This is a 1.44 inch display with a 128(RGB)x128 resolution. It's an IPS full viewing angle LCD display panel, so colors look great in any direction. The driver IC is ST7735S, which adopts a general 8-pin SPI interface.

TFT-LCD liquid crystal display is a thin film transistor liquid crystal display, and it is also true color. TFT liquid crystal provides a semiconductor switch for each pixel, and a point pulse can directly control each pixel, so each node is relatively independent and can be controlled continuously, which not only improves the response speed of the display screen but also can be accurately controlled. Display color level, make TFT LCD color more real, good brightness, high contrast, a strong sense of layering, and bright colors.
