在本第一实施例的触控显示面板100中，磁性层15由磁性颗粒和胶水混合形成。具体的，磁性颗粒和胶水混合形成的磁性胶水，涂布在盖板14上或涂布在其他衬底膜材上，经固化后形成磁性层15。In the touch display panel 100 of the first embodiment, the magnetic layer 15 is formed by mixing magnetic particles and glue. Specifically, the magnetic glue formed by mixing magnetic particles and glue is coated on the cover plate 14 or on other substrate film materials, and the magnetic layer 15 is formed after solidification.
可选的，磁性层15直接形成在盖板14面向密封空间16的一侧。这样的设置，缩小磁性层15与触控导电层121的距离，进而提高磁性层15和触控导电层121之间的磁吸力。Optionally, the magnetic layer 15 is directly formed on the side of the cover plate 14 facing the sealed space 16. This arrangement reduces the distance between the magnetic layer 15 and the touch conductive layer 121, thereby increasing the magnetic attraction between the magnetic layer 15 and the touch conductive layer 121.
在一些实施例中，磁性层上还设置有一保护层，以避免磁性颗粒脱落。In some embodiments, a protective layer is also provided on the magnetic layer to prevent the magnetic particles from falling off.
在一些实施例中，磁性层还可以形成在盖板背离密封空间的一侧。In some embodiments, the magnetic layer may also be formed on the side of the cover plate away from the sealed space.
在本第一实施例的触控显示面板100中，磁性颗粒在磁性层中15的含量介于15%-55%之间。这样的设置，一方面确保磁性层15的光学透过率，避免影响显示面板的光学显示效果；另一方面确保磁性层15的磁力，使得磁性层15可以带动盖板14向密封空间16凹陷，使得盖板14和触控导电层121之间的间隙值变小且稳定；另外，保证磁性层15的粘附力，避免在磁吸力的作用下，盖板14和磁性层15产生分离的现象。In the touch display panel 100 of the first embodiment, the content of magnetic particles 15 in the magnetic layer is between 15% and 55%. This arrangement ensures the optical transmittance of the magnetic layer 15 on the one hand, and avoids affecting the optical display effect of the display panel; on the other hand, it ensures the magnetic force of the magnetic layer 15 so that the magnetic layer 15 can drive the cover plate 14 to dent in the sealed space 16. Make the gap between the cover 14 and the touch conductive layer 121 smaller and stable; in addition, ensure the adhesion of the magnetic layer 15 to avoid the separation of the cover 14 and the magnetic layer 15 under the action of magnetic attraction .
进一步的，磁性颗粒的粒径小于10微米，比使磁性颗粒肉眼不可见，避免影响触控显示面板100的光学显示效果。Further, the particle size of the magnetic particles is less than 10 microns, which makes the magnetic particles invisible to the naked eye and avoids affecting the optical display effect of the touch display panel 100.
在本第一实施例的触控显示面板100中，触控导电层121裸露在密封空间16内，密封空间16内填充有非氧化性气体。In the touch display panel 100 of the first embodiment, the touch conductive layer 121 is exposed in the sealed space 16, and the sealed space 16 is filled with non-oxidizing gas.
由于密封空间16内填充有非氧化性气体，且密封处理，使得触控导电层121通过密封空间16隔绝外部环境，避免触控导电层121被水汽和氧化性气体氧化，进而保护了触控导电层121。可选的，气体为氮气或惰性气体。Since the sealed space 16 is filled with non-oxidizing gas and is sealed, the touch conductive layer 121 is isolated from the external environment through the sealed space 16 to prevent the touch conductive layer 121 from being oxidized by water vapor and oxidizing gas, thereby protecting the touch conductivity Layer 121. Optionally, the gas is nitrogen or inert gas.
另外，密封空间16内的气压值小于外部环境的气压值。由于密封空间16和外部环境存在气压差异，密封空间16受力被压缩，盖板14会向密封空间16的方向凹陷。从而使得盖板14和触控导电层121之间的距离变小，进一步增加了磁性层15和触控导电层121之间的磁吸力。In addition, the air pressure value in the sealed space 16 is lower than the air pressure value of the external environment. Due to the difference in air pressure between the sealed space 16 and the external environment, the sealed space 16 is compressed by force, and the cover plate 14 will dent in the direction of the sealed space 16. As a result, the distance between the cover plate 14 and the touch conductive layer 121 is reduced, and the magnetic attraction between the magnetic layer 15 and the touch conductive layer 121 is further increased.
当然可选的，在一些实施例中，密封空间内的气压值可以等于外部环境的气压值或略大于外部环境的气压值。Of course, optionally, in some embodiments, the air pressure value in the sealed space may be equal to or slightly greater than the air pressure value of the external environment.
本第一实施例的触控显示面板100的制备过程是：The manufacturing process of the touch display panel 100 of the first embodiment is:
提供一密封的生产空间，对该生产空间抽真空处理；Provide a sealed production space and vacuumize the production space;
随后，将触控显示模组放置入该生成空间，其包括显示面板11和位于显示面板11上的触控功能层12，触控功能层12包括触控导电层121；Subsequently, the touch display module is placed into the generating space, which includes a display panel 11 and a touch function layer 12 on the display panel 11, and the touch function layer 12 includes a touch conductive layer 121;
同时，在采用涂布的方式在盖板14上直接形成磁性层15；At the same time, the magnetic layer 15 is directly formed on the cover plate 14 by coating;
最后，将盖板14设置有磁性层15的一面面向触控显示模组，进行框贴处理，以形成本第一实施例的触控显示面板100。Finally, the side of the cover plate 14 with the magnetic layer 15 facing the touch display module is subjected to frame bonding processing to form the touch display panel 100 of the first embodiment.
这样便完成了触控显示面板100的制备过程。In this way, the manufacturing process of the touch display panel 100 is completed.
请参照图2，在本第二实施例的触控显示面板200中，触控显示面板200包括显示面板21、触控功能层22、密封框23和盖板24。本第二实施例与第一实施例的不同之处在于：触控显示面板200包括一衬底层27，磁性层25形成在衬底层27上，且衬底层27和盖板24面向密封空间26的一侧贴合。2, in the touch display panel 200 of the second embodiment, the touch display panel 200 includes a display panel 21, a touch function layer 22, a sealing frame 23 and a cover plate 24. The difference between the second embodiment and the first embodiment is that the touch display panel 200 includes a substrate layer 27, the magnetic layer 25 is formed on the substrate layer 27, and the substrate layer 27 and the cover plate 24 face the sealed space 26 Fit on one side.
可选的，衬底层27可以是AG（Anti-glare）膜或钢化膜。Optionally, the substrate layer 27 may be an AG (Anti-glare) film or a toughened film.
