Title

Liquid Crystal Droplet Array For Non-Contact Electro-Optic Inspections

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 μm thick polymer cavity and 130 μm air gap, LC droplet surface reshaping is clearly observed as the applied voltage exceeds 40 Vrms. Potential application of such a LC droplet array for inspecting the defected thin-film-transistor pixels is emphasized. © 2010 IOP Publishing Ltd.
