1. What is a TFT LCD?

TFT LCD (TFT liquid-crystal display) is a type of liquid-crystal display that uses thin-film transistor technology to improve image qualities such as addressability and contrast. A TFT LCD is an active matrix LCD, as opposed to a passive matrix LCD or a few simple, direct-driven (i.e., segments directly connected to electronics outside the LCD) LCDs. TFT LCDs are found in a variety of appliances such as televisions, computer monitors, mobile phones, handheld devices, video game systems, personal digital assistants, navigation systems, projectors, and automobile dashboards.

2. Is a TFT screen good for the eyes?

LCD: Liquid Crystal Display; an increasingly common type of display panel (like TV, PC computer, Mobile phone screen, etc.) TFT: Thin film transistor, which controls the color and brightness of the LCD's pixels, none directly endanger the eyes.

4. Is TFT better than LCD?

TFT displays motion more smoothly and responds more quickly than a monochrome LCD panel. TFT displays are bit expensive compared to monochrome LCD panels since they consume more electricity when operating.

5. Are TFT and LCD the same?

TFT is a type of LCD that uses thin film transistor technology to improve image quality, whereas an LCD is a type of display that uses the modulating properties of liquid crystals to form what we call an LCD (liquid crystals display), which does not directly emit light.

TFT stands for "Thin-Film-Transistor" and is a type of LCD that uses thin-film transistor technology to enhance features like contrast and responsiveness. Each pixel is powered by its own transistor which has faster response times.

TFT displays work by controlling individual pixels with electric fields and adjusting the polarization of liquid crystals to regulate how much backlight passes through. This allows for precise control of each pixel, earning TFT displays the name "active-matrix" technology.

Arduino TFT Display:

The Arduino backlit TFT LCD display includes a micro SD card slot and supports drawing text, images, and shapes using the TFT library. It works with any Arduino board but is designed to fit the Arduino Esplora and Robot. TFT technology delivers vibrant colors and sharp graphics for detailed visuals.

Display Size vs Resolution Comparison

Display Size	Typical Resolution	Best Use Cases
0.96″ – 1.44″	128×64, 128×128, 160×128	Sensor readouts, small IoT dashboards, compact wearables
1.8″ – 2.0″	160×128, 220×176	Minimal UIs, menu screens, handheld tools
2.2″ – 2.4″	240×320	Graphs, system status, basic touch interfaces (if touch-enabled)
2.8″ – 3.2″	240×320, 320×240	Richer GUIs, control panels, project enclosures
3.5″ – 5.0″	320×480, 480×320, 800×480	Advanced UIs, HMI panels, portable consoles
7.0″ and above	800×480, 1024×600, 1280×720+	Full dashboards, media displays, SBC monitoring screens

Tips for Calibration & Maintenance

Touchscreen Calibration (if touch-enabled): Run the provided calibration sketch or tool to correct touch coordinates. Save calibration data in code or config files.

Brightness & Power: Use PWM on the backlight pin (where supported) to reduce brightness and power consumption, especially for battery-powered projects.

Protect the Screen: Avoid pressing hard on the surface. Use a stylus for resistive touch panels, and consider a screen protector for frequent use.

Keep Connectors Secure: Ensure header pins, ribbon cables, and jumpers are firmly seated. Loose connections cause flickering or random resets.

Avoid Overvoltage: Many TFT modules expect 3.3 V logic. If you’re using a 5 V Arduino, confirm that the board includes level shifting or use an external level shifter.

Clean Gently: Use a soft, dry microfiber cloth to clean the display. Do not use strong solvents or excessive moisture.
