Abstract: The present disclosure provides a display device and a driving circuit. In the display device, a first subpixel is connected to a first data line and a first reference voltage line, and includes an emitting device and a driving transistor; and a second subpixel is connected to a second data line and a second reference voltage line, and includes an emitting device and a driving transistor. The driving time of the first subpixel includes a first initialization time in which a reference voltage is applied to the first reference voltage line and a first tracking time in which a voltage of the first reference voltage line increases from the reference voltage and then is saturated. Sensing times for subpixels having different channel sizes are reduced.
