  • Publication number: 20140375700
    Abstract: In a display device (110) provided with pixel circuits including organic EL elements, a display control circuit (1) calculates a voltage drop amount VRI of a power line due to display for each frame on the basis of an integrated value for display data, and a tone voltage generation circuit (9) adjusts reference voltages for a tone voltage on the basis of the integrated value in order to compensate for the voltage drop amount VRI. As a result, it is possible to compensate for the voltage drop of the power line with accuracy without increasing power consumption and the wiring in the pixel circuits.

  • Publication number: 20140375622
    Abstract: A scanning order calculating portion (23) included in a display control circuit (200) determines the order of selecting all rows by repeating the following: the row for which the total amount of potential variation relative to a reference row is the lowest is selected as a subsequent row, and the row having been selected as the subsequent row is used as the next reference row in a similar operation to determine the next row to be set as a subsequent row. A scanning order setting portion (24) controls an address outputting portion (26) such that the scanning signal lines are selected in the determined order, and also controls digital image signals DV outputted by output frame memory (22). Power consumed by driving video signal lines can be reduced by selecting the scanning signal lines in such an order that the total amount of potential variation of the video signal lines becomes smaller.

  • Patent number: 8918853
    Abstract: Automatic recovery from loss of a security token on an embedded device is achieved by having a service provider (SP) server send to a device server a backup copy of the security token in conjunction with sending to an embedded device a primary copy of the security token, and retrieving from the device server and sending to the embedded device the backup copy of the security token upon detecting that the primary copy of the security token has been lost. The method and system obviate the need for a user to have to re-input on the embedded device a credential that is represented by the security token in the event the primary copy of the security token is erased from the embedded device or otherwise becomes inaccessible to the embedded device.
