触控电极层及显示面板 Touch electrode layer and display panel

【技术领域】【Technical field】

本发明是有关于一种触控电极层以及显示面板，且特别是有关于一种可降低触控电极层与显示面板内的电极层之间的寄生电容的触控电极层以及具有此触控电极层的显示面板。 The present invention relates to a touch electrode layer and a display panel, and in particular to a touch electrode layer capable of reducing the parasitic capacitance between the touch electrode layer and the electrode layer in the display panel, and a touch electrode layer with the touch control electrode layer. The electrode layer of the display panel. the

【背景技术】【Background technique】

一般现有的触控显示面板，其若以触控功能的设计原理分类大致分为电容式、电阻式以及感光式等。若以触控功能的结构分类则可分为外贴式及内嵌式两种。电容式触控显示面板因具有较高的开口率及较好的讯噪比，故成为目前市面上主流新开发的趋势。而内嵌式触控显示面板的厚度又比外贴式触控显示面板更为轻薄，所以，基于上述原因，内嵌式的电容触控显示面板的原理设计可望达到更好的规格及表现。 Generally, existing touch display panels can be roughly classified into capacitive, resistive, and photosensitive types based on the design principle of the touch function. According to the structural classification of the touch function, it can be divided into two types: external sticker type and built-in type. Capacitive touch display panels have become a mainstream new development trend in the market due to their higher aperture ratio and better signal-to-noise ratio. The thickness of the in-cell touch display panel is thinner than that of the external touch display panel. Therefore, based on the above reasons, the principle design of the in-cell capacitive touch display panel is expected to achieve better specifications and performance. . the

图1绘示为现有的液晶显示面板的剖面示意图。请参照图1，现有的液晶显示面板100包括第一基板102、画素数组(pixel array)103、液晶层(LiquidCrystal，LC)104、氧化铟锡(ITO)电极膜105以及第二基板108。画素数组103配置于第一基板102上，电极膜105位于第二基板108上，而液晶显示介质104则介于第一基板102和第二基板108之间。 FIG. 1 is a schematic cross-sectional view of a conventional liquid crystal display panel. Referring to FIG. 1 , a conventional liquidcrystal display panel 100 includes afirst substrate 102 , a pixel array (pixel array) 103 , a liquid crystal layer (Liquid Crystal, LC) 104 , an indium tin oxide (ITO)electrode film 105 and asecond substrate 108 . Thepixel array 103 is disposed on thefirst substrate 102 , theelectrode film 105 is disposed on thesecond substrate 108 , and the liquidcrystal display medium 104 is interposed between thefirst substrate 102 and thesecond substrate 108 . the

就现有的内嵌式电容触控显示面板而言，电容式触控电极内嵌于液晶显示面板100的位置主要有两个：其分别为图1中的位置a或位置b。 As far as the existing in-cell capacitive touch display panel is concerned, there are mainly two positions where the capacitive touch electrodes are embedded in the liquid crystal display panel 100 : they are position a or position b in FIG. 1 . the

然而，随着消费性电子产品的轻薄短小发展趋势，液晶显示面板在使用上有了玻璃薄化的需求。所以当电容式触控电极内嵌于图1的位置a时，液晶显示面板会因为玻璃的薄化，而增加触控电极与电极膜105间的寄生电容。如此一来，将使得触控功能的扫瞄信号与液晶显示面板本身的驱动信号互相干扰 (coupling)，进而导致显示功能和触控功能的信号错误。另外，当电容式触控电极内嵌于位置b时，液晶显示面板会因为触控电极跟电极膜105之间距离的更加靠近，而产生更大的寄生电容，因而导致信号干扰情况更为严重。 However, with the development trend of thinner, lighter and smaller consumer electronic products, there is a demand for glass thinning in the use of liquid crystal display panels. Therefore, when the capacitive touch electrodes are embedded in the position a in FIG. 1 , the liquid crystal display panel will increase the parasitic capacitance between the touch electrodes and theelectrode film 105 due to the thinning of the glass. In this way, the scanning signal of the touch function and the driving signal of the liquid crystal display panel will interfere with each other (coupling), thereby causing signal errors of the display function and the touch function. In addition, when the capacitive touch electrodes are embedded in the position b, the liquid crystal display panel will generate larger parasitic capacitance due to the closer distance between the touch electrodes and theelectrode film 105 , thus causing more serious signal interference. . the

In one embodiment, theprotective layer 105 has a thickness ranging from 10 to 50 microns

