Display
The KRZR K1 featured a primary TFT display with 256K colors, spanning 1.9 inches. Though small by today's standards, the screen was adequate for basic tasks like viewing contacts and messages. Its resolution of 176 x 220 pixels at approximately 148 pixels per inch provided decent clarity for its era. Additionally, the phone included a secondary external CSTN display offering 256K colors and a 96 x 80 pixel resolution for quick viewing of notifications, time, and caller ID without opening the phone.
