電阻式觸摸屏的缺點

儘管電阻式觸摸屏得到廣泛使用,但也存在相當大的缺點,這給其他觸摸技術提供了立足並擴大市場份額的機會。用戶始終對電阻式觸摸屏感到沮喪,電阻式觸摸屏無法準確地報告觸摸屏不同部分上的按鈕激活情況,或者未按預期激活按鍵。由於電阻式觸摸屏依賴於壓力-激活觸摸,因此需要移動和彎曲其堆疊中的不同層-。此外,頂部硬塗層需要足夠​​薄,以保持觸摸屏面板的柔韌性。移動層和薄保護層的結合會導致耐用性降低並且容易被劃傷。

電阻式觸摸屏還存在光學透射率較低的問題(< 80%). The construction of resistive touchscreens with two layers of PET, an air gap, and spacer dots can render a loss of refractive and reflective light, thereby yielding a more shaded display. Another negative attribute is that resistive touchscreens suffer from aging, which starts to occur when PET breaks down at high temperature. Signs of aging include touchscreen discoloration, where the touchscreen starts to turn white in color. Resistive touchscreens also have the disadvantage of requiring calibration. Calibration is needed to compensate for ITO-sheet resistance drift on PET.
