A micro-light-emitting diode (LED) display includes a number of micro-LED pixel elements and multiple optical sensors integrated with the micro-LED pixel elements. A transparent conductor layer is disposed over the micro-LED pixel elements and optical sensors.

Embedded optical sensors in a micro-led display

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.

Force sensing architectures

Embodiments include a temperature sensing device that includes a temperature sensor stack that includes a flexible substrate and an array of temperature sensors coupled to the flexible substrate. Each temperature sensor in the array of temperature sensors can include a conductive material defining a continuous pattern extending from a first node to a second node, a first set of conductive traces coupled to the flexible substrate, and a second set of conductive traces coupled to the flexible substrate. The temperature sensing device can include a processing circuit configured to apply an electrical signal across the conductive material of each temperature sensor using the first set of conductive traces, detect an effect of the conductive material of each temperature sensor on the electrical signal using the second set of conductive traces, and determine a temperature for the temperature sensors in the array using the detected effects of the conductive material on the electrical signal.

Flexible temperature sensing devices for body temperature sensing

A stylus input device can allow a user to interface with an external electronic device. The stylus can provide an additional or alternative input to the external electronic device in response to a user applying a compressive force to the device housing. The stylus can include multiple sensors to provide a signal in response to the compressive force applied to the stylus.

Stylus with compressive force sensor

An electronic device includes an input device. The input device has an input/output module below or within a cover defining an input surface. The input/output module detects touch and/or force inputs on the input surface, and provides haptic feedback to the cover. In some instances, a haptic device is integrally formed with a wall or structural element of a housing or enclosure of the electronic device.

Electronic device having a touch sensor, force sensor, and haptic actuator in an integrated module

Structures and methods are disclosed for an electronic device having an input surface that uses dual sensors to measure forces applied to the input surface. The forces can be estimated over a greater range of values than would be possible with either sensor alone. A second sensor can be used after a first sensor has reached a limit. A first sensor can be a strain sensor and a second sensor a pressure sensor. Both sensors may be resistance based, with signals from both sensors can be combined and measured by processing circuitry. Each sensor type may be part of planar arrays disposed beneath the input surface.
