技术领域 FIELD

[0001] 本发明涉及一种触摸板,特别是涉及一种电容式触摸板。 [0001] The present invention relates to a touch panel, more particularly to a capacitive touch panel. 触控面板(Touch Panel)已大量运用于家电、通信、电子信息等产品中。 The touch panel (Touch Panel) have been widely used in home appliances, communications, electronic information and other products. 如目前广泛商用的个人数字助理(PDA)、各种家电设备、游戏输入界面等。 As it is now widely commercially available personal digital assistant (PDA), a variety of home appliances, game input interface. 通过触摸板与显示器的整合,可供使用者以手指或触控笔依照显示画面上的功能选项点选输入所欲执行的动作,并且被利用到大众系统查询工具等,以提供便民效果的操作系统。 By integrating a touch panel with the display, for a user in accordance with the finger or stylus on the screen of the operation menu to perform the desired display of the input tap, and is utilized to query the public system tools, in order to provide convenient operation effect system.

背景技术 Background technique

[0002] 现有的触控面板为在一基板表面布设感应区域,其感应区域用以感应人体的手指或感应笔的信号,以达到触控的目的。 [0002] Existing touch panel is laid on a sensing area of ​​the substrate surface, which signal induces the body to the sensing area of ​​a finger or a stylus, touch to achieve the purpose. 该感应区域所使用的材料大都采用通明导电薄膜(例如氧化铟锡ΙΤ0),使得使用者在操作时,通过触压该通明导电薄膜对该显示器上相对应画面,达到触控的功能。 The sensing area of ​​transparency material used mostly using a conductive film (e.g., indium tin oxide ΙΤ0), so that the user operation, through the contact pressure of the transparency of the conductive film corresponding to a display screen, to touch function.

[0003] 目前常采用的触控面板按照触控原理可分为电阻式、电容感应式、红外线感应式、电磁感应式、音波感应式等。 [0003] It is often used in a touch panel in accordance with the principles of the touch can be divided into resistive, capacitive, infrared, induction, electromagnetic induction type, sound wave induction and the like. 其中电容感应式触摸板的工作原理为利用排列的通明电极与人体之间的静电结合所产生的电容变化,从所产生的诱导电流来检测其触控位置的坐标。 Wherein the working principle of capacitive sensing type touch panel utilizing an electrostatic transparency between the electrode body and arranged in conjunction with a change in capacitance arising from the induction current generated by the detection coordinate of the touch position. 由于电容感应式触控面板在通光度、硬度、准确率、反应时间、触控打点寿命、操作温度、和起始力量各方面都具有较佳优势,故目前已被大量采用。 Due to capacitive sensing touch panel through the brightness, hardness, accuracy, response time, the touch RBI life, operating temperature, and aspects of the preferred starting power has advantages, it has been widely adopted.

[0004] 为了要侦测出使用者以手指或感应笔触碰于触控面板上的位置,目前已存在各种不同的电容式感应触碰感测技术。 [0004] In order to detect a user touching a finger or stylus on the position on the touch panel, has a variety of capacitive sensing touch sensing technology exist. 例如在美国专利第6970160号发明专利案公开了一种格状触控感应系统,其可应用于侦测在一触控感应面的触控位置。 For example, in U.S. Patent No. 6,970,160 discloses an invention patent case lattice touch sensing system, which can be applied to detect the touch position of a touch sensing surface. 该格状触控感应系统包括两个电容感应层,该两个电容感应层中间以一隔绝材料分隔,以形成电容效应。 The lattice comprises two capacitive touch sensing system sensing layer, the two intermediate layers separated by a capacitive sensing insulating material, to form the capacitance effect. 每一电容感应层包括依相同轴向排列的导电群组,而且两个电容感应层的轴向彼此垂直。 Each capacitive sensing layer comprises a conductive group by the same axially aligned, and the two axial capacitive sensing layers perpendicular to each other. 每一个导电群组由多个以导线连接的导电单元所组成,每一电容感应层上的导电群组电连接至对应导线,再连接至一控制电路。 Each group of a plurality of electrically conductive wires connected to the conductive units composed of electrically conducting group on each capacitor conductors connected to a corresponding sensing layer, and then connected to a control circuit. 该控制电路通过导线提供信号至两组不同轴向的导电群组,使该两个不同轴向的导电单元的交错范围产生电场,如果使用者触摸到该交错范围,就会改变感应的电容值,并依据感应电容值的变化量推算用户的触控位置。 The conductive group signal to the control circuit provides two different axes through the wire, so that the two conductive units interleave range of different axial electric field is generated, if the user touches the cross range, will change the capacitance value of the induction and the touch position of the user based on the estimated amount of change in the capacitance value of the sensing.

