What is it about?
As the substrate materials of OLED display, its high strain point ( > 730degrees) and high elastic modulus ( > 80 GPa) suggests that the total amount of SiO2 and Al2O3 should be higher than that of the TFT-LCD glass substrate and any other alumino-silicate glasses, which will inevitably increase the viscosity of glass melt and bring more difficulties in the glass melting and clarification process. This paper foucused on the effects of Al2O3/SiO2 and B2O3/SiO2 substitution on the network structure and properties of this kind of high aluminium (11~14 mol%) and low boron (1~1.5 mol%) alkali-free aluminoborosilicate glasses with the glass system of (81.8-82.3) (SiO2+Al2O3)-(1-3)B2O3-16.5RO (wt.%) used as OLED display glass substrate.

Why is it important?
OLED display substrate glasses, its high thermal durabililty and high elastic modulus, enables it the ideal substrate material as OLED display.
