Abstract:
Systems, methods, apparatus and products relate to drawing and blowing of ultra thin glass substrates, such as flexible display glass sheets, for example, organic light emitting diode (OLED) displays, liquid crystal displays (LCDs), and/or other flexible substrate applications, such as lighting, and/or other technologies, such as electro-wetting (EW), electro-phoretic display applications, etc. A localized heat source centripetally heats a vertical glass pre-form, while a pressurized air source blows the heated glass to expansion. An air bearing may centripetally blow air against the expanding pre-form to limit expansion and prevent contact of the pre-form with the localized heat source. Meanwhile, the pre-form is pulled vertically to draw the heated glass. The pre-form may float in a floatation mechanism to compensate for gravity when the pre-form is pulled upward. The blown and drawn pre-form may be cooled, coated with a polymer layer, and cut into a ribbon by in-line devices as it exits the air bearing. For example, a laser may helicoidally cut a polymer-coated blown and drawn pre-form into a ribbon, which may be rolled for collection.
