Abstract

A reference current generating circuit is proposed for currentmode displays using plural column driver ICs. The circuit supplies the uniform current with the column drivers. The cascaded circuits use an input reference current, sense it, and independently generate output currents in accordance with the current. The variation of generated output current in the reference current generating circuit of each column driver IC is reduced as compared with the conventional method. The generated output currents in column drivers have 0.1% error to the input reference current.
