2025-12-30 In industrial display systems, visual consistency is critical. When a localized bright area—commonly referred to as a white spot—appears on an LCD, it often raises concerns about quality, reliability, and long-term performance. Unlike consumer electronics, industrial displays operate under harsher conditions and longer lifecycles. As a result, white spots on LCDs are rarely cosmetic issues. They can indicate deeper mechanical, optical, or system-level design challenges. This article explains what white spots are, why they occur in industrial LCDs, and how they can be prevented through proper design and process control.
