Electronic device for driving tunable device

An electronic device, comprising:

• a tunable component, electrically connected to a circuit node;
• a first source follower circuit, electrically connected to the circuit node;
• a scan transistor, electrically connected to the circuit node, wherein the scan transistor is further electrically connected to a data line, wherein the scan transistor provides a data voltage to the circuit node from the data line;
• a first compensation transistor, electrically connected to the first source follower circuit;
• and
• a first bias transistor, electrically connected to the first terminal of the first source follower circuit and a first operation voltage,
• wherein a first terminal of the first compensation transistor is electrically connected to a first terminal of the first source follower circuit, and a second terminal of the first compensation transistor is electrically connected to a control terminal of the first source follower circuit,
• wherein a control terminal of the scan transistor and a control terminal of the first compensation transistor receive a scan signal,
• wherein during a scan period, the scan transistor and the first compensation transistor are turned-on, and the first bias transistor is turned-off.
