Methods for bonding substrates using liquid adhesive
First Claim
1. A method for bonding substrates, comprising:
- applying liquid adhesive to at least one of the substrates;
applying ultraviolet light to an edge of the liquid adhesive using fiber-based equipment, wherein the fiber-based equipment includes a fiber bundle containing a strip of fibers, wherein applying the ultraviolet light comprises applying the ultraviolet light using the strip of fibers, wherein each fiber in the fiber bundle emits light, and wherein a light modulator is interposed within the path of each fiber; and
with a controller, sending control signals to the light modulator associated with each fiber to individually adjust a magnitude of light emitted by each fiber.

Abstract
Structures in an electronic device such as substrates associated with a display may be bonded together using liquid adhesive. Fiber-based equipment may be used to apply ultraviolet light to peripheral edges of an adhesive layer during bonding. There-dimensional adhesive shapes may be produced using nozzles with adjustable openings, computer-controlled positioners, and other adhesive dispensing equipment. Ultraviolet light may be applied to liquid adhesive through a mask with an opacity gradient. Adjustable shutter structures may control adhesive exposure to ultraviolet light. Ultraviolet light exposure may be used to create an adhesive dam that helps create a well defined adhesive border. Multiple layers of adhesive may be applied between a pair of substrates.

11. A method for bonding a display module to a display cover glass layer, comprising:
-
applying liquid adhesive between the display module and the display cover glass layer, wherein a housing structure is positioned adjacent to the display cover glass layer, and wherein there is a gap between the display module and the housing structure; and applying ultraviolet light to an edge of the liquid adhesive using fiber-based equipment, wherein the fiber-based equipment includes a fiber bundle containing a strip of side-firing fibers, and wherein applying the ultraviolet light to the edge of the liquid adhesive comprises inserting the fiber bundle into the gap and applying the ultraviolet light at a right angle relative to a longitudinal axis of the side-firing fibers. - View Dependent Claims (12, 13, 14, 15, 16, 17)
