Description
Technical field
A kind of touch panel, especially a kind of touch surface that can reduce parasitic capacitance.
Background technique
When touch device is set on panel of LCD, because being to constitute capacitor using ITO conductor plated film on panel, because
Liquid crystal display can carry out perforation without image of Buddha printed circuit board in plated film, therefore can plate one layer of dielectric again or spread one
Second layer conductor is plated after insulating medium layer again.
It intermeshes because array type capacity certainly will have conducting wire, therefore alternating share is easy to constitute quite high parasitic electricity
Hold, this parasitic capacitance is easy to influence touch control characteristics, therefore how to reduce parasitic capacitance, is the one of the sensitivity of promotion touch panel
Item important topic.
