Several other factors will indirectly influence the maximum brightness of a DGP projector. Many applications will have module size and input power limitations. Higher brightness projectors will require more input power. Some placements in the vehicle may limit the total power available to deliver to the module, limiting the maximum brightness of the projector. Higher power or larger LEDs will also increase brightness, but this will also typically increase the required thermal cooling solution. If this thermal solution makes the module size too large, the brightness may need to be reduced to accommodate the size constraint. If power or thermal constraints limit brightness, the size of the displayed image may need to be reduced in order to achieve desired brightenss targets.
