You may be seeing one or more of the greater than 2,000,000 dots that make up the composition of your LCD or OLED screen. These dots (pixels) may appear red, green, blue, white, or black.
High-precision technology is used to manufacture LCD and OLED displays to maintain a high standard of operation. However, with all LCD/OLED screens, regardless of manufacturer, a small number of dots may not change color. This is normal operation for LCD and OLED screens for all manufacturers. Most defects are only noticeable when an all-white or all-black picture is displayed and shouldn't be noticeable under normal operation.
Because a defective pixel or pixels is normal on all LCD or OLED screens, there's a high chance that a replacement screen may also have them. It's possible that the replacement could have more defective pixels, or the pixels may appear in a more noticeable position.
- Debris on the screen can appear as dead or defective pixels. Clean the screen thoroughly with a microfiber cloth to confirm whether or not the issue is a defective pixel or due to dirt or debris.
- Sometimes dead or defective pixels correct themselves over time.
