ABSTRACT:
A digitizer screen and method of making. A coated conductive plastic film is perforated and is used in conjunction with a glass or other panel to provide a screen which may be used in an electronic digitizer for converting the position and movement of a stylus or other device on the screen to electrical signals representative of such positioning and movement. The perforated coated conductive plastic film may be laminated to the glass panel to form an integrated structure which does not require the use of masking and etching or similar processes to produce a desired apertured matrix pattern in the plastic film. Various arrangements of the plastic film are disclosed which facilitate the connection of the apertured portion of the plastic film to associated electronic components.
