through gaps in the liquid crystal layer, diffuser plate, or polarizer film. They are commonly caused by physical pressure, thermal stress, manufacturing defects, or aging backlight components. While some pressure-induced spots may fade, most white spots require panel repair or replacement. For industrial and medical applications, prevention through optical bonding and reinforced mechanical design is the most reliable solution. What Are LCD White Spots? LCD white spots (also called white patches, clouding, or light leakage) are visible bright areas on a display where the backlight passes through the panel unevenly.
