NOVELTY - Rollable device (400) comprises rollable organic light emitting diode (OLED) (450); and rollable plastic lid laminated on rollable OLED, where plastic lid (440B) comprises single layer barrier (440A); and rollable hardcoat (440C); where rollable OLED is a rollable display or rollable lighting device. The device further comprises a display and a light source.    USE - As rollable display or rollable lighting device such as organic light emitting device (OLED), organic phototransistors, organic photovoltaic cells, and organic photodetectors, for flexible display encapsulation; used in e.g. touchscreen, flat panel display, computer monitor, medical monitor, television, billboard, general illumination device, signal, heads up display, fully transparent display, flexible display, laser printer, telephone, cell phone, personal digital assistant (PDA), laptop computer, digital camera, camcorder, viewfinder, micro-display, vehicle, large area wall, theater, stadium screen, and sign (claimed).    ADVANTAGE - The single layer barrier provides permeation protection to the OLED in the device. The protective covering provides mechanical protection to the OLED device when rolled. The protective covering and the OLED can be fabricated separately and assembled afterwards. The single layer barrier also provides a permeation barrier which protects electrodes and organic layers from damaging exposure to harmful species in the environment including moisture, vapor and/or gases.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for fabricating a rollable device involving obtaining rollable plastic lid; depositing a rollable single layer barrier on plastic lid; and laminating the rollable plastic lid with single layer barrier on rollable OLED.    DESCRIPTION OF DRAWING(S) - The figure shows schematic diagram of OLED including a barrier coated plastic lid.
