Title:
TRANSPARENT CONDUCTIVE FILM ROLL AND PRODUCTION METHOD THEREOF, TOUCH PANEL USING IT, AND NON−CONTACT SURFACE RESISTANCE MEASURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2003/001539
Kind Code:
A1
Abstract:
A transparent conductive film roll which has a transparent conductive film on at least one surface thereof, and which is suitable for, especially, a large panel due to the excellent distribution uniformity of surface resistance in longitudinal and lateral directions, wherein the distribution uniformity D of surface resistance defined by the following expression (1) is up to 0.2 when the surface resistance of the transparent conductive film is measured at a total of 33 points within the film roll. D= (Rmax − Rmin)&sol (Rmax &plus Rmin) ... (1), where Rmax denotes a maximum value and Rmin a minimum value among 33−poing surface resistance measurements.
