Abstract: A display characterization system may be used to gather display flatness data and light leakage data from a display. The display characterization system may include a camera system that includes flatness measurement cameras and a light leakage measurement camera. The camera system may include a light guide plate covered with a patterned opaque layer or other planar light-emitting structures for emitting patterned light that is reflected from the display. A controller may use the light leakage measurement camera to capture light leakage data while a display backlight unit is on, a reference light source is on, and the planar light-emitting structures are not emitting light. The controller may use the flatness measurement cameras to capture flatness data while the backlight unit is off, the reference light source is off, and the light-emitting structures are reflecting light from the display.

Abstract: A display such as a liquid crystal display has a display substrate that includes a layer of liquid crystal material sandwiched between a color filter layer and a thin-film-transistor layer. An oversized polarizer is laminated to the surface of the display substrate. Laser-based polarizer trimming equipment is used to trim away excess portions of the polarizer from the display substrate. A thickness gauge gathers thickness information from the laminated polarizer and display substrate. The thickness information is used to adjust the position of a laser relative to the polarizer during polarizer trimming operations. The laser beam moves along a cutting path that is unique to the display substrate. A vision system performs an inspection to determine whether the display substrate is damaged following polarizer trimming operations. Based on the inspection, laser parameters may be adjusted prior to performing polarizer trimming operations on additional polarizers and display substrates.

Abstract: An electronic device is provided with a display such as a liquid crystal display. The display has a layer of liquid crystal material sandwiched between an upper display layer such as a color filter layer and a lower display layer such as a thin-film-transistor layer. An upper polarizer is formed on the upper surface of the color filter layer. A lower polarizer is formed on the lower surface of the thin-film-transistor layer. To protect display layers such as the color filter layer and the thin-film-transistor layer, a coating is deposited on a peripheral edge of the display layer. A laser is used to cut through portions of the polarizer that overhang the display layer while also cutting through the coating on the peripheral edge of the display layer. Following laser trimming operations, the coating is flush with an edge surface of the polarizer.

Abstract: An electronic device is provided with a display such as a liquid crystal display mounted in an electronic device housing. The display has a layer of liquid crystal material sandwiched between an upper display layer such as a color filter layer and a lower display layer such as a thin-film-transistor layer. An upper polarizer is formed on the upper surface of the color filter layer. A lower polarizer is formed on the lower surface of the thin-film-transistor layer. To protect display layers such as a glass color filter layer substrate for the color filter layer from damage during polarizer trimming operations, a coating is deposited on a peripheral edge of the glass color filter layer substrate. The coating may be formed from an elastomeric polymer such as silicone and may remain in place or may be removed following trimming operations.

Abstract: A two dimensional touch sensor panel can be thermoformed or curved by another process to a three-dimensional touch sensor panel, and the three-dimensional touch sensor panel can be laminated to a three-dimension surface having a highly curved or spherical shape. In some examples, thermoforming a two-dimensional touch sensor panel into a three-dimensional touch sensor panel can result in strain of the touch electrodes, and can result in non-uniform three-dimensional touch electrodes (distortion of the two-dimensional touch electrode pattern). The strain can be a function of the curved touch-sensitive surface and/or process related mechanical strain from thermoforming. In some examples, a three-dimensional touch sensor panel can be formed with uniform area touch electrodes using a two-dimensional touch sensor panel pattern with non-uniform area touch electrodes in accordance with the strain pattern expected for a given curved surface and thermoforming technique.

Abstract: An electronic device has sensors. More particularly, the electronic device is a small form factor electronic device such as earbuds, styluses, or electronic pencils, earphones, and so on. In some implementations, one or more touch sensors and one or more force sensors are coupled to a flexible circuit. In various implementations, the touch sensor and the force sensor are part of a single module controlled by a single controller. In a number of implementations, the flexible circuit is laminated to one or more portions of an interior surface of the electronic device.

Abstract: An electronic device may have a display, a display cover layer, and a drawn sheet-packed coherent fiber bundle. The coherent fiber bundle may have an input surface that receives an image from the display and a corresponding output surface to which the image is transported. The coherent fiber bundle may be placed between the display and the display cover layer and mounted to a housing. The coherent fiber bundle may have fiber cores with bends that help conceal the housing from view and make the display appear borderless. The coherent fiber bundle has filaments formed from elongated strands of binder in which multiple fibers are embedded. Sheets of filaments are stacked and fused together to form a block of material that is subsequently drawn to form the drawn sheet-packed coherent fiber bundle.

Abstract: A force input sensor includes a load cell to adapt a compressive force applied to the force input sensor into a strain experienced by a strain sensor in the load cell. In particular, the load cell includes two compression plates separated from one another by a gap so as to define a volume between them. A flexible substrate (a “diaphragm”)—includes a strain sensor and is disposed and supported within the volume. One of the two compression plates includes a feature (a “loading feature”) that extends toward a central region of the flexible substrate. As a result of this construction, when the compression plates receive a compressive force, the loading feature induces a bending moment in the flexible substrate, thereby straining the strain sensor.

Abstract: An electronic device may have a housing with a display. A protective display cover layer for the display may have an image transport layer such as an image transport layer formed from optical fibers. Extruded filaments of binder material may be fused together to form a layer of binder for the image transport layer. Each filament may contain multiple embedded optical fibers. As a result of the extrusion process, the optical fibers may be characterized by increasing lateral deformation at increasing distances from the center of the filament in which the optical fibers are embedded. Tension variations and variations in the orientation angle of the fibers in the image transport layer can be maintained below desired limits to ensure satisfactory optical performance for the image transport layer. The optical fibers and binder may be formed from polymers or other clear materials.

Abstract: Shield structures with reduced spacing between adjacent insulation components and systems and methods for making the same are provided. In some embodiments, different insulation components of different layers of a stack may be attached to the same surface of a shield component during a single attachment (e.g., lamination) operation to attenuate the spacing between the different insulation components attached to the shield component. Limiting the size of a spacing between adjacent insulation components along a shield component of a shield structure may limit the size of an exposed portion of the shield component, which may limit the opportunity for that exposed shield component portion to be shorted to another structure (e.g., a support structure of an electronic device that includes the shield structure).
