    Abstract: An electronic device may be provided with a display having a backlight with light sources of different colors. The electronic device may include a color ambient light sensor that measures the color of ambient light and control circuitry that adjusts the color of light emitted from the backlight based on the color of ambient light. The light sources may include at least first and second light-emitting diodes that emit light having different color temperatures. The control circuitry may adjust the intensity of light emitted from the first light-emitting diode relative to the intensity of light emitted from the second light-emitting diode to produce a backlight color that more closely matches the color of ambient light. The first and second light-emitting diodes may include an ultraviolet light-emitting diode die and a blue light-emitting diode die that are mounted in a common semiconductor package.

    Abstract: A display device is provided. The display device includes a light source emitting a blue light and a light emitting layer including a first group of red quantum dots and a second group of green quantum dots. The light emitting layer is configured to absorb a first portion of the blue light from the light source to emit red light and green light and to transmit a second portion of the blue light. The display device also includes dichroic filter layers to improve light recycling and backlight efficiency.

    Abstract: An electronic device may include display layers such as liquid crystal display layers and a backlight unit that provides illumination for the display layers. The backlight unit may include light-emitting diodes that emit light into the edge of a light guide film. To minimize the inactive area of the display, the light-emitting diodes may be tightly spaced to approximate a line light source instead of point light sources. Color and/or luminance compensation layers may be incorporated at various locations within the backlight structures to ensure that the backlight provided to the display layers is homogenous. A thin-film transistor layer of the display may be coupled to a printed circuit board by a flexible printed circuit. The flexible printed circuit may have additional solder mask layers to improve robustness, may include encapsulation, and may have traces with a varying pitch.

    Abstract: Quantum dot backlights for use in displays and processes for controlling the dimming of quantum dot backlights are provided. The backlight can include an LED (e.g., a blue LED) configured to emit a light through a sheet of quantum dots. The quantum dots can be configured to emit colored light (e.g., red and green light) in response to the light emitted from the LED. To control the relative luminance of the LED, the backlight can be controlled through the use of current dimming to adjust the brightness of the LED at high relative luminance settings to increase the light output efficiency and can include the use of pulse width modulation to adjust the brightness of the LED at low relative luminance settings to reduce the amount of wavelength shift experienced by the LED.

    Abstract: Display backlight structures may provide backlight illumination that passes through display layers in the display. Light-emitting diodes may emit blue light into an edge of a light guide plate. Optical films may overlap the light guide plate. The optical films may include a quantum dot enhancement film. A peripheral strip of yellow reflector or other light control structures may be incorporated into the backlight structures to reduce blue edge effects. The light control structures may have features with a spatially varying density, may be formed from quantum dot enhancement film, or may be formed form other structures. The light control structures may be formed on the surfaces of the optical films, on a reflective layer under the light guide plate, or on a surface of a mold frame or other structure that lies in a plane parallel to the plane of the light guide plate.
