Abstract

The present invention relates to an integrated substrate and display with electromagnetic sensor loop, and particularly relates to a TFT/CF array substrate and flat display with electromagnetic sensor loop. In the present invention, electromagnetic sensor loop is formed on one substrate of a display panel for getting the integrated substrate with electromagnetic sensor loop. The integrated substrate with antenna loop has both a function of a detecting board and a function of one substrate of the display panel, for example a function of a TFT/CF array substrate. Therefore, a display panel or a display having electromagnetic inputting function can be fabricated by the integrated substrate without additional detecting board and digitizer tablet
