1. An electronic device, comprising:
a pixel circuit, comprising a driving transistor, an emission transistor, a capacitor and a light-emitting element;
wherein the driving transistor is electrically connected to the emission transistor and the capacitor; and the emission transistor is electrically connected to the light-emitting element;
wherein under the same driving voltage, the driving transistor has a first conductive resistance value, the emission transistor has a second conductive resistance value, and the first conductive resistance value is greater than the second conductive resistance value;
wherein the first conductive resistance value is calculated according to a current flowing through the light-emitting element and the first conductive resistance value is expressed by a following formula:
Ron1=0.0023*I_led6−0.1338*I_led5+3.1886*I_led4−39.162*I_led3+263.54*I_led2−952.84*I_led+1678.5
wherein Ron1 is the first conductive resistance value, I_led is a value of the current flowing through the light-emitting element, and I_led is less than or equal to 10 milliampere (mA).
