Abstract: Pixels in an organic light-emitting diode (OLED) display may be microcavity OLED pixels having optical cavities. The optical cavities may be defined by a partially transparent cathode layer and a reflective anode structure. The anode of the pixels may include both the reflective anode structure and a supplemental anode that is transparent and that is used to tune the thickness of the optical cavity for each pixel. Organic light-emitting diode layers may be formed over the pixels and may have a uniform thickness in each pixel in the display. Pixels may have a conductive spacer between a transparent anode portion and a reflective anode portion, without an intervening dielectric layer. The conductive spacer may be formed from a material such as titanium nitride that is compatible with both anode portions. The transparent anode portions may have varying thicknesses to control the thickness of the optical cavities of the pixels.

Abstract: 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.

Abstract: An electronic device may have a display that is protected by a transparent cover layer. The transparent cover layer may include a laser-annealed sapphire coating on the outer surface of a glass substrate or other transparent substrate. The sapphire coating may provide the display with a hard, scratch-resistant outer surface. The sapphire coating may be formed by coating a glass substrate with a thin film of amorphous aluminum oxide. The aluminum oxide thin film may be locally heated to transform the amorphous aluminum oxide into alpha-phase aluminum oxide (sapphire). Local heating may be achieved by laser annealing the aluminum oxide coating with a carbon dioxide laser. The laser may produce laser light having a wavelength that is absorbed in the aluminum oxide coating without being absorbed by the glass substrate so that the glass substrate is not damaged during the laser annealing process.

Abstract: Sputter deposition systems and methods for depositing film coatings on one or more substrates are disclosed. The systems and methods are used to prevent or reduce an amount of defects within a deposited film. The methods involve removing defect-related particles that are formed during a deposition process from certain regions of the sputter deposition system and preventing the defect-related particles from detrimentally affecting the quality of the deposited film. In particular embodiments, methods involve creating a flow of gas from a deposition region to a particle collection region the sputter deposition system such that the defect-related particles are entrained within the flow of gas and away from the deposition region. In particular embodiments, the sputter deposition system is a meta-mode sputter deposition system.
