Abstract
A touch panel module includes a display panel, a polarizing film, a first optical clear adhesive layer, a transparent touch layer, a second optical clear adhesive layer, and a protective layer that are sequentially stacked on the display panel, and a sealing adhesive layer. The first optical clear adhesive layer extends outward from an edge of the polarizing film to form a gap with the display panel. The sealing adhesive layer is formed between the display panel and the protective layer, completely covers sidewalls of the polarizing film, the first optical clear adhesive layer, the transparent touch layer, and the second optical clear adhesive layer on the same side, and fills the gap. After undergoing a temperature shock test, a number of air bubbles with a size larger than 0.1 mm per square centimeter of the touch panel module is less than 1.
