Abstract

This article describes a Prevention method of sheet wave. ~~~This disclosed method is to prevent optical sheet wave by using an elastic transformation belt which absorb the thermal expansion and contraction against all directions. This method is applicable for all optical sheets including the touch panel sheet. Usage of touch panel is increasing and the share of the touch sensor on the sheet is also because it is low weight and thin thickness. As one of conventional technology, Fig-1 shows that some cuts in the border area work as s but it is effective to only border area, This conventional technology can't prevent the sh the center of the sheet. But this disclosed method can prevent the sheet wave in all area of optical sheet. 1

PROTECTION MEHTOD OF SHEET WAVE

   This article describes a Prevention method of sheet wave.
~~~This disclosed method is to prevent optical sheet wave by using an elastic
transformation belt
which absorb the thermal expansion and contraction against all directions.
This method is applicable for all optical sheets including the touch panel sheet.
Usage of touch panel is increasing and the share of the touch sensor on the sheet is also
because it is low weight and thin thickness.

As one of conventional technology, Fig-1 shows that some cuts in the border area work as s
but it is effective to only border area, This conventional technology can't prevent the sh
the center of the sheet.

But this disclosed method can prevent the sheet wave in all area of optical sheet.
