触摸屏如何感知触碰

一张技术信息图,讲解电容式触摸屏如何工作,呈现为手机屏幕的分层爆炸图。带标注的各层——保护玻璃、透明电极网格、传感层与显示屏——竖向分开;一根指尖触碰顶层,一个放大插图展示网格处被检测到的电荷变化。干净的科技美学,冷灰与青配色,珊瑚色触点点缀,深炭黑底。左上角粗体标题「触摸屏如何感知触碰」,编号的层级标签,一个小的网格坐标读数。

A technology infographic explaining how a capacitive touchscreen works, shown as an exploded layer stack of a phone screen. Labeled layers - protective glass, a transparent electrode grid, a sensor layer, and the display - separate vertically; a fingertip touches the top, and a zoomed inset shows the electrical charge change detected at the grid. A clean tech aesthetic, a cool grey-and-cyan palette with a coral touch-point accent on dark charcoal. Bold title 'How a Touchscreen Senses You' top-left, numbered layer labels, a small grid-coordinate readout.
