Fig. 2 is a schematic diagram of a touch display device 20 according to a preferred embodiment of the invention. Referring to fig. 2, the touch display device 20 includes a substrate 200 and a touch display integrated driving circuit 201. The substrate 200 includes a plurality of pixels 202, a plurality of touch/display common voltage electrodes 203, a conductive line 204, and a pad (not shown) for configuring the touch display integrated driving circuit 201. The conductive line 204 is used to electrically connect the touch display integrated driving circuit 201 and the pixel 202, and the touch/display common voltage electrode 203. In this embodiment, each pixel 202 includes red, green, and blue sub-pixels 202-1, 202-2, and 202-3, and the touch/display common voltage electrode 203 can cover a plurality of pixels 202.
Fig. 3 is a configuration diagram of an external Lead Bonding (OLB) of an Integrated circuit (IDC) 300 according to a preferred embodiment of the invention. Referring to fig. 3, reference numeral 301 denotes the bonding position of the outer leads for touch/display common voltage; symbol 302 represents the source driven outer lead bonding location. For convenience of illustration, the X-axis and the Y-axis are also labeled in the drawings. The outer lead bonding locations 301 of the touch display common voltage of the touch display integrated driving circuit 300 are arranged along the first direction (X-axis direction). In addition, the outer lead bonding positions 302 of the display driver of the touch display integrated driving circuit 300 are also arranged along the first direction. In one embodiment, the outer lead bonding positions 302 of the display driver may be arranged in three rows along the second direction (Y-axis direction). It can also be said that the outer lead bonding positions 302 of the three display drivers are arranged in a group.
As can be seen from the configuration diagram of the external pin bonding of the touch display integrated driving circuit 300, the external pin bonding positions 301 of each touch/display common voltage can be equally spaced and arranged along the same direction, so that the crossing of the traces connecting the external pin bonding positions 302 of the display driver from the panel display area pull lines to the external pin bonding positions 301 of the touch/display common voltage can be avoided, and therefore, the panel pull lines corresponding to the external pin bonding positions 301 of the touch/display common voltage and the panel pull lines corresponding to the external pin bonding positions 302 of the display driver can be prepared by using a metal layer and arranged on the same plane.
Fig. 4 is a configuration diagram of a touch display device according to a preferred embodiment of the invention. In this embodiment, the touch display device may include a substrate 401, and the substrate 401 includes, for example, a plurality of touch/display common voltage electrodes 402, a plurality of conductive lines 403, a plurality of pixels 404, and a plurality of pads 405. The substrate 401 may be glass or a flexible plastic material. Also shown in FIG. 4 are pad 405-1 electrically connected to the touch/display common voltage electrode 402 and pad 405-2 electrically connected to a subpixel of pixel 404. As shown in fig. 4, each touch/display common voltage electrode 402 may cover a plurality of pixels 404.
In fig. 4, pads 405-1 electrically connected to the touch/display common voltage electrode 402 may be arranged at equal intervals along the X-axis direction. And between every two pads 405-1, one pad group consisting of, for example, three pads 405-2 electrically connected to the sub-pixels of the pixel 404 may be arranged. In one embodiment, the group of three pads 405-2 may be electrically connected to the sources of the TFTs of the red, green, and blue subpixels of the pixel 404, respectively, for providing display update data.
In this embodiment, the conductive lines 403 electrically connected to each pad 405 in the Y-axis direction may not be interleaved with each other. In other words, each conductive line 403 may be electrically connected to a corresponding pad 405 without crossing other conductive lines 403, including conductive lines located at different layers, without overlapping each other. Accordingly, the conductive line 403 may be disposed in the same layer. However, in a display panel with a higher resolution, such as 720x1280, the number of traces in the source driver includes 2160 lines, and the number of traces may be as high as 2880 lines by adding touch traces or conductive lines, so that two Metal layers (Metal-1 and Metal-2) are used as the layout of the pull lines. Since the external pin bonding of the integrated circuit in an embodiment of the invention can be configured as shown in fig. 3, the traces or conductive lines from the integrated touch display driving circuit 300 to the touch/display common voltage electrodes 402 of the panel do not need to be interleaved with the traces of the sub-pixels. Therefore, as shown in FIG. 4, fan-out (fan out) pull lines between the touch sensing, source driving and touch display panel can be completed by using only two Metal layers (Metal-1 and Metal-2).
To achieve the configuration of the outer lead bonding positions shown in fig. 4 and fig. 3, the circuit configuration inside the touch display integrated driving circuit 300 can be referred to as shown in fig. 5. In the embodiment of FIG. 5, the pad 405-1 electrically connected to the touch/display common voltage electrode 402 is located above (outside) the integrated touch display driver circuit 300, and thus, the touch input/output circuit 501 is also disposed above the integrated touch display driver circuit 300. In this embodiment, the touch input/output circuit 501 and the source driver circuit 502(source driver IC) are configured as a bar type. Similarly, the source driver circuit 502 is also disposed below (inside) the touch display integrated driver circuit 300, following the pad 405-2 electrically connected to the sub-pixel of the pixel 404. Meanwhile, the layout (layout) of the integrated circuit is also long. In addition, some common circuits 503, such as Electrostatic Discharge (ESD), power line (power line), etc., are disposed between the touch input/output circuit 501 and the source driving circuit 502.
