Abstract
An integrated OLED display and touch screen is made by the steps of: providing a substrate; forming a top-emitting OLED display on the substrate, the display including light blocking circuit elements extending to an edge of the substrate; providing a transparent encapsulating cover; forming a touch screen on a first side of the transparent encapsulating cover, the touch screen having light blocking circuit elements extending to a corresponding edge of the transparent encapsulating cover; locating the encapsulating cover over the substrate with a light curable adhesive located between the light blocking circuit elements of the display and the touch screen; and curing the light curable adhesive to hermetically encapsulate the OLED display.
Claims17
An integrated OLED display and touch screen, comprising:
- a) a substrate;
- b) a top-emitting OLED display formed on the substrate, the display including light blocking circuit elements extending to an edge of the substrate;
- c) a transparent, encapsulating cover adhered to the substrate by a light curable adhesive to hermetically encapsulate the OLED display inside the encapsulating cover;
- and
- d) a touch screen formed on the outside of the transparent encapsulating cover, the touch screen having light blocking circuit elements extending to a corresponding edge of the transparent encapsulating cover, wherein the light curable adhesive is located between the light blocking circuit elements of the display and the touch screen.
A method of manufacturing an integrated OLED display and touch screen, comprising the steps of:
- a) providing a substrate;
- b) forming a top-emitting OLED display on the substrate, the display including light blocking circuit elements extending to an edge of the substrate;
- c) providing a transparent encapsulating cover;
- d) forming a touch screen on a first side of the transparent encapsulating cover, the touch screen having light blocking circuit elements extending to a corresponding edge of the transparent encapsulating cover;
- e) locating the encapsulating cover over the substrate with a light curable adhesive located between the light blocking circuit elements of the display and the touch screen;
- and
- f) curing the light curable adhesive to hermetically encapsulate the OLED display by directing light onto the edges of the display.
