LG Display has different M+ RGBW configurations for TV & ITLG has been developing its algorithms for RGBW pixel configurations and the technique can be especially useful where you need to boost brightness for HDR display. In low grey scale parts of the image, the white pixel can be turned off to help to maintain colour saturation at low grey levels. The RGBW pixels are also useful in transparent displays and for outdoor applications. LG has developed a different M+ RGBW configuration that is for IT and mobile/automotive applications. These use a smaller white pixel than other approaches and allows bigger sub-pixels. Clever sub-pixel addressing is needed to ensure good performance in text applications (the RGBW configurations that are good for TV, often don’t work so well on text).
Next we looked at an 8K “technology demo” 98″ panel. This is ready for market from a technical point of view, but at the moment, LG doesn’t see a market for it. This will change as we get nearer to 2020.
As well as the panel itself, LG is looking at the driving of its panels and has built and UltraHD upscaler into the TCon of some of its UltraHD panels, so that the set maker does not have to change anything from the chassis side to support UltraHD panels. To boost subjective sharpness and resolution, the firm has its MSE technology which performs some edge sharpening.
