A hermetically sealed glass package and a method of making the hermetically sealed glass package are presented as preparation examples for use in OLED displays. According to one embodiment, the hermetically sealed glass package is produced by providing a first substrate plate and a second substrate plate. The second substrate comprises at least one transition metal or rare earth metal, such as iron, copper, vanadium, manganese, cobalt, nickel, chromium, neodymium and / or cerium. A sensitive thin film device requiring protection is deposited on the first substrate plate. A laser is used to heat the doped second substrate plate to some extent to swell a portion of it and form a seal to connect the first substrate plate and the second substrate plate and also to protect the thin device. The second substrate plate is doped with at least one transition metal to cause absorption of light from the laser in the second substrate plate when interacting with the laser, which creates a seal that avoids thermal damage to the thin film device. To form. Another embodiment of a hermetically sealed glass package and a method of making a hermetically sealed glass package are also described. |
