Detailed Description
In order that the utility model may be readily understood, a more complete description of the utility model will be rendered by reference to the appended drawings.
Referring to fig. 1 and 3, a wearable display module 10 with anti-collision effect includes: the AMOLED screen 200 comprises a cover plate 100, an AMOLED screen 200 and an anti-collision buffer structure 300, wherein the cover plate 100 is arranged on one side surface of the AMOLED screen 200; the anti-collision buffer structure 300 comprises a double-sided adhesive layer 310, a buffer foam layer 320 and an impact resistant layer 330, wherein the buffer foam layer 320 is arranged between the double-sided adhesive layer 310 and the impact resistant layer 330, and the double-sided adhesive layer 310 is attached to one side of the AMOLED screen 200 far away from the cover plate 100.
It should be noted that, the cover plate 100 and the AMOLED screen 200 are bonded and fixed by optical cement; further, the buffer foam layer 320 is made of polyurethane foam, the buffer foam layer 320 plays a role in buffering and conducting external impact force, but due to the fact that the buffer foam layer 320 is soft in material, when a product is subjected to mechanical test or daily use collision, the buffer foam layer 320 is concentrated in release of external force, so that the AMOLED screen 200 is stressed relatively greatly, the buffer foam layer 320 is limited in protection of the AMOLED screen 200, the AMOLED screen 200 is high in impact damage probability, and therefore a layer of impact resistant layer 330 is arranged on the buffer foam layer 320 far away from the AMOLED screen 200, the external impact force is effectively dispersed and conducted through the impact resistant layer 330, and the buffer and conducting of the buffer foam are combined, so that the external stress can be effectively dispersed and treated in the first time. That is, when the external force is certain, the impact layer 330 diffuses the force to avoid the concentration of the force, so that the impact of the external force to the stress of the glass local area can be reduced, thereby playing a better role in protecting the AMOLED screen 200.
In one embodiment, the double-sided adhesive layer 310 includes a first adhesive layer 311, a base material layer 312 and a second adhesive layer 313, where the first adhesive layer 311, the base material layer 312 and the second adhesive layer 313 are stacked in sequence, the first adhesive layer 311 is attached to one side of the AMOLED panel 200, and the second adhesive layer 311 is attached to the buffer foam layer 320. That is, the first adhesive layer 311 and the second adhesive layer 313 are disposed on two surfaces of the substrate layer 312, and preferably, the first adhesive layer is a pressure-sensitive adhesive layer, and the pressure-sensitive adhesive can maintain stable adhesion in high temperature, low temperature, and humidity environments, so that the adhesion stability of the crash cushion structure 300 on the AMOLED panel 200 can be well ensured, and likewise, the second adhesive layer 313 is a pressure-sensitive adhesive layer, so as to ensure the adhesion stability of the cushion foam layer 320 and the second adhesive layer 313. Further, as shown in fig. 3, a release film 314 is disposed on a side of the first adhesive layer 311 away from the substrate layer 312 to temporarily isolate and protect the first adhesive layer 311. Preferably, the substrate layer is a PET (polyester) layer.
In one embodiment, the impact resistant layer is a plastic film layer. The plastic film has certain toughness and impact strength, and the mechanical strength of the stress surface of the buffer foam layer 320 can be enhanced by adding a plastic film layer on the outermost layer of the buffer foam layer 320, so that stress is dispersed. Preferably, the plastic film layer is a PET (polyester) film layer, and since the PET film has excellent mechanical properties, toughness, better tensile strength and impact strength, when the impact force is applied, the force can be effectively dispersed and conducted by utilizing the characteristics of the PET film, and the buffer foam layer 320 is additionally used for buffering and conducting, so that the external stress can be further effectively dispersed, the damage and the breakage of the AMOLED screen 200 caused by the stress concentration are avoided, and the AMOLED screen 200 is better protected; in an embodiment, the PET film is adhered and fixed on the buffer foam layer 320 by using the adhesive 340, for example, the adhesive 340 is an organic silica gel adhesive, and the flexibility of the organic silica gel is good, so that the cracking problem of the adhesive can be avoided when the adhesive is stressed. In addition, the buffer foam layer 320 is wrapped by the PET film, so that the functions of moisture resistance and dust prevention can be achieved to a certain extent, and the AMOLED screen 200 is prevented from being wetted or polluted by dust.
Preferably, the cover plate 100 is a glass cover plate, and the glass cover plate has high transparency, so that the display effect of the display module can be ensured.
Referring to fig. 2, in another embodiment, a DLC (diamond like carbon) coating 400 is disposed on a side of the cover plate 100 away from the AMOLED screen 200, that is, a diamond-like carbon coating is formed on the surface of the cover plate 100 by vapor deposition technology, and the cover plate 100 has a better scratch-resistant effect due to a high hardness of diamond-like carbon, so that the service life of the wearable display module is prolonged.
Referring to fig. 2, in another embodiment, an anti-reflective coating layer is further disposed on a side of the cover plate 100 away from the AMOLED screen 200. Since the wearable display module is mostly required to be used outdoors, in order to avoid injury to eyes caused by strong light reflection when the wearable electronic product is used, an anti-reflection coating layer can be coated on the surface of the cover plate 100, for example, the anti-reflection coating layer comprises a silicon dioxide layer, a silicon nitride layer, a silicon dioxide layer, a niobium pentoxide layer and a niobium pentoxide layer which are stacked in sequence, so that the reflectivity of the cover plate 100 reaches 0.5%, and meanwhile, the hardness of the anti-reflection coating layer reaches 8H, so as to ensure the wear resistance of the cover plate 100.
The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the utility model, which are within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
