Embodiment Construction

[0027] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below.

[0028] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected ...

Abstract

The invention relates to an electronic device and a flexible display device and the preparation method of the same. The flexible display device comprises a flexible display screen, a glue layer and a protective cover plate. The glue material is coated on the surface of the flexible display screen to form the glue layer. The glue layer comprises a colloidal component which can be cured by ultraviolet light and a non-colloidal component which cannot be cured by ultraviolet light. The glue layer is exposed by ultraviolet light through a patterned mask in the upper portion of the protective cover plate. The colloidal component is gathered in the ultraviolet light irradiation area, and the non-colloidal component is excluded from the ultraviolet light irradiation area. The colloidal component in the glue layer is cured to form a colloidal grid, and the non-colloidal component in the glue layer is filled in the colloidal grid. When the flexible display device is bent or curved, the colloidal grid in the glue layer has space to extend, which can effectively reduce the internal stress during bending. Therefore, the electronic device and a flexible display device and the preparation method of the same cannot cause the occurrence of staggered layers and can prolong the life of the flexible display device.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to an electronic device, a flexible display device and a manufacturing method thereof. Background technique [0002] Flexible display technologies based on technologies such as flexible OLED and flexible electronic paper have developed rapidly in recent years, especially flexible OLED technology, which has been widely used in many fields due to its excellent display performance. In the near future, thin and strong flexible displays that can be bent into any shape will surely replace the widely used liquid crystal displays and become the "final form" of displays. [0003] At present, flexible OLED and flexible electronic paper are used in many products, but their flexible characteristics have not been shown too much. They are usually attached under a flat protective panel or a fixed curved protective panel, and are not made into a foldable or bendable display. This is becau...
