Display and Interface
The OT 511 sported a monochrome graphic display, with a resolution of 96 by 64 pixels. Despite being limited to black-and-white visuals, it was sufficient for the phone's basic functions, allowing for the display of text and simple animations. The screen could accommodate up to six lines of text, enhancing readability for SMS and basic navigation. The ability to download animations and melodies added a dash of personalization, which was quite an appealing feature at the time.
