提示词库 · 手机壁纸
十个实测的竖版提示词——风景、抽象和微距世界，都按手机屏幕构图，给时钟和图标留出位置。每张图都是旁边提示词未经修改的输出。
壁纸提示词和普通图像提示词的区别有两点：画幅比例和构图。永远按9:16生成——事后把横图裁成竖图，等于把构图扔掉。然后为屏幕做设计：把主体放在画面下方三分之二处（大多数锁屏的时钟在上三分之一），偏爱竖向元素——瀑布、塔楼、树干、光束——想让时间后面有块干净区域时，就写上「negative space at the top」。
风格上，壁纸偏爱饱和的颜色和简单可读的形状：细节繁复的场景在应用图标后面会变成噪点。下面十个例子都是在BananaBanana上按9:16生成的，每张卡片标注了所用模型。用$0.03的Nano Banana 2 Lite，每天早上换一张新壁纸，一个月也就一美元。
下面每张图片都是所在卡片提示词的未修输出——没有从几十次尝试里挑好的，也没有修图。模型徽标标明了它由什么生成、花了多少钱。
Vertical phone wallpaper of a green and violet aurora borealis swirling above jagged snow-covered peaks, a small mirror-still lake in the foreground reflecting the sky. Stars visible between the aurora bands, deep night blues, main ridgeline in the lower third leaving open sky at the top.
Minimal abstract vertical wallpaper of slow-flowing silk-like waves in a smooth gradient from deep violet through fuchsia to warm amber, soft studio light catching the folds. No hard edges, gentle grain, calm and premium, plenty of quiet space in the upper half.
Vertical wallpaper of a narrow rain-soaked alley at night lit by pink and cyan neon signs, reflections stretching down the wet pavement toward the viewer. Steam rising from a vent, umbrellas in the far distance, cinematic cyberpunk mood, light sources concentrated in the lower two-thirds.
Dreamy vertical wallpaper of fluffy pastel clouds in peach, lavender and baby blue at dusk, a thin crescent moon high in the sky. Soft airbrushed gradients, a few tiny stars, serene and weightless, clouds gathered toward the bottom with clear sky at the top for the clock.
Top-down vertical wallpaper of two koi fish — one white with orange patches, one deep gold — gliding through dark teal water dotted with lily pads and gentle ripples. Soft overhead light, fish curving around the center of the frame, tranquil Japanese garden aesthetic.
Vertical wallpaper of a towering interstellar nebula in violet, magenta and gold, a dense cluster of newborn stars glowing at its heart in the lower third. Wisps of cosmic dust rising like smoke toward a darker star field at the top, rich astrophotography detail, awe-inspiring scale.
Vertical wallpaper looking up a path through a dense green bamboo forest in morning mist, tall straight stalks converging toward soft glowing light at the top. Muted jade palette, dew in the air, peaceful and meditative, gentle depth haze.
Macro vertical wallpaper of translucent glass-like flowers with iridescent petals refracting violet and amber light, against a dark blurred background. Delicate stems rising from the bottom edge, tiny internal bubbles and light caustics in the petals, elegant and otherworldly.
Vertical wallpaper of rippled desert dunes under a brilliant starry sky, the Milky Way rising diagonally from behind the largest dune. Cool indigo sand shadows with warm highlights on the crests, one tiny distant campfire glow, vast quiet solitude, horizon kept low.
Luxurious abstract vertical wallpaper of black and deep violet marbled ink swirling in water, veined with fine metallic gold lines that catch the light. High-resolution fluid texture, slow elegant motion frozen in place, darker toward the bottom edge, opulent and modern.
在生成时就把画幅设成竖版。事后把16:9的图裁成竖图，会毁掉你要的那个构图。
要求主体「in the lower two-thirds」或「open sky at the top」——多数锁屏把时间画在居中主体本该在的位置上。
在主屏上，你的画面活在一格格图标后面。大胆的渐变、单一主体和干净的留白依然可读；密集的细节则变成噪点。
同一条提示词生成两次——一张安静的给主屏，一张更有细节的给锁屏。两张Lite图一共$0.06。
9:16的1K生成（大约768×1344）经系统缩放后，在大多数手机上已经足够锐利。旗舰屏幕或含细腻渐变的图，建议在Nano Banana 2或Pro上按2K生成，以避免出现色带。
Nano Banana 2 Lite以固定$0.03生成1K竖图——每天换一张，一个月大约一美元。把Pro留给渐变繁重或超高细节的设计，那里2K输出才值回票价。
可以——在提示词里点名确切的配色（「deep violet through fuchsia to warm amber」），或者把主题截图作为参考图上传，要求生成同一配色的壁纸。
先生成静态图，再把它作为图生视频的起始帧交给Veo 3.1，配一句轻微的运动提示词（「clouds drift slowly, stars twinkle」）——一小段循环在多数手机上就能当动态壁纸用。
