Light emitting device, drive control method thereof, and electronic device

A drive control method for a light emitting device, wherein the light emitting device comprises (a) at least one data line, (b) at least one pixel connected to the data line, (c) a common electrode, (d) a data driver applying a first voltage to the data line, and (e) an ammeter connected to the common electrode at one end,

• wherein the pixel comprises a pixel drive circuit and a light emitting element, in which (a) the pixel drive circuit including a first transistor electrically connected to (i) the data line and (ii) one end of the light emitting element, and (b) the other end of the light emitting element being connected to the common electrode;
• and comprising the steps of:
• applying a first set voltage as the first voltage to the data line from the data driver, wherein the first set voltage has such a potential that applies a forward bias voltage between both ends of the light emitting element via the first transistor;
• and
• measuring the current value of a detection current flowing from the data driver to the ammeter via the data line, pixel drive circuit and light emitting element of the pixel, and common electrode by the ammeter.
