These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section.
Fig. 1 is a schematic diagram depicting an in-cell touch display panel 100 according to some embodiments of the invention. The in-cell touch display panel 100 has a display area AA and a peripheral area PA outside and surrounding the display area AA. The display area AA has touch driving electrodes TX (1) -TX (8) and touch sensing electrodes RX (1) -RX (10), wherein the touch driving electrodes TX (1) -TX (8) and the touch sensing electrodes RX (1) -RX (10) are arranged perpendicular to each other. The touch driving electrodes TX (1) -TX (8) and the touch sensing electrodes RX (1) -RX (10) may be made of a transparent conductive material, such as Indium Tin Oxide (ITO) or Indium Zinc Oxide (IZO), but are not limited thereto. The peripheral area PA has a driving circuit D electrically connected to the touch driving electrodes TX (1) -TX (8) and the touch sensing electrodes RX (1) -RX (10) to transmit sensing signals to the touch driving electrodes TX (1) -TX (8) and simultaneously detect the touch sensing electrodes RX (1) -RX (10). When an object (e.g., a human finger, a stylus, etc.) is operated on the embedded touch display panel 100, capacitance values between the touch driving electrodes TX (1) -TX (8) and the touch sensing electrodes RX (1) -RX (10) are changed. Detecting the change in capacitance values between the touch driving electrodes TX (1) -TX (8) and the touch sensing electrodes RX (1) -RX (10) via the driving circuit D can determine the position of the object in the embedded touch display panel 100.
In some embodiments, in addition to providing the touch driving function, the driving circuit D further provides a pixel driving function for driving each pixel (not shown) in the display area AA to make the display area AA display a corresponding image. Each pixel in the display area AA has a common electrode (not shown). In some embodiments, a portion of the common electrodes constitute touch driving electrodes TX (1) -TX (8), and another portion of the common electrodes constitute touch sensing electrodes RX (1) -RX (10). For the in-cell touch display panel 100, each frame (frame) can be divided into a display phase and a touch sensing phase. In the display phase, the driving circuit D provides a pixel voltage and a common voltage to a pixel electrode (not shown) and a common electrode of each pixel, so as to display a corresponding frame in the display area AA. In the touch sensing phase, the driving circuit D provides sensing signals to the touch driving electrodes TX (1) to TX (8) and simultaneously detects the touch sensing electrodes RX (1) to RX (10). How the driving circuit D operates in the display stage and the touch sensing stage is not the focus of the present invention, and therefore, not described herein.
As shown in fig. 1, the virtual center line C divides the in-cell touch display panel 100 into two symmetrical regions, wherein one region includes the touch driving electrodes TX (1) -TX (4) and the touch sensing electrodes RX (1) -RX (5), and the other region includes the touch driving electrodes TX (5) -TX (8) and the touch sensing electrodes RX (6) -RX (10). Every two touch driving electrodes symmetrically arranged in the two areas form a touch driving electrode group, and the two groups are electrically connected with each other. That is to say, the touch driving electrode TX (1) and the touch driving electrode TX (8) form a touch driving electrode group P1, and the touch driving electrode TX (1) and the touch driving electrode TX (8) are electrically connected; the touch driving electrode TX (2) and the touch driving electrode TX (7) form a touch driving electrode group P2, and the touch driving electrode TX (2) and the touch driving electrode TX (7) are electrically connected; the touch driving electrode TX (3) and the touch driving electrode TX (6) form a touch driving electrode group P3, and the touch driving electrode TX (3) and the touch driving electrode TX (6) are electrically connected; the touch driving electrode TX (4) and the touch driving electrode TX (5) form a touch driving electrode group P4, and the touch driving electrode TX (4) and the touch driving electrode TX (5) are electrically connected.
