METHOD FOR DETERMINING DUTY RATIO OF DRIVING OF LIGHT EMITTING DEVICE AND DRIVING METHOD USING SAME DUTY RATIO

摘要

PROBLEM TO BE SOLVED: To provide a determining method for the duty ratio of driving of a light emitting device which can improve reliability by suppressing deterioration of a light emitting element and a driving method using the duty ratio.

SOLUTION: Disclosed is the determining method for the duty ratio of the light emitting device which makes display with an analog video signal and the method is characterized in that the range of the duty ratio at which luminance which is a little larger than 0.8 time as large as a maximum value is obtained is determined as an optimum range as to the characteristic obtained by integrating a characteristic of luminance an X hours later which is value of current density and a characteristic of luminance the X time later for the duty ratio when the total quantity of electricity flowing to the light emitting element in one frame period is specified.
