Organic el driving circuit and organic el display device

【Task】 In the case of gradation control a passive matrix type OEL element and a low voltage driving reducing power consumption is to provide a easy organic EL driving circuit or the organic EL display device to the brightness correction in the low luminance . In the case of a time-division gradation control a passive matrix type OEL element and a low voltage driving reducing power consumption, providing easy organic EL driving circuit and an organic EL display device to the brightness correction in the low luminance It lies in the fact. A The present invention, a period corresponding to the PWM pulse receives display data corresponding to the light emission luminance to generate a PWM pulse having a pulse width corresponding to the display data of the organic EL element, the register organic EL outputs a drive current in the organic EL driving circuit having a current drive circuit for driving the element has a peak current generating circuit for generating a peak current in the register drive current register current drive circuit, each output pin register organic EL element is connected each provided corresponding register peak current generating circuit, generates a large peak current than the current value of the driving current corresponding to the register display data when the value of the display data is the data value indicating low luminance less than a predetermined value it is intended to. .FIELD 1
