Abstract
Aiming at the problem of controlling the thickness deviation of LTPS/OLED glass substrates,the influence mechanisms of the properties of molten glass,the structure of the overflow brick,the temperature field and the drawing process on the thickness uniformity in the overflow down-drawing method were studied.An integrated scheme for regulating melt properties,optimizing the structure of overflow bricks,precisely controlling the temperature field and strengthening tensile stability was proposed.The pilot test results show that the standard deviation of the optimized glass substrate thickness has decreased from 2.8 μm to 0.9 μm,with a maximum thickness deviation within±2.0 μm and a Process Capability Index(CPK)of 1.58.This provides a technical paradigm for the manufacturing of ultra-low thickness deviation display glass and promotes the autonomy of domestic high-end substrates.关键词
