Abstract
A device and a method for detecting LEDs bonded to a display substrate are provided. The device includes a power supply assembly, a pressure fixture and a detector. The power supply assembly is used for providing electrical signals to the LEDs. The pressure fixture is used for applying a force to the power supply assembly, so that the power supply assembly directly contacts and electrically connects to at least one of the LEDs. The detector is on a side of the pressure fixture away from the power supply assembly and used for detecting whether each of the LEDs emits light according to a normal standard.
