  • Patent number: 8077123
    Abstract: Compensation needed to be made for reduced light efficiency in aged sub-pixels of an active matrix organic light-emitting diode (OLED) display are determined using a current ratio or a voltage ratio pertaining to an aged sub-pixel relative to un-aged, reference sub-pixels. When the current through the sub-pixels or the voltage across the sub-pixels are measured to determine the age of the sub-pixels, correction is made to the measured current or voltage to account for variations in the ambient temperature in which the OLED display is placed.

  • Publication number: 20110240368
    Abstract: In certain embodiments, a steerable drilling tool is provided including a rotatable shaft extending through a housing where the shaft and the housing are separated by at least one bearing or two sets of bearings, the shaft having a first portion terminating at a first end of the shaft and a second portion terminating at a second end of the shaft. The steerable drilling tool may further include a drill bit structure operatively coupled to the first portion and a steering subsystem comprising a pair of bearings operatively coupled to the first portion. The steering subsystem may be configured to angulate the shaft by exerting force substantially through the pair of bearings. In certain embodiments, the first portion is between the first end and about one-third of the length of the shaft from the first end towards the second end.

  • Publication number: 20090195483
    Abstract: A plurality of gray level versus OLED current curves are generated by measuring many OLED panels from a stable manufacturing process, and those curves are stored as standard gray level versus OLED current curves. When a new OLED display is manufactured from the process, each of its sub-pixels is characterized as having the characteristics of one of the pre-generated standard gray level versus OLED current curves, based on a gray level versus OLED current measurement at a single gray level. This drastically reduces the time it takes to determine the TFT gate voltage versus OLED current characteristics of the sub-pixels in the OLED display. The OLED display can use the selected one of the pre-generated standard gray level versus OLED current curves to correct non-uniformities of the sub-pixels in the OLED display caused by non-uniform TFTs in the active matrix.

  • Publication number: 20080266214
    Abstract: An active matrix drive system drives an emissive display device such as an organic light-emitting diode display and is configured to measure sub-pixel current in the emissive display device. One or more power column power lines of the emissive display device are turned off while sub-pixel current is measured. As a result, the sub-pixel current is relative large compared to the background current of the emissive display device, which facilitates accurate measurement of the sub-pixel current.

  • Publication number: 20080231566
    Abstract: The current drivers of an emissive display device such as an OLED display are shut off to have minimum drain current when sub-pixel current is measured, in order to minimize dark current during sub-pixel current measurement. The current drivers in the sub-pixels not under test are biased in such a manner as to reduce their leakage current to a minimum. Therfore, the signal to noise ratio between the OLED sub-pixel current and the panel dark current can be maximized.

  • Patent number: 7283888
    Abstract: Method and system for a direct transmission of motion path data (310) from a generating system (204) to a control system (205) for use in controlling a servo-driven machine. For example, a machine tool for machining stock material, and the data generating system includes a computer-aided-design software package (301). Tool paths for directing the tool members of the machine tool can be extracted from a design file opened by the CAD software through the operation interface of the CAD software (302). Alternatively, the design file can be used to specify motion paths rather than end product geometry. The CAD interpreter application extracts the motion path data from the design file, eliminating the need to translate the data into another or intermediate form for controlling the machine tool.
