Display
The OT-255 is equipped with a modest 1.8-inch TFT display. With a resolution of 128 x 160 pixels and a pixel density of approximately 114 ppi, the screen quality is quite basic by modern standards. It supports 65K colors, which is adequate for the simple icon-based interface but leaves much to be desired for any multimedia content beyond basic visuals. The screen-to-body ratio is around 17.5%, meaning the display occupies a small portion of the phone's front, consistent with its focus as a communication device.
