本发明涉及显示技术领域，特别是涉及一种阵列基板、触控显示面板及触控显示装置。The present invention relates to the field of display technology, in particular to an array substrate, a touch display panel and a touch display device.
背景技术Background technique
随着显示技术的飞速发展，触控显示屏已经逐渐遍及人们的生活。目前，触控显示屏按照工作原理可以分为：电阻式、电容式、红外线式、表面声波式、电磁式、振波感应式、受抑全内反射光学感应式等。其中，电容式触控显示屏以其独特的触控原理，凭借高灵敏度、长寿命、高透光率等优点，被业内普遍追捧。With the rapid development of display technologies, touch screens have gradually permeated people's lives. At present, touch screens can be divided into: resistive, capacitive, infrared, surface acoustic wave, electromagnetic, vibration induction, frustrated total internal reflection optical induction, etc. according to the working principle. Among them, the capacitive touch screen is generally sought after by the industry because of its unique touch principle, high sensitivity, long life, high light transmittance and other advantages.
目前，大多数电容式触控屏为外挂式，即触控面板与显示面板分开制作然后贴合在一起。这种技术存在制作成本较高、光透过率较低、模组较厚的缺点。随着科技的发展，内嵌式触控屏技术逐渐成为研发新宠，其是指：用于实现触控功能的触控装置设置在显示屏的基板上。采用内嵌式触控屏技术的触控显示装置相比外挂式触控显示装置，具有厚度更薄、性能更高、成本更低的优势。At present, most capacitive touch screens are plug-in, that is, the touch panel and the display panel are manufactured separately and then bonded together. This technology has the disadvantages of high production cost, low light transmittance, and thick module. With the development of science and technology, the embedded touch screen technology has gradually become a new favorite in research and development, which means that a touch device for realizing a touch function is arranged on a substrate of a display screen. Compared with the external touch display device, the touch display device adopting the embedded touch screen technology has the advantages of thinner thickness, higher performance and lower cost.
现有技术中，内嵌式触控屏主要包括互电容式触控屏和自电容式触控屏，请参考图1，图1为现有技术中一种自电容式触控屏的阵列基板，该阵列基板0100的显示区0110包括多个同层设置且相互绝缘的触控电极01，每一个触控电极01通过一条触控信号线02与驱动芯片03连接，在自电容式触控屏工作时，人的手指触控，会导致相应位置的触控电极01的电容变化，触控信号线02将触控电极01的电容变化信息传送给驱动芯片03，驱动芯片03根据电容的变化信息能够判断出用户的操作指令，从而实现触控操作。In the prior art, in-cell touch screens mainly include mutual capacitive touch screens and self-capacitive touch screens, please refer to Figure 1, Figure 1 is an array substrate of a self-capacitive touch screen in the prior art The display area 0110 of the array substrate 0100 includes a plurality of touch electrodes 01 arranged on the same layer and insulated from each other. Each touch electrode 01 is connected to the driving chip 03 through a touch signal line 02. In a self-capacitive touch screen When working, the touch of a human finger will cause the capacitance change of the touch electrode 01 at the corresponding position, and the touch signal line 02 transmits the capacitance change information of the touch electrode 01 to the driver chip 03, and the driver chip 03 according to the capacitance change information The user's operation instruction can be judged, so as to realize the touch operation.
现有技术存在的缺陷：请继续参考图1，示例性地，多个触控电极01呈阵列排布，沿靠近驱动芯片03的方向依次为第一行触控电极011、第二行触控电极012和第三行触控电极013，与第一行触控电极011中触控电极01连接的多条触控信号线02，需要与第二行触控电极012和第三行触控电极013绝缘交叠，再与驱动芯片03连接，以此类推。交叠的触控信号线02与触控电极01会产生干扰电容。如图1所示的示例，越靠近驱动芯片03的触控电极01绝缘交叠的触控信号线02越多，则产生的干扰电容越大。与驱动芯片03相邻的触控电极01受到的干扰电容最大，和与驱动芯片03距离较远的触控电极01相比，受到的干扰电容的差异较大，导致自电容式触控屏的触控精准性较差。特别的，针对长条形触控屏，触控电极的行数较多的情况下，干扰电容差异更加明显。Defects in the existing technology: Please continue to refer to Figure 1. For example, a plurality of touch electrodes 01 are arranged in an array, and the first row of touch electrodes 011 and the second row of touch electrodes The electrodes 012 and the third row of touch electrodes 013, and the multiple touch signal lines 02 connected to the touch electrodes 01 in the first row of touch electrodes 011 need to be connected with the second row of touch electrodes 012 and the third row of touch electrodes 013 is insulated and overlapped, and then connected to the driver chip 03, and so on. The overlapping touch signal lines 02 and touch electrodes 01 will generate interference capacitance. As shown in the example of FIG. 1 , the closer the touch electrode 01 to the driving chip 03 is and the more touch signal lines 02 are insulated and overlapped, the greater the generated interference capacitance will be. The touch electrode 01 adjacent to the driver chip 03 has the largest interference capacitance, and compared with the touch electrode 01 farther away from the driver chip 03, the difference in interference capacitance is larger, resulting in the self-capacitance touch screen. Touch accuracy is poor. In particular, for a strip-shaped touch screen, the difference in interference capacitance is more obvious when the number of rows of touch electrodes is large.

