Your Phone Screen Has a Surprising Secret—Strange Horizontal Lines Ruining Your Vision In today’s ultra-slim, high-resolution smartphone era, many users shrug off small display quirks—until strange horizontal lines start creeping across their screens. These mysterious lines—sometimes diagonal, sometimes perfectly horizontal—can seriously disrupt your reading, scrolling, and overall visual experience. Worse, few realize these lines aren’t just a cosmetic nuisance; they may stem from deep technical secrets built into your device. ### What Causes Horizontal Lines on Phone Screens? Horizontal lines, often referred to as “screen artifacts” or “ghost lines,” are most commonly caused by Pixel Area Displays (PADs) technology, a relatively new approach to smoother image rendering. Instead of using traditional sub-pixel arrangement (like RGB pixels in standard OLED/lCD), PADs group pixels into larger, flexibly arranged areas—sometimes spindle or hexagonal clusters—that adapt dynamically to scene content. While this boosts visual smoothness and detail, the shifting light reflection patterns can produce faint horizontal stripes across the screen.
