In the case of the IPCT (Improved Projected Capacitive Touch Panel), EVERVISION apply single-sided coated ITO lenses, which can also be used in the MONO LC display production. The IPCT has a tough surface hardness of 7H, reliably detects up to 10 fingers at the same time and is neither sensitive to cleaning nor to disinfecting agents. Its transparency is 85 percent. It has an I²C or USB interface and a chip-on-flex structure. The IPCT touch can be operated both with the finger and with thin gloves.
Stand-alone IPCT
EVERVISION Electronics Europe offers standard or full customized IPCT from 3.5 "up to 17.0". IPCT’s are available as stand-alone component or attached to corresponding EVERVISION TFT displays. Technically up-to-date, the IPCT scores high against conventional PCT solutions, especially in economical aspects. EVERVISION can offer a long-term availability at favorable conditions and also realize small minimum order quantities of 120 pieces.
IPCT solutions with cover glasses
On demand can be the IPCT also fitted with a cover glass. Cover glasses are custom-made and can be designed up to a material thickness of 3mm. Special mechanical processing such as corner rounding and cut-out, printing and surface refinement for anti-glare, anti-reflective and anti-fingerprint are also possible.
The evaluation tool for optimizing the touch controller Parameters
To apply a cover glass to the IPCT or to use special gloves, the touch controller settings have to be adjusted. In 2014, EVERVISION developed an evaluation tool for the parameterisation of its own IPCT. The user can even define the ideal controller settings and integrate them into his application. The software is quickly installed on the computer and communicates with the IPCT via USB bridge board.
It is possible to change the settings of up to 12 parameters different from the default settings. The self-explanatory tool menu is easy to handle and the monitor can display up to 10 touch points. These are presented in different colors and allow a safe assessment of the quality of the touch detection.
