    摘要: The coefficient of absorption of a pre-selected region of a glass sheet is preferentially increased. The glass sheet may thereafter be sealed to a substrate using a sealing laser. In one embodiment, the coefficient of absorption sheet is increased by irradiating the glass sheet at a wavelength of about 248 nm, preferably through a mask, to produce an irradiated pattern on the glass sheet having a pre-determined shape. The glass sheet is then heat treated, placed over a substrate and sealed to the substrate by exposing the irradiated pattern to a sealing laser light having a wavelength in the range between about 355 nm and 532 nm to produce a glass envelope. The method disclosed herein is useful, inter alia, for manufacturing electro-luminescent devices, such as light emitting diodes (LEDs) and in particular organic light emitting diodes (OLEDs).

    摘要: Methods are provided for laser patterning a partial depth surface portion of a glass body by controlling the amount of stress induced in the glass body. A laser beam is directed along an impinged path on the surface portion of the glass body to heat the glass body to form a swell. The glass body is then cooled and etched. The surface portion of the glass body is heated above the strain point at a heating rate HR to form a swell. The heating rate HR is a function of a target temperature T and an exposure time of the output laser beam. The exposure time is controlled to reach a target temperature above the softening point of the glass body and does not require a power density that would lead to laser ablation of the surface portion. The surface portion is cooled below the strain point to induce regions of localized stress. The unablated surface portion is etched while in a state of laser-induced localized stress to form a patterned glass body.
