Because LTPS lines use laser annealing to convert a-Si to LTPS, processing temperature is in the range of 500 ° C to 700 ° C. Low compaction glass is a necessary technology for the LTPS production line.
As display glass manufacturers are competing with each other to develop low-pressure real glass, expanded PPM for low-pressure solid glass is between 600 ° C and 650 ° C, with Corning and CPM dominating the Samsung LTPS production line.
IHS Markit said that in addition, Samsung actively invests in AMOLED LTPS production line, its production capacity is currently the highest panel makers.
On the other hand, Asahi Glass (AGC) dominates multiple panel makers. Pegasus successfully raised the yield of LTPS smart phone displays with AN Wizus. After that, almost 100% of China's LTPS panel makers applied ANWizus to the new LTPS production line.IHS said that Asahi Glass (AGC) and Corning currently account for the majority of LTPS market share.
IHS Markit said that since the AMOLED flexible display uses liquid crystal glass as a slide, the slide does not require two, but the performance requirements for the slide are still more stringent than LTPS LCD glass.
IHS Markit said that because the flexible AMOLED substrate is PI with a thickness of only 3 μm and the PI substrate is almost dependent on the properties of the slide, the performance specifications of the slide are more stringent than the LTPS LCD and the slide is difficult to be subjected to twice Use, AMOLED flexible panel still need a slide.
