触摸屏

控制器是否需要额外的电源？

作为粗略的准则，您可以计算 6400 美元的一次性成本。此外，还可以购买大约 50 件您的个人触摸屏。 如果选择了特殊的客户特定选项，则这些值可能会更改，例如：

• 光学减反射涂层 -偏光器
• 特殊基板玻璃厚度

Decibel (dB) - a unit of power loss or attenuation used in EMI/RFI shielding:

1 decibel = 10 log (Power in/Power out).

A 3dB loss is a fifty percent power reduction.

Drift - a gradual loss of accuracy in the alignment of a touchscreen system. Over time, touches to the screen will gradually drift, or move away, from their proper on-screen targets. If the alignment of a touchscreen becomes poor, the touchscreen will need to be calibrated to restore proper alignment.
