Benefits of technology

[0025]According to the embodiments of the present disclosure, it is possible to provide a display device that may decrease a settling time of a data voltage and power consumption without increasing a constant current of a data driving circuit.
[0026]According to the embodiments of the present disclosure, it is possible to provide a display device, a data driving circuit, and a data driving method that may decrease a settling time of a data voltage and power consumption by applying an offset value to the data voltage.

Problems solved by technology

However, when a bias setting value is adjusted to decrease a settling time of a data voltage which is supplied to the display panel and to increase a slew rate, there is a problem in that a constant current flowing in the driving amplifier of the data driving circuit increases and thus power consumption in the display device as a whole increases.

Abstract

A display device includes a display panel in which a plurality of subpixels are arranged at positions at which a plurality of data lines and a plurality of gate lines overlap with each other. A gate driving circuit drives the plurality of subpixels via the plurality of gate lines. A data driving circuit supplies a data output signal to the plurality of subpixels via the plurality of data lines, and the data output signal includes a data voltage and an offset data voltage which is generated by adding an offset to the data voltage. A timing controller controls the gate driving circuit and the data driving circuit.
