LG Display reveals world’s first 4K 240Hz OLED gaming monitor with a real RGB “striped” subpixel format — New panel succeeds WOLED with multi-stack Tandem OLED

Ahead of CES 2026, LG Display has just announced a seemingly revolutionary development within the OLED world, no less than so far as its personal panels are involved. The firm has achieved a striped, true RGB subpixel format in one in all its upcoming screens — particularly, a 27-inch 4K show with a 240 Hz native refresh price, doubled by dual-mode capabilities.

To perceive why that is such a giant deal, we first have to take a look at how subpixel constructions inform the picture high quality that you just see. Every show has pixels, and every of these pixels are made up of tiny pink, inexperienced, and blue (RGB) subpixels. However, LG’s panels additionally add a fourth white subpixel within the equation to spice up brightness.

See, OLED panels are inherently weak in the case of being shiny as a result of driving these candy natural pixels as onerous as attainable will put on them out shortly, resulting in burn-in. Therefore, you want ingenuity to sort out this challenge, and to date, LG has relied on that white subpixel for probably the most half, however that comes with a draw back.

Even although the inherent luminance of the picture is boosted, the colour quantity is damage as a byproduct of what white subpixel basically bleeding over the opposite colours. This is why Samsung’s QD-OLED panels are touted for his or her superior colour efficiency, since they do not have a white subpixel and as an alternative emit blue mild that passes by quantum dots to filter colours.
