Flat-panel monitor refers to that the ratio between length and complete machine thickness of display screen diagonal are more than 4：1 display device, including
Liquid crystal display, plasma scope, electroluminescent display and light emitting diode etc..In recent years, flat-panel monitor is in
Reveal slimming, lightweight and high-resolution development trend.Being thinned a problem can bringing is, the intensity of glass can be with
The reduction of thickness and decline, therefore the property of substrate glass is particularly important.In order to meet the requirement used, it is necessary to make to show
The glass shown still has higher intensity under small thickness.At present, in the composition of alumina silicate glass used, in order to protect
It is higher to demonstrate,prove factor, the alkali metal content such as ion-exchange capacity and meltbility, formability, devitrification resistance in view of glass baseplate.
, it is necessary to which glass baseplate to be maintained to 350 DEG C~450 DEG C for the treatment of temperature in the manufacturing process of flat-panel monitor
Under, at these temperatures, most of glass baseplates experienced to be handled by compression, so as to cause the change of heat endurance and size,
This is due to the irreversible change in size of glass baseplate caused by the fictive temperature of glass changes.The degree of compression depends on system
Make the process of glass and the viscoplasticity of glass.Because alkali-free glass has high strain-point, therefore there is good dimensional stability,
But due in raw material alkali metal be very difficult to remove completely.If alkali metal Li2O、Na2O and K2O total concentration is less than
About 0.1 mole of %), then it is assumed that these glass of the invention are substantially free of alkali metal.
