DISPLAY DEVICE

摘要

A display device includes: a first sub-pixel and a second sub-pixel, wherein the first sub-pixel includes: a first light emitting diode coupled between a first node and a second node; a first transistor configured to turn off the first light emitting diode by lowering a voltage of the first node below a voltage of the second node by providing a first initialization voltage to the first node; and a second transistor configured to turn on the first light emitting diode by increasing the voltage of the first node above the voltage of the second node by providing a first driving current to the first node, wherein the second sub-pixel includes a second light emitting diode, wherein a capacitance of the first light emitting diode is higher than a capacitance of the second light emitting diode.
