Abstract
A laminating structure of an optical clear binder (OCB) of an optical panel is applied between a display protective cover lens and a display module, or between a touch panel and the display module. The laminating structure includes two transparent low-adhesion adhesive layers and a first optical transparent sheet. One of the transparent low-adhesion adhesive layers is repeatedly removeable and directly attached to the protective cover lens or the touch panel, the other one of the transparent low-adhesion adhesive layers is repeatedly removeable and directly attached to the display module. The first optical transparent sheet is stacked between both the transparent low-adhesion adhesive layers. An upper surface of the first optical transparent sheet and a lower surface of the first optical transparent sheet are directly attached to an optical clear adhesive (OCA) layer.
