Display
The NEC e636 featured a 2.2-inch TFT display, capable of rendering 256K colors. Despite its small screen-to-body ratio of approximately 30.6%, the screen resolution of 240 x 320 pixels provided a decent visual experience for basic tasks. This display size, while diminutive by today's standards, was more than adequate for the phone's primary functions, such as messaging and basic browsing. Coupled with a secondary monochrome OLED display, the phone offered basic notification functionality without needing to activate the main screen.
