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.

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 has improved impact resistance over conventional configurations. Such a light-emitting device includes a display panel layer, a housing layer, an impact absorbing layer adjacent the housing layer, a metal layer that is disposed between the impact absorbing layer and the display panel layer and that is deformable during an impact on the light-emitting device, and a compliant layer that is disposed between the metal layer and the display panel layer that enables a shape of the display panel layer to be maintained when the metal layer is deformed. Due to a compliance or low stiffness of the compliant layer, a permanent deformation of the metal layer due to an impact or device shape change is not discernibly transferred into the shape of the display panel layer, and the shape of the display panel layer is essentially maintained so that an impact or shape change does not adversely affect display performance.

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 method is disclosed for forming an emissive layer of a light-emitting device. One or more layers of the light-emitting device are formed. A solution including quantum dots having ligands at the outer surface thereof is contacted with the uppermost layer of the light-emitting device. A portion of the solution is subjected to external activation stimuli to form a crosslinked layer on the uppermost formed layer of the light-emitting device, the crosslinked layer including the ligands at the outer surface of the quantum dots in a crosslinked state. The solution is washed away, and the crosslinked layer is contacted with ligand exchange solution including compact ligands to perform a ligand exchange. Also disclosed is a light-emitting device including an anode, cathode, and emissive layer disposed therebetween, the emissive layer including quantum dots and compact ligands at the outer surface thereof.
