Description

Technical Field

[0001] This invention relates to the field of conductive glass technology, specifically to a double-sided anti-reflective conductive glass for touch screens. Background Technology

[0002] Capacitive touchscreens are a developing trend. Their manufacturing process primarily involves depositing a conductive film (indium tin oxide, or ITO) onto the surface of ordinary glass, thus giving it conductivity – this is conductive glass. Indium tin oxide transparent conductive film glass is a high-tech product obtained by sputtering an indium tin oxide conductive thin film onto ultra-thin glass using planar magnetron sputtering technology, followed by high-temperature annealing.

[0003] For example, Chinese patent CN106293227A discloses a processing method for double-sided anti-reflection conductive glass for touch screens. The first step is to process the upper glass substrate and the lower glass substrate. The second step is to sputter an upper transparent layer, an upper transparent passivation layer, an upper transparent layer, a lower interference layer, and a lower transparent passivation layer onto the upper glass substrate and the lower glass substrate. The third step is to sputter an upper interference layer, a lower transparent layer, and an ITO film onto the upper glass substrate and the lower glass substrate based on the sputtering in the second step.

[0004] However, the above solutions have the following shortcomings: Although the above patents can prevent the conductive glass from being etched by acid solutions during the production process, they lack protection for the finished conductive glass. Since conductive glass mainly achieves its conductive effect through indium tin oxide, and indium tin oxide has strong water absorption, when the finished conductive glass is in contact with the outside air for a long time, the indium tin oxide on the surface of the conductive glass will absorb moisture and carbon dioxide from the air and undergo a chemical reaction, resulting in deterioration and mold growth, thus making the conductive glass unusable. To address this, we have introduced a double-sided anti-reflective conductive glass for touch screens. Summary of the Invention

[0005] The purpose of this invention is to provide a double-sided anti-reflective conductive glass for touch screens to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A double-sided anti-reflective conductive glass for a touchscreen includes a glass substrate. Grooves are formed at both the upper and lower ends of the glass substrate. An ultraviolet absorption layer, an interference layer, and an indium tin oxide film layer are sequentially fixedly installed in the grooves from the inside out. Several sets of connecting cavities are formed on the outer side of the glass substrate. A slider is movably connected to each connecting cavity. A liquid storage cavity is formed within each slider. Transparent optical adhesive is placed within each liquid storage cavity. A pressure plate is movably connected within each liquid storage cavity. Two sets of springs are fixedly connected to the upper end of the pressure plate, and the other ends of the springs are fixedly connected to the liquid storage cavity.

[0008] A rubber sealing block is snapped into the groove. The end of the rubber sealing block away from the groove is fixedly connected to the connecting plate. Several sets of positioning screws are movably connected in the connecting plate. The end of the positioning screw away from the connecting plate passes through the insertion hole and extends into the connecting cavity, and contacts the slider. The insertion hole is opened in the glass substrate. A desiccant is provided in the end of the rubber sealing block near the indium tin oxide film layer.

[0009] Preferably, a T-shaped rod is fixedly connected to the lower end of the slider, the T-shaped rod slides in the limiting cavity, the limiting cavity is opened in the glass substrate, a limiting spring is fixedly connected in the limiting cavity, and the other end of the limiting spring is fixedly connected to the T-shaped rod.

[0010] Preferably, guide blocks are fixedly connected to both sides of the pressure plate, the guide blocks are slidably connected in the guide groove, and the guide groove is opened in the liquid storage cavity.

[0011] Preferably, the slider has a connecting groove, a support plate is slidably connected in the connecting groove, the upper and lower ends of the support plate are fixedly connected to the liquid storage cavity, the slider has a first drain hole on the side near the support plate, the first drain hole is connected to the liquid storage cavity, and the support plate has a clearance hole.

[0012] Preferably, a second drain hole is provided in the connecting cavity near the groove, the second drain hole is connected to the groove, and a one-way valve is fixedly connected in the second drain hole.