The above embodiment exemplifies the case where the pads 405-1 electrically connected to the touch/display common voltage electrode 402 are arranged in the first row (outermost side) in the X-axis direction. If the touch input/output circuit 501 is disposed below the touch display integrated driving circuit 300, the pads 405-1 electrically connected to the touch/display common voltage electrode 402 may be disposed in the last row (innermost) in the X-axis direction, as in the embodiment of fig. 6. In fig. 6, the touch input/output circuit 501 is disposed below the touch integrated driving circuit 300, and the source driving circuit 502 is disposed above the touch integrated driving circuit 300. Similarly, the common circuit 503 is disposed between the touch input/output circuit 501 and the source driving circuit 502.
Fig. 7 is a configuration diagram of a touch display device corresponding to the touch display integrated driving circuit 300 of the embodiment of fig. 6. Referring to fig. 7 and 4, the difference between this embodiment and the embodiment of fig. 4 is that each pad 705-1 electrically connected to the touch/display common voltage electrode 402 is disposed in the last column, and each pad 705-2 electrically connected to the sub-pixel of the pixel 404 is disposed in the 1 st column to the 3 rd column. That is, the pad 705-1 electrically connected to the touch/display common voltage electrode 402 is disposed at the outermost side of the substrate 401, and in fig. 4, the pad 405-2 electrically connected to the sub-pixel is disposed at the outermost side of the substrate 401.
In the above embodiments, the pixel includes three sub-pixels of red R, green G, and blue B. However, it should be understood by those skilled in the art that the sub-pixels of a pixel may also include red R, green G, blue B, white W, etc. therefore, in the above embodiment, four pads 405-2 electrically connected to the sub-pixels of the pixel 404 may be disposed between any two pads 405-1 electrically connected to the touch/display common voltage electrode 402 in the Y-axis direction. Therefore, the present invention is not limited thereto. Specifically, a plurality of pads 405-2 electrically connecting the sub-pixels, for example, three sub-pixels of RGB or four sub-pixels of RGBW, may be disposed between any two adjacent or neighboring pads 405-1. Here, the proximity or the adjacency may mean that the touch/display common voltage electrodes electrically connected to the pads are proximity or the adjacency. It is understood that the number of the pads 405-2 disposed between the pads 405-1 is different according to the number of the electrically connected sub-pixels, and is not limited to the above examples.
In the above embodiment, the touch input/output pins and the outer pin bonding positions are arranged in four rows in the Y direction, and three sub-pixels are arranged between every two pads of the common voltage electrode in the X direction. However, the configuration is not limited to the above. For example, fig. 8A, 8B, 8C and 8B are configuration diagrams of the touch input/output pins and the bonding positions of the outer pins of the touch display device according to a preferred embodiment of the invention. Wherein 801 denotes a pad of the touch/display common voltage electrode, and 802 denotes a pad of the sub-pixel. R denotes a red sub-pixel, G denotes a green sub-pixel, and B denotes a blue sub-pixel. However, the pad 802 labeled RGB in the figure is not limited to transmitting RGB signals. For example, in embodiments where a multiplexer is used, it is also possible to pass a combination of BRG or GBR signals. It is understood that the pad 802 is used for transmitting sub-pixel signals, but not limited to the transmission aspects disclosed in the drawings.
In fig. 8A, three rows are arranged in the Y direction, and two pads 802 of the sub-pixel are arranged between every two pads 801 of the common voltage electrode in the X direction. In fig. 8B, four rows are arranged in the Y direction, and four pads 802 of sub-pixels are disposed between every two pads 801 connected to the voltage electrodes in the X direction, and the four sub-pixels do not belong to the same pixel. In fig. 8C, although four rows are arranged in the Y direction, two pads 802 of the sub-pixel are disposed between two pads 801 connected to the voltage electrodes in the X direction. Similarly, in fig. 8D, although two rows are arranged in the Y direction, three pads 802 of the sub-pixels are disposed between every two pads 801 of the common voltage electrode in the X direction. The configuration of the touch input/output pins and the configuration of the bonding positions of the outer pins belong to selective design, so the invention is not limited to the configuration of the touch input/output pins.
Fig. 9 is a schematic configuration diagram of a touch display device according to a preferred embodiment of the invention. Referring to fig. 9, the substrate of the touch display device includes a bonding Area (bonding Area)91, a Fan-Out Area (Fan Out Area)92, and a display Area (active Area) 93. In this embodiment, each data output pin is electrically connected to three subpixels 1001 of the corresponding pixel through multiplexers 903 and conductive lines 1002 arranged in the fan-out region 92. Therefore, in this embodiment, the red, green and blue data can be output to the red, green and blue sub-pixels 1001 through only one data output pin pad 901. The touch-control integrated driving circuit 300 can divide the display data into red, green and blue data and transmit the red, green and blue data to the corresponding sub-pixels through the data output pin pads 901, the multiplexer 903 and the corresponding conductive lines 1002. In addition, for the pin configuration of the pad 901, reference may be made to fig. 8A to 8D and the corresponding description thereof, which are not repeated herein.
In summary, the spirit of the present invention is to change the circuit layout of the integrated touch display driving circuit, so as to change the pin layout of the integrated touch display driving circuit. Furthermore, on the substrate of the embedded touch display device, the way of inserting and configuring the welding pads for touch sensing and the welding pads for displaying data is utilized, so that the routing on the panel does not need to be staggered, and a few metal layers can be used as fan-out (fan-out) pull wires from the touch display integrated circuit to the embedded touch display panel on the touch display panel. Therefore, the production cost of the touch display integrated panel can be reduced, and the influence on the production yield and efficiency due to the change of the process of the touch display integrated panel is avoided. Meanwhile, the wiring on the panel does not need to be staggered, and the interference caused by staggered wiring in subsequent operation can be avoided.
