When selecting a 3.5 inch TFT LCD touchscreen display module in 2025, consider the following factors:
Higher resolution like 480x320 pixels provides sharper images and better detail compared to 320x240. Color depth (usually 16-bit or 18-bit) affects the richness of colors.
- Resistive Touchscreens: Work with stylus or finger pressure, generally cheaper, but less sensitive and no multi-touch.
- Capacitive Touchscreens: Support multi-touch gestures, more responsive and durable, but usually costlier.
Check if the module supports the interface your microcontroller or development board uses, such as SPI, 8/16-bit parallel, or RGB interface.
IPS panels provide better viewing angles and color consistency. High brightness (over 600 nits) is important for outdoor or brightly lit environments.
Popular driver ICs like ILI9488, ILI9486, and HX8357 have better community and library support, easing development.

The best 3.5 inch TFT LCD touchscreen display modules in 2025 combine high resolution, vivid color reproduction, responsive touch technology, and broad compatibility with popular microcontrollers. Whether you prioritize multi-touch capacitive screens for advanced applications or cost-effective resistive touchscreens for simple projects, there is a suitable module available. Modules like the Newhaven Display IPS capacitive touchscreen excel in outdoor readability and multi-touch, while the HiLetgo and Sanpyl modules offer excellent value for Arduino and Raspberry Pi enthusiasts. When choosing your display, consider resolution, touch technology, interface compatibility, and environment to ensure the best fit for your project.
Resistive touchscreens detect pressure from a finger or stylus and usually support single-touch input, making them cost-effective but less sensitive. Capacitive touchscreens detect changes in electrical charge, support multi-touch gestures, and provide more responsive and durable touch input, but are generally more expensive.
Yes, many 3.5 inch TFT LCD touchscreen modules are designed to be compatible with Arduino boards like the UNO and Mega. They often come with libraries such as MCUFRIEND_kbv or Adafruit GFX to facilitate programming and touch input handling.
Common resolutions include 320x240 pixels and 480x320 pixels. The higher 480x320 resolution offers better image clarity and is preferred for applications requiring detailed graphics.
Some models, especially those with IPS panels and high brightness LED backlights (around 900 nits), like the Newhaven Display module, are designed to be sunlight readable and maintain visibility in bright outdoor conditions.
Typically, these modules connect via SPI or parallel interfaces. Many come with drivers and support for Raspberry Pi OS variants. Installation involves wiring the display, installing the necessary drivers, calibrating the touchscreen, and configuring the system to recognize touch input.
