Abstract
The invention concerns an active TFT matrix for optical sensor comprising a substrate, a TFT transistor matrix formed on said substrate, a set of transistor control lines ( ): a conductor level ( ) according to a specific pattern forming an electrode array ( ), each electrode ( ) defining a zone called pixel: a set of columns ( ) for load transfer between the electrodes ( ) and an external electronics. The pixel electrode ( ) is located entirely inside an outline delimited by two lines ( ) and two successive columns ( ), a protective gap (g , g ) being provided between the inside edge of said outline and the periphery of the pixel ( ) such that the pixel electrode ( ) does not cover either the lines ( ) or the columns ( ).
