Information input apparatus having functions of both touch panel and digitizer, and driving method thereof
First Claim
1. An information input apparatus having both functions of a touch panel and a digitizer comprising:
- a stylus pen for applying a power source and for touching;
a panel having upper and lower substrates, a first resistive layer formed on said upper substrate, a second resistive layer formed on said lower substrate, and a spacer for maintaining a predetermined distance and for providing insulation between said first and second resistive layers; and
mode selection means connected to said panel for selectively switching between ground and a power source for contact with said second resistive layer, to thereby select an operation mode for operating said panel as a touch panel or digitizer.