In some embodiments, as shown in fig. 1, each of the touch driving electrodes TX (1) to TX (8) has a corresponding touch driving electrode lead L (1) to L (8). The touch driving electrode leads L (1) -L (8) are respectively coupled to the touch driving electrodes TX (1) -TX (8), and the touch driving electrode leads L (1) -L (8) extend to the peripheral area PA. In the peripheral area PA, the touch driving electrode leads corresponding to all the touch driving electrodes of the same touch driving electrode group are coupled to the same connecting wire. As shown in fig. 1, there are four connection wires W1(1) -W1 (4) in the peripheral area PA, in which touch drive electrode leads L (1) and L (8) are coupled to the connection wire W1(1), touch drive electrode leads L (2) and L (7) are coupled to the connection wire W1(2), touch drive electrode leads L (3) and L (6) are coupled to the connection wire W1(3), and touch drive electrode leads L (4) and L (5) are coupled to the connection wire W1 (4).
In the embedded touch display panel 100, the touch driving electrode leads L (1) -L (8) and the connecting leads W1(1) -W1 (4) may be made of a conductive material, which is the same as a circuit component (not shown) in the display area AA, and the touch driving electrode leads L (1) -L (8) and the connecting leads W1(1) -W1 (4) may be formed by the same process as a circuit component (not shown) in the display area AA. In addition, in some embodiments, the touch driving electrode leads L (1) to L (8) and the connection leads W1(1) to W1(4) may be direct contacts. For example, the touch driving electrode leads L (1) and L (8) may be in direct contact with the connection wire W1(1) through the via.
In the embodiment of fig. 1, all touch driving electrodes in the same touch driving electrode group can be electrically connected through the connecting wires disposed in the peripheral area PA. Therefore, all the touch driving electrodes in the same touch driving electrode group can provide the same voltage value in the display stage, which is beneficial to the voltage equalization of the touch driving electrodes in the display stage. In addition, all the touch driving electrodes in the same touch driving electrode group are electrically connected to each other through the connecting wires arranged in the peripheral area PA, and no additional components or circuits are added in the display area AA, so that the overall process and light transmittance of the display area AA are not affected. Furthermore, the connecting wires disposed in the peripheral area PA and the circuit elements (not shown) in the display area AA can be formed by the same process, so that the overall process steps of the in-cell touch display panel 100 are not increased.
It should be noted that the number of the connecting wires and the connection relationship between the connecting wires and the touch driving electrode leads L (1) to L (8) depicted in fig. 1 are only for illustration and are not intended to limit the scope of the present invention. For example, in other embodiments, two connection wires may be disposed in the peripheral region of the embedded touch display panel 100, wherein one of the connection wires is coupled to the touch driving electrode leads L (1), L (2), L (7) and L (8), and the other connection wire is coupled to the touch driving electrode leads L (3) -L (6). Thus, any embodiments derived from the disclosure are intended to be within the scope of the invention.
Fig. 2 is a schematic diagram depicting an in-cell touch display panel 200 according to some embodiments of the invention. The in-cell touch display panel 200 has a display area AA and a peripheral area PA outside and surrounding the display area AA. The display area is provided with touch driving electrodes TX (1) -TX (8) and touch sensing electrodes RX (1) -RX (10), wherein the touch driving electrodes TX (1) -TX (8) and the touch sensing electrodes RX (1) -RX (10) are arranged perpendicular to each other. The peripheral area PA has a driving circuit D electrically connected to the touch driving electrodes TX (1) -TX (8) and the touch sensing electrodes RX (1) -RX (10) to transmit sensing signals to the touch driving electrodes TX (1) -TX (8) and simultaneously detect the touch sensing electrodes RX (1) -RX (10). The configurations of the touch driving electrodes TX (1) -TX (8), the touch sensing electrodes RX (1) -RX (10) and the driving circuit D in fig. 2 are the same as those in fig. 1, so that the related descriptions refer to the previous paragraphs and are not repeated herein.
In some embodiments, in addition to providing the touch driving function, the driving circuit D further provides a pixel driving function for driving each pixel (not shown) in the display area AA to make the display area AA display a corresponding image. Each pixel in the display area AA has a common electrode (not shown). In some embodiments, a portion of the common electrodes form touch driving electrodes TX (1) -TX (8), and another portion of the common electrodes form touch sensing electrodes RX (1) -RX (10).
