Abstract

The invention discloses a light emitting diode (LED) module-based random matrix lamp mixing method and a system device thereof. The device comprises an artificial intelligence (AI) inserter. The method comprises the following steps of: constructing a software module for generating a random matrix, an AI inserter control end software module and an AI inserter functional module in an AI inserter control end PC according to LED module pixels; after real-time start, generating the random matrix according to the batch and the number of LED lamps; calling the random matrix and building a corresponding relationship between the feeding station number and the LED module pixels by the AI inserter control end software module; building a corresponding relationship between the LED batch and the feeding station number by the AI inserter functional module; and controlling the AI inserter to take out each LED lamp from the corresponding feeding station by the AI inserter control end software module, and inserting the LED lamps into corresponding positions of the modules to realize lamp mixing. By adopting computer programming for generating the random matrix, the risk of regular patterns of LED modules is reduced; and the same random matrix is adopted in each LED module, so the LED batch and the pixel positions of LEDs on the LED modules are fixed, the traceability of the LED lamps is realized, and the production risk is effectively controlled.

Description

technical field

[0001] The invention relates to the production and assembly technology of basic components of LED display screens, in particular to a random matrix mixing lamp method based on LED modules and a system device thereof. Background technique

[0002] The LED display screen is made up of tens of thousands of LED single lamps. The consistency of the brightness, chromaticity and viewing angle of the entire screen depends largely on the distribution of the LED single lamps used. Usually, LED manufacturers with mature technology will "mix lights" on all single lights before leaving the factory, so that a certain amount of LED lights can be randomly intercepted, and their performance parameters are basically the same, so as to ensure the brightness of the entire LED display screen. consistency.

[0003] However, in practice, many LED manufacturers do not have the conditions to mix lights, or technical limitations lead to insufficient mixing of lights, resulting in inc...
