Abstract
The invention relates to an electronic device, a touch display screen, a touch assembly and a touch conductive film. The touch conductive film comprises a transparent base material, a conductive layer, a first electrode lead, a second electrode lead, an insulting protection layer and a bonding layer. The bonding layer is arranged to surround the edge of the insulting protection layer and is located between the edge of the insulting protection layer and the transparent base material, the edge of the insulting protection layer is attached to the transparent base material through the bonding layer, so that the adhesion between the bonding layer and the transparent base material and the adhesion between the insulting protection layer and the bonding layer are both greater than the adhesion of the insulting protection layer directly adhered to the transparent base material, and the bonding layer has a certain thickness itself. When the insulting protection layer directly adheres to the transparent base material through the bonding layer, the drawing force of the edge of the insulting protection layer is smaller than the drawing force produced by the edge of the insulting protection layer when the insulting protection layer directly adheres to the transparent base material, and the phenomenon of appearance edge shedding of the insulting protection layer can be effectively avoided.

Insulating protective layer 470 covers in the second conductive layer 440 and second electrode lead 450 surface.Specifically, insulation protection
The area of layer 470 is greater than the area of the allomeric function circuit of the second conductive layer 440 and second electrode lead 450 formation, to protect
The card protection to the second conductive layer 440 and second electrode lead 450 for the insulating protective layer 470, protection circuit is not aoxidized, and isolates water
Gas, improves the reliability of product.Insulating protective layer 470 can be formed by dielectric ink or photosensitive resin dry film.
Tack coat 480 is arranged at the first surface 411 of transparent base 410, and tack coat 480 is around insulating protective layer 470
Edge is arranged, and is located between edge and the first surface 411 of transparent base 410 of insulating protective layer 470.Insulating protective layer
470 edge is attached to the first surface 411 of transparent base 410 by tack coat 480, and tack coat 480 is used for increasing insulation guarantor
Adhesive force between sheath 470 and transparent base 410.
Interval setting between tack coat 480 and the first conductive layer 420, the second conductive layer 440.Tack coat 480 is led with first
The material of electric layer 420 is identical, and is simultaneously formed at the first surface 411 of transparent base 410 with the first conductive layer 420.Because increasing
Plus tack coat 480 identical with the first conductive layer 420 material, be transparent conductive material, and tack coat 480 do not have and conductive layer
It is connected it is possible to isolate the impact to the first conductive layer 420 for the peripheral electrostatic simultaneously, and tack coat 480 and first is conductive
Layer 420 is formed by same operation, can be with Simplified flowsheet step, improve production efficiency.

Shape, multiple coherent mass are jointly around the big rectangular shape of insulating protective layer 470.Therefore, insulating protective layer 470 is by little one by one
Rectangular-shaped coherent mass is attached on transparent base 410, when one of or when some coherent mass come off, is unlikely to affect whole
Individual insulating protective layer 470 comes off from transparent base 410.
Specific in present embodiment, tack coat 480 part is located at edge and the transparent base 410 of insulating protective layer 470
Between, remainder exposes to insulating protective layer 470.Therefore, it can be effectively isolated the impact to conductive layer for the electrostatic of periphery.When
So, in other embodiments, tack coat 480 can also be entirely located in edge and the transparent base 410 of insulating protective layer 470
Between, that is, the whole face of tack coat 480 is connected with insulating protective layer 470, increases between tack coat 480 and insulating protective layer 470
Adhesive force.
Above-mentioned touch control conductive film at least has the advantage that
By arranging the tack coat 480 around insulating protective layer 470 edge, and tack coat 480 is located at insulating protective layer 470
Edge and transparent base 410 between, the edge of insulating protective layer 470 is attached on transparent base 410 by tack coat 480,
Adhesive force between adhesive force therefore between tack coat 480 and transparent base 410, insulating protective layer 470 and tack coat 480 is equal
Adhesive force when being attached directly on transparent base 410 more than insulating protective layer 470, and tack coat 480 has necessarily itself
Thickness, when the tensile force that insulating protective layer 470 edge produces is attached directly on transparent base 410 less than insulating protective layer 470
The tensile force producing, obscission in the outline edge that can be prevented effectively from insulating protective layer 470.
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.