, preferably 20 µm

另外，在本实施例中，每一第一上层触控电极图案300a、每一第一下层遮蔽电极图案300b、每一第二上层触控电极图案303a或每一第二下层遮蔽电极图案303b的面积为一单位触控面积307的1/2～2/3。一般而言，一个单位触控面积307大约为0.5cm×0.5cm，其相当于一个手指头的大小。上述触控电极图案300a、303a的面积的设计主要是为了能够精确的辨识出触控位置，详细说明如下： In addition, in this embodiment, each first upper layertouch electrode pattern 300a, each first lower layer shieldingelectrode pattern 300b, each second upper layertouch electrode pattern 303a or each second lower layer shieldingelectrode pattern 303b The area is 1/2˜2/3 of aunit touch area 307 . Generally speaking, aunit touch area 307 is approximately 0.5 cm×0.5 cm, which is equivalent to the size of a finger. The design of the area of thetouch electrode patterns 300a and 303a above is mainly to accurately identify the touch position, and the details are as follows:

请继续参照图3，以下以坐标位置(X_n，Y_n)来定义第二上层触控电极图案303a与第一下层遮蔽电极图案300b的重叠位置以及第一上层触控电极图案300a与第二下层遮蔽电极图案303b的重叠位置，也就是定义触控单元304、305的位置。举例而言，当手指接触到坐标位置(X_n+2，Y_n-1)时，由于第二下层遮蔽电极图案303b被第一上层触控电极图案300a所遮挡，因而在坐标位置Y_n-1的第二下层遮蔽电极图案303b无法感应到手指的触控，因而其造成X坐标无法判断。故X坐标必须由靠邻近的坐标位置(X_n+1，Y_n-1)或坐标位置(X_n+3，Y_n-1)上的第二上层触控电极303a与手指间引发的感应电容来判断。因此，为避免触控电极图案某一方向没有感应位置的效果，每一个触控电极的尺寸不能太大，因此，触控电极层的触控电极图案的面积较佳的是单位触控面积307的1/2～2/3。 Please continue to refer to FIG. 3 , the overlapping position of the second upper layertouch electrode pattern 303a and the first lower layer shieldingelectrode pattern 300b and the overlap position between the first upper layertouch electrode pattern 300a and the first lower layertouch electrode pattern 300b are defined by the coordinate position (X_n , Y_n ). The overlapping positions of the two lower-layershielding electrode patterns 303 b define the positions of thetouch units 304 and 305 . For example, when the finger touches the coordinate position (X_n+2 , Y_n-1 ), since the second lower layer shieldingelectrode pattern 303b is blocked by the first upper layertouch electrode pattern 300a, at the coordinate position Y_n- The second lowershielding electrode pattern 303b of₁ cannot sense the touch of the finger, so that the X coordinate cannot be judged. Therefore, the X coordinate must be induced by the secondupper touch electrode 303a on the adjacent coordinate position (X_n+1 , Y_n-1 ) or the coordinate position (X_n+3 , Y_n-1 ) and the finger. capacitance to judge. Therefore, in order to avoid the effect of no sensing position in a certain direction of the touch electrode pattern, the size of each touch electrode should not be too large. Therefore, the area of the touch electrode pattern on the touch electrode layer is preferably 307 per unit touch area. 1/2～2/3 of that.

以下将以立体图以及剖面图来细部说明本发明的触控电极层。图4为图3的触控电极层的局部立面放大图。请参照图3及图4，在本实施例中，第一上层触控电极图案300a与第二上层触控电极图案303a共平面，而且第一下层遮蔽电极图案300b与第二下层遮蔽电极图案303b共平面。另外，第一上层触控电极图案300a的尺寸与第二下层遮蔽电极图案303b的尺寸实质上相同，且第二上层触控电极图案的尺寸303a与第一下层遮蔽电极图案300b的尺寸实质上相同。此外，本实施例采用多个第一接触结构306以电性连接同一列的第一上层触控电极图案300a和第一下层遮蔽电极图案300b，且采用多个第二接触结构308以电性连接同一行的第二上层触控电极图案303a和第二下层遮蔽电极图案303b。在本实施例中，每一接触结构306、308为两个接触插塞。然而在其它实施例中，接触结构306、308也可以分别是一接触插塞即可，或是三个或三个以上接触插塞(如图5A所示)。此外，接触结构306、308甚至也可以是一连续接触结构，其目的是用来将下两层的电极层做电性连接，其详细整体外观可参照图5B。 The touch electrode layer of the present invention will be described in detail below with perspective views and cross-sectional views.

