Where to Start?

It is helpful to prioritize the single most important feature for your display. Is the resolution key in delivering the information that you are trying to portray? Is the device meant to be used outdoors? Is the shape of the display non-negotiable? The good news is that you don’t have to compromise to only one feature. Our Display Engineer’s specialty is to create the right display, whether it is a standard product or a display designed just for you.

Not every display is created equal. Each display technology has its own benefits and disadvantages, so depending on the features that are most important to you we can deliver the best technology.

The table below compares the different features for each display technology that we recommend for wearable applications. It compares AMOLED (Active Matrix Organic Light-Emitting Diode), PMOLED (Passive Matrix Organic Light-Emitting Diode), TFT LCD (Thin-film transistor liquid crystal display) and E-Paper.
