Detailed Analysis of Display Features
Display Technology: Transmissive a-TFT
The module employs a transmissive a-TFT (active matrix thin-film transistor) technology, which ensures high-quality visual output even in ambient lighting conditions. This technology enables each pixel to be controlled individually, enhancing the display’s brightness, clarity, and color contrast. The transmissive nature of the display allows for the backlight to shine through, providing better visibility in well-lit environments.
Resolution and Graphics Quality
With a resolution of 128×128 pixels, the display offers a sharp and clear view of graphics, text, and other images. This resolution is particularly well-suited for devices where space and clarity are paramount, such as handheld gadgets, wearables, or portable tools. The RGB color format ensures vibrant colors and is ideal for presenting graphical user interfaces (GUIs), icons, and even simple images.
Integration and Connectivity
Interface and Communication Protocol
The 1.44″ TFT LCD display uses a SPI-4 wire interface for communication. This standard protocol makes the module compatible with a wide range of microcontrollers, including popular options like Arduino and Raspberry Pi.
