And the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

[0028] A touch display panel provided by an embodiment of the present invention, as Figures 1 - 4 shown, Figure 1 and Figure 3 are top views of the touch display panel, Figure 2 is Figure 1 the layout of a partial area in Figure 4 is Figure 3 the layout of a partial area in . The touch display panel includes a display substrate and a plurality of touch units. The display substrate includes: a substrate substrate 1, a plurality of rows and columns of sub-pixel units (P1, P2, P3...) located on the substrate substrate 1, a plurality of data lines (D1, D2, D3...) electrically connected to each column of sub-pixel units one by one, and a plurality of touch electrode traces (L1, L2, L3...) electrically connected to each touch unit one by one; the touch unit includes a plurality of touch electrode blocks electrically connected to each other, Figure 1Taking six touch units as an example, where each touch unit includes nine touch electrode blocks. The first touch unit includes nine touch electrode blocks T1 - T9, the second touch unit includes nine touch electrode blocks T10 - T18, the third touch unit includes nine touch electrode blocks T19 - T27, the fourth touch unit includes nine touch electrode blocks T28 - T36, the fifth touch unit includes nine touch electrode blocks T37 - T45, and the sixth touch unit includes nine touch electrode blocks T46 - T54. Two touch electrode traces are correspondingly arranged between two adjacent data lines. For example, two touch electrode traces L1 and L2 are arranged between adjacent data lines D1 and D2. L1 is electrically connected to the first touch unit and led out to the peripheral driving circuit (not shown), and L2 is electrically connected to the third touch unit and led out to the peripheral driving circuit. Two touch electrode traces L3 and L4 are arranged between adjacent data lines D4 and D5. L3 is electrically connected to the second touch unit and led out to the peripheral driving circuit, and L4 is electrically connected to the fourth touch unit and led out to the peripheral driving circuit, and so on. The distance between the two touch electrode traces between two adjacent data lines is less than the distance between the touch electrode trace and the adjacent data line. For example, the distance d1 between the two touch electrode traces L1 and L2 between adjacent data lines D1 and D2 is less than the distance d2 between the touch electrode trace L1 and the adjacent data line D1. And the distances from the two touch electrode traces between two adjacent data lines to their respective adjacent data lines are not equal. For example, the distance d2 between the touch electrode trace L1 and the adjacent data line D1 and the distance d3 between the touch electrode trace L2 and the adjacent data line D2 between adjacent data lines D1 and D2 are not equal.

[0029] In the touch display panel provided by the embodiment of the present invention, by correspondingly arranging two touch electrode traces between two adjacent data lines, and the distance between the two touch electrode traces between two adjacent data lines is less than the distance between the touch electrode trace and the adjacent data line, and the distances from the two touch electrode traces between two adjacent data lines to their respective adjacent data lines are not equal, the touch electrode traces can be distributed as evenly as possible within the area where the touch electrodes are located, improving the problem of uneven distribution of the touch electrode traces, so as to improve the uniformity of touch and display of the display device including the touch display panel. Moreover, the touch electrode blocks in the same row are spaced from each other, and the touch electrode blocks in the same column are spaced from each other, so that the touch electrode blocks are evenly distributed.

[0030] In the embodiment of the present invention, the display substrate may be an array substrate, but is not limited thereto.

[0031] In the embodiment of the present invention, as Figure 1As shown, gate lines (G1, G2, G3...) arranged crosswise with data lines (D1, D2, D3...) are further provided on the array substrate. The gate lines (G1, G2, G3...) and the data lines (D1, D2, D3...) enclose multiple rows and multiple columns of sub-pixel units (P1, P2, P3...).

[0032] In a specific implementation, the touch electrode block can be a capacitor block, but is not limited thereto.

[0033] In a specific implementation, the sub-pixel unit can include a red (R) sub-pixel unit, a green (G) sub-pixel unit, and a blue (B) sub-pixel unit, but is not limited thereto.

[0034] In a specific implementation, as Figure 1 and Figure 3 shown, the shapes and sizes of each touch electrode block included in the touch unit can be the same, and the size of the touch electrode block is not greater than the size of the corresponding sub-pixel unit, but is not limited thereto. In the embodiments of the present invention Figure 1 and Figure 3 the touch electrode block is taken as an example of a regular square block for illustration, but in the actual manufacturing process, the shape of each touch electrode block is irregular, as Figure 2 and Figure 4 shown, Figure 2 and Figure 4 both illustrate 8 touch electrode blocks (shown in braces), Figure 2 and Figure 4 are layout schematic diagrams closer to the actual manufacturing process, and it can be seen that the touch electrode block is not in a regular shape.

