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.

The mask plate that side passes through patterning carries out ultraviolet photoetching to gelatine layer 200, and the colloid composition positioned at ultraviolet light area occurs
Chemical reaction and assemble, the free motion of colloid composition positioned at non-ultraviolet light area condenses together to ultraviolet light area,
By exclusion Dao ultraviolet light area outside, the colloid composition 201 in gelatine layer 200 solidify to form colloid grid to non-colloid composition 202
210, the non-colloid composition 202 in gelatine layer 200 is filled in colloid grid 210, when flexible display apparatus 10 bend or around
Qu Shi, the colloid grid 210 in gelatine layer 200 has space to be extended, and can effectively cut down the internal stress producing in bending,
Thus without the appearance causing staggered floor, extend the life-span of flexible display apparatus 10.
Above-mentioned display device, because applying above-mentioned flexible display apparatus 10, therefore similarly has flexible display apparatus 10
The advantage of the effective abatement internal stress possessing.
Embodiment described above only have expressed the several embodiments of the present invention, and its description is more concrete and detailed, but simultaneously
Can not therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
Say, without departing from the inventive concept of the premise, some deformation can also be made and improve, these broadly fall into the protection of the present invention
Scope.Therefore, the protection domain of patent of the present invention should be defined by claims.
