SEOUL, South Korea, Feb. 26, 2026 /PRNewswire/ — LG Show, the world’s main innovator of show applied sciences, at the moment introduced that every one of its large-sized OLED panels, together with these for TVs and screens, have been acknowledged for his or her “excellent dimming know-how” – incomes the trade’s first “100% dimming consistency” verification from UL Options, a worldwide chief in utilized security science. This efficiency, as validated by UL Options, objectively demonstrates the prevalence of OLED’s pixel-level dimming.
LG Show earns trade’s first “100% dimming consistency” verification
Dimming consistency refers to a measurement technique that evaluates, in share phrases, how successfully a show reproduces content material based mostly on its brightness efficiency. A reference space is ready within the middle of the display and is progressively diminished from 1/10 of the panel to 11/1000, 5/1000, and at last 2/1000. The outcomes are expressed as a share: if the utmost and minimal brightness values stay the identical all through the method, dimming consistency is 100%. Conversely, as the worth decreases, it means that there’s mild depth variation inside the identical display. In such circumstances, brightness differs relying on the place of the sunshine supply, even for a similar colour.
LG Show’s OLED maintained the identical brightness efficiency even because the take a look at reference space decreased, attaining a dimming consistency charge of 100%. In distinction, LCD-based panels turned dimmer because the take a look at reference space shrank, with dimming consistency dropping from a most of 83% to as little as 43%.
This is because of variations in emission strategies. As a result of OLED panels emit mild on the pixel stage, with pixels measuring solely about 0.1 mm², they’ll keep brightness even when the take a look at reference space is diminished, reproducing pure colours and clearly distinguishing colour boundaries. This implies they’ll faithfully categorical the content material creator’s authentic intent.
By comparability, RGB Mini LED, the most recent LCD TV know-how, depends on backlight blocks which are 160,000 to 830,000 occasions bigger than the pixels of an OLED panel, revealing limitations in reproducing pure colours. As brightness diminishes towards the sides of the backlight blocks, it turns into troublesome to obviously distinguish colour boundaries, leading to diminished colour accuracy. Mild bleeding, referred to as the halo impact, can also happen.
With the halo impact, mild leaks from the boundaries of the backlight blocks of an LCD panel, inflicting the picture to look hazy. For instance, when a vivid star in a darkish sky is smaller than the world of a backlight block, the boundary between the starlight and the darkish sky might not be rendered clearly, making the picture seem blurred.
This additional highlights OLED because the optimum show for connecting people and AI. Within the AI period, excessive luminance, excessive decision, and excessive colour gamut efficiency are important – enabling brighter, sharper, and extra correct colour copy. Having achieved 100% dimming consistency, OLED can ship the wealthy visible info generated by AI in a pure and exact method.
LG Show plans to additional strengthen its large-sized OLED management based mostly on this world-leading OLED know-how. The corporate’s new OLED TV panel applies its proprietary “Main RGB Tandem 2.0” know-how, which emits mild by stacking the three major colours of sunshine – purple, inexperienced, and blue – in unbiased layers. It delivers a peak luminance of as much as 4,500 nits (one nit equals the brightness of a single candle) and incorporates know-how that absorbs and disperses mild moderately than reflecting it, attaining the bottom reflectance stage (0.3%) amongst current shows.
Hyeon-woo Lee, Head of LG Show’s Giant Show Enterprise Unit, stated, “Now we have objectively recognized why OLED seems brighter and clearer. By this verification, we will extra clearly clarify to prospects that OLED’s pixel dimming know-how, which maintains 100% dimming consistency, is the optimum selection within the AI period.”
