LCD Monitor Quality and Pixel Policy for Compaq TFT1501 Monitor

Compaq TFT1501 15-inch monitor

The Compaq TFT1501 monitor uses high-precision technology, manufactured according to HP standards, to guarantee trouble-free performance. Nevertheless, the monitor may have cosmetic imperfections that appear as small bright or dark spots. This is common to all LCD monitors used in products supplied by all vendors and is not specific to the Compaq TFT1501 LCD. One or more defective pixels or sub-pixels cause these imperfections.

•A pixel consists of one red, one green, and one blue sub-pixel.

•A defective whole pixel is always on (a bright spot on a dark background), or it is always off (a dark spot on a bright background). The first is the more visible of the two.

•A defective sub-pixel (dot defect) is less visible than a defective whole pixel and is small and only visible on a specific background.

The Compaq TFT1501 monitor does not have more than:

•10 total dot defects.

•10 defective full pixels.

•10 defective red sub-pixels.

•4 defective green sub-pixels (green is most visible).

•10 defective blue sub-pixels.

•No more than two adjacent (less than 2.5 mm edge-to-edge) and defective pixels.

•No more than two pairs of two adjacent defective pixels.

To locate defective pixels, the monitor should be viewed under normal operating conditions, in normal operating mode at a supported resolution and refresh rate, from a distance of approximately 50 cm (16 in.).

HP expects that, over time, the industry will continue to improve its ability to produce LCDs with fewer cosmetic imperfections and HP will adjust guidelines as improvements are made.
