Classification: CPC G | IPC G

Claim 13:
14. A display device comprising:
a display panel in which a first display region having a first light transmittance and a second display region having a second light transmittance higher than the first light transmittance are defined; and
a drive controller which receives an input image signal and outputs a data signal to be provided to the display panel,
wherein the drive controller classifies the input image signal into a first image signal corresponding to a first pixel unit in the first display region of the display panel and a second image signal corresponding to a second pixel unit and a non-pixel unit adjacent to the second pixel unit in the second display region of the display panel,
wherein the drive controller generates a data histogram by classifying the second image signal based on a plurality of gray levels and selects a first algorithm or a second algorithm different from the first algorithm based on the number of second image signals included in a part of the plurality of gray levels of the data histogram,
wherein the first algorithm calculates a first result value by computing the second image signal and a preset kernel matrix, and the second algorithm calculates a second result value less than the first result value, based on the first result value, and
wherein the drive controller outputs a first data signal corresponding to the second pixel unit in the second display region when the first algorithm is selected, and the drive controller outputs a second data signal corresponding to the second pixel unit in the second display region based on the second result value when the second algorithm is selected.
