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. The second portion of the organic phosphor film is configured to emit a primary emission peak wavelength in a blue, violet, or ultraviolet wavelength region of an EM spectrum.

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.

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.

Display devices with different light sources in pixel structures

Embodiments of the present application relate to the use of quantum dots mixed with spacer particles. An illumination device includes a first conductive layer, a second conductive layer, and an active layer disposed between the first conductive layer and the second conductive layer. The active layer includes a plurality of quantum dots that emit light when an electric field is generated between the first and second conductive layers. The quantum dots are interspersed with spacer particles that do not emit light when the electric field is generated between the first and second conductive layers.

Quantum dot LED with spacer particles

A photodetector has a photoactive layer of semiconducting inorganic nanoparticles positioned between a hole transport electron blocking layer of a first metal oxide and an electron transport hole blocking layer of a second metal oxide. The nanoparticles are responsive to electromagnetic radiation in at least the infrared region of the spectrum. The first metal oxide can be NiO, and the second metal oxide can be ZnO or TiO. The metal oxide layers render the photodetector stable in air, even in the absence of an encapsulating coating around the photodetector. The photodetector has a P-I-N structure.
