Abstract: A display device and a method of driving the same are provided. The method of driving the display includes a display area to display an image. The method includes performing a first first pixel shift driving by shifting an image by a first range in the display area without loss of image information due to enlargement or reduction of the image, checking whether a change of a block grayscale value is greater than or equal to a threshold in an interest area in the display area, and performing second pixel shift driving by shifting an image having the loss of image information.

Abstract: A light-emitting element including a first electrode, a second electrode provided on the first electrode, and an emission layer provided between the first electrode and the second electrode, a display device and a fused polycyclic compound are provided. The emission layer includes a fused polycyclic compound that may be a dopant material (e.g., thermally activated delayed fluorescence dopant). The emission layer may further include second to fourth compounds.
The fused polycyclic compound has a pentacyclic core that includes three aromatic rings fused by one boron and two nitrogen atoms. At least one substituent on the pentacyclic core is an electron-donating, tricyclic fused ring and is connected at a para-position with respect to boron. Due to steric demand the molecular shape of the fused polycyclic compound becomes twisted, which results in modulation of the difference between singlet and triplet energy states and the rate of reverse inter-system crossing of the fused polycyclic compound.
