摘要： A light-emitting substrate includes a base, a first conductive pattern layer disposed on the base and a second conductive pattern layer disposed on a side of the first conductive pattern layer away from the base. The first conductive pattern layer includes first signal lines. The second conductive pattern layer includes lamp bead pads. The lamp bead pads include first lamp bead pads and at least one second lamp bead pad. A vertical projection of each first lamp bead pad on the base at least partially overlaps with a vertical projection of a first signal line on the base. A vertical projection of each second lamp bead pad on the base is outside vertical projections of the first signal lines on the base. A distance between a first lamp bead pad and the base is substantially the same as a distance between a second lamp bead pad and the base.

摘要： A voltage control circuit comprises a sampling sub-circuit and a control sub-circuit. The sampling sub-circuit is configured to detect a potential difference between an output voltage and an input voltage to obtain a first voltage and output the first voltage to the control sub-circuit. The control sub-circuit is configured to compare a magnitude of the first voltage with a first voltage threshold, if the first voltage is less than the first voltage threshold, output the input voltage as the output voltage, and, if the first voltage is greater than or equal to the first voltage threshold, superimpose and output the input voltage and a bootstrap voltage as the output voltage.
