Abstract

A high malleability thin film described in the invention comprises a thin film body and an elastic unit arranged in the thin film body. When the thin film deforms due to external forces, the elastic unit deforms prior to the thin film body and can bear or absorb most of strain, and therefore the thin film will not deform greatly; the thin film can be prevented from mechanics failures, and therefore the thin film can be curled at will. A preparation method for the high malleability thin film comprises the following steps: a first step of preparing a thin film body material solution, a second step of adding the elastic unit into the thin film body material solution to obtain a mixed solution and a third step of forming the thin film from the mixed solution. The preparation method is characterized by simple steps, mature technologies, high production efficiency and low cost. By applying the preparation method for the high malleability thin film to flexible devices, the bending reliability of the devices can be effectively improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a high ductility film and its preparation method and application. Background technique [0002] The organic light-emitting display panel (English full name is OrganicLight-EmittingDisplay, referred to as OLED) has the advantages of active light emission, thinness, large viewing angle, fast response speed, energy saving, wide temperature tolerance range, flexible display and transparent display, etc. The next generation of the most potential new flat panel display technology. At the same time, the most attractive thing about organic light-emitting diodes is that they can be flexible. Specifically, organic light-emitting diodes are made on flexible polymer substrates. These polymer substrates can make organic light-emitting diodes bend and can be rolled into arbitrary shapes. [0003] Such as figure 1 As shown, in the prior art, an organic light emitting display panel is general...
