Abstract: An electronic device includes display layers such as liquid crystal display layers and a backlight unit that provides illumination for the display layers. The backlight unit includes light-emitting diodes that emit light into the edge of a light guide film. To minimize the inactive area of the display, the light-emitting diodes are tightly spaced to approximate a line light source instead of point light sources. Color and/or luminance compensation layers are incorporated at various locations within the backlight structures to ensure that the backlight provided to the display layers is homogenous. A thin-film transistor layer of the display is coupled to a printed circuit board by a flexible printed circuit. The flexible printed circuit has additional solder mask layers to improve robustness, encapsulation, and traces with a varying pitch.

Abstract: A transparent high-conductivity layer for providing electrostatic feedback to a user of an electronic device. The transparent high-conductivity layer is positioned over a capacitive input sensor and has a resistivity sufficiently high to prevent interference with the capacitive input sensor. As one example, the transparent high-conductivity layer can be formed from a layer of geometrically-separated regions of high-conductivity material. The average distance between geometrically-separated regions can substantially define the resistivity of the transparent high-conductivity layer.

Abstract: In devices with flexible displays, multilayer adhesive stacks may be included. A multilayer adhesive may attach a flexible display panel to the display cover layer in an electronic device. Including multiple layers of adhesive in the adhesive stack (as opposed to a single layer) provides more degrees of freedom for the tuning and optimization of the properties of the adhesive stack. The multilayer adhesive stack therefore has better performance than if only a single layer of adhesive is used. The multilayer adhesive stack may include one or more layers of soft adhesive, hard adhesive, hard elastomer, hard polymer, and/or glass to optimize the mechanical and optical performance of the multilayer adhesive stack. Soft adhesive layers may be included to optimize lateral decoupling (e.g., during folding and unfolding) of the adhesive stack. Harder layers may be included to provide rigidity and prevent denting during impact events.
