Method for actuating display device

A method for driving a display device,

• the display device comprising:
• a pixel comprising a light-emitting element and a transistor;
• a frame memory;
• an arithmetic circuitry electrically connected to the frame memory;
• and
• a monitor circuit comprising a monitoring transistor and a monitoring light-emitting element,
• the method comprising the steps of:
• supplying a first observation signal, a second observation signal, a third observation signal, and a fourth observation signal to the arithmetic circuitry;
• updating a forecast error parameter in the arithmetic circuitry by using the first observation signal, the second observation signal, the third observation signal, and the fourth observation signal in accordance with a regression model;
• updating an output parameter in the arithmetic circuitry by using the forecast error parameter in accordance with the regression model;
• generating a second image signal in the arithmetic circuitry from a first image signal supplied from the frame memory by using the output parameter;
• and
• supplying the second image signal to the pixel,
• wherein the regression model is a Kalman filter,
• wherein the first observation signal is a third image signal supplied from the frame memory,
• wherein the second observation signal is a first value of current flowing through one of the light-emitting element and the transistor or a first value of voltage converted from the first value of current,
• wherein the third observation signal is a second value of current flowing through the monitoring transistor or a second value of voltage converted from the second value of current, and
• wherein the fourth observation signal is a third value of current flowing through the monitoring light-emitting element or a third value of voltage converted from the third value of current.
