Description
技术领域technical field
本发明涉及触摸显示技术领域，尤其涉及一种触摸屏及触摸显示装置。The invention relates to the technical field of touch display, in particular to a touch screen and a touch display device.
背景技术Background technique
触摸屏一般安装在电子器件的显示装置上，通过检测使用者在屏幕上的触摸位置来对电子器件进行控制，如通过触摸输入信息而对显示装置显示的内容等进行控制。现有技术中常用的触摸屏包括电阻式触摸屏、电容式触摸屏以及红外线触摸屏，它们通过不同的方式获得触摸点位置信息。其中，电容式触摸屏由于具有透光率高、清晰度好、可靠性高等优点，被越来越多的应用于触摸式显示装置中。The touch screen is generally installed on the display device of the electronic device, and controls the electronic device by detecting the user's touch position on the screen, such as controlling the content displayed on the display device by touching input information. Commonly used touch screens in the prior art include resistive touch screens, capacitive touch screens, and infrared touch screens, which obtain touch point position information in different ways. Among them, the capacitive touch screen is more and more applied to touch display devices due to its advantages of high light transmittance, good definition, and high reliability.
现有的电容式触摸屏的结构可以简单地看成是由四层复合屏构成的屏体，包括：玻璃基板层、分别设于所述玻璃基板层正反两面的第一导电层和第二导电层、以及覆盖在所述第一导电层上的玻璃保护层。其中所述玻璃基板层作为基板用于在其正反两面形成所述第一导电层和第二导电层；第二导电层一面朝向触摸显示装置的显示面板一侧，用于屏蔽内部的电气信号；所述第一导电层是整个触摸屏的关键部分，用于检测触摸点的位置；所述玻璃保护层用于保护所述第一导电层，由于该玻璃保护层直接被用户长期接触，因此要求其具有较高的硬度，防止由于经常使用而被磨损，现有技术中通常采用硬度较高的矽土玻璃作为所述玻璃保护层。The structure of the existing capacitive touch screen can be simply regarded as a screen composed of a four-layer composite screen, including: a glass substrate layer, a first conductive layer and a second conductive layer respectively arranged on the front and back sides of the glass substrate layer. layer, and a protective glass layer covering the first conductive layer. Wherein the glass substrate layer is used as a substrate to form the first conductive layer and the second conductive layer on its front and back sides; one side of the second conductive layer faces the display panel side of the touch display device, and is used to shield the internal electrical signals ; The first conductive layer is a key part of the entire touch screen and is used to detect the position of the touch point; the glass protective layer is used to protect the first conductive layer. Since the glass protective layer is directly contacted by the user for a long time, it is required It has high hardness to prevent it from being worn out due to frequent use. In the prior art, silica glass with high hardness is usually used as the glass protective layer.
由上可以看出，现有的电容式触摸屏的基板层和保护层都是玻璃材质，由于玻璃具有易碎的特性，因此触摸屏摔了以后容易破裂，并且在玻璃层上打孔也比较困难；此外，由于保护层一般采用矽土玻璃保护层，需要使用到稀土材料，增加了触摸屏的成本。It can be seen from the above that the substrate layer and the protective layer of the existing capacitive touch screen are made of glass. Because the glass is fragile, the touch screen is easy to break after being dropped, and it is also difficult to punch holes in the glass layer; In addition, since the protective layer is generally made of silica glass protective layer, rare earth materials need to be used, which increases the cost of the touch screen.

本实施例中，将现有技术的玻璃基板层通过透镜基板膜实现、玻璃保护层以透明保护膜140和透明保护涂层150实现，使得整个触摸屏为全部由膜层构成的全膜结构，与现有的具有玻璃层的触摸屏相比，其具有以下优点：厚度更薄、重量更轻，使得触摸屏的便携性好；价格便宜，可以使得触摸屏的成本降低；强度提高，抗摔性好，降低维修成本，延长了触摸屏的使用寿命；在触摸屏上进行打孔等加工更加容易；不需要使用稀土材料，进一步降低成本，并且更加环保。In this embodiment, the glass substrate layer in the prior art is realized by a lens substrate film, and the glass protective layer is realized by a transparent protective film 140 and a transparent protective coating 150, so that the entire touch screen is a full-film structure composed of film layers, and Compared with the existing touch screen with glass layer, it has the following advantages: the thickness is thinner and the weight is lighter, so that the portability of the touch screen is good; the price is cheap, which can reduce the cost of the touch screen; The maintenance cost prolongs the service life of the touch screen; it is easier to perform processing such as punching on the touch screen; no need to use rare earth materials, which further reduces costs and is more environmentally friendly.
实施例二：Embodiment two:
图2所示为本实施例记载的一种电容式触摸屏200的结构示意图，如图2所示，所述触摸屏200包括：FIG. 2 is a schematic structural diagram of a capacitive touch screen 200 recorded in this embodiment. As shown in FIG. 2 , the touch screen 200 includes:
透明基板膜210，其为有机高分子聚合物材料，在本实施例中，所述透明基板膜210为聚对苯二甲酸乙二酯（Polyethyleneterephthalate，PET）材料；当然，本领域的技术人员可以知道，本发明还可以采用其它合适的材质以形成所述透明基板膜。The transparent substrate film 210 is an organic polymer material. In this embodiment, the transparent substrate film 210 is a polyethylene terephthalate (PET) material; of course, those skilled in the art can It is known that the present invention can also use other suitable materials to form the transparent substrate film.
第一导电层220，形成在所述透明基板膜210的第一面上；在本实施例中，所述第一导电层220为印刷或镀设在所述透明基板膜210第一面上的导电网层，所述导电网层由若干纵横交错的导线构成，对触摸点的坐标进行检测；The first conductive layer 220 is formed on the first surface of the transparent substrate film 210; in this embodiment, the first conductive layer 220 is printed or plated on the first surface of the transparent substrate film 210 A conductive mesh layer, the conductive mesh layer is composed of several criss-cross wires, and detects the coordinates of the touch point;
在现有技术中，由于在玻璃基板层上形成导电网层需要通过先形成金属导电膜，再通过掩膜、刻蚀等工艺将不需要的部分去除，留下的部分即为导电网层，使得在玻璃基板层上形成导电网层的工艺复杂、成本高，并且无法形成十分精细的导电网线条，因此玻璃基板层上的第一导电层220往往采用氧化铟锡（Indium Tin Oxide，ITO）透明导电薄膜；而本实施例中由于采用了透明基板膜210，通过印刷和镀膜等工艺即可在所述第一导电层220上形成网格精细的导电网层。因此，与现有技术相比，本实施例采用了导电网层作为第一导电层220之后，由于导电网层的透光率比ITO透明导电薄膜高、电阻小、信号传导速度更快更精确，因此使得整个触摸屏的透光度提高，可以做成超大面积的触摸屏；并且由于导电网层的识别精度更高，因此更加适合未来触摸屏的多触点检测以及指纹识别技术。In the prior art, since the conductive mesh layer is formed on the glass substrate layer, it is necessary to form a metal conductive film first, and then remove the unnecessary part through masking, etching and other processes, and the remaining part is the conductive mesh layer. The process of forming the conductive network layer on the glass substrate layer is complicated and costly, and it is impossible to form very fine conductive network lines. Therefore, the first conductive layer 220 on the glass substrate layer is often made of indium tin oxide (Indium Tin Oxide, ITO) A transparent conductive film; and in this embodiment, since the transparent substrate film 210 is used, a fine-grid conductive network layer can be formed on the first conductive layer 220 through processes such as printing and coating. Therefore, compared with the prior art, after this embodiment adopts the conductive mesh layer as the first conductive layer 220, since the light transmittance of the conductive mesh layer is higher than that of the ITO transparent conductive film, the resistance is small, and the signal transmission speed is faster and more accurate. , so that the light transmittance of the entire touch screen is improved, and it can be made into a large-area touch screen; and because the recognition accuracy of the conductive mesh layer is higher, it is more suitable for the multi-touch detection and fingerprint recognition technology of the future touch screen.
第二导电层230，形成在所述透明基板膜210的第二面上，，用于与所述第一导电层一起检测触摸点位置信息。在应用时，所述第二导电层230朝向触摸显示装置的显示面板设置，第一导电层220和第二导电层230的电极不停地进行电子扫描，当用户的手指或其它工具与触摸屏表面接触时，两个导电层与接触点对应位置处的电容值发生变化，控制电路根据发生变化的电容值计算出接触点位置，并作出相应的反应；在本实施例中，所述第二导电层230与第一导电层220一样，可以为印刷或镀设在所述透明基板膜210上的导电网层；The second conductive layer 230 is formed on the second surface of the transparent substrate film 210 , and is used to detect the position information of the touch point together with the first conductive layer. In application, the second conductive layer 230 is arranged towards the display panel of the touch display device, and the electrodes of the first conductive layer 220 and the second conductive layer 230 are constantly electronically scanned. When the user's finger or other tools touch the surface of the touch screen When in contact, the capacitance value at the corresponding position between the two conductive layers and the contact point changes, and the control circuit calculates the position of the contact point according to the changed capacitance value, and makes a corresponding response; in this embodiment, the second conductive layer Layer 230, like the first conductive layer 220, can be a conductive mesh layer printed or plated on the transparent substrate film 210;
透明保护膜240，与所述透明基板膜210相同的，为有机高分子聚合物材料，并且在本实施例中，所述透明保护膜240亦为PET材料，当然，本领域的技术人员可以知道，透明保护膜240的材料可以与透明基板膜210不同，与透明基板膜210类似的，本发明还可以采用其它合适的材质以形成所述透明保护膜240；The transparent protective film 240, the same as the transparent substrate film 210, is an organic polymer material, and in this embodiment, the transparent protective film 240 is also a PET material, of course, those skilled in the art can know The material of the transparent protective film 240 may be different from that of the transparent substrate film 210. Similar to the transparent substrate film 210, the present invention may also use other suitable materials to form the transparent protective film 240;
支撑膜层250，形成于所述透明保护膜240朝向第一导电层220的一侧，为透明的硬质膜层，对触摸屏起到结构性支撑作用。在本实施例中，所述支撑膜层250为聚碳酸酯(Polycarbonate，PC)膜层，当然，本领域的技术人员可以得知，除了上述的PC膜层以外，本发明的支撑膜层250还可以采用其它合适材质的透明硬质膜层来实现对触摸屏的结构性支撑。此外，如果触摸屏或显示装置的其它结构已经足够起到支撑作用，该支撑膜层250也可以省略；The supporting film layer 250 is formed on the side of the transparent protective film 240 facing the first conductive layer 220 , and is a transparent hard film layer, which plays a structural supporting role for the touch screen. In the present embodiment, the supporting film layer 250 is a polycarbonate (Polycarbonate, PC) film layer. Of course, those skilled in the art can know that, in addition to the above-mentioned PC film layer, the supporting film layer 250 of the present invention A transparent hard film layer of other suitable materials can also be used to realize structural support for the touch screen. In addition, if the touch screen or other structures of the display device are sufficient to play a supporting role, the supporting film layer 250 can also be omitted;
透明保护涂层260，通过涂覆等方式形成在所述透明保护膜240的另一侧上，用于给所述透明保护膜240表面提供大于5H的硬度，使得透明保护膜240层不易被磨损，在本实施例中，所述透明保护涂层260采用Uni-Pixel公司生产的DIAMOND GUARDTM硬化膜（HardCoat Film，其硬度为6H，足够使得本实施例的全膜式触摸屏不易磨损，提高了触摸屏使用寿命；图2中在所述支撑膜层250、透明保护膜240以及透明保护涂层260上还形成有孔290，与现有技术相比，本实施例根据需要可以更方便的打孔。The transparent protective coating 260 is formed on the other side of the transparent protective film 240 by coating, etc., and is used to provide the surface of the transparent protective film 240 with a hardness greater than 5H, so that the transparent protective film 240 layer is not easy to be worn , in the present embodiment, the transparent protective coating 260 adopts the DIAMOND GUARD TM hardened film (HardCoat Film) produced by Uni-Pixel Company, and its hardness is 6H, which is enough to make the full-film touch screen of the present embodiment not easy to wear and improve the The service life of the touch screen; in Fig. 2, holes 290 are also formed on the supporting film layer 250, the transparent protective film 240 and the transparent protective coating 260. Compared with the prior art, the present embodiment can punch holes more conveniently as required .
印刷标识层270，形成在所述支撑膜层250朝向所述第一导电层220的一侧，所述印刷标识层270的位置与对应显示面板的非显示区域对应，其作用是在触摸屏的触摸区域周围形成黑色或彩色的视窗框，商标或型号等文字或图案可以形成在该部分；在不具有支撑膜层250的方案中，该印刷标识层270也可以形成在所述透明保护膜240层朝向所述第一导电层220的一侧。由于在现有技术的玻璃保护层上形成标识层需要通过刻蚀等工艺实现，工艺复杂、成本高，并且其颜色以及形成的图案比较单一；本实施例由于采用了全膜式结构，在所述支撑膜层250或透明保护膜240上形成所述印刷标识层270时，通过印刷等简单的工艺就可以实现，降低了成本，并且可以实现复杂以及多彩的图案；The printed identification layer 270 is formed on the side of the supporting film layer 250 facing the first conductive layer 220. The position of the printed identification layer 270 corresponds to the non-display area of the corresponding display panel, and its function is to touch the touch screen. A black or colored window frame is formed around the area, and characters or patterns such as trademarks or models can be formed on this part; in the scheme without supporting film layer 250, the printed logo layer 270 can also be formed on the transparent protective film 240 layer One side facing the first conductive layer 220 . Since the formation of the marking layer on the protective glass layer of the prior art needs to be realized by etching and other processes, the process is complicated, the cost is high, and its color and the formed pattern are relatively simple; due to the adoption of the full-film structure in this embodiment, When the printed label layer 270 is formed on the support film layer 250 or the transparent protective film 240, it can be realized by a simple process such as printing, which reduces the cost, and can realize complex and colorful patterns;
