FAQ
-
Q : What is high resolution for a small industrial LCD?
It depends on size. For graphic LCDs, the top of the COG range is high. For TFT, XGA and above is generally high.
-
Q : Is a higher resolution LCD always better?
No. Higher resolution adds cost, power use and controller load. Pick the lowest resolution that keeps your content sharp.
-
Q : How many touch points does PCAP support?
Many modules support up to 10 touch points. Check the controller datasheet for the exact number.
-
Q : Can the shape and size be changed?
Yes. Cover glass, outline, and printing can be adjusted to fit your product.
-
Q : Is PCAP more expensive than resistive?
Usually yes, per unit. Glass, a sensor grid, and a controller add cost. Many teams accept this for clearer images and better durability.
-
Q : Does water affect a PCAP screen?
It can. Water droplets may cause false touches. Controllers with water handling reduce the problem. Heavy water flow is still harder.
-
Q : Can a PCAP screen work with gloves?
Often yes. A controller with glove mode can read a gloved finger. Results depend on the glove, so test with the real glove.
-
Q : Is PCAP the same as PCT?
Yes. PCT stands for Projected Capacitive Technology. The terms are used for the same thing.
