Display Characteristics
Equipped with a 1.8-inch CSTN display that supports 65K colors, the WX390 offers a basic visual experience with a resolution of 128 x 160 pixels. The screen-to-body ratio of roughly 21.6% signifies a relatively small display area, which is consistent with the design considerations of the time, focusing more on functionality than expansive screen space. The pixel density of approximately 114 ppi is low by modern standards, resulting in a less sharp display, but this should suffice for simple tasks such as viewing text messages and basic phone navigation.
