Description

TECHNICAL FIELD

[0001] The present application relates to the field of intelligent fitness mirrors, in particular to an intelligent fitness mirror based on a zero bonding process. BACKGROUND

[0002] In the field of large-size touch display, the infrared touch technology uses blocking as positioning point, and its infrared lamp has a service life problem, which leads to touch failure and serious external interference, seriously affecting the use experience. The frame bonding technology of capacitive touch has a distance of > 10mm between the capacitive film and the OC, which seriously affects the viewing angle and clarity of the touch display screen due to the refraction of light in the air. The zero bonding technology of capacitive touch needs to bond the capacitive film on the surface of the liquid crystal OC glass, and uses silver capacitive film, which cannot be repaired after damage, resulting in rising costs and is not suitable for large-size touch display field.

[0003] The main problem of the display module of the fitness mirror using zero bonding technology is that the pure adhesive bonding method is prone to problems such as adhesive peeling when the environment of the display module changes, thereby reducing the display effect. If a clamping method is used for bonding between layers, the thickness of the display module will be greatly increased. Therefore, how to bond the layers of the display module without increasing the thickness of the display module has become a problem to be solved in the field of intelligent fitness mirrors. SUMMARY

[0004] The present application aims to overcome the shortcomings of the prior art that the display module using the zero bonding process has a risk of adhesive peeling off from the side of the display module, which reduces the display effect of the display module. The present application provides an intelligent fitness mirror based on a zero bonding process, which enhances the adhesion between different layers of the display module and improves the service life and yield of the zero bonding display module.

[0005] The purpose of the present application is mainly achieved by the following technical solutions:

[0006] The intelligent fitness mirror based on the zero bonding process comprises a TP layer, a transparent medium layer and a display screen layer. The transparent medium layer is located between the TP layer and the display screen layer. The TP layer, the transparent medium layer and the display screen layer overlap to form a display module. The side surface of the display module is provided with a side surface protection shell. The side surface protection shell is provided with a tensioning assembly and a negative pressure assembly. The tensioning assembly is fixed to the side surface protection shell. The negative pressure assembly is fixed to the TP layer, the transparent medium layer and the display screen layer, respectively.

[0007] The negative pressure assembly can adsorb the TP layer, the transparent medium layer and the display screen layer respectively by using negative pressure, all the connecting parts of the TP layer, the transparent medium layer and the display screen layer in the negative pressure assembly are connected, the tension assembly can pull the spacing of each connecting part of the negative pressure assembly, and the TP layer, the transparent medium layer and the display screen layer can be closely attached.

[0008] The tension assembly is used for tensioning each connecting part in the negative pressure assembly.

[0009] The zero-bonding technology adopted in the application mainly fills the non-adhesive transparent medium with a refractive index equivalent to glass between the TP and the display screen. On the one hand, there is no gap between the glass and the display screen, reducing the diffuse reflection and improving the display effect; on the other hand, because it has no viscosity, the assembly and maintenance are very simple, and the comprehensive cost is low. In the prior art, the TP, the display screen and the non-adhesive transparent medium are fixed by the adhesive on the side, and the fixing has the problems of small adhesive area and easy falling of the adhesive part, thereby causing the separation between the layers of the display module, and after the gap between the non-adhesive transparent medium and the TP and / or the display screen appears, the display effect is reduced, if the adjustment is not made in time, the touch fails, the display is unclear and the like, which greatly affects the user experience.

[0010] But since the display module is not convenient to disassemble after assembly, it is not practical to reinforce the interlayer bonding of the display module after a period of use by means of glue supplementing, at which time a new way is needed to make the interlayer bonding of the display module more effective, in the application, the interlayer bonding of the display module is realized by the combination of the negative pressure assembly and the tension assembly, since the TP layer, the transparent medium layer and the display screen layer overlap to form the display module, the negative pressure assembly and the tension assembly in the application cooperate with each other to achieve the purpose of tightening the interlayer spacing of the TP layer, the transparent medium layer and the display screen layer, the connecting parts in the application can be connected to the side surfaces of the TP layer, the transparent medium layer and the display screen layer by means of negative pressure, and the TP layer and the display screen layer can be extruded towards the transparent medium layer by means of tensioning the connecting parts, since such a way avoids the separation of the interlayers of the display module caused by the extensibility of the adhesive, and also avoids the separation of the interlayers of the display module caused by the detachment of the adhesive over time, the durability of the display module in the application is improved, and the production cost and the yield can also be better controlled, the side surface of the display module is fixed by the negative pressure effect, which can effectively avoid product damage caused by the reduction of the adhesive viscosity, the use of negative pressure will not produce chemical residues, and the stability of the connecting part in long-term use can also be restored by means of vacuumizing, which is beneficial to the maintenance of the display module, such a connecting way in the application also improves the independence between the layers of the display module, avoids the disadvantage that the entire display module must be replaced when a single layer is damaged, and reduces the maintenance cost of the display module, since the tension assembly and the negative pressure assembly act on the side surface of the display module, the size of the tension assembly and the negative pressure assembly will not exceed the thickness of the display module itself, compared with the clamping type frame, the thickness of the display module itself can be reserved, so that the product of the smart fitness mirror in the application can be thinner, thereby improving the market competitiveness; the tension assembly and the negative pressure assembly cooperate with each other in the application, effectively completing the zero-bonding processing between the layers of the display module, and avoiding the problem of unstable bonding caused by a large amount of adhesive bonding the side surfaces of the layers of the display module, and also avoiding the problem of adhesive viscosity reduction caused by time factors, while improving the independence between the layers of the display module, reducing the maintenance cost after the display module is damaged.
