Description

电磁膜安装结构、背光显示模组及显示设备Electromagnetic film mounting structure, backlight display module and display device 技术领域Technical field
本发明涉及显示设备技术领域，特别是涉及一种电磁膜安装结构、背光显示模组及显示设备。The present invention relates to the technical field of display devices, and in particular, to an electromagnetic film mounting structure, a backlight display module, and a display device.
背景技术Background technique
在传统技术中，背光显示设备只能用作单纯的显示设备，而随着输入技术和显示技术的发展，将常用的液晶显示设备和触控装置相结合是市场的发展趋势。而且，随着市场对触控输入的体验要求的提高，如越来越追求原笔迹手写输入效果，电磁触控屏技术在背光显示设备上也获得了越来越广泛的应用。而且，在电磁触控屏技术中，需要将电磁膜设置于扩散板上。但是，电磁膜的基材一般使用的为PET(Polyethylene terephthalate，聚对苯二甲酸乙二醇酯)材料，扩散板使用的是PC(Polycarbonate，聚碳酸脂)材料，两者膨胀系数不同，从而使得在高温情况下将电磁膜贴设到扩散板上时，由于膨胀系数不同容易导致电磁膜产生褶皱，此外还容易在贴合区域形成气泡，会影响产品质量。In the traditional technology, the backlight display device can only be used as a simple display device. With the development of input technology and display technology, it is a market development trend to combine commonly used liquid crystal display devices and touch devices. In addition, with the market's increasing requirements for touch input experience, such as more and more pursuit of the original handwriting input effect, electromagnetic touch screen technology has also been more and more widely used in backlight display devices. Moreover, in the electromagnetic touch screen technology, an electromagnetic film needs to be disposed on a diffusion plate. However, PET (Polyethylene terephthalate) material is generally used as the base material of the electromagnetic film, and PC (Polycarbonate) material is used as the diffusion plate. The expansion coefficients of the two are different. When the electromagnetic film is attached to the diffusion plate under high temperature conditions, the electromagnetic film is prone to wrinkle due to different expansion coefficients, and it is also easy to form bubbles in the bonding area, which will affect the product quality.

Similarly, the ventilation holes 210 may be irregularly arranged on the second bonding film portion 204, or may be evenly arranged on the second bonding film portion 204.
此外，如图5所示，在另一些实施例中，上述电磁膜200可包括多个第二贴合膜部分204，至少一个第二贴合膜部分204上均匀开设有多个透气孔。例如，第一贴合膜部分和第二贴合膜部分均可设置为方形或多边形，而多个第二贴合 膜部分可分别连接设于一个第一贴合膜部分的多个侧边处，多个第二贴合膜部分也可以分别与多个第一贴合膜部分连接(如多个第一贴合膜部分(或第二贴合膜部分)围设形成多个框状结构，而将多个第二贴合膜部分(或第一贴合膜部分)围设在框中)。即可以在该电磁膜200上设置多个第二贴合膜部分204，对应地可设置一个或多个第一贴合膜部分，并在一个或者多个第二贴合膜部分上设置有多个透气孔210。同理，这些透气孔210可以不规则地布置在第二贴合膜部分204上，也可以均匀地布置在第二贴合膜部分202上。In addition, as shown in FIG. 5, in other embodiments, the above-mentioned electromagnetic film 200 may include a plurality of second laminated film portions 204, and at least one second laminated film portion 204 is evenly provided with a plurality of ventilation holes.

