system with 2x3 white LEDs connected in series.

The display has the following on-chip features: contrast control, DC/DC converter, temperature

compensation and N-line inversion for low cross talk CMOS compatible inputs/outputs.

The complete display module includes LCD glass, flex cable (FPWB), driver IC and illumination

system.

Interface

The PDA display has two interfaces: 16 data lines parallel video RGB interface ViSSI and op-

tional 3-wire 9-bit serial interface LoSSI. Video interface is used for image data transfer (video
