Display backplane and method for manufacturing the same, display panel and display device

A method for manufacturing a display backplane, comprising:

• forming a first backplane, comprising forming, on a first substrate, a first thin film transistor configured to drive a light emitting unit, the first substrate comprising a first substrate layer and a connecting member penetrating through the first substrate layer;
• forming a second backplane, comprising forming at least one second thin film transistor on a second substrate;
• and
• attaching the second backplane to a surface of the first substrate facing away from the first thin film transistor, wherein after the attaching, the at least one second thin film transistor is located between the second substrate and the first substrate,
• wherein one of a gate and a source of the first thin film transistor is connected to a drain of one of the at least one second thin film transistor via the connecting member.

A display backplane, comprising:

• a first backplane, comprising:
• a first substrate, the first substrate comprising a first substrate layer and a second connecting member penetrating through the first substrate layer, and
• a first thin film transistor, on the first substrate, configured to drive a light emitting unit;
• and
• a second backplane attached to a surface of the first substrate facing away from the first thin film transistor, comprising:
• a second substrate, and
• at least one second thin film transistor located between the second substrate and the first substrate,
• wherein a source of the first thin film transistor is connected to a drain of one of the at least one second thin film transistor via the second connecting member.
