P hilips s trives to deliver the highes t quality products . W e us e s ome of the indus try's mos t advanced manufacturing proces s es and practice s tringent quality control. However, pixel or s ub pixel defects on the T F T LC D panels us ed in flat panel monitors are s ometimes unavoidable. No manufacturer can guarantee that all panels will be free from pixel defects , but P hilips guarantees that any monitor with an unacceptable number of defects will be repaired or replaced under warranty. T his notice explains the different types of pixel defects and defines acceptable defect levels for each type. In order to qualify for repair or replacement under warranty, the number of pixel defects on a T F T LC D panel mus t exceed thes e acceptable levels . F or example, no more than

0.0004% of the s ub pixels on a 19" XG A monitor may be defective.

F urthermore, P hilips s ets even higher quality s tandards for certain types or combinations of pixel defects that are more noticeable than others . T his policy is valid worldwide.

B lack Dot Defects B lack dot defects appear as pixels or s ub pixels that are always dark or 'off'. T hat is , a dark dot is a s ub-pixel that s tands out on the s creen when the monitor dis plays a light pattern. T hes e are the types of black dot defects

P ix els and S ub pix els

A pixel, or picture element, is compos ed of three s ub pixels in the primary colors of red, green and blue. Many pixels together form an image. W hen all s ub pixels of a pixel are lit, the three colored s ub pixels together appear as a s ingle white pixel. W hen all are dark, the three colored s ub pixels together appear as a s ingle black pixel. Other combinations of lit and dark s ub pixels appear as s ingle pixels of other colors .

Types of P ix el Defec ts

P ixel and s ub pixel defects appear on the s creen in different ways . T here are two categories of pixel defects and s everal types of s ub pixel defects within each category.

B right Dot Defects B right dot defects appear as pixels or s ub pixels that are always lit or 'on'. T hat is , a bright dot is a s ub-pixel that s tands out on the s creen when the monitor dis plays a dark pattern. T here are the types of bright dot defects :

P rox imity of P ix el Defec ts

B ecaus e pixel and s ub pixels defects of the s ame type that are near to one another may be more noticeable, P hilips als o s pecifies tolerances for the proximity of pixel defects

P ix el Defec t Toleranc es

In order to qualify for repair or replacement due to pixel defects during the warranty period, a T F T LC D panel in a P hilips flat panel monitor mus t have pixel or s ub pixel defects exceeding the tolerances lis ted in the following tables .
