Abstract
An organic light emitting diode array substrate and an electronic device. The organic light emitting diode array substrate includes a display region, and a first package test electrode and a first package test lead which are outside the display region. The display region includes a first power supply line and a first signal line; the first package test lead is configured to connect the first package test electrode with the first power supply line to provide a first supply voltage for the display region; the first signal line is configured to provide a first electrical signal for the display region; and a thermal conductivity of the first package test lead is higher than a thermal conductivity of the first signal line.
