Display
The main display of the VK3100 is a 2.2-inch TFT screen capable of displaying 256K colors, with a resolution of 176 x 220 pixels, which translates to a pixel density of approximately 128 ppi. It is sufficient for basic mobile tasks such as messaging and casual browsing. In addition to the main screen, the phone offers a 1-inch external CSTN display that supports 65K colors. Positioned on the outside, this smaller screen allows users to quickly check the time, caller ID, and notifications without opening the clamshell.
