另一方面，硬件集成的防窥屏幕也是在 2026 电子产品大涨价、硬件配置边际效应递减的大背景下，维持持续吸引力的关键卖点。
近年来，各国大举兴建数据中心，对HBM形成饕餮需求，使芯片厂将产能转向利润高出数倍的HBM，而生产1GB HBM所消耗的晶圆产能，大约是生产1GB普通DDR5内存的3倍以上，这严重挤压了手机所用内存的供应。

Poincaré half-space model. Take the open upper half-space \[\mathbb{H}^n := \{(x_1,\dots,x_n)\in\mathbb{R}^n \mid x_n 0\}\] equipped with the Riemannian metric whose components on the coordinate tangent vectors are \[g_{ij}(p) \;=\; g_p\!\left(\frac{\partial}{\partial x_i}\bigg|_p,\; \frac{\partial}{\partial x_j}\bigg|_p\right) \;=\; \frac{1}{p_n^2}\,\delta_{ij}.\] Geodesics are semicircles (or rays) orthogonal to the boundary hyperplane \(\{x_n = 0\}\).
