What They Say
The story about the colour fringing on the Dell Alienware QD OLED monitor, first reported by Heise.de, rumbles on. (Triangle Sub-Pixels Causing Concern on Dell QD-OLED Monitors). SDC has been out in ‘fire-fighting’ mode since. The company wrote to FlatPanelsHD and said that there is a full RGB triad for each pixel, although it is not in a stripe shape, and that the data is not shared between pixels as it is in some smartphones derived from the ‘Pentile’ sub-pixel addressing.
It also pointed out that this kind of fringing can also be seen on the edges of other RGB displays with stripes. It also pointed out that the effect is more visible partly because the display has WCG and extreme contrast.
What We Think
Windows has a function to adjust the subpixel rendering of text. You used to be able to optimise it, but it seems to be set as a single default, now. I just found out how to turn it off and the result on my system, with an UltraHD display, was horrible. I have reached out to CT Magazine to check if that was tested – we have a close relationship with the publication as it regularly translates and re-publishes Display Daily articles.
The original Pentile concept used a five way subpixel arrangement, with two red, two green and one blue to exploit the way the eye works. Candice Brown-Elliott was the inventor and has written for Display Daily in the past. These days, she has retired from the display industry after selling her company to Samsung and helping the firm to integrate Genoa, which made multi-primary displays. She also ran Nuovoyance which developer her ideas. These days, she focuses on teaching flying, gardening and writing (among other things).
Dell is, of course, focusing its attention on gaming and I would be amazed if any kind of artefact would put off gamers, given the fantastic contrast, colour and response times of OLED displays. It certainly should look good on video – the ‘delta’ kind of sub-pixel arrangement was the one of choice for CRTs for that application, back in the day. (BR)
