BenQ-Siemens EF51 Display and Interface

Display and Interface

With a 2.2-inch TFT display capable of showing 256K colors, the EF51 provides a simple interface typical of its time. The resolution of 120 x 128 pixels (~80 ppi density) is modest by today's standards but was adequate for basic tasks such as text messaging and simple phonebook navigation. The screen-to-body ratio of approximately 35.7% emphasizes the phone's small display, common for handsets from this era.
