Abstract
Disclosed are a display panel, a display substrate, and an inkjet printing method. The display panel includes an underlying substrate, anode layers of a plurality of organic light-emitting pixels arranged in a matrix over the underlying substrate; and reference lines and first switch transistors, arranged over the underlying substrate, each of the respective reference lines corresponds to each of the respective anode layers, and each of the first switch transistors corresponds to each of the anode layers; where each of the anode layers is connected with the corresponding reference line through the corresponding first switch transistor; and anode layers of the pixels in a same color share a same reference line, and anode layers of the pixels in different colors correspond to different reference lines; and the reference lines are configured to provide the anode layers with electric charges while organic light-emitting functional layers are being fabricated on the anode layers.
