What are bright dots (non-performing dead pixels)?
LCD is made up of pixels and each pixel is made up of three sub-pixel color valves of red, blue and green. The valves in each color either impedes or transmits the light source and by adjusting the amount of light passed through, each pixel displays a distinctive color that ultimately makes up the images shown on the screen. A dead pixel refers to a pixel with a defect in its ability to display the correct color output. When the defective pixel remains permanently lit, it is known as a bright dot and bright dots appear as a white or colored spots (except black) against a black background.
What can be done?
Dead pixels cannot be fixed after display assembly, which means non-performing pixels cannot be repaired and the only solution is to replace the LCD panel. However, LCD manufacturers have set limits as to how many bright dots are considered tolerable for a given panel based on the industry standard and manufacturing cost to provide users with a general guideline. Therefore, users often have no choice but to put up with defective displays when the number of dead pixels found is within the tolerance level. Depending on the manufacturer’s warranty policy, a panel exchange may not be guaranteed even if the dead pixel count
exceeds the industrial tolerance standard.
Why ASUS notebooks?
Shopping for a notebook can be a frustrating experience for some, since some stores do not allow display test runs before purchase. Once purchased and if the number of non-performing pixels found are above the tolerance level or are located at positions where viewing comfort is
considerably obstructed, it still depends on the company’s warranty policy to decide if a return is possible. However, here at ASUS, unyielding commitment to quality has driven the promise of zero bright dot in the three models, including W1, M6 and V6 notebook series. This
demonstrates ASUS’ confidence in product quality management as well as its determination to become the best provider of the high-quality 3C solutions. With this reassurance, users can now shop for ASUS notebooks with complete confidence for total satisfaction.
