This family consists of 2 compatible variations (only the depth is different due to backlights) to give a possible high and low end products.
R190E1-L01: with an excellent brightness of 600 cd/m2 and a 176 Degree all-round viewing angle aimed at high end applications that wish to differentiate themselves from the competition.
R190E3-L01: the standard variation with a brightness of 280 cd/m² but also with 176 Degree all-round viewing angle.
The inverter is integrated into both modules to aid optimisation of brightness and lifetime, as well as creating a simpler design in cycle.
Both products are guaranteed in writing for 5 years which is critical for some mechanical designs.
