Expressive LCD Eyes

Two round GC9A01 LCD screens display smooth, animated eyes. Choose from 9 built-in eye styles or design your own custom eyes with our free Eye Creator Tool and load them from MicroSD card.

Crystal Clear with Lenses

Our eye displays are fused with precision-cut lenses using optically transparent adhesive. The result is a seamless, glass-like finish that looks stunning in any light — no visible LCD edges, no air gaps. See the dramatic difference for yourself.
