PIXEL POLICY
CTOUCH policy on defective pixel on LCD display
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 Green and one Blue. 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 panel life. To regulate the acceptability of defects and to protect the end user, ISO have created a standard for manufacturers to follow. ISO 13406-2 recommends how many defaults are acceptable in a display before it should be replaced, within the terms & conditions of warranty. All reputable manufacturers conform to and support the ISO 13406-2 standard.
There are three types of pixel defects covered under ISO 13406-2:
- Bright Pixel: A pixel is displayed as a small white dot on a black pattern.
- Dark Pixel: A pixel is displayed as a small black dot on a white pattern.
- Stuck sub-Pixel: A sub-pixel (red, blue or green) is always on, always off or partial bright.
One Pixel = 3 Sub-Pixels
Dead Pixel Warranty Policy
The table 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.
