High-voltage driver LSI for passive matrix driven electronic paper with 160 tri-level voltage outputs

We have succeeded in developing a custom LSI with 160-outputs which supply tri-level voltages as high as 110 V using LDMOS technology for driving a passive-matrix driven electronic paper. The level shifter was designed to suppress the power consumption by employing the new level shifter which needed no DC bias voltage. The LSI chip was thinned to 35 μm for direct-mounting onto a flexible display.
