Preliminary

64-Channel Organic EL Cathode Driver

1/11

GENERAL DESCRIPTION

The ML9371 is an organic EL cathode driver LSI with 64 outputs. Since this LSI has the output condition setting

function, which allows setting of all outputs High, all outputs Low, and all outputs High Impedance, the user can

set driving methods suited to the characteristics of individual organic EL panel. When combined with ML9361 the

organic EL anode driver, the ML9371 can drive a 64

× 128 full-dot panel.
