Display and User Interface
The 2.4-inch TFT resistive touchscreen boasted a resolution of 320 x 320 pixels, providing clear and vibrant colors, though limited to 65K—standard for the time. Despite occupying around 27.9% of the screen-to-body ratio, the display was adequate for viewing emails, basic web pages, and multimedia, thanks to its crisp pixel density of ~189 ppi. This focus on optical clarity highlighted the Treo 650’s role in promoting productivity on-the-go, a hallmark of Palm OS devices.
