Problems solved by technology

Since the above-mentioned hygroscopic resin is a physical adsorption material, if the hygroscopic resin is heated, the water molecules adsorbed in the hygroscopic resin are easily released into the interior of the element due to the heat. Therefore, this multi-layer protective structure is only suitable for Suitable for low-end products of inorganic light-emitting elements and organic light-emitting elements, not suitable for high-end products of organic light-emitting elements that require high display quality

Abstract

The invention relates to a hygroscopic protect structure of organic flaring display. The structure includes one buffer layer at least, one hygroscopic material layer and a protection layer. It covers on the display area to adsorb the hydrosphere both inner the display and penetrating the protection layer.

Description

technical field [0001] The present invention relates to a package protection structure for organic light-emitting elements, in particular to a structure applicable to active matrix type organic light-emitting displays (active matrix type organic electroluminescent display, AM-OELD) and passive matrix type organic light-emitting displays (PM-OELD). - OELD) hygroscopic protective structure. Background technique [0002] Among the flat-panel displays, although the organic light-emitting display started late, it has the advantages of self-illumination, no viewing angle limit, high response speed, power saving, full-color, simple structure, and wide operating temperature range. Gradually attract attention in the field of medium and small size portable displays. [0003] Please refer to figure 1 , figure 1 It is a schematic cross-sectional view of a conventional organic light emitting display 10 . Such as figure 1 As shown, the existing organic light emitting display 10 mainl...
