Important Tips
Image Retention Effect(Image Sticking)
1. Cause :
- If LCD TV displays the same pattern for a long period of time, Image Retention Effect may develop
due to the LCD structure.
- This is a common phenomenon that occurs in all LCD products on current market.
2. Prevention :
- To avoid this matter, use the product after reducing brightness and contrast, especially when a still
image is displaying for a long time. (Example : Contrast 50, Brightness 50 - See the page 36)
Once Image retention occurs, change the mode into Video mode which displays more motion
pictures. It will help reduce this effect, but cannot completely eliminate the effect once it occurs.
When a fixed pattern is displayed often, screen brightness may get worse.
3. Solution :
- Displaying a full white pattern for around 10 hours might help reduce latent image effect temporarily.
- It is not possible to permanently prevent Image Sticking Effect using current technology.
4. Notice :
- It is very important to notify every buyer/customer of this information and all distributors/buyers/
customers should be fully aware of this.
- A manufacturer cannot provide a technical support of Image Sticking Effect of LCD TV. And Warranty
does not include Image Sticking Effect.
Second Tip
• Pixel Defect:
LCD TV panel is made of a group of refined pixels (cells). Due to the technological constraints of
building an LCD chip, manufacturers can only guarantee that approximately 99.9% of pixels will be
functional. Only a few of abnormal pixels may appear but this has no influence upon LCD TV's
performance.
* Specification on ‘dead pixel’ of LCD panel complies to ISO13406-2 Standard.
