METHOD AND DEVICE FOR TESTING LIGHT-EMITTING DIODE DIE

摘要

A method for testing an LED die includes the following steps: setting control parameters; driving the LED die to emit light by applying an electric current to the LED die under the control parameters; detecting the wavelength of the light emitted by the LED die; and determining whether the LED die meets the predetermined electro-optical properties, based upon the relationship between the control parameters and the wavelength.
