摘要

PROBLEM TO BE SOLVED: To solve such a trouble that a display is made with a gradation lower than a desired one when a self-luminous display unit migrates from a low-gradation display to a high-gradation display.

SOLUTION: A driving method of self-luminous type display unit comprises steps of: applying to each pixel circuit a gradation current matching a display gradation during a first period; applying to the above self-luminous element a display current based on the above gradation current during a second period subsequent to the first period to display the above matching display gradation; and applying a pre-charge current to the above self-luminous element during a third period prior to the first period.
