摘要： Display layers and touch sensor layers may be overlapped by enclosure walls in an electronic device. The electronic device may have a front wall and opposing rear wall and curved sidewalls. The front wall and the curved sidewalls may be formed from a glass layer or other transparent member. A touch sensor layer and display layer may extend under the glass layer with curved sidewalls. A touch sensor layer may also extend under the opposing rear wall. A foldable electronic device may have a flexible transparent wall portion that joins planar transparent walls. Components may be interposed between the transparent planar walls and opaque walls. Display and touch layers may be overlapped by the transparent walls and the transparent flexible wall portion. Touch sensor structures may also be overlapped by the opaque walls.

摘要： An electronic device may include a display. The display may be formed by an array of light-emitting diodes mounted to the surface of a substrate. The substrate may be a silicon substrate. Circuitry may be located in spaces between the light-emitting diodes. Circuitry may also be located on the rear surface of the silicon substrate and may be coupled to the array of light-emitting diodes using through-silicon vias. The circuitry may include integrated circuits and other components that are attached to the substrate and may include transistors and other circuitry formed within the silicon substrate. Touch sensor electrodes, light sensors, and other components may be located in the spaces between the light-emitting diodes. The substrate may be formed from a transparent material that allows image light to reach a lens and image sensor mounted below the substrate.

摘要： Disclosed herein are liquid-crystal display (LCD) touch screens that integrate the touch sensing elements with the display circuitry. The integration may take a variety of forms. Touch sensing elements can be completely implemented within the LCD stackup but outside the not between the color filter plate and the array plate. Alternatively, some touch sensing elements can be between the color filter and array plates with other touch sensing elements not between the plates. In another alternative, all touch sensing elements can be between the color filter and array plates. The latter alternative can include both conventional and in-plane-switching (IPS) LCDs. In some forms, one or more display structures can also have a touch sensing function. Techniques for manufacturing and operating such displays, as well as various devices embodying such displays are also disclosed.

摘要： An electronic device display may have a color filter layer and a thin film transistor layer. A layer of liquid crystal material may be interposed between the color filter layer and the thin film transistor layer. A layer of polarizer may be laminated onto the surface of the color filter layer. Laser trimming may ensure that the edges of the polarizer are even with the edges of the color filter layer. The thin film transistor layer may have an array of thin film transistors that control pixels of the liquid crystal material in the display. Driver circuitry may be used to control the array. The driver circuitry may be encapsulated in a planarized encapsulant on the thin film transistor layer or may be mounted to the underside of the color filter layer. Conductive structures may connect driver circuitry on the color filter layer to the thin film transistor layer.

摘要： An electronic device with a force sensing device is disclosed. The electronic device comprises a user input surface defining an exterior surface of the electronic device, a first capacitive sensing element, and a second capacitive sensing element capacitively coupled to the first capacitive sensing element. The electronic device also comprises a first spacing layer between the first and second capacitive sensing elements, and a second spacing layer between the first and second capacitive sensing elements. The first and second spacing layers have different compositions. The electronic device also comprises sensing circuitry coupled to the first and second capacitive sensing elements configured to determine an amount of applied force on the user input surface. The first spacing layer is configured to collapse if the applied force is below a force threshold, and the second spacing layer is configured to collapse if the applied force is above the force threshold.

摘要： A touch sensor panel having co-planar single-layer touch sensors fabricated on a single side of a substrate is disclosed. The drive and sense lines can be fabricated as column-like patterns in a first orientation and patches in a second orientation, where each column-like pattern in the first orientation is connected to a separate metal trace in the border area of the touch sensor panel, and all patches in each of multiple rows in the second orientation are connected together using a separate metal trace in the border area of the touch sensor panel. The metal traces in the border areas can be formed on the same side of the substrate as the patches and columns, but separated from the patches and column-like patterns by a dielectric layer.

摘要： A display may have an array of pixels with light-emitting diodes that emit light to form images. The display may have a substrate with thin-film transistor circuitry for supplying signals to the light-emitting diodes. Anodes may be formed on the thin-film transistor circuitry, emissive material may be formed on the anodes, and a cathode layer may overlap the anodes. During operation, currents may flow between the anodes and the cathode layer to illuminate the diodes. An array of electrical components such as an array of light sensors in an integrated circuit may be mounted under the substrate. An array of corresponding light transmitting windows may be formed in the display each of which may allow light to pass through the display to a corresponding one of the light sensors. Light transmitting windows may be formed by patterning the cathode layer and supplying the windows with antireflection layers.
