Abstract:
An antimony-free glass suitable for use in a frit for producing a hermetically sealed glass package is described. The hermetically sealed glass package, such as an OLED display device, is manufactured by providing a first glass substrate plate and a second glass substrate plate and depositing the antimony-free frit onto the first substrate plate. OLEDs may be deposited on the second glass substrate plate. An irradiation source (e.g., laser, infrared light) is then used to heat the frit which melts and forms a hermetic seal that connects the first glass substrate plate to the second glass substrate plate and also protects the OLEDs. The antimony-free glass has excellent aqueous durability, good flow, low glass transition temperature and low coefficient of thermal expansion.

Abstract:
A hermetically sealed glass package and method for manufacturing the hermetically sealed glass package are described herein using an OLED display as an example. In one embodiment, the hermetically sealed glass package is manufactured by providing a first substrate plate and a second substrate plate. The second substrate contains at least one transition metal such as iron, copper, vanadium, manganese, cobalt, nickel, chromium, and/or neodymium. A sensitive thin-film device that needs protection is deposited onto the first substrate plate. A laser is then used to heat the doped second substrate plate in a manner that causes a portion of it to swell and form a hermetic seal that connects the first substrate plate to the second substrate plate and also protects the thin film device. The second substrate plate is doped with at least one transition metal such that when the laser interacts with it there is an absorption of light from the laser in the second substrate plate, which leads to the formation of the hermetic seal while avoiding thermal damage to the thin-film device. Another embodiment of the hermetically sealed glass package and a method for manufacturing that hermetically sealed glass package are also described herein.
Abstract:
A hermetically sealed glass package (100) and method (200) for manufacturing the hermetically sealed glass package (100) are described herein using an OLED display as an example. Basically, the hermetically sealed OLED display (100) is manufactured by providing (step 202) a first substrate plate (102) and a second substrate plate (107) and depositing (step 208) a frit (106) onto the second substrate plate (107). OLEDs (104) are deposited (step 206) on the first substrate plate (102). An irradiation source (110)(e.g., laser, infrared light) is then used to heat (step 212) the frit (106) which melts and forms a hermetic seal (108) that connects the first substrate plate (102) to the second substrate plate (107) and also protects the OLEDs (104). The frit (106) is glass that was doped with at least one transition metal and possibly a CTE lowering filler such that when the irradiation source (110) heats the frit, it softens and forms a bond. This enables the frit (106) to melt and form the hermetic seal (108) while avoiding thermal damage to the OLEDs (104).
