Display
The display on the NIU GO 21 is another nod to basic functionality. It sports a 1.8-inch TFT screen capable of displaying 65K colors. With a resolution of 128 x 160 pixels and a pixel density of approximately 114 pixels per inch, the screen quality is decent for text and simple graphics but is not designed for detailed visuals or high-resolution images. The display occupies about 21.6% of the phone’s body, making it clear that the design prioritizes durability and ergonomics over screen real estate.
