Description

Electronic ink screen module

Technical Field

The utility model relates to an electronic ink screen module.

Background

Electronic ink screens are also known as electronic paper. The electronic ink screen structure is composed of two substrates, an electronic ink composed of countless tiny transparent particles is coated on the electronic ink, the particles are formed by sealing a plurality of black and white particles with positive and negative electricity in an internal liquid microcapsule, the charged particles with different colors can move towards different directions due to different applied electric fields, the black or white effect is presented on the surface of the display screen, the appearance is very similar to paper, and the reflection phenomenon of the traditional liquid crystal display is avoided under the sunlight. Meanwhile, the power is consumed only when the picture is refreshed, and the picture on the display screen can be still reserved after the power is turned off, so that the power is saved. The electronic ink between the two substrates of the electronic ink screen is very sensitive to the influence of water vapor, and in order to ensure the service life of the module, the width of the frame glue used for packaging the electronic ink on the two substrates is wider. In current consumer electronics design, the main trend is narrow frames, and various display modules have the requirement of narrow frames.

Disclosure of Invention

The to-be-solved technical problem of the utility model is that not only want the electronic ink screen module have good water-proof effects when the encapsulation of electronic ink screen, but also want narrow frame.

The utility model provides an electronic ink screen module includes apron, OCA glue and electronic ink display screen, and the apron glues and the full laminating of electronic ink screen through OCA. A circle of waterproof silica gel is arranged between the edge of the electronic ink display screen and the cover plate.

The electronic ink display screen comprises a lower substrate, an electronic ink layer, an upper substrate and frame glue for connecting the upper substrate and the lower substrate, wherein the frame glue is positioned between the upper substrate and the lower substrate and positioned at the edges of the upper substrate and the lower substrate.

The upper substrate that the apron was glued through OCA and is shielded with electronic ink laminates completely, and OCA glues the size and is less than the size of the upper substrate that electronic ink shielded, and OCA glues the size dimension and contracts 0.3mm in the unilateral on the size of upper substrate.

The frame glue adopts double-sided glue or printing type resin glue;

the cover plate is made of PC, PMMA or glass.

Has the advantages that: in the prior art, the sealant for sealing between the upper substrate and the lower substrate generally uses a double-sided adhesive or a printing resin adhesive, and the two have not absolute isolation effect on water vapor, so that the width needs to be increased to enhance the waterproof property. This width is also typically a minimum of 3-4 mm. It is difficult to achieve a narrow bezel. The utility model discloses a process of some waterproof silica gel adds behind the laminating apron for when keeping narrow frame, water-proof effects is better.

Detailed Description

As shown in fig. 4, the utility model discloses an electronic ink screen module glues 6 and electronic ink display screen including apron 5, OCA, and 6 and electronic ink screen are glued through OCA to apron 5, and the point has round waterproof silica gel 9 between the edge of electronic ink display screen and the apron 5, the material of apron 5 is PC, PMMA, perhaps glass.

As shown in fig. 1 and 2, the electronic ink display screen includes a lower substrate 1, an electronic ink layer 3, an upper substrate 2, and a sealant 4 for connecting the upper substrate 2 and the lower substrate 1, wherein the sealant 4 is located between the upper substrate 2 and the lower substrate 1 and at the edges of the upper substrate 2 and the lower substrate 1. The frame glue 4 adopts double-sided glue 7 or printing type resin glue. In fig. 1, in order to make the structure of the electronic ink display screen easier to understand, gaps are drawn among the lower substrate 1, the upper substrate 2 and the electronic ink layer 3 in the figure, and there is actually no gap among the three.

The upper substrate 2 that apron 5 was glued 6 through OCA and was shielded with electronic ink is laminated entirely, and OCA glues 6 size and is less than electronic ink and shields the size of upper substrate 2, and OCA glues 6 size unilateral retraction 0.3mm on upper substrate 2's size.

The utility model discloses a packaging method of electronic ink screen module, including following step:

step 1, attaching OCA glue 6 to the surface of an upper substrate 2 of the electronic ink screen, wherein the size of the OCA glue 6 is smaller than that of the upper substrate 2, specifically, the size of the OCA glue 6 is one-sided retracted by 0.3mm in the size of the upper substrate 2.

Step 2, paste apron 5 on 6 surfaces of OCA glue, apron 5 glues 6 full laminating with OCA.

And 3, fixing a dispensing area 8, pasting a circle of double-sided adhesive tape 7 on the cover plate 5 around the electronic ink screen, and leaving a gap between the double-sided adhesive tape 7 and the electronic ink screen, wherein the gap is the dispensing area 8.

As shown in fig. 3, the thickness of double faced adhesive tape 7 is unanimous with the thickness of electron ink screen, and the laminating is back on apron 5, and the height of double faced adhesive tape 7 will be less than the 1 height of electron ink screen infrabasal plate, and the difference in height of double faced adhesive tape 7 and electron ink screen infrabasal plate 1 equals the thickness that OCA glued 6, the utility model discloses well OCA glues 6 thickness and is 0.2mm, and chooses for use the lower double faced adhesive tape 7 of viscidity, gets rid of it after the point gluing of being convenient for.

After the laminating of step 2, there is the gap between the edge of electron ink display screen and apron 5, waterproof silica gel 9 on the gap mid point, can play waterproof sealed effect. Since the silica gel 9 has fluidity, in order to prevent the glue overflow phenomenon during the dispensing, a process for fixing the dispensing region 8 is required before the dispensing.

And 4, dispensing the waterproof silica gel 9 in the dispensing area 8.

And 5, removing the double-sided adhesive tape 7.