[0013] Preferably, locking blocks are fixedly connected to both sides of the positioning screw, and the locking blocks slide in the locking groove, which is opened in the insertion hole.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the interference layer and ultraviolet absorption layer provided below the indium tin oxide film can achieve the effect of eliminating shadows. At the same time, the sealing of the rubber sealing block and the drying of the desiccant can prevent the indium tin oxide film from contacting the outside air. When the connecting plate needs to be removed for glass substrate installation, several sets of sliders located inside the glass substrate will move upward. When the sliders move to the top of the connecting cavity, the transparent optical adhesive can be squeezed into the groove by the pressure plate, which speeds up the installation speed of the glass substrate and the glass protective screen, reduces the contact time between the indium tin oxide film and the outside air, and prevents the indium tin oxide film from becoming unusable after absorbing moisture from the air.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-5 The present invention provides a technical solution:

[0023] Example 1:

[0024] A double-sided anti-reflective conductive glass for touchscreens includes a glass substrate 1. Grooves 17 are formed at both the upper and lower ends of the glass substrate 1. From the inside to the outside, an ultraviolet absorption layer 4, an interference layer 6, and an indium tin oxide (ITO) film layer 5 are sequentially fixed and mounted in the grooves 17. Electrode patterns are etched on the ITO film layer 5. The interference layer 6 is made of niobium pentoxide, and the ultraviolet absorption layer 4 is made of titanium dioxide. The interference layer 6 is used to eliminate the etching shadows of the electrode patterns on the ITO film layer 5, resulting in a significant anti-reflective effect. The ultraviolet absorption layer 4 can absorb and refract ultraviolet light, further improving the anti-reflective effect. Furthermore, due to the presence of ITO... It has a strong water absorption capacity, so it will absorb moisture and carbon dioxide from the air and undergo a chemical reaction and deteriorate. As a result, the indium tin oxide film layer 5 may become moldy after production. Therefore, after production, the rubber sealing block 15 set in the groove 17 can isolate the indium tin oxide film layer 5 from the outside air. At the same time, a desiccant 16 is also set in the end of the rubber sealing block 15 near the indium tin oxide film layer 5. The desiccant 16 can further protect the indium tin oxide film layer 5 and prevent it from becoming moldy and affecting subsequent use.

[0025] Several sets of connecting cavities 8 are opened on the outer side of the glass substrate 1. A slider 9 is movably connected to the connecting cavity 8. A liquid storage cavity 19 is opened in the slider 9. A transparent optical adhesive is provided in the liquid storage cavity 19. A pressure plate 3 is movably connected in the liquid storage cavity 19. Two sets of springs 21 are fixedly connected to the upper end of the pressure plate 3. The other end of the springs 21 is fixedly connected to the liquid storage cavity 19. When the first drain hole 23 opened in the slider 9 moves to the position of the relief hole 26, the pressure plate 3 moves downward along the liquid storage cavity 19 under the elastic force of the spring 21 and squeezes the transparent optical adhesive in the liquid storage cavity 19. The squeezed transparent optical adhesive passes through the first drain hole 23, the relief hole 26 and the second drain hole 27 respectively and enters the groove 17. A rubber sealing block 15 is snapped in the groove 17. The end of the rubber sealing block 15 away from the groove 17 is fixedly connected to the connecting plate 14. Several sets of positioning screws 7 are movably connected in the connecting plate 14.

[0026] The end of the positioning screw 7 away from the connecting plate 14 passes through the insertion hole 28 and extends into the connecting cavity 8, contacting the slider 9. When the lower end of the positioning screw 7 leaves the upper end of the slider 9, the T-shaped rod 12 moves upward along the limiting cavity 10 under the elastic force of the limiting spring 11. The upward movement of the T-shaped rod 12 drives the slider 9 to move upward synchronously. The insertion hole 28 is opened in the glass substrate 1, allowing the lower end of the positioning screw 7 to enter the connecting cavity 8. At the same time, when the positioning screw 7 enters the connecting cavity 8, in order to ensure that the positioning screw 7 can contact the upper end of the slider 9, it can... During the insertion of the positioning screw 7 into the insertion hole 28, the locking blocks 13 located on both sides of the positioning screw 7 are ensured to be in the locking groove 18. When the locking blocks 13 are fully inserted into the locking groove 18, the positioning screw 7 is rotated to drive the two sets of locking blocks 13 to move synchronously. When the locking blocks 13 are moved away from the position in the locking groove 18, the positioning screw 7 is fixed. The rubber sealing block 15 is provided with a desiccant 16 at the end near the indium tin oxide film layer 5. The desiccant 16 can further protect the indium tin oxide film layer 5 to prevent it from becoming moldy and affecting subsequent use.

