Abstract: Methods provide for post processing at least one flexible glass sheet with the step of providing the glass sheet with an initial shape. The method then further includes the step of flexing the glass sheet into a secondary shape from the initial shape. The method then further includes the step of post processing the glass sheet while biasing the glass sheet into the secondary shape. The method then still further includes the step of releasing the glass sheet to at least partially return to the initial shape.

Abstract: A mold for shaping glass can be made by a method that includes providing a mold body having a shaping surface comprising at least about 90% nickel and modifying the composition of the shaping surface of the mold body by exposing the shaping surface to an oxidizing heat treatment. The oxidizing heat treatment may include a ramping heat treatment, a fixed heat treatment, or both the ramping heat treatment and the fixed heat treatment. The ramping heat treatment may include increasing a heating temperature at a rate from about 20° C./hour to about 500° C./hour to a temperature from about 700° C. to about 1000° C. The fixed heat treatment may include holding the heating temperature from about 700° C. to about 1000° C. for a holding time of at least about 5 minutes.

Abstract: A method for identifying an application scenario of a terminal device, where the method includes analyzing an application program running on a terminal device by means of compilation to obtain characteristic data of the application program; and determining, from a scenario characteristic data set according to the characteristic data of the application program, application scenario information corresponding to the characteristic data of the application program, where the scenario characteristic data set includes a correspondence between multiple types of application scenario information and characteristic data of multiple application programs. Because characteristic data of an application program is more likely to be unique in describing a corresponding application scenario, application scenario information corresponding to the characteristic data of the application program is relatively accurate.

Abstract: Methods and apparatus for convective heat treatment of thin glass sheets (17) are provided. The glass sheets (17) are held in a fixture (9) which has a processing volume (19) which has an open top and an open bottom. A bottom support system (15) supports the bottom edges of the glass sheets (17) without blocking a substantial portion of the processing volume's open bottom. A side support system (13) holds the vertical edge regions of the glass sheets during the convective heat treatment, thus reducing vibration and distortion (warp) of the sheets as a result of the heat treatment. The side support system (13) can include vertical members (33) having arms (37) that can include lips (73) for engaging the major surfaces of the glass sheets (17).

Abstract: A hermetically sealed device comprising a spacing unit and a resistive heating element desirably having a closed-loop structure and process for hermetically sealing a device by using such heating element and spacing unit. The frit can form multiple closed-loops to prevent crack propagation. The heating element can be advantageously made of a metal such as Invar® and/or Kovar®. The invention enables hermetic frit sealing with low residual stress in the seal for large-area displays. The invention is particularly advantageous for hermetic sealing of OLED display devices having a large area, such as those above 10 inches (25 cm).

Abstract: A mandrel 1 includes a top support 10, a first edge support 20, a bottom support 30, and a second edge support 40. The top support and first edge support make-up a first support section. The bottom support and second edge support make-up a second support section. The first support section and the second support section are disposed relative to one another so as to form an outer circumference. A jack 50 is coupled to the first and second support sections and is configured to move the first and second support sections relative to one another so as to adjust the outer circumference of the mandrel. A locking element 60 removably is coupled to the first and second support sections to selectively prevent relative movement between the first and second support sections.
