User Manual BDL5571V

6.3. BRIGHT DOT DEFECTS

Bright dot defects appear as pixels or sub-pixels that are always lit or "on". These are the examples of bright dot defects:

One lit red, green or blue sub-pixel

Two adjacent lit sub-pixels:

-Red + Blue = Purple

-Red + Green = Yellow

-Green + Blue = Cyan (Light Blue)

Three adjacent lit sub-pixels (one white dot)

6.4. DARK DOT DEFECTS

Black dot defects appear as pixels or sub-pixels that are always dark or "off". These are the examples of black dot defects:

One dark dot

Two adjacent dark dots = 1 pair of dark dots

Two dark dots, specifications defines the minimum distance between dark dots

6.5. PROXIMITY OF PIXEL DEFECTS

Because pixel and sub-pixels defects of the same type that are nearby one another may be more noticeable, Philips also specifies tolerances for the proximity of pixel defects. In the table below you can find specifications about:

Allowed amount of adjacent dark dots = (adjacent dark dots =1 pair of dark dots)

Minimum distance between dark dots

Total no. of all defective dots

6.6. PIXEL DEFECT TOLERANCES

In order to qualify for repair due to pixel defects during the warranty period, a PDP / TFT panel in a Philips Plasma / LCD- display must have pixel or sub-pixel defects exceeding the tolerances listed in the following table.
