    摘要: An organic light emitting display includes a current driving unit, an organic light emitting diode and a memory unit. The current driving unit is employed to provide a driving current according to a driving voltage generated therein. The organic light emitting diode generates a light output based on the driving current. The operation of the memory unit is controlled by a first auxiliary power voltage and a second auxiliary power voltage. When the first auxiliary power voltage is greater than the second auxiliary power voltage, the memory unit is enabled to perform a voltage retaining operation on the driving voltage. When the second auxiliary power voltage is greater than the first auxiliary power voltage, the memory unit is disabled for ceasing the voltage retaining operation.

The first shift registering unit generates a first trigger signal at a first output terminal and includes a first pull-down circuit. The second shift registering unit receives the first trigger signal and generates a second trigger signal at a second output terminal.

    摘要: A shift register and a shift register unit for diminishing clock coupling effect are introduced herein. Each stage shift register unit includes at least one pull-up driving module, a pull-up module, at least one pull-down module and a pull-down driving module. Before a waveform of either a first clock signal or a second clock signal employed by the pull-up module transits into a rising edge, the pull-down driving module employs a first periodic signal to turn on the pull-down module in advance for a specific period, and/or before the waveform of the first or second clock signal employed by the pull-up module transits into a falling edge, the pull-down driving module employs a second periodic signal to turn off the pull-down module in advance for a specific period. Accordingly, the pull-down module can gain a sufficient capability against the clock coupling effect so as to optimize the waveform outputted from the shift register unit.

    摘要: The present invention provides a method to reduce the power consumption. The method comprises these steps. First, the RGB gray levels of a pixel are decided. Then, the RGB gray level values are transformed to XYZ tristimulus values. The XYZ tristimulus values are transformed to L*a*b* values. Next, the L*′a*′b*′ values are determined based on an acceptable color difference range. The color difference between the L*′a*′b*′ and the L*a*b* is in the color difference range. Finally, the L*′a*′b*′ values are transformed to X′Y′Z′ values and the X′Y′Z′ values are transformed to R′G′B′ gray level values.

    摘要: In one aspect of the invention, a method of driving an OLED display includes providing scan signals and data signals and applying the scan signals to scan lines and the data signals to the data lines, respectively. Each scan signal is characterized with a waveform having a compensation duration and a scan duration immediately following the compensation duration. The waveform has a first voltage and a second voltage periodically and alternately varied from one another defining a period in the compensation duration, and has the first voltage in the scan duration. The period is equal to the scan duration but shorter than the compensation duration. As such, during the compensation duration of a scan signal, pixels of a corresponding pixel row are charged for compensation, and during the scan duration, the data signals are written into the pixels of the corresponding pixel row for driving the OLEDs thereof.
