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.