[0005] 台湾专利第1347545号发明专利案公开了一种电容式触摸板,其架构只需要一层电容感应层,两个轴向的导电元件置于同一层,第一轴向导电元件直接用导线连接,而第二导向导电元件则覆盖绝缘层后再用导线连接,和美国专利第6970160号发明专利案相比少了一层电容感应层,因此让触控面板更轻薄,也简化了制造程序。 [0005] Taiwan Patent No. 1347545 discloses an invention patent case capacitive touch panel, its structure requires only one capacitive sensing layer, two conductive elements disposed axially in the same layer, the first conductive element directly axially wires, and the second guide after covering the electrically conductive element is connected with a wire insulation, and U.S. Patent No. 6,970,160 patent case compared layer of less capacitive sensing layer, thus enabling the touch panel thinner, but also simplifies the manufacturing program.

[0006] 台湾专利第1430162号发明专利案公开了一种电容式触摸板,电容感应层的特征是把其中一轴向导电单元的中心挖洞,使其具有一个或多个开口,依此调整导电单元的覆盖面积与导电特性,改善多点触控时信号会互相干扰的的负触效应。 [0006] Taiwan Patent No. 1430162 discloses an invention patent case capacitive touch panel, characterized in that the capacitive sensing layer wherein an axial center conductive element digging, to have one or more openings, so adjustment negative effects when contact with the conductive area coverage properties, improved multi-touch signals interfere with each other to the conductive element. 该专利也公开了把导电单元的中心挖空,并且在挖空处加上屏蔽感应单元的方式,也可以改善负触效应。 This patent also discloses the hollowed central conductive element, and a shielding manner together with the hollowed sensing unit may be improved touch negative effects. 该专利还有公开了用导线连接屏蔽感应单元,形成屏蔽感应群组的方式,该方式通过导线连接至控制电路,该控制电路通过导线提供信号至导电群组或者屏蔽感应群组,具有改善电场分布与增加感应灵敏度的效果,然而缺点是增加导线数量以及控制电路的复杂度。 This patent also discloses a mode sensing unit connected with a wire shield, a shield sensing groups, which are connected by wires to the control circuit, the control circuitry provides a signal to the conductive shield induction group or groups, with improved wire electric field distribution and increasing sensor sensitivity, however, so the disadvantage is to increase the number of wires and a control circuit complexity.

[0007] 在美国专利第6970160号发明专利案以及台湾专利第1347545号发明专利案中,虽然皆公开了可用来感应使用者触碰触控面板的功能,但该些现有的专利技术中的导电单元都有感应电场分布不均匀与感应区域的限制。 [0007] U.S. Patent No. 6,970,160 in the case of invention patent No. 1347545, and Taiwan Patent invention patent case, although all publicly available to sense user touches the touch panel functions, but these prior art patents conductive element has an uneven distribution limiting the induction field and the sensing area. 前案的导电单元的形状不论是方形、六角形或是其他形状,感应区域都只在导电单元的边缘,当用户只接触到导电单元的中心部位时,导电单元就无法感应,因此导电单元的面积必须小于用户手指的接触面积,否则会有无法感应的区域。 Shape of the conductive element before either case square, hexagonal or other shape, only the edges of the conductive sensing area unit, only when the user access to the central portion of the conductive element, the conductive element can not be induced, so the conductive element It must be smaller than the area of ​​the contact area of ​​the user's finger, or there will not sense the region.

[0008] 台湾专利第1430162号发明专利案公开了在导电单元的中心挖洞的方式,以及在导电单元的中心挖空并且加上屏蔽感应区的方式,虽然改善了负触效应,但是只能在导电单元的边缘感应。 [0008] Taiwan Patent No. 1,430,162 is disclosed in the patent case the central conductive element burrowing manner, and hollowed out center of the conductive shield means and adding the induction zone, although the effect of improving the negative contact, but only induced in the edge of the conductive element. 该专利另外公开了提供信号给屏蔽感应群组的方法,虽然具有改善电场分布与增加感应灵敏度的效果,缺点是增加导线数量以及控制电路的复杂度,导致导线之间的信号干扰会很严重,若要应用在大尺寸的触控面板,会由于导线太多而难以实现。 This patent further discloses a method of providing a signal to the shielding induction group, although having improved electric field distribution and the effect of increasing the sensitivity of the sensor, the disadvantage is to increase the number and complexity of the control circuit wires, resulting in signal interference between conductors can be severe, To apply in large-size touch panel, due to the wire too difficult to achieve.

[0009] 因此触控面板的感应层需要改善电场分布并且不需增加导线的技术,不仅增加导电单元的感应范围,避免触控屏幕有感应不到的区域,又不需要增加额外的导线。 [0009] Thus a touch panel sensing layer needs to be improved without increasing the electric field distribution and conductor technology, not only increases the sensing range of the conductive unit, to avoid induction touch screen less than the area, and no additional wires.
