Dcc X Ito Solution Rev.0.3

The document discusses DCC&ITO touch screen solutions, including: 1. The DCC touch screen technology uses capacitive sensing and allows for design flexibility without constraints of pad size or location. 2. Touch detection works by measuring changes in impedance between the touch pad and a finger. 3. ITO touch screens have high transmittance, thin thickness, and low surface resistance, making them suitable for use with DCC solutions. 4. A demo mobile phone uses a 5-key ITO and DCC solution that is lower cost than mechanical keys and allows for a larger LCD surface area.
