Film-Film Touch Panels
Gunze Film-Film technology produces reliable, durable LCD integrated touch panels.
Film-Film (F-F) construction As a leader in the touch panel industry, Gunze F-F technology has now
produced highly durable, very thin touch panels that can even be used with pen input. A transparent conductive layer
(resistive layer) on the film uses polarizer-type reflection reduction to achieve high visibility, thinness, and low
parallactic difference.
Figures 1and 2 show a simplified model of the integration of a nematic (TN) LC cell with a touch input component.
