摘要:
A display backplane is provided, including a base, wherein pixel circuits, bonding electrodes, and bonding connection wires are on the base; the bonding electrodes are coupled to the bonding connection wires in a one-to-one correspondence; the bonding electrodes and the bonding connection wires are on two opposite surfaces of the base; the pixel circuits and the bonding connection wires are on a same side of the base; one end of each bonding connection wire is coupled to the bonding electrode through the first via in the base; the other end of each of at least some bonding connection wires is coupled to the pixel circuit; and an orthographic projection of at least one of the bonding electrodes and the bonding connection wires on the base is not coincident with an orthographic projection of the pixel circuit on the base.
