Apple Incorporated is facing a class action lawsuit alleging the company advertised the LCD screens on its MacBook and MacBook Pro laptops as being superior, but knowingly shipped screens that did not meet its original claims. The class action lawsuit points out Apple advertised that the new glossy screens introduced with its MacBook last year provided users with deeper blacks and whites that are more vibrant. However, many customers experienced graininess and sparkling effects common to dithering techniques, according to the complaint: "Many such dissatisfied purchasers were chastised by Apple agents and employees for being too picky about their assessments of the quality of the display. Other dissatisfied purchasers were told that they were imagining the complained about defects."
The complaint also points out that many of the disgruntled customers posted messages on Apple's own forums only later to have their posts moderated or completely removed by Apple forum administrators. The lawsuit alleges Apple uses dithering techniques to create an illusion of colors that don't actually exist. In fact, the lawsuit claims if a MacBook or MacBook Pro users installs Windows XP, they will notice superior image quality in areas such as gradients. The test seems to indicate Apple is using some sort of software at work in OS X. "The displays are only capable of displaying the illusion of millions of colors through the use of a software technique referred to as 'dithering'," the lawsuit claims.
