  • Patent number: 10600387
    Abstract: A display apparatus and a method for controlling the same are provided. The method for controlling the display apparatus according to the present disclosure includes receiving an image; distinguishing the image into a plurality of blocks to detect a maximum pixel value each of the plurality of blocks; determining a target diffuser value usable for compensating for a duty of a backlight based on the detected maximum pixel value for each block; and driving the backlight for each of the plurality of blocks based on a backlight duty value compensated based on the target diffuser value. Therefore, the display apparatus according to the present disclosure may address a problem that gradation overcompensation occurs in a region of a certain block, when the backlight is driven in a unit of the plurality of blocks, using a local dimming mode.

  • Patent number: 9117386
    Abstract: A method for driving a display panel and a display apparatus applying the same are provided. The method includes driving all lines of the display panel in a first scanning section of a section to display one frame, and driving one of an even line and an odd line of the display panel in a second scanning section of the section to display the one frame. Accordingly, a crosstalk phenomenon in the display apparatus is removed and image quality of a 3D stereoscopic image is improved.

  • Patent number: 7039783
    Abstract: In a dual apparatus and a method thereof using a concurrent write function, a PCI bridge of an active board snoops a processor bus. When a processor carries data and a control signal to the processor bus in order to change content of a memory of the active board, the PCI bridge checks whether data synchronization is required. When the data synchronization is required, the PCI bridge buffers the data and the control signal from the processor bus, and transmits them to a standby board through a PCI bus. Accordingly, the content of the memory of the standby board is changed. While the PCI bridge performs the content change of the memory of the standby board, the processor of the active board changes content of the memory of the active board. Accordingly, a performance of the processor can be improved, and accordingly data synchronization can be performed quickly.

  • Publication number: 20030074534
    Abstract: In a dual apparatus of a communication system, and in particular to a dual apparatus and a method thereof using a concurrent write function, a PCI bridge of an active board snoops a processor bus. When a processor carries data and a control signal to the processor bus in order to change content of a memory of the active board, the PCI bridge checks whether data synchronization is required. When the data synchronization is required, the PCI bridge buffers the data and the control signal from the processor bus, and transmits them to a standby board through a PCI bus. Accordingly, the content of the memory of the standby board is changed. While the PCI bridge performs the content change of the memory of the standby board, the processor of the active board changes content of the memory of the active board. Accordingly, because a load of the processor is lowered, a performance of the processor can be improved, and accordingly data synchronization can be performed quickly.
