Touch panel and method of manufacturing the same
View Patent ↗A touch panel includes a light-transmittable upper substrate, a light-transmittable upper resistor layer on a lower surface of the upper substrate, a light-transmittable lower substrate, a light-transmittable lower resistor layer on an upper surface of the lower substrate, an adhesive layer on an upper surface of the upper substrate, and a light-transmittable plate on the adhesive layer. The upper substrate is made of material having oxygen and nitrogen removed therefrom. The lower resistor layer faces the upper resistor layer by a distance. The light-transmittable plate disables oxygen and nitrogen to pass through the plate substantively. Even being used in high temperatures, this touch panel does not produce an air bubble in the adhesive layer, hence allowing a user to clearly view a display device through the touch panel.
1. A touch panel comprising:
an upper substrate being light-transmittable and having an upper surface and a lower surface;
an upper resistor layer being light-transmittable and being provided on the lower surface of the upper substrate;
a lower substrate being light-transmittable and having an upper surface and a lower surface;
a lower resistor layer being light-transmittable and being provided on the upper surface of the lower substrate, the lower resistor layer facing the upper resistor layer by a distance;
an adhesive layer coupled to the upper surface of the upper substrate; and
a plate being light-transmittable and being provided on the adhesive layer, the plate disabling oxygen and nitrogen to pass through the plate substantively, wherein
the upper substrate is made of material having oxygen and nitrogen removed therefrom and replaced with water
the plate allows molecules of water to pass through the plate; and
the adhesive layer is provided on the upper surface of the upper substrate.
2. The touch panel according to claim 1 , wherein the plate comprises a polarizing plate.
