Problems solved by technology

Application IB 2004 / 051846 published on April 7, 2005 discloses a roll-up display which is placed in a cylindrical housing while being kept in a protective atmosphere from the air, but which is exposed in use
The protective atmosphere protects the display when the display is stored in the stick, but does not protect the display when the display is in the unfolded state
These solutions are cumbersome and offer limited protection

Embodiment Construction

[0024] In the drawings, like reference symbols generally denote like parts. Figures are not drawn to scale.

[0025] FIG. 1 shows a display screen 100 . Display screen 100 includes a substrate 101, a plurality of pixels 102, and a plurality of electrodes 103 connecting the pixels 102 to appropriate driver circuitry.

[0026] The substrate 101 may be a flexible substrate made of organic polymer or other suitable flexible materials. The substrate may for example be made of a flexible polymer material such as PET, PEN, polyurethane, polyester, polycarbonate or similar.

[0027] For the case of an active matrix array display device, the pixels 102 may include thin film transistors, which may be made of organic semiconductor materials. The transistor may be any known suitable organic semiconductor material such as polythiophene derivatives or polyphenylvinylene derivatives. A pixel has an electro-optical display element, such as an organic liquid crystal material, an organic se...

Abstract

A flexible display has barrier or other protective layers which are attached to the display only along a seam, rather than being attached to a surface of the display. The protective layers form an envelope or bag, which may have different properties on each side of the display surface and may be filled with an inert gas or inert and optically compensating liquid. The durability and lifetime of the display are increased.

Description

technical field [0001] The present invention relates to semiconductor devices made of polymer or other organic materials, and more particularly to apparatus and methods for protecting polymer electronic devices. Background technique [0002] Many electronic devices can now be made from organic materials to form bendable or even bendable or rollable devices. These materials include not only organic polymer-based flexible substrates, but also semiconductor materials such as organic light-emitting diodes (OLEDs) and organic transistors, and electro-optical materials such as electrophoretic materials. These electronic devices may in particular be display panels, which may be passive or active matrix displays. The display panel may be rollable, wherein the display panel may be coiled in successive layers at small radii, often 2 cm or less, and drawn or unrolled for use, for example, from a casing, especially a tubular casing. Other flexible display panels, if not rolled into a ...
