  • Publication number: 20250056459
    Abstract: A method performed by a User Equipment (UE) for handling timing alignment is provided. The method receives, from a Base Station (BS), a first Radio Resource Control (RRC) message for configuring a Time Alignment Timer (TAT). The method receives, from the BS, a second RRC message for configuring at least one of a cell Discontinuous Transmission (DTX) operation or a cell Discontinuous Reception (DRX) operation. In a case that at least one of the cell DTX operation or the cell DRX operation is configured and the TAT expires, the method considers the UE to be uplink synchronized with the BS and forgoes performing a procedure for handling an out-of-sync condition related to the expiration of the TAT.

    Abstract: The invention provides a display device and an operation method thereof. The display device includes a calculation unit and a local dimming driving unit. The calculation unit generates image data for displaying on a display panel. The calculation unit determines a location of a mouse pointer (cursor) in the image data based on an operation of a user interface device. The calculation unit defines an attention area corresponding to the mouse pointer based on the location of the mouse pointer. Based on information of the calculation unit, the local dimming driving unit enables a local dimming function for the attention area corresponding to the location of the mouse pointer, or disables the local dimming function for a non-attention area outside the attention area.
