Abstract: The present invention relates to the application of a force to enhance the performance of an electrochemical cell. The force may comprise, in some instances, an anisotropic force with a component normal to an active surface of the anode of the electrochemical cell. In the embodiments described herein, electrochemical cells (e.g., rechargeable batteries) may undergo a charge/discharge cycle involving deposition of metal (e.g., lithium metal) on a surface of the anode upon charging and reaction of the metal on the anode surface, wherein the metal diffuses from the anode surface, upon discharging. The uniformity with which the metal is deposited on the anode may affect cell performance. For example, when lithium metal is redeposited on an anode, it may, in some cases, deposit unevenly forming a rough surface. The roughened surface may increase the amount of lithium metal available for undesired chemical reactions which may result in decreased cycling lifetime and/or poor cell performance.

Abstract: An electronic device display may have an inner layer with a pixel array for displaying images and an outer layer with an array of light modulator cells operable in transparent and light-blocking modes.

A block of the cells may be placed into a transparent mode to form a transparent window based on information from the sensor circuitry. Images on the pixel array may be viewed through the window. In another mode of operation, images can be displayed by adjusting the cells of the light modulator layer and backlight illumination may be provided by the pixel array. A camera and a flash or other optical components may be overlapped by an adjustable shutter.

Abstract: An electronic device may have a rollable display. The display may be moved between an unrolled state in which the display is planar and a rolled state in which a rollable portion of the display is rolled up for storage. The display may have a display panel with a pixel array that produces images and a transparent protective layer that overlaps the pixel array. The transparent protective layer may contain a layer of glass. The glass layer may be locally thinned in the rollable portion to facilitate rolling of the display. The display may be configured to apply compressive stress to the outwardly facing surface of the glass layer when the display is rolled up. Compressive stress in the outwardly facing glass surface may help prevent damage to the display when the display is bent during rolling operations.
