Patent ID: 7292234

Claim:
An organic EL panel drive circuit for current-driving an organic EL panel through terminal pins thereof, which are provided correspondingly to R, G and B display colors, comprising: at least three first switch circuits provided correspondingly to said terminal pins for R, G and B display colors and connected between said terminal pins and a first potential line at a first potential, for discharging residual chargers of organic EL elements having anodes connected to said terminal pins; at least three second switch circuits provided correspondingly to said terminal pins for R, G and B display colors and connected between said terminals and a second potential line at a second potential, for setting said anodes of said organic EL elements to predetermined potentials lower than light emission potentials of said EL elements; and a pulse generator circuit for generating pulses for turning said first switch circuits ON and then turning the first switch circuits OFF and then turning the second switch circuits ON during a precharge period within a predetermined time period, respectively.
