How does touch screen perform under low temperature conditions?

Most users may have a question that whether PCAP touch screen will be affected under low temperature. Apparently yes, the lower the temperature, the greater the impact. This article will explore the performance under low temperature, the reasons and the solutions.

The performance of PCAP touch screen under low temperature

Response speed turns slow. Under low temperature, touch screen will not be very flexible. When users click or slide, touch screen may respond very slowly. What’s worse, touch screen will even occur touch sensing failure.

The sensitivity of PCAP touch screen. When the touch screen lies in a low temperature, it will not be very sensitive, which means it needs a heavier pressure compared with light pressure in normal temperature.

Abnormal Display of PCAP touch screen. Low temperature will lead to abnormal display of touch screen, for example, the touch may change the color, flash and so on.

The problems above will decrease the sense of users’ experience. So find out the reason is very important.

Reasons for the impact of low temperature on PCAP touch screen

Material characteristics and electronic component failure. Some materials’ physical and chemical quality will be changed by low temperature. For example, glass will turn more fragile under a low temperature and easily break.

Decreased battery performance. Obviously, touch screen always depends on battery. However, in such a low temperature, according to the principle of thermal expansion and contraction, battery’ s capacity will reduce, which is not good for touch screen normal working.
