TFT displays may have a small number of cosmetic imperfections and still conform to the display manufacturers cosmetic quality specifications.
Here are some guidelines to use in determining what action to take on a customer complaint of cosmetic imperfection in their TFT display:
1. The unit should be viewed in the customer's normal operating condition.
This means if the customer uses the unit predominately in DOS, or Windows, or in some other application or combination of applications, that is where the determination shall be made. Self test is not a normal operating condition and is not a sufficient tool to interpret display quality.
2. In the customer's normal operating mode:
| a. If 4 or more variant pixels appear clustered in the area approximated by a |
| thumbprint on the display surface, then the display should be considered for |
| replacement. |
| b. On OmniBook 4000CT models, if more than 30 total pixels anywhere on the |
| display are bad, then the display should be considered for replacement. On |
| OmniBook 600CT and OmniBook 5000CT models, if more than 15 total pixels |
| anywhere on the display are bad, then 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, it should be clear to the customer that |
| cosmetic variations on the replacement display may also exist, and may require the |
| customer to use a |
| 4. Customers with |
| above conditions and tests will not normally be considered for display replacement. |
| It will be left to the judgment of the |
| customer, to identify |
| individual customer. Customers who must have a more perfect display solution |
| should consider switching to an OmniBook with a DSTN display. |
| We expect over time that the industry will continue to improve in their ability to |
| produce displays with fewer inherent cosmetic imperfections and will adjust our HP |
| guidelines as the improvements are implemented. |
