  • Patent number: 11694588
    Abstract: Disclosed are a low power driving system and timing controller for a display device. The low power driving system for a display device may include a timing controller configured to transmit a packet to which one of first option information corresponding to a static pattern or second option information corresponding to a dynamic pattern is applied, and a source driver configured to receive the packet and to perform a low power mode corresponding to the static pattern based on the first option information or adaptive charge sharing corresponding to the dynamic pattern based on the second option information.
    Type: Grant
    Filed: December 15, 2020
    Date of Patent: July 4, 2023

  • Patent number: 8192516
    Abstract: Disclosed is a filter cassette magazine and an apparatus for sequentially gathering fine particles using the same, in which a ‘filter cassette not having gathered fine particles yet,’ is received from a first magazine and the received filter cassette is transferred to a lower portion of an upper filter holder, the ‘filter cassette not having gather fine particles yet’ is pushed up toward the upper filter holder by lifting a lower filter holder so as to gather fine particles from outside, the ‘filter cassette having gathered fine particles’ is transferred to a lower portion of a second magazine, and the ‘filter cassette having gathered fine particles’ is pushed up and stored into the second magazine by lifting a push rod. Therefore, it is possible to implement simple maintenance and management, reduction in malfunction, and reduction in parts for machines and equipment.
