Ghost Touches on Capacitive Screens: Causes and Fixes
Fix capacitive ghost touches by testing power noise, grounding, chargers, water, display coupling, FPC routing, thresholds, baselines, ESD, and firmware.
Welcome to the TFT Display Technology Blog
This site is dedicated to exploring the science, engineering, and integration of TFT LCD displays across a wide range of embedded applications. From foundational display knowledge (What is TFT LCD) to advanced interface and bonding techniques, our goal is to help developers, engineers, and product teams make informed decisions when selecting and implementing display modules.
What You’ll Find Here:
- Fundamentals – Learn the basics of TFT LCD technology, panel types (TN vs IPS vs VA), resolution, brightness, and contrast (Resolution & Aspect Ratio).
- Circuit & Interface Design – Understand how to design backlight driver circuits, lay out FPCs, and choose between MIPI, LVDS, or RGB interfaces.
- Touch Integration – Discover best practices for capacitive touch panels (CTP), OCA bonding, and interactive controls with LED feedback.
- Calibration & Testing – Explore brightness tuning, color temperature adjustment, and EMI testing for industrial environments.
Whether you're developing an industrial HMI, a smart thermostat, or a handheld embedded device, this blog provides practical display knowledge tailored to real-world engineering needs.
