Abstract
Methods for manufacturing an ultra-thin display assembly with integrated touch functionality may include edge bonding a laminate layer to a backlight portion of an LCD module. A display portion of the LCD module may be direct bonded to a cover glass including a transparent conductive electrode layer. The cover glass may be manufactured from a large glass sheet and may have an edge polymer deposited on edges of the cover glass, a conductive polymer layer over the transparent conductive electrode layer, and a smart polymer at the edges of the cover glass.
Claims14
A method for manufacturing a display assembly for a portable information handling system, comprising:
- edge bonding a laminate cover to a rear surface of a liquid crystal display (LCD) module, wherein the laminate cover is fiber-strengthened and wherein the laminate cover forms an external surface of the portable information handling system;
- and
- direct bonding a front surface of the LCD module to a cover glass using an optically clear adhesive having a thickness E to form the display assembly, wherein the cover glass includes a transparent conductive electrode layer,
- wherein a total thickness P of the display assembly includes:
- a thickness A of the laminate cover;
- a thickness D of the LCD module;
- and
- a thickness F of the cover glass and the transparent conductive electrode layer, and
- wherein a ratio of P/A is between 10.4 and 4.4.
A method for manufacturing a cover glass assembly for an information handling system display, comprising:
- machining a cover glass portion to form a cover glass, wherein the cover glass portion is cut from a glass sheet;
- performing a chemical edge polish to chemically smooth edges of the cover glass;
- depositing an edge polymer to edge surfaces of the cover glass;
- bonding a transparent conductive layer supporting touch functionality to the cover glass;
- and
- depositing a conductive polymer layer over the transparent conductive layer at the edges of the cover glass.
