OLED analysis paper using LDI-TOF (SID publications by international information display societies)
LDI-TOF (Laser Desorption Ionization Time of Flight) is a mass spectrometry instrument used for OLED analysis and inspection, capable of direct analysis of OLED panels at the pixel level.
LDI-TOF has a built-in ultra-fine laser optical system, developed in-house, that can analyze spot sizes of less than 5㎛ and developed the world’s only equipment operating software based on the latest web technology (node.js) for convenience scalability.
ASTA succeeded in developing the world’s first next-generation LDI-TOP-based OLED analytical system.
