Abstract

The invention relates to an assembly-line LED (light emitting diode) display unit uniformity detection method, system and device. The method comprises the steps: (a) acquiring a serial number of an LED display unit flowing through a preset position of an assembly line; (b) acquiring multiple different color images of the corresponding LED display unit and obtaining brightness information of the multiple different color images; (c) processing and analyzing the brightness information to obtain a display uniformity index of the LED display unit, wherein the display uniformity index comprises one of a death lamp index, a brightness and chrominance dispersion index and overall brightness and chrominance index; (d) correlating and storing the serial number and the display uniformity index of the LED display unit. The display uniformity index is acquired by virtue of the assembly line way, so that the delivery quality of a product can be improved, reference information can be provided for the subsequent production, and the assembly-line LED display unit uniformity detection method also has characteristics that the manpower and material resource can be saved, the efficiency can be improved, the automation degree can be increased, and the like.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to a method for detecting the uniformity of a pipelined LED display unit, a system for detecting the uniformity of a pipelined LED display unit and a device for detecting uniformity. Background technique [0002] Since the 21st century, the color display industry has developed unprecedentedly, and LED display screens have spread all over the central squares and commercial buildings of various cities. LED display screens are well received by people for their unique advantages of bright colors, high visibility, and low power consumption. However, due to the low level of domestic LED display manufacturing technology, the produced LED lights themselves have relatively large brightness and chromaticity. Differences (for example, the brightness of the same production batch of LEDs may vary by nearly 50%, and the chromaticity may vary by 15-20nm), and the differences in brightness and chromat...
