    Abstract: A light emitting diode (LED) display can calculate a common voltage charge of a line of pixels in the LED display, the common voltage charge comprising a difference between a first line of pixels and a second line of pixels. If the calculated common voltage charge exceeds a predetermined threshold, a toggle matrix can be generated for the line of pixels. The toggle matrix can include a matrix of charge values generated by calculating a difference in charge values for each subpixel a first line of subpixels with each subpixel a second line of subpixels. The LED display can identify one or more regions of subpixels exhibiting the predetermined toggle pattern in the toggle matrix. The LED display can generate a voltage correction charge to apply to affected regions of the display. Alternatively, the subpixels or pixels could be swapped with adjacent pixels to reduce toggling or settling error.

    Abstract: An apparatus includes a non-volatile storage circuit that includes a primary copy of a data value in a first storage location and a redundant copy of the data value in a second, different storage location. The data value includes one or more bits. The apparatus further includes an error detection circuit configured to retrieve contents of the first and second storage locations in response to a request for the data value. The error detection circuit is further configured to perform an error correction operation on the retrieved contents of the first and second storage locations to generate a data output responsive to the request, and to perform an error detection operation to generate an error signal that indicates whether the retrieved contents of the first and second storage locations are different.

    Abstract: An electronic device may include a display having an array of display pixels and having display control circuitry that controls the operation of the display. The display control circuitry may operate the display in different modes. In a paper mode, display control circuitry may use stored spectral reflectance data to adjust display colors such that the colors appear as they would on a printed sheet of paper. In a low light mode when the ambient light level is below a threshold, the light emitted from the display may be adjusted to mimic the appearance of an incandescent light source. In a bright light mode when the ambient light level exceeds a threshold, the light emitted from the display may be adjusted to maximize readability in bright light. The target white point of the display may be adjusted based on which mode the display is operating in.

    Abstract: An electronic device may be provided with a display cover layer mounted to the device using an adhesive bond with a display. The display may be a flexible display. The flexible display may include Organic Light Emitting Diode display technology. The display may be mounted to a rigid support structure. The rigid support structure may be mounted to a device housing member. Mounting the display cover layer to the display may eliminate the need to mount the display cover layer to the device housing and may allow active display pixels to be visible under the display cover layer closer to the device housing than in conventional devices. Providing the electronic device with active display pixels closer to the device housing may reduce the need for an inactive border around the display and may improve the aesthetic appeal of the electronic device.

    Abstract: An electronic device may be provided with a display that has a layer of liquid crystal material interposed between a color filter layer and a thin-film-transistor layer. The thin-film-transistor layer may have a substrate with an upper surface and a lower surface. A circular polarizer may be formed on the upper surface. Thin-film transistor circuitry such as gate driver circuitry may be formed on the lower surface. A display driver circuit may be mounted on an inactive border region of the lower surface of the thin-film transistor substrate. Display pixels may form an array in a central active region of the display. A grid of metal gate and data lines may distribute signals from the display driver circuit and gate driver circuitry to the display pixels. A grid of non-reflecting lines may be interposed between the grid of metal lines and the lower surface.

    Abstract: A display has an array of display pixels formed from display layers such as one or more polarizer layers, a substrate on which an array of display pixel elements such as color filter elements and downconverter elements are formed, a liquid crystal layer, and a thin-film transistor layer that includes display pixel electrodes and display pixel thin-film transistors for driving control signals onto the display pixel electrodes to modulate light passing through the display pixels. A light source such as one or more laser diodes or light-emitting diodes may be used to generate light for the display. The light may be launched into the edge of a polymer layer or other light guide plate structure. A light guide plate ma include phase-matched structures such as holographically recorded gratings or photonic lattices that direct the light upwards through the array of display pixels.
