Abstract
We report a high density liquid crystal (LC) droplet array for non-contact inspection. The incident light is modulated by changing the shape of each droplet using a dielectric force even though the electrode and droplet array are separated by a fairly large air gap. The reshaped LC droplets cause colour change which is easily inspected by the human eye. In a sample with 30 mu m thick polymer cavity and 130 mu m air gap, LC droplet surface reshaping is clearly observed as the applied voltage exceeds 40 V(rms). Potential application of such a LC droplet array for inspecting the defected thin-film-transistor pixels is emphasized.
