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).
Abstract:
A scoreless separation device and method are described herein for separating a glass sheet without needing to score the glass sheet. In one embodiment, the device shears a stationary glass sheet without needing to score the glass sheet. In another embodiment, the device shears a moving glass sheet to remove outer edges from the moving glass sheet without needing to score the moving glass sheet.
Abstract:
A method of minimizing localized heating of, or minimizing signal losses across a source of loss in, an optical fiber used in transmission of a high power optical signal at an operating wavelength. These methods include the steps of: providing an optical fiber which comprises a coating characterized by either (i) an absorbance of less than about 4.5 dB/cm at the operating wavelength or (ii) a refractive index lower than the refractive index of a cladding layer of the optical fiber by more than about 3x10-3 at the operating wavelength, or (iii) both (i) and (ii); and transmitting a optical signal having a power greater than about 250 mW through the optical fiber, wherein the coating, cladding layer, or combination thereof are selected to minimize localized heating of the optical fiber or to result in a signal loss across a source of loss that is less than about 250 mW at the operating wavelength.
