### **LCD Screens – An Overview** #### **1. What is an LCD?** LCD stands for **Liquid Crystal Display**. It is a type of flat-panel display technology that uses liquid crystals to produce images. LCDs are widely used in TVs, computer monitors, smartphones, and embedded systems like Arduino projects. --- #### **2. How LCD Works?** LCDs function by manipulating light using liquid crystals. The key components include: - **Backlight:** Provides illumination (LEDs are commonly used). - **Liquid Crystal Layer:** Controls how light passes through. - **Polarizing Filters:** Help control brightness and contrast. - **TFT (Thin-Film Transistor):** Used in modern LCDs for better image quality. When electricity is applied to the liquid crystals, they align in a way that either allows or blocks light, creating images. --- #### **3. Types of LCD Displays** 1️⃣ **TN ...
