    摘要： Circuits for programming a circuit with decreased programming time are provided. Such circuits include a storage device such as a capacitor for storing display information and for ensuring a driving device such as a driving transistor drives a light emitting device according to the display information. To increase programming time, the pixel circuits may be pre-charged or a biasing current may be applied to charge and/or discharge a data line and/or the driving device. Aspects of the present disclosure allow for the biasing current to drain partially through the storage device to allow the portion of the biasing current applied to the driving device to remain small while the data line discharges. Furthermore, the present disclosure provides display architectures and operation schemes for display arranged in segments each including a plurality of pixel circuits.

    摘要： A system extracts effective parameters from a pixel circuit that includes a light emitting device, a drive device to provide a programmable drive current to the light emitting device, a programming input, and a storage device to store a programming signal. The system measures the value of at least one operating parameter of the pixel circuit at a plurality of levels, and then extracts the value of at least one related parameter of the pixel circuit, based on the measured values of the at least one operating parameter. The measured values of the operating parameter are translated to effective values for driving the pixel circuit, based on the extracted value. Then effective parameters for driving effective devices in the pixel circuit are extracted, based on the translated values, and stored for use in compensating input signals to the pixel circuit.

    摘要： Systems and methods detect and compensate for process or performance-related non-uniformities and/or degradation in displays. The systems and methods can compare a device current with one or more reference currents to generate an output signal indicative of the difference between the device and reference currents. This output voltage can be amplified, and quantized and then be used to determine how the device current differs from the reference current and to adjust the programming voltage for the device of interest accordingly.

    摘要： A gate driver suitable for integration with the backplane of an AMOLED display includes first and second clock signal sources producing first and second clock signals each having alternating active and inactive portions configured such that when one of the clock signals is active the other of the clock signals is inactive, and active portions of the first and second clock signals do not overlap. In a daisy chain of circuits for producing gate signals, each of the circuits except the last has an output coupled to the input of the next circuit in the chain. A source of a start token signal is coupled to an input of a first circuit in the daisy chain. Each of the circuits is configured to produce a gate signal one clock cycle after an active portion of one of the clock signals is received.

    摘要： The OLED voltage of a selected pixel is extracted from the pixel produced when the pixel is programmed so that the pixel current is a function of the OLED voltage. One method for extracting the OLED voltage is to first program the pixel in a way that the current is not a function of OLED voltage, and then in a way that the current is a function of OLED voltage. During the latter stage, the programming voltage is changed so that the pixel current is the same as the pixel current when the pixel was programmed in a way that the current was not a function of OLED voltage. The difference in the two programming voltages is then used to extract the OLED voltage.

    摘要： A system reads a desired circuit parameter from a pixel circuit that includes a light emitting device, a drive device to provide a programmable drive current to the light emitting device, a programming input, and a storage device to store a programming signal. One embodiment of the extraction system extracts a parasitic capacitance value from a pixel circuit by measuring at least one parameter of the pixel circuit when in a first state having a first set of operating voltages and currents, measuring at least one parameter of the pixel circuit when in a second state having a second set of operating voltages and currents different from the first set, and extracting the value of a selected parasitic capacitance from the measurements.
