However, because of the high threshold of projected capacitive touch IC , it would be difficult to complete it unless it has considerable R & D strength. Its main technical thresholds are (a) treatment of system noise, (b) overcoming of sweat, oil, paste, and dirt on fingers (c) the thickness of the cover lens or the protective surface of the mechanism reduces the induction sensitivity (d) caused by different physical constitution Reduced system stability(e) In small-size applications, the low resolution of the finger makes the cursor resolution difficult to improve , often making Demo easy and mass production difficult . Without the accumulation of long-term experience, the stability problem of mass production cannot be overcome. At present, only new American thinking (Synaptics) and Taiwan ? Up (Sentelic) in this regard the long-term basis , other manufacturers probably will need to spend a while learning curve.
