Subpixels on an electroluminescent (EL) display panel, such as an organic light-emitting diode (OLED) panel, are compensated for initial nonuniformity (“mura”) and for aging effects such as threshold voltage V_th shift, EL voltage V_oled shift, and OLED efficiency loss. The drive current of each subpixel is measured at one or more measurement reference gate voltages to form status signals representing the characteristics of the drive transistor and EL emitter of those subpixels. Current measurements are taken in the linear region of drive transistor operation to improve signal-to-noise ratio in systems such as modern LTPS PMOS OLED displays, which have relatively small V_oled shift over their lifetimes and thus relatively small current change due to channel-length modulation. Various sources of noise are also suppressed to further increase signal-to-noise ratio.

Pet foods, pet treats and pet supplements with anti-aging effects are disclosed whose compositions include the R-alpha-lipoic acid in the amount of 0.10 grams to 1.5 grams and L-carnitine in the amount of 0.10 grams to 3 grams in addition to the usual composition. Optionally, coenzyme Q can be added in an amount of at least 1 mg/day. Optionally, creatine can be added in an amount of at least 0.2 grams/day. These additional components fight age-related declines in mitochondrial function, which result in less energy and other signs of aging.

A system and method for determining and applying characterization correlation curves for aging effects on an organic light organic light emitting device (OLED) based pixel is disclosed. A first stress condition is applied to a reference pixel having a drive transistor and an OLED. An output voltage based on a reference current is measured periodically to determine an electrical characteristic of the reference pixel under the first predetermined stress condition. The luminance of the reference pixel is measured periodically to determine an optical characteristic of the reference pixel. A characterization correlation curve corresponding to the first stress condition including the determined electrical and optical characteristic of the reference pixel is stored. Characterization correlation curves for other predetermined stress conditions are also stored based on application of the predetermined stress conditions on other reference pixels. The stress condition of an active pixel is determined and a compensation voltage is determined by correlating the stress condition of the active pixel with the curves of the predetermined stress conditions.

The present invention relates to a method for compensating ageing effects of pixel outputs displaying an image on a display device.

Methods and systems to provide baseline measurements for aging compensation for a display device are disclosed. An example display system has a plurality of active pixels and a reference pixel. Common input signals are provided to the reference pixel and the plurality of active pixels. The outputs of the reference pixel is measured and compared to the output of the active pixels to determine aging effects. The display system may also be tested applying a first known reference current to a current comparator with a second variable reference current and the output of a device under test such as one of the pixels. The variable reference current is adjusted until the second current and the output of the device under test is equivalent of the first current. The resulting current of the device under test is stored in a look up table for a baseline for aging measurements during the display system operation. The display system may also be tested to determine production flaws by determining anomalies such as short circuits in pixel components such as OLEDs and drive transistors.

A bulk acoustic wave resonator structure that isolates the core resonator from both environmental effects and aging effects. The structure has a piezoelectric layer at least partially disposed between two electrodes. The structure is protected against contamination, package leaks, and changes to the piezoelectric material due to external effects while still providing inertial resistance. The structure has one or more protective elements that limit aging effects to at or below a specified threshold. The resonator behavior is stabilized across the entire bandwidth of the resonance, not just at the series resonance. Examples of protective elements include a collar of material around the core resonator so that perimeter and edge-related environmental and aging phenomena are kept away from the core resonator, a Bragg reflector formed above or below the piezoelectric layer and a cap formed over the piezoelectric layer.

An electroactive optical device, in particular an electroactive lens, comprising an optical element (1) as well as an electroactive element (2) is described. The optical element (1) is an elastic solid, such as a gel or a polymer. The electroactive element (2) comprises a plurality of compliant electrodes (3a-3e) stacked on top of each other with an electroactive material (5) between them.

Improved device aging monitoring and compensation schemes are presented herein. In particular, embodiments enable quantitative measurement of actual aging experienced by a device up to the instant of measurement, rather than rely on static a priori estimation of aging effects under worst case conditions. As such, embodiments provide adaptive device aging monitoring and compensation schemes. In addition, embodiments allow for aging monitoring and compensation to be performed at a desired granularity, whereby aging monitoring and compensation can be performed at a chip, module, or sub-module level. Further, embodiments inherently compensate for the effects of aging on passive components (e.g., parasitics of interconnect wires, capacitors, etc.) in addition to active device aging.

An impedance compensation circuit for inputs of a programmable device includes programmable impedance circuits connected with input nodes. The programmable impedance circuits can be configured to apply a compensating voltages to input nodes to reduce or eliminate unwanted offset voltages. An impedance compensation circuit may include resistors in series or current sources in parallel. A set of bypass switches selectively apply each resistor or current source to an input node, thereby changing the offset voltage of the node and compensating for impedance mismatches. Control logic provides signals to control the bypass switches. The control logic may be implemented using programmable device resources, enabling the control logic to be updated and improved after the manufacturing of the device is complete. The control logic can automatically evaluate offset voltages at any time and change compensating impedances accordingly. This reduces manufacturing costs and takes into account temperature and aging effects.

Each pixel of an active matrix electroluminescent display device has a first amorphous silicon drive transistor for intermittently driving a current through the display element and a second amorphous silicon drive transistor for intermittently driving a current through the display element. The aging effect of amorphous silicon TFTs can be reduced by sharing the driving of the display element between two drive transistors. Providing a duty cycle reduces the on-time for each drive transistor, but also provides a period during which there can be some recovery of the TFT characteristics.
