The thin film transistor is formed on an insulating substrate. A first main electrode of the thin film transistor is connected to an output terminal and a control electrode of the thin film transistor receives a control signal. The thin film transistor includes a non-monocrystal semiconductor. The capacitor has a first electrode connected to a second main electrode of the thin film transistor and a second electrode receiving a variable voltage. The diode is electrically connected between the second main electrode of the thin film transistor, the first electrode of the capacitor, and a power terminal in series. The diode includes a mono-crystal semiconductor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"DC/DC converter and liquid crystal display","description":"A DC/DC converter of a liquid crystal display includes a charge pump having a thin film transistor, a capacitor and a diode.
