1. A display drive system, comprising: a plurality of drive units and a control unit; wherein
the plurality of drive units are connected to a lamp panel, and at least one of the plurality of drive units is configured to drive, during a display stage, the lamp panel to emit light; and
the control unit is connected to the plurality of drive units, and is configured to detect an operating state of the drive units driving the lamp panel to emit light;
wherein in response to detecting that a first drive unit is abnormal, the lamp panel is driven, by a second drive unit, to emit light, wherein the first drive unit is at least one of the drive units driving the lamp panel to emit light, and the second drive unit is at least one of the plurality of drive units other than the first drive unit; and
the lamp panel comprises a light-emitting unit array formed by a plurality of light-emitting units arranged in arrays, the light-emitting unit array comprising a plurality of light-emitting unit sub-arrays; and a plurality of drive integrated circuits (IC) comprised in each of the drive units are organized into a plurality of drive IC groups, each of the drive IC groups comprising a plurality of drive ICs connected in series and arranged along a first direction, and the drive IC groups of the plurality of drive units being alternatingly arranged in a second direction;
wherein each of the light-emitting unit sub-arrays is connected to two of the drive ICs that respectively belong to different drive units, and the two of the drive ICs are arranged adjacently and alternatingly arranged in the second direction.
