The KS20 featured a 2.8-inch TFT resistive touchscreen with a resolution of 240 x 320 pixels, translating to approximately 143 ppi pixel density. While the touchscreen was a novel feature at the time, it was resistive, meaning it required pressure to register input—a characteristic that ultimately did not stand up well against the capacitive screens in use today. One key advantage, however, was the inclusion of handwriting recognition, targeting business users or those who preferred more interactive input methods.
