Abstract

The present invention relates to a device for removing defective light emitting diodes. The device for removing defective light emitting diodes is used to remove defective light emitting diodes from a plurality of light emitting diodes arranged on a light emitting diode substrate. The device for removing defective light emitting diodes includes: a main stage for setting The above-mentioned light-emitting diode substrate; the laser irradiation part is used to irradiate laser light to the defective light-emitting diodes existing on the above-mentioned light-emitting diode substrate; A heated defective LED; and a connecting pipe connected between the laser irradiation part and the LED removal part, used to seal the space between the laser irradiation part and the LED removal part, and has flexibility.

Description

technical field [0001] The present invention relates to a defective light emitting diode removal device, and more specifically, to a defective light emitting diode removal device that can perform a defective light emitting diode removal process that must be included in a light emitting diode repair process. Background technique [0002] Light Emitting Diode (Light Emitting Diode) is composed of an N-type semiconductor with many electrons and a P-type semiconductor with many holes. If a forward voltage is applied to the semiconductor, the electrons and holes will move to regenerate at the junction. Combined, this recombined energy becomes light and is released. [0003] Light-emitting diodes have low power consumption, long life, high efficiency, extremely small size, instant lighting, wide operating temperature range, high impact resistance and vibration resistance, no ultraviolet and infrared rays, and no filter Under the circumstances, it embodies the inherent advantages ...
