Display
The Samsung B510 is equipped with a CSTN display capable of showing 65,000 colors. This 1.77-inch screen has a modest resolution of 128 x 160 pixels, which results in a pixel density of approximately 116 ppi. While the display size and quality might seem limited by today's standards, it was suitable for the basic tasks users performed over a decade ago. Its screen-to-body ratio of 22.3% reflects the design philosophy of maximizing keyboard space over display area, which was typical for phones that focused on usability for calling and messaging.
