Display
The display on the Siemens SP65 features a 2.1-inch TFT screen that supports 65K colors. Its resolution of 132 x 176 pixels provides basic clarity, sufficient for the simple user interface and functionality it was expected to deliver. This translates to a pixel density of approximately 105 ppi, which was quite common at the time. The screen size and quality might not astound by today’s standards, but the device was practical for the era it was released in.
