Display
The phone boasts a 2.4-inch TFT display capable of showing 256K colors, with a resolution of 480 x 640 pixels. This screen specification translates to a remarkable density of approximately 333 pixels per inch, ensuring clarity and vibrant color representation—even on such a compact screen. The Sharp 904 also features a secondary external mono display, which simplifies checking notifications and time at a glance without activating the main screen, thus conserving battery life.
