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.