[0035] In a specific implementation, in the above touch display panel provided by the embodiments of the present invention, as Figure 1 and Figure 2 shown, the orthographic projection of the data lines (D1, D2, D3...) on the substrate 1 does not overlap with the orthographic projection of the touch electrode blocks (T1-T54) on the substrate 1. Thus, during the touch stage, there is no coupling capacitance between the touch electrode block and the data line, improving the response speed of the touch display.

[0036] In a specific implementation, in the above touch display panel provided by the embodiments of the present invention, as Figure 1 and Figure 2As shown, the orthographic projection of the touch electrode block on the substrate is located within the orthographic projection of the corresponding sub-pixel unit on the substrate. For example, the orthographic projection of the touch electrode block T1 on the substrate 1 is located within the orthographic projection of the corresponding sub-pixel unit P1 on the substrate 1, the orthographic projection of the touch electrode block T2 on the substrate 1 is located within the orthographic projection of the corresponding sub-pixel unit P2 on the substrate 1, the orthographic projection of the touch electrode block T3 on the substrate 1 is located within the orthographic projection of the corresponding sub-pixel unit P3 on the substrate 1, and so on. This can further ensure that the orthographic projection of the touch electrode block on the substrate does not overlap with the orthographic projection of the data line on the substrate. Thus, during the touch stage, there is no coupling capacitance between the touch electrode block and the data line, further improving the response speed of the touch display.

[0037] In specific implementation, in the above touch display panel provided by the embodiments of the present invention, as Figure 1 and Figure 2 shown, the touch electrode blocks are arranged in one-to-one correspondence with the sub-pixel units. For example, T1 corresponds to P1, T2 corresponds to P2, T3 corresponds to P3, and so on. The sub-pixel unit (such as P1) includes a pixel electrode (not shown) electrically connected to the data line D2, and the orthographic projection of the touch electrode block T1 on the substrate 1 is located within the orthographic projection of the corresponding pixel electrode on the substrate 1. This can evenly distribute the touch electrode blocks and further improve the uniformity of touch and display of the touch display panel.

[0038] In specific implementation, in the above touch display panel provided by the embodiments of the present invention, as Figure 1 and Figure 2 shown, the orthographic projection of the touch electrode trace (such as L1) on the substrate 1 intersects with the orthographic projection of the touch electrode block (the leftmost column of touch electrode blocks) on the substrate 1.

[0039] In specific implementation, in the above touch display panel provided by the embodiments of the present invention, as Figure 3 and Figure 4 shown, the orthographic projections of the data lines (D1, D2, D3...) on the substrate 1 may intersect with the orthographic projections of the touch electrode blocks (T1 - T54) on the substrate 1.

[0040] In specific implementation, in the above touch display panel provided by the embodiments of the present invention, as Figure 3 and Figure 4As shown, each sub-pixel unit (e.g., P1) includes a pixel electrode (not shown) electrically connected to the data line D2. The orthographic projection of a pixel electrode (e.g., the pixel electrode within P1) on the substrate 1 overlaps with the orthographic projections of two touch electrode blocks (T1 and T2) on the substrate 1. With such a design, the orthographic projection of the touch electrode trace on the substrate 1 can be located at the gap between two adjacent columns of touch electrode blocks. Therefore, in specific implementation, in the above touch display panel provided by the embodiments of the present invention, as Figure 1 shown, the orthographic projection of the touch electrode trace (e.g., L2) on the substrate 1 is located at the gap between two adjacent columns of touch electrode blocks (the second column and the third column from the left). In this way, during the touch stage, there is no coupling capacitance between the touch electrode blocks and the touch electrode trace, further improving the response speed of touch display.

[0041] In specific implementation, in the above touch display panel provided by the embodiments of the present invention, as Figure 2 and Figure 4 shown, the touch electrode traces (L1, L2, L3, L4...) and the data lines (D1, D2, D3, D4, D5...) are arranged on the same layer. The touch electrode traces and the data lines adopt the same filling pattern, indicating that they are on the same layer. The touch electrode traces and the data lines can be designed side by side. In this way, only by changing the original layout pattern when forming the data lines, the patterns of the touch electrode traces and the data lines can be formed through one lithography process, without adding a separate process for preparing the touch electrode traces, which can simplify the manufacturing process, save production costs, and improve production efficiency.

[0042] In specific implementation, the touch unit is arranged on the upper layer of the data line, that is, the touch unit and the data line are on different layers, so that the touch unit and the touch electrode trace are overlapped through vias.

