Samsung: new QLED TVs display stray colors in the image

In its test of Samsung’s latest QLED TVs, the German magazine reports a display problem that causes unpleasant screen artifacts to appear. The problem would be due to the triangle structure of the sub-pixels, rather than side by side as is usually the case. The Korean firm defends itself by ensuring that its televisions obtain better contrasts and that the problem is only rarely visible.

At CES 2021, Samsung presented its very first QLED TVs, promising a real revolution in the market. This new panel technology indeed combines all the benefits of OLED with those of quantum dots in order to obtain a more saturated and bright image. To do this, QLED TVs differ from other models in one very specific way: the structure of its RGB sub-pixels. Where a classic configuration places these side by side, Samsung’s QLED TVs position them in a triangle.

This architecture, called PenTile by the manufacturer, shares the blue and red sub-pixels between two green sub-pixels. Although innovative, the latter seems to come with a size problem. Indeed, as tests by the German magazine Heise show, green artifacts appear on screen, especially when the image is still. They are found in particular around texts and images, such as the Windows window closing cross. They are also present in game, like around buildings in Cyberpunk 2077.

Samsung defends itself against the display problem of its QLED TVs

Asked about the subject by FlatPanel, Samsung recognizes the existence of these parasitic tasksfurther specifying that the latter are also “visible on conventional LCD and OLED screens using the RGB strip”. According to the manufacturer, the problem appears when the screen is set to high brightness or high contrast. “Displays with better contrast modulation performance, wider color gamut and higher contrast ratio will accentuate this artifact”underlines the firm.

However, Samsung believes that this problem is not really a problem. The manufacturer thus argues by asserting that the artefacts are almost invisible when the image is in motionas well as when positioned at a reasonable distance from the screen, which most tests seem to confirm. “For true-to-life color and HDR performance (cinema and gaming), this display will deliver the highest experience”concludes Samsung.
