Understanding 7 Inch TFT Screens

What is a TFT Screen?

TFT (Thin-Film Transistor) screens are a type of LCD (Liquid Crystal Display) technology. They use transistors to individually control each pixel, resulting in sharper images and faster response times compared to older LCD technologies. A 7 inch TFT screen provides a compact display size suitable for various applications.

Key Features to Consider

When choosing a 7 inch TFT screen, several key features should be considered:

Resolution: Measured in pixels (e.g., 800x480, 1024x600), higher resolution means sharper images. Consider the application; higher resolution may be necessary for detailed images or text.
Brightness (cd/m2): Measures screen luminance. Higher brightness is better for outdoor use or bright environments.
Contrast Ratio: The difference between the darkest and brightest colors. A higher contrast ratio results in richer, more vibrant images.
Response Time: How quickly the screen changes from one color to another. Faster response times are ideal for videos and gaming.
Viewing Angle: The range of angles from which the screen can be viewed clearly. Wider viewing angles are more convenient for multiple viewers.
Interface: Common interfaces include LVDS, SPI, and parallel interfaces. Ensure compatibility with your device.
