Abstract
A display device includes a display panel including a plurality of pixels, a data driver configured to apply a plurality of data voltages generated based on input image data to the pixels, an initialization voltage generator configured to generate an initialization voltage that initializes a light emitting element included in each of the pixels, a timing controller configured to generate a constant current control signal based on a load of the input image data, and a constant current generator configured to generate and transmit a constant current to the initialization voltage generator in response to the constant current control signal. As a result, the display device may reduce ripple of an initialization voltage by adjusting the initialization voltage according to a load of input image data, and a display device having a desirable signal-to-noise ratio (SNR) characteristic of a sensing operation may be provided.
