• Prevent screen deterioration due to sunburn *

  The UV-cut film suppresses UV rays from outside light or sunlight to prevent the touchscreen from deteriorating or browning due to sunburn. The film has a two-layered structure with a UV-cut layer and a UV-absorbing layer that blocks UV rays from inside and outside. It is ideal for use in semi-outdoor or indoor environments near windows where the sun shines in the west and for handy terminals that are carried outdoors.

• Types of Ultraviolet

  Type	Wavelength (distance)	Characteristics
  UVA	Long-wavelength UV (320 - 400nm)	Light reaching the surface of the earth.
  UVB	Medium-Wavelength Ultraviolet (280 - 320nm)	Some of the light that reaches the earth's surface. Most is absorbed by the ozone layer.
  UVA	Medium-Wavelength Ultraviolet (100 - 280nm)	Does not reach the surface and is absorbed by the ozone layer.

* For environments and applications that are exposed to sunlight for long periods of time, consider using a Capacitive Touchscreen that is not affected by ultraviolet light, although it can reduce the impact of ultraviolet light.

• Background

  Touch panel for a POS system for a gas station to be used at an outdoor construction site. Sunburn caused by the shining sun is an issue at the installation site.

• Adopt Content

  In order to centrally manage the POS data from each station and to precisely grasp the filling volume, which varies by day of the week, time, and region, manual input by on-site staff is essential. Considering the risk of errors caused by deterioration due to sun exposure, a UV-cut film was introduced to counter the risk of errors in on-site operations, where incorrect input is not permitted. The system can now be operated with periodic replacement based on running costs.
