EMI Solutions for PCAP Display

Professional Electromagnetic Interference Protection by DINGTouch

In critical applications such as medical, military, aerospace, and industrial automation, the stability of displays and touchscreens directly impacts system safety and performance. Electromagnetic Interference (EMI) is one of the key factors that compromise display reliability, often causing screen flicker, distortion, static noise, or even touchscreen failure.

PCAP touchscreen are particularly sensitive to EMI. Since they rely on detecting variations in the electromagnetic field to recognize touch input, any interference can disrupt the signal, resulting in false touches or unresponsiveness. The close proximity of the LCD and PCAP layers makes them even more prone to mutual interference.

DINGTouch EMI Solutions

We provide a range of advanced EMI shielding technologies to ensure stable display performance even in complex environments:

• Transparent Conductive Film Shielding
  Utilizing ITO and metal alloy coatings, these films offer low resistance (10–20 Ω/sq), high optical transmittance, and excellent EMI attenuation (10–30 dB). They are fully compatible with touch sensors, ensuring both display clarity and responsiveness.

• Conductive Mesh Technology
  Made of stainless steel or copper mesh, with ≥85% light transmittance and ≤0.25 Ω/sq surface resistance. Shielding effectiveness reaches up to 75dB @ 50Mhz, providing strong EMI protection while maintaining superior optical performance.

• Controller Software Optimization
  Tailored algorithms reduce interference from LCD, Wi-Fi, or RF devices. This approach enables fast EMI suppression without additional hardware, and can be updated remotely.

• Metal & Flexible Shielding Layers
  Aluminum, copper, or steel plates combined with flexible silicone particle layers reflect and absorb electromagnetic waves, enhancing overall module shielding.

• Conductive EMI Tapes
  Copper or nickel-based tapes seal display edges and gaps, creating a quick and cost-effective shielding solution ideal for precision display modules.
