Embodiment Construction

[0047] Hereinafter, the inventive concept will be explained in detail with reference to the accompanying drawings.

[0048] figure 1 is a block diagram illustrating a display device according to an exemplary embodiment.

[0049] refer to figure 1 The display device 100 may include a display panel 110, a timing controller 120, a data driver 130, a scan driver 140, an emission driver 150 (or a light emitting driver), and a power source 160 (or a power supply). The display apparatus 100 may display an image based on image data provided from an external component. For example, the display device 100 may be an organic light emitting display device.

[0050] The display panel 110 may include gate lines S1 to Sn, data lines D1 to Dm, light emission control lines E1 to En, and pixels 111 (or pixel circuits), where each of n and m is an integer greater than or equal to 2. The pixels 111 may be respectively disposed in intersection regions of the gate lines S1 to Sn, the data lines ...

Abstract

A display device includes a display panel including pixels; and a timing controller to calculate a grayscale usage ratio of input data and to determine an automatic-current-limit rate based on the grayscale usage ratio, the automatic-current-limit rate representing a power saving rate.

Description

technical field [0001] Exemplary embodiments relate to display devices. More particularly, embodiments of the inventive concept relate to a display device with reduced power consumption and a method of driving the display device. Background technique [0002] The display device can display images based on the input data. The display device may reduce power consumption of the display device by calculating an on-pixel ratio (OPR) of input data and by converting (or reducing, scaling, downscaling) the input data based on the on-pixel ratio. For example, first power consumption corresponding to first input data having a relatively high on-pixel ratio is larger than second power consumption corresponding to second input data having a relatively low on-pixel ratio. Accordingly, the display device can reduce the first power consumption by reducing the first input data. [0003] The effect of reducing power consumption is improved by converting (or reducing) input data. However,...
