I don't see LCD layer here. Passive color filters, B/W capsules (which reflects or doesn't reflect incoming light, depends on orientation), TFT (thin layer transistors, not LCD — liquid crystal display!) as control to orient capsules.
Yes, it is not 4 color capsules as in Spectra, but where is LCD?
LCD what is caught my attention (and surprise) in your commentary.
Rather opposite: I never seen consumer products with two-layer displays.
