LED有着诸多优势，被誉为未来十年电视屏幕的终极形态，但是目前技术依然不是很成熟，还有诸多缺点，咱们来详细讲一讲Micro LED的优点和缺点。\n\n![](https:\u002F\u002Fpic3.zhimg.com\u002F80\u002Fv2-50b907035bfd854b07cfdb303525bef1_720w.webp?source=1940ef5c)\n\n**优点：**\n\n一，不容易烧屏。\n\n当前OLED屏幕技术成熟而且价格也不算离谱，画面效果也非常好，但是由于采用了有机材料，长时间点亮会引起老化导致亮度变低，局部老化的快就会在屏幕上显现出无法消除的暗影，也就是消费者常说的烧屏。而Micro LED采用无机材料，就可以根治这个硬伤。\n\n二，亮度更高\n\n还是由于烧屏问题，OLED电视不敢太亮，也不敢长时间维持高亮，否则会加速老化，还专门搞出了ABL自动亮度限制这个功能来限制屏幕亮度。Micro LED就不用担心这个问题，因此画面会比OLED更为明亮。\n\n其他相比OLED来说比如对比度高、色域广都算是共有优势，尤其是与量子点材料结合后，色域会非常高。\n\n**缺点：**\n\n一，无法小型化\n\n不管是OLED还是液晶，4K清晰度条件下都可以小型化到55、65、75英寸，但是Micro LED受限于技术问题，单个灯珠还无法做的很小（像素密度低，PPI不行），因此要维持4K 清晰度，就要做百寸，市面上声称量产的Micro LED电视基本上都是上百英寸的。\n\n![](https:\u002F\u002Fpic3.zhimg.com\u002F80\u002Fv2-2197ae9c1f3c87c0bcbc33ba4fbb40e7_720w.webp?source=1940ef5c)\n\n二，拼接缝\n\n受限于巨量转移技术不成熟，百寸Micro LED屏幕无法一体成型，需要用多块单元板拼接组装成一整个大屏幕，因此是有拼接缝的，一定程度上影响观感。拼接有入户拼接和出厂前拼接两种，像三星的110英寸就是出厂的时候就拼接好了，但是通常要阳台吊装入户。\n\n![](https:\u002F\u002Fpic3.zhimg.com\u002F80\u002Fv2-54a942c66e4acdff04edc1ced0a6b5d0_720w.webp?source=1940ef5c)\n\n国产方案一般是入户拼接，进门方便，但是拼接缝更宽一点。\n\n![](https:\u002F\u002Fpic2.zhimg.com\u002F80\u002Fv2-76e75fecf8bc5ee655d86363ae0846ce_720w.webp?source=1940ef5c)\n\n三，Micro LED芯片波长一致性差\n\n上千万颗独立微型芯片，要让它们亮度和色彩一致，是极为困难的，如果波长不一样，那么亮度和色彩均匀性就会比较糟糕，影响画面效果，这也是目前Micro LED面临的技术难题。\n\n四，成本居高不下\n\n国产上百寸几十万，三星的上百万人民币，还远远达不到普通民用程度。\n\n![](https:\u002F\u002Fpic1.zhimg.com\u002F80\u002Fv2-a1f233419d3f4f63f496b706fcbff930_720w.webp?source=1940ef5c)\n\n说实话，现在销售的Micro LED电视只能算是有钱人装X的道具，产品还远远没有达到它应有的水平和效果，期待五年到十年后Micro LED电视走进千家万户。",[],{"left":4,"top":4,"width":5,"height":5,"rotate":4,"vFlip":6,"hFlip":6,"body":48},"\u003Cpath fill=\"none\" stroke=\"currentColor\"