具体实施方式detailed description
为降低触控显示面板的触控电极受到干扰电容的差异，提高触控显示装置的触控精准性，本发明实施例提供了一种阵列基板、触控显示面板及触控显示装置。为使本发明的目的、技术方案和优点更加清楚，以下举实施例对本发明作进一步详细说明。In order to reduce the difference in the interference capacitance of the touch electrodes of the touch display panel and improve the touch accuracy of the touch display device, the embodiments of the present invention provide an array substrate, a touch display panel and a touch display device. In order to make the purpose, technical solution and advantages of the present invention clearer, the following examples are given to further describe the present invention in detail.
如图2和图3所示，本发明实施例提供的阵列基板100包括显示区110和非显示区120，显示区110设置有呈阵列排布的多个像素单元10、与多个像素单元10一一对应的薄膜晶体管11、绝缘交叉设置的多条数据线12和多条扫描线13，以及呈阵列排布的多个触控电极1，非显示区120设置有驱动芯片2，每一个触控电极1通过至少一条触控信号线3与驱动芯片2连接，其中：As shown in Figure 2 and Figure 3, the array substrate 100 provided by the embodiment of the present invention includes a display area 110 and a non-display area 120, and the display area 110 is provided with a plurality of pixel units 10 arranged in an array, and a plurality of pixel units 10 One-to-one corresponding thin film transistors 11, a plurality of data lines 12 and a plurality of scanning lines 13 arranged in an insulated intersection, and a plurality of touch electrodes 1 arranged in an array, the non-display area 120 is provided with a driver chip 2, each touch The control electrode 1 is connected to the drive chip 2 through at least one touch signal line 3, wherein:
阵列基板100在数据线12延伸方向的长度m与阵列基板100在扫描线13延伸方向的长度n的关系满足：m:n≥2:1，触控信号线3沿扫描线13延伸方向延伸至非显示区120，且沿非显示区120连接至驱动芯片2。The relationship between the length m of the array substrate 100 in the extending direction of the data lines 12 and the length n of the array substrate 100 in the extending direction of the scanning lines 13 satisfies: m:n≥2:1, and the touch signal lines 3 extend along the extending direction of the scanning lines 13 to The non-display area 120 is connected to the driver chip 2 along the non-display area 120 .
本发明实施例中，阵列基板100在数据线12延伸方向的长度m与阵列基板100在扫描线13延伸方向的长度n的关系满足：m:n≥2:1，请参考图2和图3，示例地，第一侧边130的长度与第二侧边140的长度的比值大于或等于2:1，即，阵列基板100为长条形阵列基板100。In the embodiment of the present invention, the relationship between the length m of the array substrate 100 in the extending direction of the data line 12 and the length n of the array substrate 100 in the extending direction of the scanning line 13 satisfies: m:n≥2:1, please refer to FIG. 2 and FIG. 3 For example, the ratio of the length of the first side 130 to the length of the second side 140 is greater than or equal to 2:1, that is, the array substrate 100 is an elongated array substrate 100 .
