  • Publication number: 20250054452
    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.
