Display
The A3100 sports a 2.8-inch TFT resistive touchscreen that supports 65K colors. The resolution of 240 x 320 pixels, resulting in a pixel density of about 143 ppi, is understated by today’s standards but was competitive over a decade ago. The small size and screen-to-body ratio of around 37% limit the device's visual experience, though it does offer basic functionality and handwriting recognition, catering to business users of its time.
