  • DISPLAY DEVICE, METHOD OF DRIVING THE DISPLAY DEVICE, AND ELECTRONIC DEVICE INCLUDING THE DISPLAY DEVICE
    Publication number: 20260141838
    Abstract: A display device includes a display panel including a display region and a display panel driver configured to perform a multi-frequency driving for the display region. The display region includes a first frequency partial region driven at a first frequency and a low frequency partial region driven at a low frequency lower than the first frequency. The display panel driver is configured to determine a driving frequency of the low frequency partial region as a frequency greater than a minimum low frequency based on a position of the low frequency partial region.

  • Secondary battery
    Patent number: 9761845
    Abstract: Provided are a finishing tape, which can prevent a short circuit while preventing impacts applied to an electrode assembly, and a secondary battery including the same. The secondary battery includes a case having an opening defining an internal space, an electrode assembly in the internal space of the case, and a cap assembly coupled to the opening of the case sealing the case. The electrode assembly may include a finishing tape on an outer surface of the electrode assembly between the case and the electrode assembly. The finishing tape may include a first substrate and a second substrate. The cap assembly may include a cap plate coupled to the opening of the case. The secondary battery may further include an insulation case between the electrode assembly and the cap assembly.
