Abstract: An example circuit includes a substrate having a surface and electrically conductive lines. The electrically conductive lines extend in a direction substantially parallel to the surface and substantially orthogonal to a virtual centerline. The circuit also includes first and second instances of a driver device having respective first and second sides, and respective line outputs. The line outputs are arranged along the first side of the respective instance of the driver device, and the respective first side of each of the first and second instances of the driver device are nearer the virtual centerline than the second side thereof. The line outputs of the first instance of the driver device are coupled to a first set of the electrically conductive lines, and the line outputs of the second instance of the driver device are coupled to a second set of the electrically conductive lines.

Abstract: A light-emitting diode (LED) display driver is operable to drive LEDs of an LED display and has a display interval with sub-periods and a blank time, each sub-period having multiple segments. The LED display driver includes: a data input; LED channel outputs adapted to be coupled to LEDs to drive the LEDs; and blank time distribution circuitry coupled between the data input and the LED channel outputs. The blank time distribution circuitry operable to distribute the blank time as blank time portions added to at least some of the sub-periods. Each blank time portion is smaller than a duration of each sub-period.
