Pixel Policy for IdeaPad

The thin-film transistor (TFT) liquid crystal display (LCD) for notebook computers contains many TFTs. The presence of a small number of missing, discolored, or lit all the time dots or pixels is characteristic of TFT LCD technology due to manufacturing process for such technology irrespective of manufacturer.

If your LCD has defective pixels, it should not be considered faulty until the number of defective pixels meets or exceeds the number listed in the criteria table. Where the number of defective pixels is equal to or greater than the number listed in the criteria table, the LCD will be deemed faulty and will be replaced if within the warranty period if requested.
