LG Display announced on the 27th that it has introduced its own developed 'artificial intelligence (AI) production system' for organic light-emitting diode (OLED) manufacturing processes.
The AI production system is a system in which AI collects and analyzes manufacturing data for the OLED process in real time, and LG Display has trained the AI with domain knowledge necessary for the OLED manufacturing process. By utilizing this, the company explains that it can automatically analyze numerous potential causes of defects in the OLED manufacturing process and derive solutions.
OLEDs are produced through more than 140 processes, during which tens of thousands of equipment data are added, requiring more sophisticated management. With the introduction of the AI production system, the time taken to analyze and improve the causes of quality defects has been greatly reduced from an average of 3 weeks to 2 days. Previously, engineers had to rely on their individual capabilities to solve problems under limited measurement conditions, but with the AI production system, the process for all products can be controlled immediately to meet the optimum quality conditions predicted by AI. Furthermore, real-time quality inspections can be conducted across all products, allowing for immediate identification of any defects.
Additionally, LG Display has established a system that automatically sends classified and analyzed data collected by AI to the responsible department via email every morning. If AI discovers an anomaly during the data analysis process, a process has been established to automatically hold the operation of the equipment causing the issue, ensuring both speed and safety. LG Display anticipates that the introduction of AI will result in over 200 billion won in annual expense reductions and improvements in employee productivity.
Meanwhile, LG Display noted that it is enhancing the speed of digital transformation (DX) across its operations based on AI. In June, it introduced generative AI and expanded its in-house knowledge search service with content covering overall company information, including safety, standards, human resources, and training materials. The large language model (LLM) is also continuously updated, evolving to the latest model from the LG Research Institute, 'Chat Exawone.' Additionally, it is promoting personal productivity enhancement in general office areas through the introduction of AI, such as collaboration tools and automatic email translation functions.
Lee Byung-seung, head of LG Display's DX Group, said, 'By actively incorporating DX into the development and manufacturing areas, we have maximized productivity and enhanced manufacturing competitiveness,' adding, 'Through DX, we will not only increase productivity in display development and production but also achieve industry-leading technology and efficiency in general operations.'