In addition, the size of the first upper layertouch electrode pattern 300a is substantially the same as the size of the second lower layer shieldingelectrode pattern 303b, and thesize 303a of the second upper layer touch electrode pattern is substantially the same as the size of the first lower layer shieldingelectrode pattern 300b. same. In addition, this embodiment adopts a plurality offirst contact structures 306 to electrically connect the first upper layertouch electrode pattern 300a and the first lower layer shieldingelectrode pattern 300b in the same column, and adopts a plurality ofsecond contact structures 308 to electrically connect The second upper layertouch electrode pattern 303a and the second lower layer shieldingelectrode pattern 303b in the same row are connected. In this embodiment, eachcontact structure 306, 308 is two contact plugs. However, in other embodiments, thecontact structures 306 and 308 can also be one contact plug, or three or more contact plugs (as shown in FIG. 5A ). In addition, thecontact structures 306 and 308 can even be a continuous contact structure, which is used to electrically connect the electrode layers of the lower two layers. The detailed overall appearance can refer to FIG. 5B . the

另外，图6A为沿着图3中的I₁-I₁’剖面线所示的剖面示意图，而图6B为沿着图3中的I₂-I₂’剖面线所示的剖面示意图。请参照图3以及图6A与图6B，在本实施例中，在第一上层触控电极图案300a与第二下层遮蔽电极图案303b之间更包含一层绝缘层602。在第二上层触控电极图案303a与第一下层遮蔽电极图案300b之间包含一层绝缘层602。而且当于进行触控操作时，彼此重叠的第一上层触控电极图案300a与第二下层遮蔽电极图案303b之间具有相同信号。另外，彼此重叠的第二上层触控电极图案303a与第一下层遮蔽电极图案300b间也具有相同信号。当彼此重叠的两导电层之间具有相同的电位或是电压信号时，两导电层之间即不会存在有寄生电容。本发明的触控电极层的设计方式并使重叠的两电极图案之间具有相同的电压信号，将可以降低触控电极层与电极膜之间所产生的寄生电容。 In addition, FIG. 6A is a schematic cross-sectional view along the line I₁ -I_{1 ′} in FIG. 3 , and FIG. 6B is a schematic cross-sectional view along the line I₂ -I_{2 ′} in FIG. 3 . Referring to FIG. 3 and FIGS. 6A and 6B , in this embodiment, an insulatinglayer 602 is further included between the first upper layertouch electrode pattern 300 a and the second lower layer shieldingelectrode pattern 303 b. An insulatinglayer 602 is included between the second upper layertouch electrode pattern 303a and the first lower layer shieldingelectrode pattern 300b. Moreover, when the touch operation is performed, the overlapped first upper layertouch electrode pattern 300 a and the second lower layer shieldingelectrode pattern 303 b have the same signal. In addition, the overlapping second upper layertouch electrode pattern 303 a and the first lower layer shieldingelectrode pattern 300 b also have the same signal. When the two overlapping conductive layers have the same potential or voltage signal, there will be no parasitic capacitance between the two conductive layers. The design method of the touch electrode layer of the present invention makes the two overlapping electrode patterns have the same voltage signal, which can reduce the parasitic capacitance generated between the touch electrode layer and the electrode film.

更详细而言，请参照图2、图3以及图4，为了减少触控电极层203和电极膜105间的寄生电容，本发明的第一实施例透过将第一触控电极300和第二触控电极303上下交错的排列结构，并使彼此重叠的电极图案具有相同的信号 的方式来达成。换言之，当第一上层触控电极图案300a和第二下层遮蔽电极图案303b被给一相同频率、相同大小的信号时，第一上层触控电极图案300a与第二下层遮蔽电极图案303b间会因信号的相同而不会存在有电容。而且，利用第二下层遮蔽电极图案303b可隔绝第一上层触控电极图案300a与电极膜105间的信号干扰。故此，第一上层触控电极图案300a、第二下层遮蔽电极图案303b、第二上层触控电极303a以及第一下层触控电极图案300b的面积大小相近，可对信号干扰作有效隔绝作用，并达到降低寄生电容的效果。 In more detail, please refer to FIG. 2, FIG. 3 and FIG. The twotouch electrodes 303 are arranged vertically and staggeredly, and the electrode patterns overlapping with each other have the same signal. In other words, when the first upper layertouch electrode pattern 300a and the second lower layer shieldingelectrode pattern 303b are given a signal with the same frequency and the same magnitude, there will be a gap between the first upper layertouch electrode pattern 300a and the second lower layer shieldingelectrode pattern 303b due to The signal is the same without the presence of capacitance. Moreover, signal interference between the first upper layertouch electrode pattern 300 a and theelectrode film 105 can be isolated by using the second lower layer shieldingelectrode pattern 303 b. Therefore, the areas of the first upper layertouch electrode pattern 300a, the second lower layer shieldingelectrode pattern 303b, the second upperlayer touch electrode 303a and the first lower layertouch electrode pattern 300b are similar in size, which can effectively isolate signal interference. And achieve the effect of reducing parasitic capacitance. the