该实施例中，沿扫描线13延伸方向排列的触控电极1的数量小于沿数据线12延伸方向排列的数量，使触控信号线3沿扫描线13延伸方向延伸至非显示区120，且沿非显示区120连接至驱动芯片2。与现有技术相比，触控信号线3与触控电极1间的交叠较少，则产生的最大的干扰电容可以降低，从而可以降低触控显示面板的触控电极1受到干扰电容的差异，提高触控显示装置的触控精准性。In this embodiment, the number of touch electrodes 1 arranged along the extending direction of the scanning lines 13 is smaller than the number arranged along the extending direction of the data lines 12, so that the touch signal lines 3 extend to the non-display area 120 along the extending direction of the scanning lines 13, and It is connected to the driver chip 2 along the non-display area 120 . Compared with the prior art, the overlap between the touch signal line 3 and the touch electrode 1 is less, and the maximum interference capacitance generated can be reduced, thereby reducing the impact of the touch electrode 1 of the touch display panel on the interference capacitance. The difference improves the touch accuracy of the touch display device.
请参考图2所示的具体实施例中，触控电极1可以为自电容触控电极。在其他的实施例中，触控电极也可以为互电容触控电极1。Please refer to the specific embodiment shown in FIG. 2 , the touch electrode 1 may be a self-capacitance touch electrode. In other embodiments, the touch electrodes can also be mutual capacitance touch electrodes 1 .
请继续参考图2，触控电极1的触控信号线3分别向两侧的非显示区120延伸，即向两侧非显示区120中靠近该触控电极1的非显示区120延伸，从而进一步减少触控电极1与触控信号线3之间的交叠。示例性的，请参考图2，假如采用现有技术，与驱动芯片2相邻的触控电极1最多需要与四条触控信号线3交叠；而采用本发明的技术方案，具体采用图2所示的技术方案，触控电极1最多只需与一根触控信号线3交叠，降低了产生的最大干扰电容，从而降低触控显示面板的触控电极1受到干扰电容的差异。Please continue to refer to FIG. 2 , the touch signal lines 3 of the touch electrodes 1 respectively extend to the non-display areas 120 on both sides, that is, to the non-display areas 120 close to the touch electrodes 1 in the non-display areas 120 on both sides, so that The overlapping between the touch electrodes 1 and the touch signal lines 3 is further reduced. For example, please refer to FIG. 2 . If the existing technology is used, the touch electrodes 1 adjacent to the driver chip 2 need to overlap with four touch signal lines 3 at most; while using the technical solution of the present invention, specifically use FIG. 2 In the technical solution shown, the touch electrode 1 only needs to overlap with at most one touch signal line 3 , which reduces the maximum interference capacitance generated, thereby reducing the difference in the interference capacitance of the touch electrode 1 of the touch display panel.
请参考图4，更优的实施例中，多个像素单元10中每两行沿扫描线13设置的像素单元10为一个像素单元组14，每个像素单元组14对应一根扫描线13，扫描线13位于两行像素单元10之间且与像素单元组14的每个薄膜晶体管11连接；触控信号线3在像素单元组14之间的区域延伸至非显示区120。Please refer to FIG. 4 , in a more optimal embodiment, among the plurality of pixel units 10, every two rows of pixel units 10 arranged along the scan line 13 are a pixel unit group 14, and each pixel unit group 14 corresponds to a scan line 13, The scan line 13 is located between two rows of pixel units 10 and connected to each thin film transistor 11 of the pixel unit group 14 ; the touch signal line 3 extends to the non-display area 120 in the area between the pixel unit groups 14 .
该实施例中，每两行沿扫描线13设置的像素单元10为一个像素单元组14，每个像素单元组14对应一根扫描线13。现有技术中，每行沿扫描线13设置的像素单元10对应一条扫描线13，对于本发明实施例中的长条形阵列基板100而言，沿数据线12方向和沿扫描线13方向的分辨率相差较大，两个方向的分辨率不匹配，一般扫描线13的数量远远大于数据线12的数量，在为扫描线13充电时，由于充电时间有限，单条扫描线13容易出现充电不足的风险。本发明实施例相比现有技术，一根扫描线13同时与两行薄膜晶体管11连接，扫描线13的数量减半，则可以提高单条扫描线13的充电时间，从而降低充电不足的风险。In this embodiment, every two rows of pixel units 10 arranged along the scanning line 13 is a pixel unit group 14 , and each pixel unit group 14 corresponds to one scanning line 13 . In the prior art, each row of pixel units 10 arranged along the scanning line 13 corresponds to one scanning line 13. For the elongated array substrate 100 in the embodiment of the present invention, the pixel units along the direction of the data line 12 and along the direction of the scanning line 13 There is a large difference in resolution, and the resolutions in the two directions do not match. Generally, the number of scanning lines 13 is far greater than the number of data lines 12. When charging the scanning lines 13, due to the limited charging time, a single scanning line 13 is prone to charging. risk of inadequacy. Compared with the prior art, in the embodiment of the present invention, one scanning line 13 is connected to two rows of thin film transistors 11 at the same time, and the number of scanning lines 13 is halved, which can increase the charging time of a single scanning line 13, thereby reducing the risk of insufficient charging.
