Why does my phone screen have lines in it

A damaged screen on a smartphone or any electronic device can often result in the appearance of lines on the display. These lines are typically caused by a disruption in the liquid crystal or OLED technology within the screen. When the screen is damaged, such as through impact or pressure, this disturbance can cause the pixels to malfunction. As a result, lines may appear, indicating areas where the pixels are not functioning correctly. These lines can manifest in various forms, such as vertical or horizontal lines, or even a spiderweb-like pattern.