[0027] Example 2:

[0028] Based on Embodiment 1, in order to enable the slider 9 to move upward after the positioning screw 7 is disengaged from the upper end of the slider 9, and to ensure that the lens optical adhesive does not return to the liquid storage cavity 19 after entering the groove 17, a T-shaped rod 12 is fixedly connected to the lower end of the slider 9. The T-shaped rod 12 slides in the limiting cavity 10, which is opened in the glass substrate 1. A limiting spring 11 is fixedly connected in the limiting cavity 10, and the other end of the limiting spring 11 is fixedly connected to the T-shaped rod 12. When the lower end of the positioning screw 7 leaves the upper end of the slider 9, the T-shaped rod 12 moves upward along the limiting cavity 10 under the elastic force of the limiting spring 11. The upward movement of the T-shaped rod 12 drives the slider 9 to move upward synchronously.

[0029] Guide blocks 20 are fixedly connected to both sides of the pressure plate 3. The guide blocks 20 slide in the guide groove 2. The guide groove 2 is opened in the liquid storage cavity 19. When the first drain hole 23 opened in the slider 9 moves to the position of the relief hole 26, the pressure plate 3 moves downward under the elastic force of the spring 21. The movement of the pressure plate 3 drives the guide block 20 to move along the guide groove 2. Under the guiding and limiting action of the guide block 20 and the guide groove 2, the pressure plate 3 will not shake. A connecting groove 22 is opened in the slider 9. A support plate 25 slides in the connecting groove 22. The upper and lower ends of the support plate 25 are fixedly connected to the liquid storage cavity 19. A first drain hole 23 is opened in the side of the slider 9 near the support plate 25. The first drain hole 23 is connected to the liquid storage cavity 19. A relief hole 26 is opened in the support plate 25.

[0030] A second drain hole 27 is provided in the connecting cavity 8 near the groove 17. The second drain hole 27 is connected to the groove 17. A one-way valve 24 is fixedly connected in the second drain hole 27. Locking blocks 13 are fixedly connected to both sides of the positioning screw 7. The locking blocks 13 slide in the locking groove 18. The locking groove 18 is opened in the insertion hole 28. During the process of inserting the positioning screw 7 into the insertion hole 28, it is ensured that the locking blocks 13 located on both sides of the positioning screw 7 can lock in the locking groove 18. When the locking blocks 13 are fully inserted into the locking groove 18, the positioning screw 7 is rotated to drive the two sets of locking blocks 13 to move synchronously. When the locking blocks 13 are moved away from the position of entering the locking groove 18, the positioning screw 7 is limited and fixed.

[0031] Working principle: During use, when assembling conductive glass, the positioning screw 7 located in the connecting plate 14 is rotated to disengage from the locking groove 18. When the positioning screw 7 is fully rotated to the position where it can disengage from the locking groove 18, the connecting plate 14 is pulled upward to disengage the lower end of the positioning screw 7 from the connecting cavity 8. When the lower end of the positioning screw 7 leaves the upper end of the slider 9, the T-shaped rod 12 moves upward along the limiting cavity 10 under the elastic force of the limiting spring 11. The upward movement of the T-shaped rod 12 drives the slider 9 to move upward synchronously. When the first drainage hole 23 opened in the slider 9 moves to the clearance position... When the hole 26 is in position, under the elastic force of the spring 21, the pressure plate 3 moves downward along the liquid storage cavity 19 and squeezes the transparent optical adhesive set in the liquid storage cavity 19. The squeezed transparent optical adhesive passes through the first drain hole 23, the clearance hole 26 and the second drain hole 27 and enters the groove 17. At the same time, under the limiting action of the one-way valve 24, the transparent optical adhesive that has entered the groove 17 will not return to the liquid storage cavity 19. When all the transparent optical adhesive in several sets of liquid storage cavities 19 is squeezed into the groove 17, the glass insulation plate can be directly installed into the groove 17. The glass insulation plate and the glass substrate 1 can be installed together by the transparent optical adhesive.
