Latest automotive project information
• For the resistive touch panel ,the project information as bellow:
Principle of C Type Touch Panel
• Cp : the parasitic capacitance
• Cs: Detected capacitance
• Cf: Induction capacitance by finger
• Without finger touch, Cs=Cp
• With finger touch, Cs= Cp + Cf
Normally ITO glass material is used due to reliability requirement in automotive
4 Kinds of C Type Touch Panel Structures (1)
1、 Single side ITO layer without bridge
Simple and usually used in the touch key option
2、 Single side ITO layer with bridge structure
Special technique to etch X/Y direction ITO pattern, one direction connect by ITO layer and another one is connect by metal of bridge.
Features:
Complex process
Higher cost
Poorer anti-ESD than no-bridge
Diamond pattern of ITO shadow
4 Kinds of C Type Touch Panel Structures (2)
3、 Double sided ITO layer for single ITO glass
Better anti- ESD, lower cost than the bridge, higher sensitivity
4、 Double ITO glasses
Better anti-ESD, optional ITO shielding layer, additional cover lens unnecessary, simpler process
CTP project information
• For the automotive, most of customer are in the developing phase, truly have design two projects as bellow:
CCM
Applications1 Scene viewing
Provide a driver with visual information about the environment
2 Scene understanding
Systems capture information to assist the driver
