Abstract: An electronic device may have a display with backlight structures. The backlight structures may produce backlight that passes through the display layers in the display. The backlight structures may include a light guide plate that distributes light across the display layers. A light source such as a light-emitting diode light source may be used to provide light to the light guide plate. In one suitable embodiment, a light guide structure having a bend may be coupled between the light source and the light guide plate and may be used to guide the light from the light source to the light guide plate via total internal reflection. In another suitable embodiment, the light-emitting diodes may be mounted on a flexible printed circuit that is curled into a spring element. The flexible printed circuit may be used to bias the light-emitting diodes against the edge of the light guide plate.

Abstract: A display may have a first stage such as a color liquid crystal display stage and a second stage such as a monochromatic liquid crystal display stage that are coupled in tandem so that light from a backlight passes through both stages. The dynamic range of the display may be enhanced by using the second stage to perform local dimming operations. The pixel pitch of the second stage may be greater than the pixel pitch of the first stage to ease alignment tolerances and reduce image processing complexity. The color stage and monochromatic stages may share a polarizer. A color filter in the color stage may have an array of red, green, and blue elements or an array of white, red, green, and blue elements. The color stage may be a fringe field display and the monochrome stage may be an in-plane switching display or a twisted nematic stage.

Abstract: The described embodiments relate generally to liquid crystal displays (LCDs), and more particularly to methods for extending a glass portion of a display to an edge of a display housing. In one embodiment, a thin cover glass layer is provided between a color filter glass layer and an upper polarizer. The thin cover glass layer is supported along an edge of the display by a filler material that can include a foam dam and a glass spacer or adhesive filler. The filler material allows the cover glass layer to be supported without damaging any drivers or circuits located on an underlying thin film transistor glass layer. In another embodiment, a glass spacer circuit with integrated drivers and circuitry on its lower surface can support the cover glass along the edge of the display.

Abstract: Systems and methods for operating a display by dynamically determining a refresh rate for the display. In certain implementations, a processor determines a number of pixels having medium grayscale levels from a histogram for the image. If the number does not exceed a threshold, the processor sets a refresh rate for the display to a first refresh rate. In certain implementations, if the number exceeds a threshold, the processor may set the refresh rate for the display to a second refresh rate. Moreover, the first refresh rate may be lower than the second threshold. In some implementations, the image may be analyzed by subdividing the image into blocks and determining a refresh rate based on grayscale levels or distributions in the blocks. Based on the analysis of the blocks, a corresponding refresh rate may be selected.
