Abstract:
An active matrix electroluminescent device provides a gray scale display. The device comprises a first electrode layer including a plurality of individually addressable pixel electrodes, a second electrode layer, and a stack including at least a phosphor layer which produces light upon the application of an electric field across the phosphor layer and a dielectric layer. The stack is disposed between the first and second electrode layers. The second electrode layer is driven during the first subframe time period with a first illumination signal having a first amplitude. At least one of the set of the selected ones of the pixel electrodes is selected with data signals during a subsequent subframe time period of the frame. The second electrode layer is driven,during the subsequent subframe time period with a subsequent illumination signal having a second amplitude or third amplitude where the subsequent amplitude or third amplitude is different than the first amplitude or different than the first amplitude and second amplitude.
Circuit For Controlling The Performance Of An Integrated Circuit
A system and method for utilizing a feedback-based delay stabilization and power optimization circuit. One embodiment of the present invention is directed to an electronic circuit comprising an indicator operable to generate an indicator signal that is proportional to an actual operating speed of an integrated circuit that includes the indicator; and a comparator operable to compare the indicator signal to a reference signal and to generate from the comparison an error signal that is proportional to a difference between the operating speed and a desired operating speed. A signal combining circuit may then generate a feedback signal for a power supply based upon the error signal and an output signal of the power supply.

International Classification:

US Classification:

Abstract:
Optics are utilized in an input device such as a mouse or keyboard, for example, to detect a condition of one or more selection indicators, such as whether a key or button has been depressed or a scroll wheel has been rotated. Depressing a key, clicking a button and/or rotating a scroll wheel cause one or more optical signals to be reflected from the corresponding selection indicator onto an optical detector. The optical detector generates electrical signals in response to the light received by the optical detector. A computational device of the input device processes the electrical signals to determine whether a key or button has been depressed, whether a scroll wheel has been rotated, etc. The corresponding information is then input to a computer that is interfaced with the input device.
Method And Apparatus For Monitoring And Controlling The Thermal Environment And Operating Conditions Of An Integrated Circuit
Logic included in an IC monitors values of parameters that may affect operation of the IC, such as, for example, supply voltage (V), junction temperature (T) and the frequency of a ring oscillator on the IC. In response to the monitored values, the logic in the IC changes, if necessary, one or more parameters such as V, processor frequency (F), and/or cooling level to control the performance of the IC. Thus, the IC monitors its own environment and operating conditions and takes appropriate steps to control its environment and operating conditions to achieve certain goals.

Abstract:
A full color active matrix electroluminescent display includes an active matrix of pixel electrodes, a broad spectrum electroluminescent phosphor stack placed atop the active matrix of pixel electrodes and a transparent electrode placed atop the electroluminescent phosphor stack. A liquid crystal color shutter device is placed atop the transparent electrode for selectively filtering light from the electroluminescent phosphor stack selectively permitting the transmission of red, green or blue colored light in response to commands from a synchronizing circuit that synchronizes the operation of the shutter with the illumination of selected pixels in the active matrix display. Performance is further enhanced by the use of a double notch filter for the white light emitting broad spectrum electroluminescent phosphor so as to provide it with a uniform response at all waves lengths of interest.

International Classification:
G09G 330
US Classification:
345 76
Abstract:
The system illuminates an active matrix EL device (AMEL) to provide a gray scale display. The device includes a first electrode layer comprising an active matrix of individually addressable pixel electrodes, a second electrode layer, and a thin film EL laminate stack including at least an EL phosphor layer and a dielectric layer. The stack is disposed between the first and second electrode layers. A first group of selected pixel electrodes are addressed with data signals during a first subframe time period where the first group includes fewer than all of the pixels electrodes of the display. The second electrode layer is driven during the first subframe time period with a first illumination signal. A second group of selected pixel electrodes are addressed with data signals during a second subframe time period where the second group includes only pixel electrodes not included within the first group. The second electrode layer is driven during the second subframe time period with a second illumination signal.
