Electric drive element and manufacturing method thereof

Abstract

The invention discloses an electric drive element and a manufacturing method thereof. A plurality of conductive patterns are formed on one surface of a first substrate, and the first substrate is covered with a photosensitive adhesive material. Patterning the photosensitive adhesive material and forming an adhesive retaining wall at the periphery of the conductive pattern; the conductive pattern and the adhesive retaining wall are arranged in a staggered manner to define a plurality of grooves; the first substrate is provided with a groove, the groove is provided with an adhesive retaining wall, an electrically driven display material is arranged in the groove, a second substrate is bonded to the first substrate through the adhesive retaining wall, the adhesive retaining wall not only canblock fluid display materials needing to be isolated from each other, but also can bond two substrates at the same time, and then the processing steps are simplified.

Description

technical field [0001] The invention relates to an electric driving element, in particular to a flexible display and a manufacturing method thereof. Background technique [0002] Lightweight and easy to carry have always been the development trend of consumer electronics products. In view of this, flexible displays have been developed in the new generation of display technology. Due to considerations of material properties, process convenience, and cost, flexible displays mostly use plastic substrates. However, during the manufacturing process, roll-to-roll (Roll-to-Roll) continuous supply is mainly provided by rolling equipment. Plastic substrate, but this causes the plastic substrate to bear the tensile stress of the scrolling device.

AI Technical Summary

Problems solved by technology

Due to considerations of material properties, process convenience, and cost, flexible displays mostly use plastic substrates. However, during the manufacturing process, roll-to-roll (Roll-to-Roll) continuous supply is mainly provided by rolling equipment. Plastic substrate, but this causes the plastic substrate to bear the tensile stress of the scrolling device

[0003] In addition, in the forming of each layer structure on the surface of the plastic substrate and the layout of electronic components, such as the yellow light process, it is necessary to go through procedures such as material deposition, photoresist coating, exposure, development, and etching. Therefore, the plastic substrate passes through the rolling equipment. After stretching, acid / alkali solution immersion, high temperature baking, high pressure and other processes, irregular deformation gradually occurs, which leads to the problem of alignment difficulties between different patterning processes, thereby reducing the manufacturing yield of products

[0004] In addition, in the structure of the aforementioned flexible display, the barrier wall is mainly used as the isolation structure between the fluid display materials, but an additional adhesive material is still required to bond the two substrates, causing inconvenience in the manufacturing process
