True black: what self-emissive OLED actually changes
On an OLED display every pixel makes its own light and can switch fully off. This is what that does to contrast, motion and colour, and where it matters.
Two of the four references in Collection I, Nocturne 49 and Solitaire 27, use OLED panels. The difference between OLED and a conventional LCD is easy to state and hard to unsee once you have lived with it.
Light at the pixel
An LCD is a light valve. A backlight shines constantly behind the panel, and liquid crystals twist to block or pass that light at each pixel. Even when a pixel is told to show black, some backlight leaks through. Black on an LCD is a dark grey.
An OLED pixel is self-emissive. It produces its own light, and when it is told to show black, it switches off. There is no backlight to leak. Black is the absence of light.
That is why both of our OLED references list a contrast ratio of 1,500,000:1, against a few thousand to one for typical LCD panels. In a dim room, a star field looks like a star field, a black frame in a film looks like a closed curtain, and a dark interface stops glowing.
Motion
Because an OLED pixel changes state directly rather than waiting for liquid crystals to rotate, its transitions are extremely fast. Nocturne 49 and Solitaire 27 both specify 0.03 ms grey-to-grey response. Paired with high refresh rates (240 Hz on Nocturne, 280 Hz on Solitaire), moving images stay crisp, with none of the dark smearing that slow pixel transitions leave behind fast objects.
Colour
Self-emissive pixels also keep colour saturated in dark scenes, where an LCD's leaking backlight washes colour toward grey. Both of our OLED panels are 10-bit, able to address 1.07 billion colours, and cover 98–99% of the DCI-P3 cinema colour space.
Where it matters, and where it does not
OLED's advantages are most visible in mixed and dark content: film, photography with deep shadows, games, and any interface set to a dark theme. In a very bright room filled with white documents, the gap narrows, and full-screen brightness on OLED panels is typically more modest than on bright LCDs. Our specification sheets state brightness as a typical value (250 cd/m² on both OLED references) because that is what you will see day to day.
OLED panels also ask for a little care with static content over long periods. We cover the sensible habits here.
In short
OLED replaces a lit panel with lit pixels. The result is real black, near-instant response and colour that holds in the shadows. For anyone who works or plays in a dim, considered room, it is the single biggest improvement a display can offer.
