Abstract

The invention relates to an LED chip test fixture, a test method and a test system. The LED chip test fixture provides a substrate on which a test electrode is laid, an electrolyte layer on the substrate is attached to a chip film on which LED chips arranged in an array manner are laid, therefore, a positive test electrode and a negative test electrode are respectively aligned with the corresponding electrodes of the LED chip to be tested. The LED chip test fixture is advantaged in that an LED chip testing jig can be used for testing the photoelectric characteristics of a large number of LED chips, and the LED chip testing jig is convenient, simple and high in accuracy.

Description

technical field [0001] The invention belongs to the technical field of light emitting diode (English: Light Emitting Diode, LED for short) testing, and more specifically relates to an LED chip testing fixture, testing method and testing system. Background technique [0002] Miniaturized (English: Micro) LED chips can be used in direct view (English: Direct View) display technology to form a light-emitting unit, which has the advantages of high brightness, wide color gamut, high stability, long life, energy saving, and transparency. However, there are still many technical difficulties that need to be resolved before the mass production of miniaturized LED display technology, and the photoelectric characteristic test is one of the difficulties. [0003] On the one hand, the repair cost of miniaturized Micro LED chips used in direct-view display technology is very high, so it must have a high yield rate when placed on the target backplane in order to reduce the number of repair...
