Display
Featuring a dual-display configuration, the Z520 had a primary TFT screen with 65K colors, measuring 1.8 inches and boasting a resolution of 128 x 160 pixels. While these specifications seem modest by today's standards, they were quite satisfactory for basic tasks and navigation. The external CSTN display, with 4096 colors and a resolution of 101 x 80 pixels, provided quick access to essential notifications without opening the flip.