The electromagnetic film 200 is adhered to the diffusion plate 100 through the adhesive structure 300. In some embodiments, the electromagnetic film 200 may be adhered and fixed to the diffusion plate 100 by a full lamination method, that is, the diffusion plate 100 and the electromagnetic film 200 are completely adhered together in a seamless manner with water glue or optical glue. That is, the electromagnetic film 200 (including the first bonding film portion 202 and the second bonding film portion 204) can be adhered to the diffusion plate 200 by glue, and the above-mentioned adhesive structure 300 is formed after the glue is cured, so as to secure the electromagnetic film 200. Ground is attached to the diffusion plate 100. In the traditional technology, when the glue is used to stick the electromagnetic film and the diffusion plate, the glue attached to the electromagnetic film and the diffusion plate will evaporate during the curing process, but because the water molecules cannot penetrate the PET-made electromagnetic film, it will Bubbles are formed in the bonding area between the electromagnetic film and the diffusion plate. In the present application, by opening a plurality of ventilation holes 210 in the electromagnetic film 200 (the second bonding film portion 204), water molecules generated during the curing of the glue can be discharged from the ventilation holes 210, and the diffusion between the electromagnetic film 200 and the diffusion can be avoided. Bubbles are formed in the bonding area of the plate 100. Moreover, the full lamination technology can eliminate the air between the diffuser plate and the electromagnetic film, which helps reduce the reflection between the diffuser plate and the electromagnetic film, can make the electromagnetic film installation structure look more transparent, and enhance the electromagnetic film installation structure. Display effect.
此外，在另一些实施例中，电磁膜200可通过框贴的方式与扩散板100粘贴固定，即电磁膜200还可以通过双面胶粘贴固定于扩散板上。即简单的以双面胶将扩散板100与电磁膜200的四边固定，其优点在于工艺简单且成本低廉，但是在扩散板100与电磁膜200间会存在空气层。在利用双面胶粘贴电磁膜和扩散板时，也可以通过设置在电磁膜200的第二贴合膜部分204上的多个透气孔210将空气排出，避免在电磁膜200与扩散板100的贴合区域形成气泡。In addition, in other embodiments, the electromagnetic film 200 may be fixed to the diffusion plate 100 by means of a frame paste, that is, the electromagnetic film 200 may also be fixed to the diffusion plate by double-sided adhesive. That is, the four sides of the diffusion plate 100 and the electromagnetic film 200 are simply fixed by double-sided tape. The advantage is that the process is simple and the cost is low, but an air layer exists between the diffusion plate 100 and the electromagnetic film 200. When the double-sided tape is used to attach the electromagnetic film and the diffusion plate, the air can also be exhausted through the plurality of ventilation holes 210 provided in the second bonding film portion 204 of the electromagnetic film 200 to avoid the electromagnetic film 200 and the diffusion plate 100. Bubbles form in the fit area.
而且，如图1所示，在利用粘胶结构300粘贴固定扩散板100和电磁膜200时，粘胶结构300可以仅仅存在于扩散板100和电磁膜200相对的粘贴面上(例如直接用双面胶粘贴电磁膜200和扩散板100时)。此外，如图2所示，粘胶结构300还可包括粘贴于电磁膜200和扩散板100之间的粘胶主体，以及嵌入透气孔210中的粘胶凸起(例如用胶水粘贴电磁膜200和扩散板100时)。即在利用胶水对电磁膜200和扩散板100进行粘贴固定时，胶水不仅可以粘贴于电磁膜200和扩散板100相对的粘贴面上，还能渗入电磁膜200上开设的透气孔210中以形成粘胶凸起，在有效排出电磁膜200和扩散板100之间的水蒸气和空气后，还可利用粘胶凸起将透气孔210封堵住，美观大方。此外，在利用双面胶粘贴电磁膜和扩散板时，也可以使得部分的粘胶渗入到透气孔210中。Moreover, as shown in FIG. 1, when the diffusion plate 100 and the electromagnetic film 200 are fixed by using the adhesive structure 300, the adhesive structure 300 may exist only on the pasting surface of the diffusion plate 100 and the electromagnetic film 200 (for example, directly using a double (When the adhesive is applied to the electromagnetic film 200 and the diffusion plate 100). In addition, as shown in FIG. 2, the adhesive structure 300 may further include an adhesive body attached between the electromagnetic film 200 and the diffusion plate 100, and an adhesive protrusion embedded in the ventilation hole 210 (for example, the electromagnetic film 200 is pasted with glue). And diffuser plate 100). That is, when the electromagnetic film 200 and the diffusion plate 100 are fixed by using glue, the glue can not only be pasted on the pasting surface of the electromagnetic film 200 and the diffusion plate 100, but also penetrate into the ventilation holes 210 formed in the electromagnetic film 200 to form The adhesive protrusions can be used to block the ventilation holes 210 after the effective discharge of water vapor and air between the electromagnetic film 200 and the diffusion plate 100, which is beautiful and elegant. In addition, when the electromagnetic film and the diffusion plate are pasted with the double-sided adhesive, a part of the adhesive may be allowed to penetrate into the ventilation hole 210.
进一步地，粘胶凸起可嵌入部分或全部的透气孔210中，且粘胶凸起的高度值可等于或小于透气孔210的深度值。即在利用粘胶结构300粘贴电磁膜200和扩散板100时，可以使部分粘胶结构300即粘胶凸起渗入到透气孔210中，但是这些粘胶凸起不会突出到电磁膜200外，保证了电磁膜200的平整性。而且，电磁膜200的第二贴合膜部分204上的多个透气孔210中，可以使部分透气孔渗入粘胶凸起，也可以使全部的透气孔210都渗入粘胶凸起。Further, the adhesive protrusions may be embedded in some or all of the ventilation holes 210, and the height value of the adhesive protrusions may be equal to or less than the depth value of the ventilation holes 210. That is, when the electromagnetic film 200 and the diffusion plate 100 are pasted with the adhesive structure 300, a part of the adhesive structure 300, that is, the adhesive protrusions can be penetrated into the ventilation hole 210, but these adhesive protrusions will not protrude outside the electromagnetic film 200. To ensure the flatness of the electromagnetic film 200. In addition, in the plurality of ventilation holes 210 on the second bonding film portion 204 of the electromagnetic film 200, part of the ventilation holes may be penetrated into the adhesive protrusion, or all of the ventilation holes 210 may be penetrated into the adhesive protrusion.
