image
HM 20T07 NMD-C7 / -C8


APPLIES FOR THE FOLLOWING HATTELAND DISPLAY® PRODUCTS:
HM 20T07 NMD-C7 / -C8


EFFECTIVE FROM:
9 November 2010


CHANGE(S):
- Top and bottom layers of the touchscreen are held together via a double sided pressure sensitive gasket. Current gasket adhesive is replaced by a more aggressive gasket. This gasket will help to keep the top layer of the touchscreen tighter when the part is subjected to 55C temperature.

- Lamination process is modified by adding heat in order to increase the adhesive bond between the layers. This will create added adhesive bond between layers and will keep the top layer tight and prevent loosening when exposed to 55C temperature.

- Making the bond between internal touch layers stronger shall not have any impact on the qualifications. It will, increase touchscreen's strength and prevent it from puckering when exposed to high temperature.
