A 3:4 vertical mechanical keyboard encyclopedia information poster, blending Bauhaus functionalism, industrial design archives and a modern digital laboratory aesthetic. At the top, a diagonal-cut composition displays a compact mechanical keyboard, with keycaps, mechanical switches, plate, PCB and stabilizers shown separately in an exploded view beside it; hard-soft hybrid studio lighting creates crisp micro-shadows. The title "机械键盘" is arranged along the left grid, with the English subtitle "Mechanical Keyboard", a circular category tag "输入设备／机械开关" (input device / mechanical switch), a structural exploded diagram and a keyboard size scale bar.
In the middle, using restrained red, yellow and blue accent colors and modular geometric cards, present nine categories of information: common layouts 60%, 65%, 75%, 80%, 96%, 100%; tactile curves of linear, tactile and clicky switches; actuation travel and total travel; actuation force; common keycap materials and profiles; wired, 2.4GHz and Bluetooth connection methods; hot-swappable vs soldered PCB differences; plate, sandwich structure and Gasket common internal structures; latency, polling rate, N-key rollover and use scenarios.
Each module keeps only one primary graphic, avoiding visual stacking. Use a 12-column grid, 48pt margins, 8pt baseline, unified 2pt linear icons. Background is near-white light grey, text dark grey, data in monospaced font. At the bottom, a terminology explanation and parameter source bar, clearly stating "differences exist among brands and models", forbidding fabricated specific model performance or nonexistent technical standards.
一张 3:4 竖版机械键盘百科信息海报，融合包豪斯功能主义、工业设计档案与现代数码实验室视觉。顶部以斜切构图展示一把紧凑型机械键盘，并在旁边拆解展示键帽、机械轴体、定位板、PCB 和卫星轴，工作室硬柔结合光形成清晰微阴影；标题"机械键盘"沿左侧网格排列，英文副标题"Mechanical Keyboard"，搭配"输入设备／机械开关"圆形分类标签、结构爆炸图与键盘尺寸比例尺。
中部采用红、黄、蓝三种克制强调色和模块化几何卡片，完整呈现九类信息：60%、65%、75%、80%、96%、100%常见配列；线性轴、段落轴、点击轴触感曲线；触发行程与总行程；触发压力；键帽常见材质与高度；有线、2.4GHz、蓝牙连接方式；热插拔与焊接 PCB 区别；定位板、夹心结构与 Gasket 等常见内部结构；延迟、轮询率、全键无冲与使用场景。
每个模块只保留一种主要图形，避免视觉堆叠。采用12列网格、48pt边距、8pt基线、统一2pt线性图标。背景为接近纯白的浅灰，文字为深灰，数据使用等宽字体。底部设置术语解释与参数来源栏，明确"不同品牌与型号存在差异"，禁止虚构具体型号性能或不存在的技术标准。
