CPC G09G 3/3275 (2013.01) [G09G 2300/0439 (2013.01); G09G 2300/0842 (2013.01); G09G 2310/08 (2013.01); G09G 2320/0626 (2013.01)] | 14 Claims |
1. A display device, comprising:
a display panel comprising a plurality of subpixels; and
a data driving circuit configured to supply a data voltage to the plurality of subpixels,
wherein each of the plurality of subpixels comprises:
a light-emitting device,
a driving transistor configured to drive the light-emitting device, and
a storage capacitor electrically connected between a first node and a second node of the driving transistor,
wherein the data driving circuit is further configured to:
detect, in an external sensing period, a change value of a threshold voltage of the driving transistor comprised in at least one of the plurality of subpixels, and
supply, in a display period, to at least one subpixel of the plurality of subpixels:
the data voltage, obtained by adding a first voltage corresponding to a luminance of the light-emitting device, and
a second voltage smaller than the change value of the threshold voltage of the driving transistor,
wherein the second voltage is a value obtained by multiplying the change value of the threshold voltage of the driving transistor by a boosting loss ratio.
