Hi Esteban,
Usually the used pattern is vendor,ddic+panel-model
novatek,nt37703-motorola-bronco
...but motorola bronco isn't the model of the panel.
My recommendation - look at some video of screen replacement, stop at moment
when FLEX cable from panel is visible and that's where the panel model usually is.
