Background
The Micro LED display technology is a display technology in which self-luminous LEDs with a micron level (less than 50 microns) are used as light-emitting pixel units and are assembled on a driving panel to form a high-density LED array. When the Micro LED is used for displaying, the number of chips reaches millions or even tens of millions, and in the production process, the defective points in the display chips need to be detected in time for removal or repair. For example, for a display screen of a 4K television, 4K × 2k × 3=24m Micro LED chips are required, the speed of conventional detection and sorting is 10K/hour, and the detection and sorting time of the Micro LED on a common 4-inch sheet can reach over 1000 hours, so that rapid and accurate detection of the Micro LED display chip is an urgent problem to be solved.
Raman scattering refers to the phenomenon that when laser with a certain frequency irradiates the surface of a sample, molecules in a substance absorb or release part of energy, vibrate in different modes and degrees, and then scatter light with different frequencies. The frequency variation is determined by the characteristics of the scattering material, and the mode of vibration of different atomic groups is unique, so that scattered light with specific frequency can be generated, and the scattered light carries information of the vibration of partial molecules in the sample. The composition, structure, vibration symmetry and size of the substance to be measured determine the change of frequency, so that the Raman spectrum can be used as an effective means for researching the structure of the substance.
