6、omparetion;Proposals3引言 引言壓電式的觸摸屏技術(shù)是一種處于電阻式觸摸屏技術(shù)和電容式觸摸屏技術(shù)之間的技術(shù)。電阻式的觸摸屏技術(shù)雖然成本低，性能穩(wěn)定，反應(yīng)快，但是它的透光率低，而且不能進(jìn)行多點(diǎn)操作。電容式的觸摸屏可以進(jìn)行多點(diǎn)操作，有較高的透光率，整體功耗低，使用壽命長(zhǎng)，但是，缺點(diǎn)就在于它只能通過類似于皮膚的材質(zhì)去觸控。壓電式傳感器的觸控屏幕同電容式觸控屏一樣支持多點(diǎn)觸控，然而，它是通過壓力來觸控的，所以什么材質(zhì)的東西去觸
