Display
The JAQ4 featured a 2.8-inch TFT resistive touchscreen capable of displaying 65K colors, with a resolution of 320 x 240 pixels. The screen-to-body ratio was modest at approximately 27.4%, which might have made the display feel cramped for extensive web browsing or media consumption. Handwriting recognition was a notable feature, albeit not widely popular due to the limitations of resistive touchscreen technology. These specifications reflect a device more suited for basic applications and text-based tasks rather than multimedia-rich activities.
