Why does voltage difference cause image sticking on LG 43TNF5J Digital Signage?
- S
  Sara LawsonSep 8, 2025
  When the LCD panel displays a static image for an extended period of time, it can cause a voltage difference between the electrodes that operate the liquid crystals. When the voltage difference between the electrodes builds up over time, liquid crystals have a tendency to remain aligned in one direction. During this process, a previously displayed image remains visible. This phenomenon is referred to as image sticking.

  To prevent after-images on your LG Digital Signage: * If you use a fixed image for a long time, the pixels may be damaged. Use the screen-saver function. * When a dark image is displayed on the screen after an image with high contrast (black and white or gray), this may cause image sticking. This is normal for display products.
