Abstract: A display device includes a data driver, line selectors, and a controller. The data driver provides data signals to output lines. The line selectors control connections between the output lines and data lines. The controller selects a normal driving mode or a low frequency driving mode as a panel driving mode and controls a scan driver, the data driver, and the line selectors based on the panel driving mode. Each line selector respectively connects the output lines to the data lines when the panel driving mode is the normal driving mode, and progressively connects one of the output lines to some of the data lines when the panel driving mode is the low frequency driving mode.

Abstract: A luminance controller according to example embodiments includes a gamma set selector to select a reference gamma set from among first through N-th gamma sets respectively corresponding to first through N-th reference luminances, based on a target luminance of a display panel; an initialization voltage selector to select an initialization voltage corresponding to the reference gamma set, from among first through N-th initialization voltage offsets respectively corresponding to the first through N-th gamma sets; a common voltage selector to select a common voltage corresponding to the reference gamma set from among first through N-th common voltage offsets respectively corresponding to the first through N-th gamma sets; and a determiner to determine a target initialization voltage based on the target luminance and the initialization voltage, and to determine a target common voltage based on the target luminance and the common voltage.
