With the expansion of the scale of this industry,the need for standardization of light-emitting diodes is becoming more and more urgent.Firstly,the standard formulation and standard system framework of domestic light-emitting diode displays were studied,and then based on SJ/T 11281-2017"Light-emitting Diodes(LED)Display Test Method"as an example,the test method and related test parameters of the light-emitting diode display are analyzed in detail through the mechanical,optical and electrical properties,and introduced the research related to testing methods in recent years.Finally,it is concluded that the formulation and improvement of industry standards are of great significance to the development of the entire LED display industry.
