▎ 摘 要
NOVELTY - The screen has a base plate located between a first graphene transparent conductive film layer and a second graphene transparent conductive film layer. The first graphene transparent conductive film layer is divided into multiple longitudinal sensing zones. The second graphene transparent conductive film layer is divided into multiple horizontal sensing areas. A main control chip is connected with a capacitive sensing circuit. A digital signal processor is connected with an analog-to-digital converter for receiving digital signal to calculate touch coordinate pressure. USE - High-sensitivity graphene capacitive touch screen. ADVANTAGE - The screen has stable structure, and realizes dual-induction touch and pressure sensitive function with high sensitivity. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a high-sensitivity graphene capacitive touch screen. '(Drawing includes non-English language text)'
