Display device and method for controlling light-emitting element by using memristor

A display driving device, comprising:

• a light emitting unit configured to include a light emitting element;
• a driving unit including a memristor and configured to drive the light emitting unit;
• and
• a switching unit including a switching thin-film transistor and configured to determine, depending on a scan voltage, whether to apply a data voltage to the driving unit,
• wherein the driving unit is configured to be connected to a first node branching to the light emitting unit and the switching unit,
• wherein the switching unit is configured to be connected to the first node, a gate line for receiving the scan voltage, and a data line for receiving the data voltage,
• wherein the light emitting unit is configured to be connected to the first node and a high-potential voltage supply line for receiving a higher-potential voltage, and
• wherein the data voltage is a set voltage for shifting a state of the memristor from a higher-resistance state to a lower-resistance state, or a reset voltage for shifting the state of the memristor from the lower-resistance state to the higher-resistance state.