此外，该方案中，触控信号线3在像素单元组14之间的区域延伸至非显示区120，即触控信号线3设置于未设置扫描线13的区域，该方案的阵列基板100制作工艺简单，且走线时不易产生干扰。In addition, in this solution, the touch signal line 3 extends to the non-display area 120 in the area between the pixel unit groups 14, that is, the touch signal line 3 is arranged in the area where the scanning line 13 is not provided, and the array substrate 100 of this solution is manufactured The process is simple, and it is not easy to cause interference when wiring.
具体的实施例中，扫描线13与触控信号线3同层设置。通过一次工艺即可同时形成扫描线13与触控信号线3。In a specific embodiment, the scan lines 13 are arranged on the same layer as the touch signal lines 3 . The scanning lines 13 and the touch signal lines 3 can be formed simultaneously through one process.
请继续参考图4，在优选的实施例中，未设置触控信号线3的像素单元组14之间的区域设置有平行于触控信号线3的虚拟触控信号线4。该实施例中，虚拟触控信号线4无需通电，使每相邻两行的像素单元10之间均有走线，可以提高阵列基板100的均一性，从而可以提高显示面板的显示效果。Please continue to refer to FIG. 4 , in a preferred embodiment, dummy touch signal lines 4 parallel to the touch signal lines 3 are provided in the area between the pixel unit groups 14 not provided with the touch signal lines 3 . In this embodiment, the virtual touch signal lines 4 do not need to be energized, so that there are wirings between the pixel units 10 in every two adjacent rows, which can improve the uniformity of the array substrate 100 , thereby improving the display effect of the display panel.
请参考图5，优选的实施例中，阵列基板100在数据线12延伸方向的长度m与阵列基板100在扫描线13延伸方向的长度n的关系满足：m:n≥5:1。Referring to FIG. 5 , in a preferred embodiment, the relationship between the length m of the array substrate 100 in the extending direction of the data lines 12 and the length n of the array substrate 100 in the extending direction of the scanning lines 13 satisfies: m:n≥5:1.
该实施例中，第一侧边130的长度与第二侧边140的长度的比值大于或等于5:1。则阵列基板100在数据线12延伸方向设置的触控电极1的数量远远小于在扫描线13延伸方向设置的触控电极1的数量，降低触控显示面板的触控电极1受到干扰电容的差异的效果更明显，提高触控显示装置的触控精准性的幅度更大。In this embodiment, the ratio of the length of the first side 130 to the length of the second side 140 is greater than or equal to 5:1. Then the number of touch electrodes 1 arranged on the array substrate 100 in the extending direction of the data lines 12 is much smaller than the number of touch electrodes 1 arranged in the extending direction of the scanning lines 13, reducing the influence of the touch electrodes 1 of the touch display panel on interference capacitance. The effect of the difference is more obvious, and the range of improving the touch accuracy of the touch display device is greater.
请参考图6，触控电极1沿数据线12延伸方向排列形成列，阵列基板100包括两列触控电极1，且每列触控信号线3分别沿扫描线13延伸方向延伸至相邻的非显示区120。Please refer to FIG. 6 , the touch electrodes 1 are arranged in columns along the extending direction of the data lines 12 , the array substrate 100 includes two columns of touch electrodes 1 , and each column of touch signal lines 3 extends along the extending direction of the scanning lines 13 to adjacent ones. non-display area 120 .
