Optionally, the length of each side of the corresponding second mesh blocks in the plurality of second mesh electrodes MB2 is approximately 2.0 mm.

[0066] Figure 5 Schematic diagram showing the structure of the touch structure in some embodiments of the present disclosure. Figure 5 , the corresponding first mesh blocks in the plurality of first mesh electrodes MB1 have a pseudo square shape, and the corresponding second mesh blocks in the plurality of second mesh electrodes MB2 have a pseudo square shape. Figure 5 In the touch structure, each side of a corresponding first mesh block in the plurality of first mesh electrodes MB1 has a length of approximately 4.0 mm, and each side of a corresponding second mesh block in the plurality of second mesh electrodes MB2 has a length of approximately 4.0 mm. Figure 5 The grid blocks in the touch structure occupy an area of ​​approximately Figure 1 、 Figure 4A and Figure 4B The area occupied by the grid blocks in the touch structure is four times that of the grid blocks in the touch structure. Figure 5 In the touch structure of , in the 4.0mm×4.0mm area occupied by the corresponding grid block, the first mesh electrode and the second mesh electrode do not cross, and the mutual capacitance in the inner part of the 4.0mm×4.0mm area occupied by the corresponding grid block is small. However, around the vertices of the 4.0mm×4.0mm area occupied by the corresponding grid block, the mutual capacitance is relatively large due to its proximity to the intersection position of the first mesh electrode and the second mesh electrode. Therefore, the value of the mutual capacitance varies greatly on the line between the two opposite vertices of the 4.0mm×4.0mm area occupied by the corresponding grid block, resulting in poor linearity. For example, an active stylus typically has a relatively small contact area (typically a contact point). When an active stylus is used on the inner part of the 4.0mm×4.0mm area occupied by the corresponding grid block, it is quite difficult to achieve accurate touch due to the relatively small mutual capacitance in this part.

[0067] Compared to Figure 5In some embodiments, the touch structure Figure 1 The touch structure has four mesh electrodes in an area of ​​4.0 mm × 4.0 mm. Figure 1 , the 4.0mm×4.0mm area is occupied by R1MB1, R1MB2, R2MB1 and R2MB2. Figure 1 In the touch structure of , the intersection of the first mesh electrode and the second mesh electrode exists not only at the apex of the 4.0mm×4.0mm area, but also in the inner part of the 4.0mm×4.0mm area. Figure 5 The touch structure of Figure 1 The touch structure of the embodiment of FIG1 can achieve a uniformly distributed mutual capacitance in the entire 4.0 mm × 4.0 mm area. When the active stylus is used on the inner part of the 4.0 mm × 4.0 mm area, a more accurate touch performance can be obtained due to the highly enhanced mutual capacitance uniformity in the entire 4.0 mm × 4.0 mm area. Table 1 summarizes the mutual capacitance uniformity according to FIG1.

[0070] As shown in Table 1, compared with Figure 5 The embodiment of the touch structure according to Figure 1 The embodiment of the touch structure achieves a significantly larger △Cm value (increased by more than 70%), which can achieve highly accurate touch performance. Figure 1 The mesh electrode of the touch structure of the embodiment according to Figure 5 Compared with the mesh electrodes of the touch sensing structure of the embodiment, the mesh electrodes have much lower resistance, resulting in a significantly lower RC load value. The lower RC load value significantly improves the following performances: touch scanning electrode driving frequency and signal-to-noise ratio.

Figure 6A and Figure 6B As shown, when the active stylus spans the area from point A to point B, the touch signal has relatively large variability. Figure 7A yes Figure 1A magnified view of an area within the touch structure. Figure 7B Shows when using an active stylus Figure 7A The value of △Cm at both ends of the area. Figure 7A and Figure 7B As shown in FIG, when the active stylus spans the area from point A to point B, the touch signal has relatively little variability and greatly enhanced uniformity. Three active styluses with different contact areas (2.5 pitch, 2.0 pitch, and 2.25 pitch) are used. Figure 6B and Figure 7B As shown, according to Figure 1 Embodiments of the touch sensing structure achieve enhanced touch performance regardless of the contact area of ​​the active stylus.
