[QUOTE="xavito, post: 1058758908, member: 13356"] Samsung responds to concerns over QD-OLED pixel structure...[URL]https://www.flatpanelshd.com/news.php?subaction=showfull&id=1648029400[/URL] [I]Samsung Display's new QD-OLED displays use a special triangular pixel structure that can cause color fringe artifacts. The company does not see it as an issue in the "vast majority of use cases". Why has Samsung Display, the manufacturer of the QD-OLED panels, chosen to position the three red, green and blue subpixels that together form each pixel in a triangle rather than using the more conventional RGB stripe layout?[/I] - [I]"It is not a typical RGB stripe pixel – but our proprietary structure optimized to enhance the core user experience of color and HDR. We selected this new pixel structure in order to optimize optical characteristics of QD-Display like brightness, color gamut and durability. Each pixel of QD-Display has an individual Red, Green and Blue – 3 primary sub pixels,"[/I] Samsung Display said in a statement to FlatpanelsHD. - [I]"Unlike Pentile sub-pixel structure that share the adjacent sub-pixel and compromise on detail and accuracy, QD-Display has 3 (R,G,B) x (3440*1440) sub-pixels. So, QD display does not compromise on the detail and accuracy."[/I] [B]Samsung: Can also happen with RGB stripe[/B] Samsung Display further argued that similar color fringe artifacts can be seen on conventional RGB stripe-based displays but that displays with high contrast modulation and a wider color gamut, such as QD-OLED, can accentuate the effect. - [I]"The artifact pointed out also can be seen on conventional LCD and OLED displays using RGB stripe. Similar phenomenon is observed on the sides (Left and Right) side when displaying bright high contrast edge on conventional display products,"[/I] Samsung Display told FlatpanelsHD. [I]"Displays with better contrast modulation performance and wider color gamut and greater contrast ratio will accentuate this artifact. Because QD-Display has the widest color gamut, superior contrast ratio and new sub pixel structure, this artifact could be visible."[/I] Although the color fringe effect can reportedly be seen on QD-OLED displays when sitting close to the screen, Samsung Display believes that it will not be an issue in the majority of use cases.
