Less surface resistance
New conductive polymers from the Clevios family from Heraeus reduce the sheet resistance on flexible and foldable touchscreens by more than 50 percent and thus improve the conductivity and transmission of the wafer-thin display layers, according to the manufacturer. Clevios HY E is therefore set to become a key material for manufacturing the next generation of foldable displays and smartphones with sufficient stability and reliability.
Clevios HY E is an improved hybrid product made from silver nanowires and the conductive polymer PEDOT:PSS. According to the company, a conductive layer with a bending radius of one millimeter can withstand more than 300,000 bends at 40Ω/sq without damage. In addition, the optical properties of LC displays are improved: the polymer enables scratch-resistant protective layers on the display glass and reduces disturbing light reflections by over 50 percent compared to previously used ITO layers (indium tin oxide), which increases the optical display contrast. The product has a lower inherent color and higher transmission than ITO and can also be applied using a very cost-effective wet coating process. sw
