Thus, the connecting line 7 is disposed in the touch area, thereby further avoiding the problem that the connecting line 7 is disposed in the peripheral area and the frame is wide. At the same time, the connecting line 7 can be flexibly arranged in the touch area, is convenient to manufacture, and reduces the manufacturing cost.
例如,所述连接线7在所述第一电极层的正投影位于相邻的感应电极之间。这样,可以避免连接线7设置在周边导致的边框较宽的问题,而且能够减弱连接线7的信号对感应电极信号的影响。For example, the orthographic projection of the connecting line 7 at the first electrode layer is between adjacent sensing electrodes. In this way, it is possible to avoid the problem that the connecting line 7 is disposed at a periphery to cause a wide border, and it is possible to weaken the influence of the signal of the connecting line 7 on the sensing electrode signal.
例如,根据本发明实施例的触控基板还包括位于所述第一电极层的远离所述第二电极层的一侧的第二绝缘层5,所述连接线7通过位于第二绝缘层5上与所述感应电极4位置相对应的过孔9与所述感应电极4连接。For example, the touch substrate according to the embodiment of the present invention further includes a second insulating layer 5 on a side of the first electrode layer away from the second electrode layer, and the connecting line 7 passes through the second insulating layer 5 A via 9 corresponding to the position of the sensing electrode 4 is connected to the sensing electrode 4.
通过将连接线7与感应电极4不同层布置,使连接线7的布置更加灵活、自由,便于从触控基板的同一侧引出连接线7。By arranging the connecting wires 7 and the sensing electrodes 4 in different layers, the arrangement of the connecting wires 7 is more flexible and free, and the connecting wires 7 are easily taken out from the same side of the touch substrate.
这样,连接线7的图形可以综合考虑寄生电容、杂讯、可视性等因素来设计各种图案,从而无需从边框走线,实现无边框设计。也就是说,连接线7可以按实际需要布置(只要不相交),例如,为了减少各连接线7的长度可以采用直线式的平行布置。In this way, the pattern of the connecting line 7 can be designed into various patterns by considering factors such as parasitic capacitance, noise, visibility, etc., thereby eliminating the need for routing from the frame and achieving a borderless design. That is to say, the connecting lines 7 can be arranged as needed (as long as they do not intersect), for example, in order to reduce the length of each connecting line 7, a linear parallel arrangement can be employed.
如图2所示(图2中示出部分连接线7),例如,每行所述感应电极4通过一根连接线7引出;每列所述感应电极4通过一根连接线7引出。As shown in FIG. 2 (partial connecting line 7 is shown in FIG. 2), for example, the sensing electrodes 4 are led out by a connecting line 7 per row; and each of the sensing electrodes 4 is led out by a connecting line 7.
由于每行或每列感应电极4传输相同的触控驱动信号或触控检测信号,可以将每行或每列相互连接的感应电极4通过一个连接线7引出。Since each row or column of sensing electrodes 4 transmits the same touch driving signal or touch detection signal, the sensing electrodes 4 connected to each row or column can be led out through a connecting line 7.
如图1和2所示,例如,所述第二绝缘层5上设有凹槽10(图1中被连接线7和信号屏蔽层6填充的部分),所述凹槽10的一端以所述过孔9为起 点延伸至所述触控基板的同一侧。图2中凹槽10为网格线部分,凹槽10至少部分被连接线7覆盖。As shown in FIGS. 1 and 2, for example, the second insulating layer 5 is provided with a recess 10 (a portion filled with the connecting line 7 and the signal shielding layer 6 in FIG. 1), and one end of the recess 10 is Said via 9 The dots extend to the same side of the touch substrate. The groove 10 in Fig. 2 is a grid line portion, and the groove 10 is at least partially covered by the connecting line 7.
上述的凹槽10用于设置连接线7,便于通过网版印刷形成连接线7,连接线7从过孔9处与感应电极4连接,同时从触控基板的同一侧引出。The above-mentioned groove 10 is used for arranging the connecting wire 7 to facilitate the formation of the connecting wire 7 by screen printing. The connecting wire 7 is connected from the via hole 9 to the sensing electrode 4 while being drawn from the same side of the touch substrate.
例如,所述凹槽10在第一电极层的正投影位于所述感应电极4之间。这样,在凹槽10内设置连接线7时,能减少连接线7内的驱动信号或检测信号对触控检测造成的影响。For example, an orthographic projection of the groove 10 at the first electrode layer is located between the sensing electrodes 4. Thus, when the connection line 7 is provided in the recess 10, the influence of the drive signal or the detection signal in the connection line 7 on the touch detection can be reduced.
如图2所示,例如,各连接线7平行布置,方便连接线7的制作。As shown in FIG. 2, for example, the respective connecting wires 7 are arranged in parallel to facilitate the production of the connecting wires 7.
例如,所述连接线7是采用透明导电材料制备的。这样,能增加触控基板的透光率。For example, the connecting line 7 is made of a transparent conductive material. In this way, the light transmittance of the touch substrate can be increased.
例如,所述连接线7是采用纳米银材料制备的。由于连接线7采用纳米银材料制备,在保证透明的情况下能降低连接线7的方阻。For example, the connecting line 7 is made of a nanosilver material. Since the connecting wire 7 is made of a nano silver material, the square resistance of the connecting wire 7 can be reduced while ensuring transparency.
例如,所述凹槽10底面上设有信号屏蔽层6。例如,信号屏蔽层6采用透明材料制备。For example, a signal shielding layer 6 is disposed on the bottom surface of the recess 10. For example, the signal shielding layer 6 is made of a transparent material.
例如,所述信号屏蔽层6具有粗糙的表面。由于信号屏蔽层6具有粗糙的表面,在屏蔽信号的同时,又可以利用光的散射起到消影的作用。For example, the signal shielding layer 6 has a rough surface. Since the signal shielding layer 6 has a rough surface, the scattering of the light can be used to eliminate the shadow while shielding the signal.
例如,所述信号屏蔽层6的表面具有沟槽或突起。利用光在沟槽或突起上的散射起到消影的作用。应当理解的,其它类型的粗糙表面也是可行的。For example, the surface of the signal shielding layer 6 has grooves or protrusions. The use of light scattering on the grooves or protrusions acts as a shadow. It should be understood that other types of rough surfaces are also possible.
例如,所述连接线7设置于所述信号屏蔽层6上。这样能充分利用凹槽10区域降低触控基板厚度。For example, the connection line 7 is disposed on the signal shielding layer 6. This can make full use of the groove 10 area to reduce the thickness of the touch substrate.
