Currently, OLED and MiniLED each have their advantages and disadvantages: OLED essentially treats each pixel as a separate LED, creating a distinct area. Its black level performance is undeniable, and color reproduction is easily improved. However, being organic, it carries the risk of premature aging due to overheating. Therefore, it generally employs an ABL (Alternating Brightness Blur) mechanism, where the larger the white window area, the greater the brightness reduction. A 1% white window might have 1000 nits, but a 100% white screen would only have 250 nits – and this is a common practice. Why can smartphones maintain this brightness? Because they are small. A 5% white window on a 27-inch screen is roughly the size of a smartphone. Furthermore, OLED fundamentally cannot solve the flicker problem; the 100% flicker depth is unpleasant, and the risk of burn-in makes it unsuitable for displays, as displays cannot constantly display different content like smartphones. The situation with MiniLED is more chaotic. It should actually be called direct-lit backlighting, but many products label it as a panel, and its calibration lacks a unified standard. Unlike OLED, miniLED's main advantage lies in brightness. It doesn't require an ABL (Adaptive Backlighting) mechanism, hence its frequent HDR1000 certifications. It's better suited for bright environments, the opposite of OLED. Furthermore, unlike OLED, it doesn't rely on turning off pixels for refresh, so flicker isn't always necessary; some products can even achieve zero-flicker backlighting.
However, miniLED's disadvantage is inaccurate content rendering. The purpose of zone control is to suppress black levels, but in reality, most displayed content won't consistently present a large black area or a black area the size of a single LED for adjustment. If you try to suppress blacks, nearby non-black content will inevitably be darkened as well, resulting in inaccurate content rendering.
This creates a dilemma: do you sacrifice brightness and color accuracy to ensure accurate black levels, or sacrifice black levels to ensure accurate overall content reproduction? This is an unavoidable issue with miniLEDs, and manufacturers currently tend to favor the former (OLED), leading to extremely extreme viewing experiences. One second you might find it so dark you can't see anything, and the next second you open a folder and the entire screen becomes a flash of light. Most importantly, you don't know the true brightness or darkness of the content; are you seeing the content the creator intended? Therefore, I believe neither is a viable long-term technology. OLED's organic components and circuitry inherently limit its lifespan and flicker issues. MiniLED, when pushed to its limits, becomes microLED, which is a completely different thing. And is microLED the future? It's hard to say. Inorganic LEDs have a minimum luminance threshold, and it's difficult to say whether the flicker problem can be solved.
