Claims (4)
表示階調に応じて前記発光素子の駆動信号の信号値とデューティーとを決定する決定工程と、前記信号値と前記デューティーとが決定された前記駆動信号を前記発光素子に印加する印加工程とを含み、
前記決定工程は、表示階調が低くなるに従って、前記信号値を大きく、デューティーを小さくすることを特徴とする発光表示パネルの駆動方法。 In a driving method of a light emitting display panel having a pixel including a plurality of light emitting elements,
A determination step of determining a signal value and the duty of the drive signal of the light emitting device in accordance with the display gradation, and applying step of applying the drive signal to the duty and is determined to the signal value to said light emitting element Including
The method of driving a light emitting display panel, wherein the determining step increases the signal value and decreases the duty as the display gradation becomes lower .
