Display element stress free at the critical layer

Abstract

The invention relates to a display device, and more particularly a flexible display device comprising display component layers and display substrate such that the display remains substantially flat throughout the operating temperatures. The invention further relates a display device, and more particularly a flexible display device comprising display component layers and display substrate such that the stress in at least one layer of the light-emitting module in the display is substantially zero throughout the operating temperature range. These and other objects of the invention are accomplished by providing a flexible display, comprising at least one planar flexible substrate, at least one flexible light-emitting module deposited on the flexible substrate, the light-emitting module including at least one light-emitting layer, an anode, a cathode, and at least one top flexible superstrate on the opposite side of said display from said planar flexible substrate wherein the display is thermoelastically balanced in such a way that the display is always substantially flat, and the stress in at least one layer of the light-emitting module is substantially zero throughout the operating temperature range.
