Description

Technical Field

[0001] The utility model relates to the technical field of display screens, and in particular to an electronic ink screen display device. Background Art

[0002] Electronic ink screen, also known as electronic paper display technology, is a new method and technology to innovate information display. It has the advantages of being thin and light, eye-protecting, non-reflective, low power consumption, and power-off display retention.

[0003] The structure of the electronic ink screen is composed of two substrates, which are coated with an electronic ink composed of countless tiny transparent particles. The particles are formed by many black and white particles with positive and negative charges sealed in internal liquid microcapsules. Charged particles of different colors will move in different directions due to different applied electric fields, showing a black or white effect on the surface of the display screen, which looks very similar to paper. There is no reflection phenomenon of traditional LCD display in the sun. At the same time, it only consumes power when refreshing the screen, and the picture on the screen can still be retained after turning off the power, so it is very energy-saving.

[0004] In actual use, the electronic ink between the two layers of substrates of the electronic ink screen is very sensitive to the influence of water vapor. In order to ensure the life of the module, the width of the frame glue used to encapsulate the electronic ink between the two layers of substrates is relatively wide.

[0005] The utility model with application number: CN202022619980.7 (hereinafter referred to as: prior art 1) discloses an electronic ink screen module including a cover plate, OCA and an electronic ink display screen, and the cover plate is fully bonded to the electronic ink screen through OCA glue. A circle of waterproof silicone is dotted between the edge of the electronic ink display screen and the cover plate. In the prior art, the frame glue that plays a packaging role between the upper substrate and the lower substrate generally uses double-sided tape or printed resin glue, both of which cannot achieve the expected isolation effect on water vapor. The utility model adopts the process of adding some waterproof silicone after bonding the cover plate, so that while maintaining a narrow frame, the waterproof effect is better.

[0006] In the prior art 1, the waterproof performance is improved by adding silica gel, which can achieve a good sealing effect. However, in actual use, it is found that the silica gel seals the electronic ink display after solidification. Since the silica gel is exposed to the air for a long time, it is easy to cause the silica gel layer to age and fall off. Utility Model Content

[0007] The purpose of the utility model is to provide an electronic ink screen display device, which can effectively solve the technical problem in the prior art that silicone is exposed to the air for a long time, which easily causes aging and falling off of the silicone layer, and can further improve the waterproof and water vapor effect of the electronic ink screen.

[0008] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0009] An electronic ink screen display device comprises a substrate and an electronic ink screen body bonded to the substrate by OCA glue. The utility model further comprises a sealing molding frame, wherein the sealing molding frame is fixedly bonded to the substrate to surround the electronic ink screen body.

[0010] The sealing molding frame includes a bonding portion and a blocking portion vertically connected to the bonding portion, the inner side of the blocking portion is a placement hole, and a support portion extending into the placement hole is provided on the side of the blocking portion close to the substrate, and the support portion is used to contact the electronic ink screen body, and an OCA adhesive layer is formed between the electronic ink screen body and the substrate;

[0011] Silicone is arranged between the enclosure part and the sealing molding frame, and the silicone between the enclosure part and the sealing molding frame forms a silicone sealing layer.

[0012] Among them, a guide groove is arranged on the support part, and the guide groove is used to guide the excess OCA glue to the gap between the enclosure part and the electronic ink screen body when the electronic ink screen body is bonded to the substrate through OCA glue.

[0013] Furthermore, a limited support column is arranged at a position corresponding to the inner side of the enclosure and the upper substrate in the electronic ink screen body.

[0014] Preferably, a guiding inclined surface is provided on the limiting support column.

[0015] Furthermore, the placement hole includes a first vertical portion, an inclined portion, and a second vertical portion connected in sequence, and the distance from the first vertical portion to the center position of the electronic ink screen body is greater than the distance from the second vertical portion to the center position of the electronic ink screen body.

[0016] Preferably, the upper end surface of the enclosure portion is flush with the lower substrate of the electronic ink screen body.

[0017] Furthermore, the bonding portion and the enclosure portion are an integrated structure.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] The utility model covers the electronic ink screen body by setting a sealing molding frame, which can block and encapsulate the formed silicone sealing layer, avoid aging due to long-term exposure of the formed silicone sealing layer, and avoid the risk of it falling off; more importantly, in the present application, the enclosure can not only play a role of reinforcement and sealing, but also make it more convenient during assembly. After the electronic ink screen body is bonded to the substrate by OCA glue, a gap is formed between the electronic ink screen body and the sealing molding frame, and then the gap is filled with silicone by dripping silicone, which can be formed into a silicone sealing layer after solidification, thereby improving assembly efficiency.

[0034] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0035] See also Figure 1-Figure 5 This embodiment discloses a display device, specifically an electronic ink screen display device, including a substrate 101 and an electronic ink screen body 102 bonded to the substrate 101 by OCA glue.

[0036] The sealing molding frame 103 includes a bonding portion 104 and a blocking portion 105 vertically connected to the bonding portion 104. The inner side of the blocking portion 105 is a placement hole 106. The side of the blocking portion 105 close to the substrate 101 is provided with a supporting portion 107 extending into the placement hole 106. The supporting portion 107 is used to contact the electronic ink screen body 102. The OCA glue between the electronic ink screen body 102 and the substrate 101 forms an OCA glue layer 109.

[0037] Silicone is provided between the enclosure portion 105 and the sealing molding frame 103 , and the silicone between the enclosure portion 105 and the sealing molding frame 103 forms a silicone sealing layer 108 .

[0038] The utility model surrounds the electronic ink screen body 102 by setting a sealing molding frame 103, which can block and encapsulate the formed silicone sealing layer 108, avoid the formed silicone sealing layer 108 from aging due to long-term exposure, and avoid the risk of it falling off; more importantly, in the present application, the enclosure 105 can not only play the role of reinforcement and sealing, but also make it more convenient during assembly. After the electronic ink screen body 102 is bonded to the substrate 101 by OCA glue, a gap is formed between the electronic ink screen body 102 and the sealing molding frame 103, and then the gap is filled with silicone by dripping silicone, which can be formed after solidification, thereby improving the assembly efficiency.

[0039] In some preferred embodiments, a guide groove 110 is provided on the support portion 107 , and the guide groove 110 is used to guide excess OCA glue to the gap between the enclosure portion 105 and the electronic ink screen body 102 when the electronic ink screen body 102 is bonded to the substrate 101 by OCA glue.

[0040] Such a configuration enables excess OCA glue to enter the gap through the guide groove 110 .
