Display
Equipped with a 2.0-inch TFT display capable of showing 16 million colors, the Nokia E51 offers clear and vibrant visuals for basic phone applications. Although small by today's standards, its 240 x 320 pixel resolution provides a decent viewing experience for the time, with a pixel density of approximately 200 ppi. The screen is a mere fraction of the body, indicating that during this era, the emphasis was more on tactile keyboard input rather than touch interaction.
