Problems solved by technology

Generally speaking, the substrate is made of glass or plastic material, and many organic polymer material layers above the substrate (such as display medium layer, protective layer, etc.), the Young's modulus of the polymer material layer is small and the thickness is thin, although flexible properties, but poor strain resistance
In the high-temperature process, because the thermal expansion coefficients of the substrate and the organic polymer material layer above the substrate are different, the polymer material layer is prone to warpage, which affects the subsequent processes, and causes serious stress residues, and even causes The glass substrate breaks, reducing reliability and even affecting product yield and output
In addition, in addition to using sealing glue to protect the display medium layer, an additional packaging step is required to protect the driving elements and flexible printed circuit boards on the substrate with protective glue, which cannot achieve the goal of process simplification

Abstract

The invention discloses a display apparatus comprising a substrate, a backboard, a display medium layer, a protective layer, a driving assembly, a flexible printed circuit board and sealing glue, wherein the backboard and the display medium layer are respectively arranged on the lower and upper surface of the substrate, the protective layer covers the display medium layer to prevent negative influence on the properties of the display medium layer due to penetration of environmental water or oxygen, the sealing glue encloses the side surface of the display medium layer and the protective layer and wraps the driving assembly and part of the flexible printed circuit board. Moreover, the invention also discloses a method for manufacturing the display apparatus. The display apparatus and embodiments employing said manufacturing method do no warp under high temperature processes. Moreover, the periphery of the side surfaces of the substrate and the display medium layer, the driving assembly and the flexible printed circuit board are protected by sealing glue, thereby simplifying packaging process.

Description

technical field [0001] The present invention relates to a display device and a manufacturing method thereof, and in particular to a packaging structure of a flexible display device and a manufacturing method thereof. Background technique [0002] The existing electrophoretic display device includes: a substrate (Substrate); a display medium layer (Display medium layer), as a medium for displaying images; a protective layer (Protective layer), used to block moisture or oxygen in the environment to protect the display medium layer; a sealant, used to encapsulate the side surface of the electrophoretic display device; a driving component and a flexible printed circuit board (Flexible Printed Circuit, FPC), used to drive the electrophoretic display device. After the driving element and the flexible printed circuit board are bonded to the substrate, a layer of protective glue (such as Tuffy glue) is usually applied to cover and protect the driving element and part of the flexible...
