摘要： A light-emitting substrate comprises a plurality of signal channels arranged in sequence along a row direction. Each signal channel comprises a plurality of control areas arranged along a column direction, and each control area comprises at least one light area controlled by a same chip. In each signal channel, the light-emitting substrate is provided with a first driving line, a second driving line, and a plurality of reference power lines. The first driving line and the second driving line are respectively used for providing different driving signals to the chip. The reference power line is used for providing a reference power supply voltage to the chip. The reference power lines in a same signal channel are electrically connected, and at least one reference power line is provided between the first driving line and the second driving line.