[0043] In specific implementation, in the above touch display panel provided by the embodiments of the present invention, it further includes a common electrode layer. The common electrode layer includes a plurality of common electrode blocks, and the common electrode blocks are multiplexed as Figure 1 and Figure 3 shown touch electrode blocks. In this way, a separate process for preparing the touch electrode blocks does not need to be added, which can reduce the thickness of the touch display panel, save production costs, and improve production efficiency.

[0044] In specific implementation, the touch unit loads a common voltage signal during the display period and loads a touch signal during the touch period to implement a touch display panel with integrated touch and display. That is, the touch electrode and the common electrode are multiplexed.

[0045] In the embodiments of the present invention, the touch electrode block can be a self-capacitive touch electrode or a mutual-capacitive touch electrode. When the touch electrode block is a mutual-capacitive touch electrode, it can be used as a touch driving electrode in the mutual-capacitive touch electrode.

[0046] In specific implementation, in the above-mentioned touch display panel provided by the embodiments of the present invention, as Figure 1 and Figure 3 shown, the common electrode layer further includes a connection electrode 2, and the touch electrode blocks in each touch unit are electrically connected through the connection electrode 2. For example, the nine touch electrode blocks T1-T9 in the first touch unit are electrically connected to each other through the connection electrode 2.

[0047] In specific implementation, in the above-mentioned touch display panel provided by the embodiments of the present invention, as Figure 1 and Figure 3 shown, among the touch electrode blocks in each touch unit, the touch electrode blocks arranged in the row direction are respectively electrically connected in pairs through the corresponding connection electrode 2, and the touch electrode blocks arranged in the column direction are respectively electrically connected in pairs through the corresponding connection electrode 2. Since the connection electrode 2 also affects touch and display, the setting method of the connection electrode 2 in the present invention can ensure that the connection electrode 2 is evenly distributed in the touch display panel, further improving the uniformity of display and touch.

[0048] In specific implementation, in the above-mentioned touch display panel provided by the embodiments of the present invention, as Figure 1 and Figure 3 shown, the number of touch units is multiple. In the present invention, only 6 are schematically shown. In specific implementation, there are far more than 6, and the number of touch electrode blocks in each touch unit is the same. In the embodiments of the present invention, an example is given that each touch unit includes 9 touch electrode blocks, but of course it is not limited thereto. Such an arrangement makes the distribution of the touch electrode blocks very uniform, further improving the uniformity of touch and display.

[0049] In specific implementation, in the above-mentioned touch display panel provided by the embodiments of the present invention, each touch unit may include M×N touch electrode blocks, where M and N are both natural numbers greater than or equal to 2.

[0050] For example, the length of the touch unit in the row direction can correspond to three sub-pixel units, and the length in the column direction can correspond to three sub-pixel units; the length of the touch unit in the row direction can correspond to six sub-pixel units, and the length in the column direction can correspond to three sub-pixel units. The number of sub-pixel units corresponding to the touch unit in the row direction and the column direction is not limited and is designed according to actual needs.

[0051] It should be noted that the touch display panel provided in the embodiments of the present invention can be specifically applied to a liquid crystal display panel (LCD), or can also be applied to an organic light-emitting diode display panel (OLED), or can also be applied to other display panels, which is not limited herein.

For example, it is of great significance for MPP 2.0 and 2mm passive pens and higher requirements.

The display device can be: a mobile phone, a tablet computer, a television, a monitor, a laptop computer, a digital photo frame, a navigator, or any other product or component with a display function. Other essential components of the display device are understood by those of ordinary skill in the art and will not be elaborated herein, nor should they be regarded as a limitation to the present invention. The principle of solving problems of the display device is similar to that of the aforementioned quantum dot light-emitting device. Therefore, the implementation of the display device can refer to the implementation of the aforementioned touch display panel, and the repeated parts will not be elaborated herein.

[0054] A touch display panel and a display device provided in the embodiments of the present invention are configured such that two touch electrode traces are correspondingly arranged between two adjacent data lines, the distance between the two touch electrode traces between two adjacent data lines is less than the distance between the touch electrode trace and the adjacent data line, and the distances between the two touch electrode traces between two adjacent data lines and their respective adjacent data lines are not equal. Thus, each touch electrode trace can be distributed as evenly as possible within the area where the touch electrodes are located, improving the problem of uneven distribution of touch electrode traces, so as to improve the uniformity of touch and display of the display device including the touch display panel. Moreover, the touch electrode blocks in the same row are spaced from each other, and the touch electrode blocks in the same column are spaced from each other, so that the touch electrode blocks are evenly distributed.
