A light-emitting device display comprising a first light-emitting device and a second light emitting device is provided. The first light-emitting device and the second light-emitting device have a first forward voltage and a second forward voltage respectively, and the second forward voltage is higher than the first forward voltage. A first scan voltage and a second scan voltage is respectively provided to the first light-emitting device and the second light-emitting device. The first scan voltage is switched between a first scan-on voltage and a first scan-off voltage. The second scan voltage is switched between a second scan-on voltage and a second scan-off voltage. An absolute value of a difference between the second scan-on voltage and the second scan-off voltage is greater than an absolute value of a difference between the first scan-on voltage and the first scan-off voltage.
