Display interface block diagram
below shows how the display related signals are routed. Hurricane
display HWA controlling is done via LoSSI bus and pixel data is transferred via ViSSI-12 bus. MeSSI-8 is the
interface between Hurricane display HWA and Falcon OLED display.
As Falcon is self-emissive AM OLED display, no LED driver based backlighting is needed. An external DC-DC
convertor TPS65136 is used for the display powering.
Supply voltages for Falcon display:
1 VIO from the baseband SMPS (1.8V )
2 VBAT from Battery(3.7V)
3 ELVDD supply from external DC/DC converter TPS65136 (+4.6V)
4 ELVSS supply from external DC/DC converter TPS65136 (-4.9V)
EL_ON signal from Falcon display is enable for the DC/DC converter TPS65136.
