Abstract:
A substrate with a textured surface is disclosed. The substrate may be, for example, a light emitter comprising a light guide, for example a backlight element for use in a display device, wherein a surface of the light guide, for example a glass substrate, is configured to have a textured surface with a predetermined RMS roughness and a predetermined correlation length of the texture. A plurality of light scatter supressing features can be provided on the textured surface. Textured surfaces disclosed herein may be effective to reduce electrostatic charging of the substrate surface. Methods of producing the textured surface are also disclosed.
Abstract:
Methods of producing a glass sheet each comprise the step of creating a vacuum to force the entire lateral portion of the glass ribbon to engage an anvil portion of a breaking device in the elastic zone. The vacuum is provided by a plurality of pressure zones that are operated independent from one another, wherein each pressure zone is provided with a set of suction cups. In further examples, glass ribbon breaking devices each include a plurality of pressure zones that are configured to be operated independent from one another with each pressure zone being provided with set of suction cups.
