Abstract: Embodiments of a display device are described. A display device includes first and second sub-pixels. The first sub-pixel includes a first light source having a quantum dot (QD) film, a blocking layer disposed on the QD film, and a first portion of an organic phosphor film disposed on the blocking layer and a first substrate configured to support the first light source. The blocking layer is configured to prevent emission of light from the first portion of the organic phosphor film and the QD film is configured to emit a primary emission peak wavelength in a red, green, cyan, yellow, or magenta wavelength region of an electromagnetic (EM) spectrum. The second sub-pixel includes a second light source and a second substrate configured to support the second light source. The second light source has a second portion of the organic phosphor film disposed adjacent to the QD film.

Abstract: An electronic device may include an electronic display having multiple display pixels to display an image based on analog voltage signals. The electronic device may also include optical calibration circuitry to generate digital-to-analog converter (DAC) data based on image data associated with the image and dither circuitry to reduce a bit-depth of the DAC data, generating dithered DAC data. Additionally, the electronic device may include a gamma generator having one or more DACs to generate the analog voltage signals based on the dithered DAC data, which may instruct the gamma generator to generate the analog voltage signals indicative of the image data.

Abstract: Embodiments of a display device are described. A display device includes first and second sub-pixels. The first sub-pixel includes a first light source having a multi-layer stack and a first substrate configured to support the first light source. The multi-layer stack includes an organic phosphor film or a quantum dot (QD) based phosphor film configured to emit a first light having a first peak wavelength. The first substrate includes a first control circuitry configured to independently control the first light source. The second sub-pixel includes a second light source and a second substrate configured to support the second light source. The second light source has a microLED or a miniLED configured to emit a second light having a second peak wavelength that is different from the first peak wavelength. The second peak wavelength can be in the blue wavelength region of the visible spectrum. The second substrate includes a second control circuitry configured to independently control the second light source.

Abstract: Embodiments of a flexible electroluminescent (EL) device are described. An EL device includes a device stack and a flexible substrate configured to support the device stack. The device stack can include a anode and a cathode, a quantum dot (QD) film positioned between the anode and the cathode and configured to produce light having a first peak wavelength. The device stack further includes a patterned insulating layer disposed on the anode and configured to form electrically active regions in the device stack and to control emission of the light from the EL device through the electrically active regions. The EL device further includes an encapsulation layer disposed on the cathode.
