Abstract
A subpixel circuit, a display panel, and a display device are disclosed. A subpixel circuit for operating a subpixel of a display panel may include: a light emitting circuit including an light emitting element to receive a high-potential voltage, the light emitting circuit being configured to control the light emitting element according to a driving voltage and to output a control voltage; a reference circuit configured to receive the control voltage and a low-potential voltage and to control a driving current flowing through the light emitting element; an amplification circuit configured to compare the control voltage and a data voltage to generate the driving voltage for controlling the light emitting circuit; and an input circuit configured to receive the data voltage and a first scan signal and to control a timing of applying the data voltage to the amplification circuit based on the first scan signal.