该实施例中，触控信号线3仅仅有可能与对应的触控电极1存在交叠，产生的干扰电容较小，且每个触控信号线3在与对应的触控电极1连接时，一方面，若每个连接点与触控电极1靠近触控信号线3延伸方向的侧边的距离相同，即触控信号线3与触控电极1的交叠区域相同，则触控信号线3与触控电极间的干扰电容也相同，可以相互抵消，对触控精度的影响较小；另一方面，若连接点位于对应的触控电极1靠近触控信号线3延伸方向的侧边，则可以进一步的减小触控信号线3与对应的触控电极1产生的电容干扰。因此，该方案可以有效的解决触控信号线3与触控电极1间产生电容干扰，从而导致触控精确性较差的问题。In this embodiment, the touch signal line 3 may overlap with the corresponding touch electrode 1 only, and the generated interference capacitance is small, and when each touch signal line 3 is connected to the corresponding touch electrode 1, On the one hand, if the distance between each connection point and the side of the touch electrode 1 close to the extending direction of the touch signal line 3 is the same, that is, the overlapping area between the touch signal line 3 and the touch electrode 1 is the same, then the touch signal line 3 and the interference capacitance between the touch electrodes are also the same, which can cancel each other out and have little influence on the touch accuracy; , then the capacitive interference generated between the touch signal line 3 and the corresponding touch electrode 1 can be further reduced. Therefore, this solution can effectively solve the problem of poor touch accuracy caused by capacitive interference between the touch signal line 3 and the touch electrode 1 .
请继续参考图5，本发明另一优选实施例中，在特长条阵列基板100中，触控电极1沿数据线12延伸方向排列形成列，阵列基板100包括一列触控电极1，且相邻两个触控电极1的触控信号线3分别延伸至两侧的非显示区120。Please continue to refer to FIG. 5. In another preferred embodiment of the present invention, in the extra-long array substrate 100, the touch electrodes 1 are arranged in rows along the extending direction of the data lines 12. The array substrate 100 includes a row of touch electrodes 1, and the adjacent The touch signal lines 3 of the two touch electrodes 1 respectively extend to the non-display areas 120 on both sides.
同样地，该实施例中，触控信号线3仅仅有可能与对应的触控电极1存在交叠，产生的干扰电容较小，且每个触控信号线3在与对应的触控电极1连接时，一方面，若每个连接点与触控电极1靠近触控信号线3延伸方向的侧边的距离相同，即触控信号线3与触控电极1的交叠区域相同，则触控信号线3与触控电极间的干扰电容也相同，可以相互抵消，对触控精度的影响较小；另一方面，若连接点位于对应的触控电极1靠近触控信号线3延伸方向的侧边，则可以进一步的减小触控信号线3与对应的触控电极1产生的电容干扰。因此，该方案可以有效的解决触控信号线3与触控电极1间产生电容干扰，从而导致触控精确性较差的问题。Similarly, in this embodiment, the touch signal line 3 may only overlap with the corresponding touch electrode 1 , and the interference capacitance generated is small, and each touch signal line 3 overlaps with the corresponding touch electrode 1 When connecting, on the one hand, if the distance between each connection point and the side of the touch electrode 1 close to the extending direction of the touch signal line 3 is the same, that is, the overlapping area between the touch signal line 3 and the touch electrode 1 is the same, then the touch The interference capacitance between the control signal line 3 and the touch electrode is also the same, which can cancel each other out and has little influence on the touch accuracy; side, it can further reduce the capacitive interference between the touch signal line 3 and the corresponding touch electrode 1 . Therefore, this solution can effectively solve the problem of poor touch accuracy caused by capacitive interference between the touch signal line 3 and the touch electrode 1 .
此外，该实施例中，阵列基板100只包括一列触控电极1，相邻两个触控电极1的触控信号线3分别延伸至两侧的非显示区120，触控信号线3走线时，分别从两侧走线，两侧的非显示区120需要容纳的触控信号线3的数量有限，可以降低工艺难度。In addition, in this embodiment, the array substrate 100 only includes one row of touch electrodes 1, the touch signal lines 3 of two adjacent touch electrodes 1 respectively extend to the non-display areas 120 on both sides, and the touch signal lines 3 are routed When wiring is routed from both sides, the number of touch signal lines 3 that need to be accommodated in the non-display areas 120 on both sides is limited, which can reduce the difficulty of the process.
请参考图7，对于需要具有较大开口率的阵列基板100，例如液晶显示面板的阵列基板100，像素单元10之间的两条数据线12应该尽量靠近，对于设置有黑矩阵的阵列基板100，数据线12应该设置于上述黑矩阵对应的位置，以提高该阵列基板100的开口率。Please refer to FIG. 7, for an array substrate 100 that needs to have a larger aperture ratio, such as an array substrate 100 of a liquid crystal display panel, the two data lines 12 between the pixel units 10 should be as close as possible. For an array substrate 100 provided with a black matrix , the data line 12 should be arranged at the position corresponding to the black matrix, so as to increase the aperture ratio of the array substrate 100 .
