  • Publication number: 20060145969
    Abstract: A method is provided of determining the pixel drive signals to be applied to the pixels of an array of light emitting display elements arranged in rows and columns, with a plurality of the pixels in a row being supplied with current simultaneously along a respective row conductor. Target pixel drive currents are determined from a model of the pixel current-brightness characteristics. These are modified to take account of the voltage on the respective row conductor at each pixel resulting from the currents drawn from the row conductor by the plurality of pixels and the dependency of the pixel brightness characteristics on the voltage on the row conductor at the pixel. This addresses the problem of horizontal cross-talk that occurs in active matrix 1.RD displays due to the finite output impedance of the current providing TFT's as well as the finite resistance of metals used to form power supply lines.

  • Publication number: 20060146211
    Abstract: A display device has pixels 41 arranged in rows and columns 42,44 addressed by a grid of first and second addressing conductors 50,52. The addressing conductors 50,52 are not parallel with the pixel rows or pixel columns 42,44. This arrangement decouples the row and columns of pixels from the addressing conductors. This provides freedom in the positioning of the driver circuits, which are positioned at the ends of the first and second conductors, which in turn gives greater design freedom for the shape and position of the display in a product.

  • Publication number: 20060097965
    Abstract: 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.

  • Publication number: 20060072061
    Abstract: In an active matrix display device, particularly an AMLCD, having an array of display pixels (8) and comprising pixel electrodes (16), associated switches (22), and address lines (18, 20) carried on a first substrate (10), a common electrode (26) carried on a second substrate (12), a drive circuit (40, 80) carried on the first substrate (10) including at least one conductor line (96) providing a drive voltage for the common electrode (26) and to which the common electrode (26) is connected (92), the common electrode (26) on the second substrate is utilised to provide also electrical connection between the one conductor line (96) and at least one other circuit element (37) carried on the first substrate (10). The use of the common electrode in this way assists in avoiding problems due to resistances of connections formed on the first substrate. The connection to a storage capacitor line (37, 36) may benefit especially.

  • Publication number: 20060066553
    Abstract: An active matrix display device, particularly a liquid crystal display device, having an array of display pixels (25) driven with inverting polarity drive voltages includes correction means (40, 55) for providing a measurement indicative of a DC voltage level at the pixels (25), for example caused by kickback effects, and modifying pixel drive voltages accordingly so as to compensate for any display artefacts. The correction means includes a plurality of measurement pixels (40), each comprising one or more dummy display pixels, which are arranged at spaced locations along at least one side of the pixel array (45) and which supply independent measurements indicative of the behaviour of display pixels in their neighbourhood. The correction means is then able, for example, to account for variations in pixel DC levels over the array.

  • Publication number: 20060064612
    Abstract: An IC arrangement (200) has a plurality of IC modules (220a, 220b), the individual IC modules (220a, 220b) being coupled between a first power line (202) and a second power line (204) via a voltage generator (240a, 240b). The voltage generators (240a, 240b) are powered via the first power line (202) and the second power line (204) and are arranged to regenerate a reference voltage on a reference power line (106) for providing the IC modules (220a, 220b) with the regenerated voltage on respective internal power lines (222a, 222b). A feedback loop (242a, 242b) from the internal power lines (222a, 222b) to the voltage generator (240a, 240b) ensures that the voltage on the internal power lines (222a, 222b) remains substantially constant, even if substantial current fluctuations on the first power line (202), the second power line (204) or the internal power line (222a, 222b) occur. The IC arrangement (200) is particularly suitable as a driver circuit for a matrix array device.

  • Publication number: 20050110764
    Abstract: A portable electronic device (40) comprises a display module (42) and a battery unit (44). The device has at least one further analogue input or output interface (50,52,54) (in addition to the display). The display module includes a voltage converter (48) for providing at least one voltage exceeding the battery unit voltage, and an output from the voltage converter (48) of the display module is provided to a circuit (50a, 52a, 54a) associated with the at least one further analogue input or output interface. This enables a reduction in cost and volume of the device by providing a highly integrated solution, in which a voltage converter within a display module is used also for circuitry of another interface or interfaces.

  • Publication number: 20030154285
    Abstract: A method and system for using an Ethernet ring topology to connect Ethernet Computer Enclosure Services (CES) devices. The system contains two physical Ethernet tailstock connectors for every CES device on the Ethernet ring for point-to-point connection between Ethernet Network Interface Cards (NIC's) connected to each CES device. A master CES device initiates all network traffic, and the master CES device assigns IP addresses for all CES devices, including both the master CES device as well as slave CES devices on the Ethernet ring. After IP addresses are assigned to all CES devices, a network command is issued by the master CES device on a regular basis to poll the slave CES devices for status and failure information. If a break occurs anywhere in the ring, the master CES device isolates and identifies the break and reverses the direction of the polling signal to access each slave CES device.

  • Patent number: 6061933
    Abstract: To compact soil, an impact apparatus includes a weight within a steel frame that may be carried by a vehicle mounted backhoe and placed over the surface to be compacted or broken. The weight is lifted and released by a cable. To pull the cable, a hydraulic cylinder pushes one set of pulleys upwardly away from another set with the upper set of pulleys including five pulleys and the lower set including four pulleys to provide a multiplication factor. The end of the cable opposite the end attached to the weight is attached to the movable pulleys, all of which are mounted at an elevation higher than the fixed pulleys so that the pulley assembly, the attached cable end, the hydraulic cylinder ram and piston, and the weight fall downwardly under the force of gravity.
