Abstract: A light-emitting layer structure that maximizes constructive interference for light emission by varying a phase shift introduced by reflective electrodes. The light-emitting layer structure includes a first and second optical cavity including a first and second reflective electrode; a first and second partially transparent electrode; and a first and second emissive layer (EML) disposed between the first and second reflective electrodes and the first and second partially transparent electrodes, wherein the first EML emits light having a first wavelength; wherein the first reflective electrode introduces a first phase shift, depending on the first wavelength, on reflection of light emitted by the first EML; and wherein the second EML emits light having a second wavelength and the second reflective electrode introduces a second phase shift, depending on the second wavelength, on reflection of light emitted by the second EML, and the first phase shift is different from the second phase shift.

Abstract: A display system includes a display panel comprising a plurality of pixel circuits, and a measurement and data processing unit that is external to the display panel. Each pixel circuit includes a light-emitting device having a first terminal connected to a first voltage supply and a second terminal opposite from the first terminal; a first transistor connected between a data voltage supply line from the measurement and data processing unit and the second terminal of the light emitting device; and a second transistor connected between the second terminal of the light-emitting device and a sample line to the measurement and data processing unit. The measurement and data processing unit samples a measured voltage at the second terminal of the light-emitting device through the sample line and outputs a data voltage to the light-emitting device based on the measured voltage to compensate variations in properties of the light-emitting device.

Abstract: A light-emitting device is optimized for radiative recombination and minimizes non-radiative recombination. The light-emitting device includes an emissive layer, a first electrode and a second electrode from which charges are generated, a first charge transport layer that injects charges from the first electrode into the emissive layer, and a second charge transport layer that injects charges from the second electrode into the emissive layer. At least one of the charge transport layers includes a mixture of a first nanoparticle population and a second nanoparticle population, and the first nanoparticle population and the second nanoparticle population are conductive nanoparticles that are energetically non-aligned as between the first nanoparticle population and the second nanoparticle population. Nanoparticles of the first nanoparticle population and the second nanoparticle population are energetically non-aligned with each other by being made of different materials, by having nanoparticles of different sizes, and/or by having nanoparticles of different shapes.

Abstract: A pixel circuit for a display device includes a drive transistor configured to control an amount of current to a light-emitting device depending upon a voltage applied to a gate of the drive transistor; a second transistor connected to the gate of the drive transistor and a second terminal of the drive transistor, such that when the second transistor is in an on state the drive transistor becomes diode-connected such that the gate and the second terminal of the drive transistor are connected through the second transistor; a light-emitting device that is connected at a first node to a third terminal of the drive transistor and at a second node to a first voltage supply; a third transistor connected to the first node of the light-emitting device, which connects a data voltage to the first node of the light-emitting device; a fourth transistor that is connected between the second terminal of the drive transistor and a second voltage supply; and at least one capacitor having a first plate that is connected to the gate of the drive transistor and a second plate that is connectable to a reference signal. The pixel circuit is operable during a phase preceding the emission phase including applying a data voltage to the first node of the light-emitting device and the third terminal of the drive transistor, the data voltage being set so that a voltage across the light-emitting device is lower than a threshold voltage of the light emitting device.

Abstract: A measurement device for measuring a concentration of a component of a gas mixture includes a chamber that contains the gas mixture, a light source that emits light into the chamber, the emitted light having a wavelength between 230 nm and 320 nm, and a light sensor that detects a portion of the light from the light source that has propagated through the gas mixture. A processor is configured to determine the concentration of the component of the gas mixture based on the portion of the light emitted from the light source that is detected by the light sensor. The light source may include one or more LEDs, each having a central wavelength of light emission between 270 nm and 320 nm and a linewidth of less than 50 nm. The device may be employed to determine acetone concentration in exhaled breath, which may be indicative of diabetes or other health conditions.
