Abstract
A backplane and a glass-based circuit board. The backplane includes: a base substrate and a plurality of light-emitting units, arranged in an array on the base substrate. Each of the light-emitting units (110) includes at least one light-emitting sub-unit; the light-emitting sub-unit includes a connection line (200) and a plurality of light-emitting diode chips connected with the connection line, and the light-emitting diode chips are located on a side of the connection line away from the base substrate. The light-emitting diode chips (300) in the at least one light-emitting sub-unit are connected in series.
