ডিসপ্লেতে TFT আবার কি!

Most brands mention all the display specs—resolution, brightness, refresh rate—but they rarely reveal what kind of TFT (Thin Film Transistor) technology is used. Why? Because that’s where the real quality difference lies.
In this video, I explain:
✅ What is TFT technology?
✅ What is the difference between a-Si TFT and Oxide TFT?
✅ Why does Oxide TFT provide better performance, brightness, and color accuracy?
📌 Oxide TFT (Indium Gallium Zinc Oxide) offers 10–50x higher electron mobility than traditional a-Si TFT, resulting in:
Brighter panels
Higher refresh rates
Better support for high-resolution displays
