Abstract: A display device includes a processor and a display panel for receiving observation grayscale values from the processor. The display panel includes a data driver for applying data voltages to data lines, a target pixel coupled to at least one of the data lines, and observation pixels each coupled to at least one of the data lines, and located adjacent to the target pixel. The display panel applies a first data voltage to the target pixel, when the observation grayscale values for the observation pixels exceed a reference value. The display panel applies a second data voltage to the target pixel, when at least one of the observation grayscale values does not exceed the reference value. The first data voltage and the second data voltage are different from each other.

Abstract: A display device includes a display panel including pixels coupled to a first scan line and a data line, a power supply to supply voltages, a scan driver to provide a first scan signal to the first scan line a plurality of times for a first frame period (FFP), a data driver to supply a data signal to the data line, and a timing controller to control driving of components. The FFP includes: a first active period (FAP), in which the data signal is supplied; and a first blank period (FBP), in which the data signal is not supplied. The power supply provides on-bias power having a first voltage level (FVL) in the FAP, and provides on-bias power having a second voltage level (SVL) in the FBP. The FBP following the FAP includes a first dimming period in which the on-bias power gradually changes from the FVL to the SVL.
