Philips Pixel Defect Policy One lit red, green or blue sub pixel Two adjacent lit sub pixels: - Red + Blue = Purple Three adjacent lit sub pixels - Red + Green = Yellow (one white pixel) - Green + Blue = Cyan (Light Blue) Black Dot Defects Black dot defects appear as pixels or sub pixels that are always dark or 'off'. These are the types of black dot defects: One dark sub pixel Two or three adjacent dark sub pixels Proximity of Pixel Defects Because pixel and sub pixels defects of the same type that are near to one another may be more noticeable, Philips also specifies tolerances for the proximity of pixel defects. Pixel Defect Tolerances In order to qualify for repair or replacement due to pixel defects during the warranty period, a TFT LCD panel in a Philips flat panel monitor must have pixel or sub pixel defects exceeding the tolerances listed in the following tables. BRIGHT DOT DEFECTS MODEL 1 lit sub pixel 2 adjacent lit sub pixels 3 adjacent lit sub pixels (one white pixel) Distance between two bright dot defects* 150P4 0 0 0 0 ACCEPTABLE LEVEL 150B4 0 0 0 150S4 8 or fewer 3 or fewer 1 or fewer 0 15 mm or more file:///D|/C/english/150p4cgbs/product/pixel.htm (2 of 3) [3/17/2003 7:14:45 PM]