As shown in fig. 2, each of the touch driving electrodes TX (1) to TX (8) has a corresponding touch driving electrode lead L (1) to L (8). The touch driving electrode leads L (1) -L (8) are respectively coupled to the touch driving electrodes TX (1) -TX (8), and the touch driving electrode leads L (1) -L (8) respectively extend from two ends of the touch driving electrodes TX (1) -TX (8) to the peripheral area PA, wherein one ends of the touch driving electrode leads L (1) -L (8) are coupled to the driving circuit D. In the peripheral area PA, two ends of the same touch driving electrode are coupled to the same connecting wire. As shown in fig. 2, there are eight connection wires W2(1) -W2 (8) in the peripheral area PA, which are respectively coupled to two ends of the corresponding touch drive electrode leads L (1) -L (8). That is, the connection wire W2(i) is coupled to both ends of the touch driving electrode lead l (i).
In some embodiments, as shown in fig. 2, the virtual center line C divides the in-cell touch display panel 200 into two symmetrical regions, wherein one region includes the connecting wires W2(1) -W2 (4), and the other region includes the connecting wires W2(5) -W2 (8). In fig. 2, the connection wire W2(1) and the connection wire W2(8) are linearly symmetrical, the connection wire W2(2) and the connection wire W2(7) are linearly symmetrical, the connection wire W2(3) and the connection wire W2(6) are linearly symmetrical, and the connection wire W2(4) and the connection wire W2(5) are linearly symmetrical. In other embodiments, the connecting wires W2(1) -W2 (8) may be located on the same side of the in-cell touch display panel 200.
In the in-cell touch display panel 200, the touch driving electrode leads L (1) -L (8) and the connecting leads W2(1) -W2 (8) may be formed of a conductive material, which is the same as a circuit element (not shown) in the display area AA, and the touch driving electrode leads L (1) -L (8) and the connecting leads W1(1) -W2 (8) may be formed by the same process as a circuit element (not shown) in the display area AA. In addition, in some embodiments, the touch driving electrode leads L (1) to L (8) and the connecting leads W2(1) to W2(8) may be in direct contact. For example, two ends of the touch driving electrode lead L (1) may be directly contacted with the connection wire W2(1) through the via.
In the embodiment of fig. 2, the connection wires disposed in the peripheral area PA can provide another electrical connection path at two ends of each touch driving electrode, and can reduce the impedance of the side of the touch driving electrode away from the driving circuit D to the driving circuit D. Therefore, all the common electrodes in the same touch driving electrode can easily reach the target voltage value in the display stage, and all the common electrodes in the same touch driving electrode can provide the same voltage value in the display stage, which is beneficial to the voltage equalization of the touch driving electrode in the display stage. In addition, two ends of each touch driving electrode are electrically connected with each other through a connecting wire arranged in the peripheral area PA, and no additional component or circuit is arranged in the display area AA, so that the overall process, the light transmittance and the like of the display area AA are not influenced. Furthermore, the connecting wires disposed in the peripheral area PA and the circuit elements (not shown) in the display area AA can be formed by the same process, so that the overall process steps of the in-cell touch display panel 200 are not increased.
In some embodiments, the in-cell touch display panel may have the connection wires W1(1) -W1 (4) shown in fig. 1 and the connection wires W2(1) -W2 (8) shown in fig. 2. Referring to fig. 3, fig. 3 is a schematic diagram illustrating an in-cell touch display panel 300 according to some embodiments of the invention. Compared to the in-cell touch display panel 100 of fig. 1, the in-cell touch display panel 300 of fig. 3 further includes the connecting wires W2(1) -W2 (8) shown in fig. 2. In fig. 3, the configurations of the touch driving electrodes TX (1) to TX (8), the touch sensing electrodes RX (1) to RX (10), the driving circuit D and the connecting wires W1(1) to W1(4) are the same as those in fig. 1, and the configurations of the connecting wires W2(1) to W2(8) are the same as those in fig. 2, so that the related descriptions refer to the previous paragraphs, which are not repeated herein.
