摘要： A current controller for an output stage of light emitting diode (LED) driver circuitry includes a current source establishing a nominal amount of current available for each member of the set of channels. The nominal amount of current is based on, e.g., a desired brightness level. Pulse width modulation (PWM) circuitry is electrically coupled to the current source and is configured to control durations in which adjusted amounts of current are applied to corresponding members the set of LEDs. Compensation circuitry is electrically coupled to the current source and the PWM circuitry. The compensation circuitry includes a set of switching elements to adjust, for each corresponding member of the set of LEDs, the nominal amount of current and thereby provide to the PWM circuitry the adjusted amounts of current based on feedback representing one or both load impedance variations and parasitic conditions (LIVPC) and process, voltage and temperature (PVT) conditions.

摘要： A micro-optical element is produced through vapor deposition techniques, such as atomic layer deposition. An optical structure having a surface with uneven structures is exposed to one or more precursor vapors to create a self-limiting film growth on the surface of the optical structure. The film thickness may be increased and controlled by subsequent exposures. The resulting film conforms to surface structures having varying complex dimensions.

摘要： An AC thin film electroluminescent (TFEL) device includes a multilayer phosphor for emitting white light having improved emission intensity in the blue region of the spectrum. The multilayer stack consists of an inverted structure thin film stack having a red light emitting manganese doped zinc sulfide (ZnS:Mn) layer disposed on a first insulating layer; a blue-green light emitting cerium doped strontium sulfide (SrS:Ce) layer disposed on the red light emitting layer; and a blue light emitting cerium activated thiogallate phosphor (Sr.sub.x Ca.sub.1-x Ga.sub.2 S.sub.4 :Ce) layer disposed on the blue-green light emitting layer. The manganese doped zinc sulfide layer acts as a nucleating layer that lowers the threshold voltage, and the cerium activated thiogallate phosphor layer provides a moisture barrier for the hydroscopic cerium doped strontium sulfide layer. The white light from the multilayer phosphor can be appropriately filtered to produce any desired color.

摘要： An electroluminescent display having a plurality of layers including at least a transparent electrode layer, a rear electrode layer, and at least three layers including an electroluminescent layer sandwiched between front and rear dielectric layers. All three layers thereof are disposed between the rear electrode layer and the transparent electrode layer wherein the transparent electrode layer is formed on a transparent substrate, so as to emit light upon the application of an electric field between the transparent electrode layer and the rear electrode layer. A thin-film absorption layer that absorbs a substantial percentage of light incident thereon is disposed between the rear electrode layer and the rear dielectric layer. The thin-film light absorption layer includes a first absorption portion having a complex refractive index that substantially matches the complex refractive index of the rear dielectric layer where they are adjacent and a second absorption portion having a complex refractive index that substantially matches the complex refractive index of the rear electrode layer where they are adjacent. In one embodiment the thin-film light absorption layer is a single layer having a complex refractive index which gradually changes. In an alternate embodiment the thin-film light absorption layer is composed of a plurality of discrete layers.