请参考图4，对于不需要考虑开口率的阵列基板100，例如有机发光二极管显示面板的阵列基板100，数据线12可以与像素单元10交叠，数据线12可以均匀分布，从而提高阵列基板100的均一性，提高显示效果。Please refer to FIG. 4 , for an array substrate 100 that does not need to consider the aperture ratio, such as the array substrate 100 of an organic light emitting diode display panel, the data lines 12 can overlap with the pixel units 10, and the data lines 12 can be evenly distributed, thereby improving the array substrate 100. Uniformity, improve the display effect.
请参考图8，对于上述不需要考虑开口率的阵列基板100，触控信号线3可以设计的较宽。优选的，沿远离驱动芯片2的方向的触控电极1对应的触控线号线宽度逐渐增加。越远离驱动芯片2的触控电极1对应的触控信号线3越长，在宽度相同的情况下，触控信号线3越长则电阻越大，本发明实施例中，沿远离驱动芯片2的方向的触控电极1对应的触控线号线宽度逐渐增加，而长度相同的情况下，触控信号线3越宽则电阻越小。该方案将越长的触控信号线3设计的越宽，从而尽量使各个触控电极1对应的触控信号线3的电阻相同或者相接近，从而进一步提高阵列基板100触控精度和准确性。Please refer to FIG. 8 , for the above-mentioned array substrate 100 that does not need to consider the aperture ratio, the touch signal line 3 can be designed wider. Preferably, the width of the touch line corresponding to the touch electrode 1 along the direction away from the driving chip 2 gradually increases. The touch signal line 3 corresponding to the touch electrode 1 farther away from the driving chip 2 is longer. In the case of the same width, the longer the touch signal line 3 is, the greater the resistance is. The width of the touch line number corresponding to the touch electrode 1 in the direction increases gradually, and in the case of the same length, the wider the touch signal line 3 is, the smaller the resistance is. In this solution, the longer touch signal lines 3 are designed to be wider, so that the resistances of the touch signal lines 3 corresponding to each touch electrode 1 are the same or close to each other, thereby further improving the touch precision and accuracy of the array substrate 100 .
本发明实施例还提供了一种触控显示面板，该触控显示面板包括上述任一技术方案中的阵列基板。An embodiment of the present invention also provides a touch display panel, which includes the array substrate in any one of the above technical solutions.
上述阵列基板中，触控信号线沿扫描线的方向延伸至非显示区，而沿扫描线13方向排列的触控电极1的数量小于沿数据线12方向排列的数量，因此可以触控信号线3与触控电极1间的交叠较少，则产生的最大的干扰电容可以降低，从而可以降低触控显示面板的触控电极1受到干扰电容的差异，提高触控显示装置的触控精准性。In the above-mentioned array substrate, the touch signal lines extend to the non-display area along the direction of the scanning lines, and the number of touch electrodes 1 arranged along the direction of the scanning lines 13 is smaller than the number arranged along the direction of the data lines 12, so the touch signal lines can be 3 and the touch electrode 1 are less overlapped, and the maximum interference capacitance generated can be reduced, thereby reducing the difference in the interference capacitance of the touch electrode 1 of the touch display panel, and improving the touch accuracy of the touch display device sex.
可选的，触控显示面板的具体类型不限，例如，可以为液晶触控显示面板、电泳触控显示面板或者有机发光二极管触控显示面板。Optionally, the specific type of the touch display panel is not limited, for example, it may be a liquid crystal touch display panel, an electrophoretic touch display panel or an organic light emitting diode touch display panel.
请参考图9，本发明实施例还提供了一种触控显示装置200，该触控显示装置200包括上述任一技术方案中的触控显示面板300。Please refer to FIG. 9 , an embodiment of the present invention further provides a touch display device 200 , which includes the touch display panel 300 in any of the above technical solutions.
该方案中的触控显示装置200包括的触控显示面板300的触控电极1受到干扰电容的差异较小，因此触控显示装置的触控精准性较高。In this solution, the touch display device 200 includes a small difference in the interference capacitance of the touch electrodes 1 of the touch display panel 300 , so the touch control accuracy of the touch display device is relatively high.
可选的，本发明实施例中，触控显示装置的具体类型不限，可以为触控手机、触控显示器、触控平板电脑或者触控电视。例如，图9中所示触控显示装置200即为触控手机。Optionally, in the embodiment of the present invention, the specific type of the touch display device is not limited, and may be a touch mobile phone, a touch display, a touch tablet computer or a touch TV.
