the control circuitry may simulate artificial backlight data based on the target image to be displayed and stored point spread information. To compensate for white-point-dependent backlight non-uniformity, the control circuitry may use measured actual backlight data that describes color variations across the backlight for a given target white point.
