After a characteristically thorough analysis about the pros and cons of LCD over the previously used LED, it was universally acknowledged that a Light Emitting Diode suits our purpose best.
All past and current Conzerv products are therefore equipped with an LED display panel over an LCD, and the resulting advantages can be clearly viewed below:
 
Given the same ambient lighting and other environmental conditions, the LED display has a far better visibility than an LCD, and can be viewed clearly even from across the room. The LED display also makes more sense considering that quite a few applications of the energy meter would require distant viewing.
Reinforcing our practical approach are these findings from the iLabs analytical team:
