触摸板touch pad

技术领域technical field

本实用新型涉及一种多任务触摸板，尤指一种同时具备电容式及电阻式触控感应接口的叠层触摸板。 The utility model relates to a multi-task touch panel, in particular to a laminated touch panel with capacitive and resistive touch sensing interfaces. the

背景技术Background technique

触摸板已被广泛应用于各项电子产品上，例如，电阻式触摸板常被配置在个人数字助理(PDA)、电子字典、手机、MP3数字播放器或卫星导航仪(GPS)等小型电子产品的屏幕上使用，而电容式触摸板则大多应用作为笔记本电脑的鼠标板、虚拟触摸按键等。 Touch panels have been widely used in various electronic products. For example, resistive touch panels are often configured in small electronic products such as personal digital assistants (PDAs), electronic dictionaries, mobile phones, MP3 digital players, or satellite navigation systems (GPS). It is used on the screen, while the capacitive touch pad is mostly used as the mouse pad of the notebook computer, virtual touch buttons, etc. the

一般电容式触摸板是由使用者的手指或导体碰触或轻滑过触摸板表面的瞬间产生一个电容效应，利用控制电路即可由电容值的变化确定手指或导体的碰触位置；由于电容式触摸板可用手指进行输入，具有输入操作便利的特点，而其输入操作不需经过触压，不会让面板有承受反复应力、变形导致损害的缺点；使用手指输入虽然非常方便，但是手指输入方式感应的准确度不高，容易产生误操作，造成使用上的的困扰。电阻式触摸板可使用笔尖进行精准的触压位置操作，因此可应用在较小的使用面积或较高精度的点位输入，尤其适合用于笔划较多或形体复杂的文字辨识的输入操作；但电阻式触摸板由触压面板的输入操作方式，会使板体内部的导电膜承受反复应力、应变导致损害，故使用寿命有限。 Generally, a capacitive touch panel produces a capacitive effect when the user's finger or conductor touches or slides lightly across the surface of the touch panel, and the touch position of the finger or conductor can be determined by the change of the capacitance value by using the control circuit; The touchpad can be used for input with fingers, which has the characteristics of convenient input operation, and its input operation does not need to go through touch pressure, which will not cause the panel to suffer repeated stress and deformation to cause damage; although it is very convenient to use finger input, the finger input method The accuracy of the induction is not high, and it is easy to cause misoperation, causing troubles in use. The resistive touchpad can use the tip of the pen to perform precise touch position operation, so it can be applied to a small use area or a high-precision point input, especially suitable for the input operation of character recognition with many strokes or complex shapes; However, the input operation mode of the touch panel of the resistive touch panel will cause the conductive film inside the panel to withstand repeated stress and strain to cause damage, so the service life is limited. the

如前述说明，常用电容式触摸板及电阻式触摸板均各具功能特色与优缺 点，因此，整合前述二种触摸板的功能与优点一直是业界努力的目标，而目前已知的手段是将现有的电容式触摸板结构与电阻式触摸板结构，二者上下叠合成一板体，这种复合触摸板虽可形成在一板体上同时具备电容式与电阻式二种触控感应效能，但因其组合结构的叠层较多，导致位于下方的电阻式触摸板的触控感应效果的敏感性与精确度降低，且因板体变得较厚重，将严重减损其光学特性，造成模糊或失真的困扰。 As mentioned above, the commonly used capacitive touch panels and resistive touch panels have their own functional characteristics and advantages and disadvantages. Therefore, integrating the functions and advantages of the aforementioned two touch panels has always been the goal of the industry, and the currently known means are The existing capacitive touch panel structure and resistive touch panel structure are stacked up and down to form a board body. Although this composite touch panel can be formed on a board body, it has both capacitive and resistive touch sensors. performance, but because of the many stacked layers of the combined structure, the sensitivity and accuracy of the touch sensing effect of the resistive touch panel located below will be reduced, and because the board becomes thicker, its optical characteristics will be seriously degraded. Trouble with blurring or distortion. the

再请参阅图5、8所示，将前述各层被依序叠接组合成一多任务触摸板，其中，X轴感应层2设置在表面层1的底表面，Y轴感应层4隔着绝缘层3与X轴感应层2叠置黏合成一体，并使Y轴感应线迹与X轴线迹之间呈正交设置，Y、X轴感应线迹上的各个电容感应单元42、22略呈矩阵状排列设置；而电阻感应层5设置在基板6的上表面，并利用设在面板周缘部位的绝缘胶54与Y轴感应层4的底面黏合成一体，且在Y轴感应层4与电阻感应层5之间由该间隔球51，以将彼此分开成一定间隙而对向配置。 Referring again to Fig. 5 and shown in Fig. 8, the aforementioned layers are sequentially stacked and combined into a multi-tasking touch panel, wherein theX-axis sensing layer 2 is arranged on the bottom surface of thesurface layer 1, and the Y-axis sensing layer 4 is separated Theinsulating layer 3 and theX-axis sensing layer 2 are stacked and bonded together, and the Y-axis sensing trace and the X-axis trace are arranged orthogonally.

The sensitivity and accuracy of the touch sensing effect of the panel are improved, and the thickness of the panel body is reduced at the same time, so as to enhance the transparency of the overall touch panel and facilitate viewing. the

再如图2所示是本实用新型的另一实施例，其整体结构略是与前述实施例相同，主要差异是在Y轴感应层4与电阻感应层5之间增设一绝缘阻隔层8及一上方电阻感应层9；该绝缘阻隔层8为一可弯曲、高透光率的绝缘薄层，例如聚酯薄板或油墨薄膜；该上方电阻感应层9是一设有电子节点的透明导 电膜，且在四周缘分别电接于设在面板边缘的信号线路93；该上方电阻感应层9设置在绝缘阻隔层8的底表面，并利用设在面板周缘部位的绝缘胶54与位在下方的电阻感应层5黏合成一体，且在上方电阻感应层9与电阻感应层5之间由该间隔球51，以将彼此分开成一定间隙而对向配置。依前述构件组成的多任务触摸板，其X轴感应层2与Y轴感应层4共同构成一电容式触控感应回路，而上方电阻感应层9与电阻感应层5共同构成一电阻式触控感应回路，因此可在同一板体上同时兼具有电容式与电阻式触控感应效能。而由上述变更设置也能达成与上一实施例同样的或类似的效能，故其它相同部份在此不再赘述。 As shown in Fig. 2 again, it is another embodiment of the present utility model, and its overall structure is slightly the same as the foregoing embodiment, and the main difference is that an insulating barrier layer 8 is added between the Y-axis sensing layer 4 and theresistance sensing layer 5. An upperresistance sensing layer 9; the insulating barrier layer 8 is a flexible, high-transmittance insulating thin layer, such as a polyester sheet or ink film; the upperresistance sensing layer 9 is a transparent conductive layer with electronic nodes film, and are respectively electrically connected to thesignal lines 93 arranged on the edge of the panel at the four edges; Theresistance sensing layer 5 is bonded into one body, and thespacer ball 51 is arranged between the upperresistance sensing layer 9 and theresistance sensing layer 5 to separate each other into a certain gap and face to face. According to the multi-tasking touch panel composed of the aforementioned components, theX-axis sensing layer 2 and the Y-axis sensing layer 4 jointly form a capacitive touch sensing circuit, and the upperresistive sensing layer 9 and theresistive sensing layer 5 jointly form a resistive touch sensing circuit. Inductive circuit, so it can have both capacitive and resistive touch sensing performance on the same board.
