Hewlett-Packard Display Quality Statement
TFT display manufacturing is a highly precise but imperfect technology, and manufacturers cannot
produce large displays that are cosmetically perfect. Most, if not all, TFT displays exhibit some level
of cosmetic imperfection. These cosmetic imperfections may be visible to the customer under varying
display conditions, and can appear as bright, dim, or dark spots.
This issue is common across all
vendors supplying TFT displays in their products and is not specific to the HP notebook display.
HP notebook TFT displays meet or exceed all HP standards for cosmetic quality of TFT displays. HP
does not warrant that the displays will be free of cosmetic imperfections.
TFT displays can have a
small number of cosmetic imperfections and still conform to HP’s cosmetic quality specifications.
Here are some guidelines for determining what action to take on customers’ complaints of cosmetic
imperfections in their TFT displays:
1.
View the unit under the customer’s normal operating conditions.
This means that if the customer uses the unit predominately in DOS, in Windows, or in some
other application or combination of applications, you should make the determination under those
same applications. Self test is not a normal operating condition and is not a sufficient tool for
interpreting display quality.
2.
Use the table below to determine whether the display should be considered for replacement.
These are the only conditions in this guideline that may call for a replacement due to a defect in
material or workmanship based on the HP Limited Warranty Statement.
3.
If a display is considered for replacement, make sure the customer understands that cosmetic
variations may also exist on the replacement display, and may require the customer to use a work-
around to obscure the cosmetic imperfection.
4.
Displays with cosmetic imperfections that do not conform to the above conditions and tests will
not normally be considered for replacement. The HP-responsible person working with the
customer should identify work-arounds that are reasonable and appropriate for that customer.
Customers who require a more perfect display solution should consider switching to a notebook
with a DSTN display.
We expect that over time the industry will continue to produce displays with fewer inherent cosmetic
imperfections, and we will adjust our HP guidelines as these improvements are implemented.
