A display apparatus may include a first drive circuit configured to output a driving signal, the driving signal including a first period during which the driving signal has a first value, a second period during which the driving signal has a second value different from the first value, and a third period during which the driving signal has a third value between the first value and the second value; a second drive circuit configured to receive the driving signal and generate a gate signal based on the driving signal; and a display panel including a light emitting device that is configured to emit light based on the gate signal, wherein a length of at least one of the first period, the second period, or the third period is adjustable based on a temperature associated with the display apparatus.

Display device, data driver and timing controller

Embodiments of the present disclosure relate to a display device, comprising: a display panel in which a plurality of driving voltage feedback lines branched from a driving voltage line for supplying a driving voltage to a plurality of subpixels are disposed; a driving circuit for supplying a data voltage to the plurality of subpixels and determining a deviation of a feedback driving voltage detected through the plurality of driving voltage feedback lines; and a timing controller for compensating for image data depending on positions at which the plurality of driving voltage feedback lines are branched in the display panel based on the deviation of the feedback driving voltage, and supplying a compensated image data to the driving circuit.
