Display
The C510 features a CSTN display capable of showing 65K colors at a modest resolution of 128 x 160 pixels. Considering the 1.67-inch screen size, this results in a pixel density of about 123 ppi, which, while not sharp by today's standards, was typical for its time. The external monochrome display with 96 x 96 pixels complemented the main screen, providing quick access to essential information such as time and notifications.
