LCD Display Pixel Introduction
LCD displays are made up of a set number of pixels and each pixel is made from 3 sub-pixels - one Red, one Blue and one Green. Each sub-pixel has its own transistor, which makes manufacturing the glass substrate very complex.
Due to the nature of the manufacturing process, occasional defects can occur. Pixel defects or failures cannot be fixed or repaired and can happen at any stage in the LCD’s life. There are two types of pixel defects:
This International Standards Organization Standard defines a specification for classes of pixel defects as detailed below:
Class 0 products have no pixel or sub pixel defects.
Class 1 products can have all or any of the following defects:
Dead Pixel Warranty Policy
The table below shows the allowable number of dead sub-pixels for the native resolution of the LCD panel. Your display can be replaced during the duration of the limited warranty period if the number of dead pixels is greater than the allowable number.
We strives to deliver the highest quality products and therefore use some of the industry's most advanced manufacturing processes and practice stringent quality control. However, pixel or sub pixel defects on LCD Monitor panels are sometimes unavoidable. No manufacturer can guarantee that all panels will be free from pixel defects, but we guarantees that any LCD Monitor with an unacceptable number of defects will be repaired or replaced under warranty.

Due to the nature of the manufacturing process, occasional defects can occur. Pixel defects or failures cannot be fixed or repaired and can happen at any stage in the LCD’s life. There are two types of pixel defects:
- Bright Sub-Pixel: A sub-pixel is displayed as a small white dot on a black pattern.
- Dark Sub-Pixel: A sub-pixel is displayed as a small black dot on a white pattern.
This International Standards Organization Standard defines a specification for classes of pixel defects as detailed below:
Class 0 products have no pixel or sub pixel defects.
Class 1 products can have all or any of the following defects:
- 1 Bright Pixel (All sub pixels are bright)
- 1 dark Pixel (All sub pixels are dark)
- 2 single or adjacent bright or dark sub pixels
- Up to a total of 5 bright or dark sub pixels (determined by type)
- 2 Bright Pixel (All sub pixels are bright)
- 2 dark Pixel (All sub pixels are dark)
- 2 single or adjacent bright or dark sub pixels
- Up to a total of 10 bright or dark sub pixels (determined by type, bright sub pixels cannot exceed 5)
- 5 Bright Pixel (All sub pixels are bright)
- 15 dark Pixel (All sub pixels are dark)
- Up to a total of 50 bright or dark sub pixels
