Zusammenfassung:A light-emitting device is provided. The light-emitting device includes a light-emitting element, a driving circuit and a compensation unit. The driving circuit is coupled to the light-emitting element. The driving circuit receives the first data signal to drive the light-emitting element and outputs the sensing signal. The compensation unit receives the sensing signal and compensates the first data signal. The compensation unit includes a first comparator circuit and a second comparator circuit. The first comparator circuit includes a first addition terminal, a first subtraction terminal, and a first output terminal. The second comparator circuit includes a second addition terminal and a second subtraction terminal. The first subtraction terminal receives the sensing signal. The first output terminal is coupled to the second summing terminal.
